Lake Tahoe Area Weather and Snowpack Information

Blowing hard now, snow to come later

2009-11-20T09:00:00.000-08:00

11/20/09 9am

WINTER STORM WARNING issued for Lake Tahoe Basin. 1-10pm Friday

Snowfall totals: 8-16" along the Western Crest of the Tahoe Basin, 3-8" @ lake level.

Forecast on track although there has been further modification of H2O totals for the storm. Local precip forecast shows .77" @ Truckee 6200', .36" @ Mt Rose 7200' and 1.2" @ Blue Canyon 5200'. HPC guidance has a 1.75" bullseye just W-NW of the Tahoe Crest.

Winds are already hitting 90mph along the TSC. In East Truckee, I have had winds steadily increasing and just had a gust of 30.8mph. So it's breezy for sure.

Enjoy the storm!

Speed is a factor

2009-11-19T07:52:00.000-08:00

11/19/09 7:52 am Update nooner

Update to WINTER STORM WARNING issued for Lake Tahoe Basin. 1-10pm Friday

Update snowfall totals: 8-16" along the Western Crest of the Tahoe Basin, 3-8" @ lake level.

Decent winter storm heading for Tahoe, but the limiting factor is not available moisture but the speed at which the system will plow through the Sierra.

Forecast this morning varies still from yesterday in the way of snowfall totals. NWS Sacto is calling 1-2' above 7000'. NWS Reno is calling for 15" above 7000' and 8" on the West Shore of Lake Tahoe with lesser amounts East of the crest. I believe Sacto is going bigger because looking at the HPC H2O forecast there is a 1.95" bullseye NW of Tahoe and a 1.20" bullseye SW of Tahoe. The Sacto forecast includes the region under the higher precipitation totals when Reno does not. The more *local* precip forecast shows .84" for Truckee at 6200', .33" for Mt Rose at 7200' and 1.21" for Blue Canyon at 5200'. I think totals around 6'+/- for Truckee/ Tahoe City seems reasonable and 1-1.5' above 7000' for the TSC is also reasonable. With the lack of abundant moisture these snowfall totals should be met because of the cold air involved with the system. Temps above 7000' will be in the 20s so 15:1 or better snow2water ratios are possible. This is great news for deeper snow, but if temps were warmer, the good old Sierra Cement would create a better base for skiing/ riding. 15" of fresh pow on rocks doesn't sound too good for cruising in the backcountry or off piste. 15" of blower on a groomer of man made will be sweet though. Precip should shut off in the wee hours of Saturday with some lingering snow showers along the crest early in the day.

Now for the winds. This storm will pack some serious winds. On Friday, S winds will pick up early in the day, switching SW by afternoon to 25-40 mph, gusting to 60mph in town with ridge winds reaching 125 mph during the brunt of the storm.

Right now it looks as if the Saturday night-> Sunday system will stay North giving us only some light snow showers at best.

Enjoy the storm!

Just the beginning

2009-11-18T07:37:00.000-08:00

11/18/09 7:37am Update 11:00am Update 1pm

Winter Storm Watch issued for Lake Tahoe Basin. Watch out!

Last nights storm fell apart as forecast. Dusting in town to a few inches on the hill. Squaw is calling 2-4" up top, Alpine claims 2". Take your pick.

Ridge builds back in today for fair weather Wed/ Thurs. Friday storm on track to be a major blow event with some snow. My call of a two foot week long total could be in jeopardy, mostly because last night's storm was kinda slack. As of this morning, we are going to be looking at a very windy Friday with precip starting to bank up against the Tahoe Sierra by afternoon. Current H2O forecast shows 1.03" for the West side of Truckee @ 6200', and 1.5" at Blue Canyon @ 5200'. I think with the cold air we should see 18'+ along the crest, 12"+ at 7000' along the West Shore and 6"+/- in Tahoe City but snowfall totals will drop off quickly East of the crest. The storm is fast moving, so if it was to slow down this would change a bit. Expect the main precip event Friday afternoon-> night with most action winding down early Saturday morning.

More to come as we get closer.......

Snowy Week

2009-11-17T07:12:00.000-08:00

11/17/09 7:12am

Winter Weather Advisory for the Western Slope of Northern Sierra Nevada

Snowy week on tap for Tahoe as two storms and some lingering showers will give us the winter feel we have been looking for. Currently a vigorous storm is lashing the PacNW and we will see a piece of that energy split off and drop down the coast. This will give us tonight's snow. Accumulations will be light due to the splitting nature and the shearing apart of that energy as it slides down the Sierra. The bulk of the precip will stay North of Tahoe, giving Lassen and Shasta a good shot of snow.

For us, the associated cold front will pass through this evening/ over night and the TSC should see 4"+/- (maybe 6") and in town/ lake level a few inches at best. The band of precip is pretty narrow and will be quick moving. H2O forecast for the next 24hrs shows .12" for Truckee @ 6200', .05" for Mt Rose @ 7200' and .3" at Blue Canyon @ 5200'. Snow levels will be 5k & lower so we should see all snow out of this one.

Winds have already turned to the SW, hence the warmer temps this morning and especially this afternoon. Highs today near 50F in Truckee and 40s @8k. Cold front swings through bringing SW winds 15-25 G35 and ridge winds to 80mph overnight. Temps tomorrow will be low 40s in Truckee and low 30s @8k. Snow showers will last into the day along the crest with some accumulation.

The bigger story will be the end of the week storm which has the potential to be the season starter. Models over the last day have shown the timing being later on Friday/ Friday night rather than Thursday night. Where the jet stream sets up remains to be the big question. Placement means 1-1.5" H2O, or 2"+ H2O. More likely than not, we will see 1.5-1.75" H2O along the TSC, and with temps staying in the 20s, we could see snow to water ratios 15:1 or even 20:1. So questions still abound. Still sitting with my projection that by Saturday we could see a weekly storm total of around 2', maybe more. Snow showers should last through Saturday and even into Sunday along the crest. More to come to fine tune this.

Could this be the beginning?

2009-11-15T07:27:00.000-08:00

11/15/09 7:27am
Lots to talk about this morning. This week could possibly hold the season beginning storms we have been looking for.

The past couple of days have seen the coolest temps yet this fall which has allowed for snowmaking by local resorts. Hard to talk about snowmaking while looking at pictures from Mt Baker in WA or Whistler in BC with waist deep turns on their opening days. But hold on to your boots, we might just get what we are jonesin for.

Today, Sunday will be a fair day, maintaining the cool temps due to the inversions that have set up over the last 12hrs. High pressure setting up overhead has trapped the cool air in the valleys, couple that with the Easterly flow, temps will not rise all that much, although a bit warmer than yesterday. Should see highs in the mid 40s today. Tomorrow the ridge starts to slide East in response to the strong low dropping out of the GoAK. Winds will switch to a SW direction tomorrow which will allow temps to rise into the 50s. Balmy. High clouds will also increase on Tuesday and by Tuesday night we should see some light snow showers with snow levels around 5500'. This first bit of energy is not impressive at all, but what it is doing is setting the stage, "priming the pump" for what's next. As of this morning, the forecast is looking good for a main event on Thursday night->Friday. HPC H2O 5-day precip forecast shows a 2.5" bullseye just West of the TSC. Snow levels for this second storm look to be ~5000'. We are 4 days out, so there is still time for things to change, but first call is about 2', maybe more along the TSC by Saturday. We will see how this shapes up over the next few days. Things can change for the better, but also we could get the good ol' Sierra Stiff Arm (SSA). You will sure hear the talk around town.

More to come......

Tracking East

2009-11-13T07:09:00.000-08:00

11/13/09 7:09am
I waited until this morning to see what would be happening with this afternoon/ tonight's system. Last night it looked like there would be two possible tracks, one coming down the Northern Sierra Nevada or one with the low dropping into Northern Nevada/ Great Basin. Well, the Easterly track won. The cold GofAK low will drop through OR/ ID into N. Nevada and then speed off to the East via the Great Basin. What this means for Tahoe is a chance of snow showers (a dusting max accumulation) this afternoon/ tonight and the onset of the coldest temps we have seen thus far this fall/winter season. The plus side of this is that the resorts will have temps cold enough to unleash the snow guns through the weekend.

For Truckee/ Tahoe daytime highs will be in the upper 30s, 20s @ 8k and nighttime lows will be it the teens @ the lake and single digits in Truckee. Skies will be partly cloudy and there will be some gusty SW winds to 50mph today along the ridges, switching N-NE-E on Saturday and increasing to 55mph+.

High pressure rebuilds quickly on Sunday which will bring temps back to the upper 40s for Mon/Tues.

Looking to Wed/ Thurs is when we see our next chance for precip. I have said *major* storm in past posts but we might do better calling it a decent storm. Current forecast show two shots of energy, one Wed night and another Thursday afternoon/ night. Snow levels will generally be 6000' or lower, but will fluctuate between shortwaves. More to come as we get closer.

Take it

2009-11-12T07:39:00.000-08:00

11/12/09 7:39am
Cold front blew through as forecast last night leaving a blanket of white. Not the late Michael's kid, but really our first snow of the season. Accumulations are about 4-6" on the crest and 2-3" in town.

Looks like Friday/ Sat system back in the cards as well as our coldest temps of the new winter season are set for us this weekend. Models differ on precip amounts, so check back for an update later today. Still looking for a *major* snow late next week. Stay tuned....

11/11/09 7am
No major changes to the forecast from yesterday afternoon. HPC shows things a little drier, so don't be pissed if there is 4"+/- up top and only a dusting in town. Friday night->Sat storm might be back in the cards. Again this would only be light accumulations. Currently- no season starter storm lurking.

Winter Weather Advisory still posted for the Western Slope of the Northern Sierra Nevada.

The Word

2009-11-10T16:00:00.000-08:00

11/10/09 4pm
The word this afternoon is trending a bit drier, but all in all no surprises in the afternoon forecast package for tomorrow. Winds have started to pick up this afternoon, and the high cloud cover has been persistent all day. High temps this afternoon are around 50F.

Looking at tomorrow and Thursday's storm, a Winter Weather Advisory has been hoisted by the Sacto NWS for the Western Slopes of the Northern Sierra Nevada. For Tahoe, precip should start banking up against the crest in the afternoon and dropping into the basin by evening. Snow levels will start out around 7k+/- and drop quickly with frontal passage. Cold front passage is approximated to be around 1am Thursday morning, so this will essentially be the *height* of the storm. How high? About high enough to drop 3-6" along the TSC and 2"+/- around Truckee. So nothing big in the accumulation department. Temps will drop pretty good behind the front as Thursday's highs will be ~40F in Truckee and upper 20s @8k. Winds will be strong during this event, SW 15-25, G40+ in town and gusts exceeding 75mph along the ridges in the afternoon, decreasing substantially after FROPA. Snow showers will linger on Thursday, mostly along the crest. Morning lows Friday/Sat/Sun will be in the mid teens with afternoon highs in the 40s.

This storm is definitely on the cold side for Tahoe in mid November, so the snow will be light and powdery.

Not so good news for the potential storm for Friday/ Saturday. Models are making it all but non existent, so we will see if they come back around in the next 36hrs or so. Right now the consensus is rising heights and dry conditions Sat->Tuesday.

The first significant snow producer for Tahoe might be next Wednesday.

Colder temps and light snow coming

2009-11-10T07:13:00.000-08:00

11/10/09 7:13am
Prognosis is good. Snow will return to Tahoe. Current thinking is the slower solution, but not as much moisture as we had hoped. HPC H2O guidance shows ~.25" for Truckee by end of day Thursday, and close to .5" along the Tahoe Sierra Crest. This equates out to about 3" in town and up to 6" along the Crest. Temps will be in the low 20s @ 10k, so the snow will be a light, powdery variety, not the Sierra slop. Snow levels will start out @7k+/- and drop to below lake level, possibly down to Reno by Thursday morning. Timing looks to be Wednesday afternoon/evening for the beginning and action should taper mid-day Thursday, hanging on longer along the TSC. Temps will be in the upper 30s in Truckee by Thursday, 20s @ 8k. The system possibly for Friday/ Saturday is in question.

There will be another update when this afternoon's forecast package comes out. Might be time to put the snow tires on the ride.

The hype is deafening. I am not going to make any calls on the precip chances for later in the week right now. I will talk about certainties. What is certain is that it will get windy, it will get colder and we will see snowflakes in Tahoe.

The Uncertainties.......

The model solutions for later this week hold little to no confidence. The track of the GoAK low is not known, and could take a quick, tight path close to the coast which will give us *light* snow on Wednesday night/ Thursday. The low could also take a slower, more seaworthy track (possibly closing off) which would allow to more moisture to become entrained in the system, and push the time frame back to more of a Thursday time frame. By all means, this is what we want. We want slow and out to sea. If the low takes the right trajectory, we could see pretty decent snow accumulations along the Tahoe Sierra Crest, although at this point I doubt that this one storm will be the season starter. Alas, some models show another storm possibly Friday night/ Saturday, and a series of storms later next week.

We all need to keep our excitement in check here. It is going to happen, just won't be able to turn it around in one storm. Temps will be cold, so snowmaking will happen. I am as excited as anyone (chub factor 4 out of 5). We need a bit more time to make sure that the tease factor is limited and we can see this coming stormy period for what it is, not what we want it to be.

Update tomorrow......

Sitting, Waiting....

2009-11-08T08:01:00.000-08:00

11/8/09 8:01am
Sitting and waiting here on a chilly Sunday morning. Temps bottomed out at 15F here in East Truckee this morning with a cool frost on all the trees, roofs, grass etc. The low sun angle of the early morning makes it look like winter. The only problem is that today should see a high temps of 50F, which is not so winter like.

The Teaser

Today's look at the forecast is pretty much the same teaser that we have had for a few weeks now. If the forecast from last Sunday played out for this past week, we might be squeaking out a few light footed turns in the backcountry or sliding some rails at Boreal. Problem is the jet stayed North and gave OR and WA a good shot of moisture. Mt Baker in WA has received over 2' in 3 days, Mt Bachelor in OR has received about a foot, and Mt Hood is ready to open this week with a settled snow dept of 30" @ mid mountain.

Back to Tahoe. If I were to base this week's forecast off today's 06zGFS, we would be gearing up. This model run shows a good shot of precip starting Wednesday night as a low drops down from the GoAK, with a reinforcing shot both Friday and Saturday. If this holds true, we could be in business. But this run is an outlier, as all the other models reach no consensus and are completely out of sync with each other. So basically, the forecast lacks confidence outside of 48hrs.

For Sunday-> Tuesday, high temps in the upper 40s/ low 50s in Truckee and upper 30s @8k. We will see some weak energy brush us by to the North again on Monday night, so a slight chance for a shower exists Monday night/ Tuesday morning. Another narrow band of moisture could produce a shower on Wednesday. Nighttime lows should be in the 20s in Truckee.

Looking beyond Thursday is any one's bet. Some models show more of the same, with the jet staying North into the PacNW. If the 06z becomes the big winner, late this week/ next weekend could be our first large snow producer. Regardless, it looks as if temps will drop a bit later this week so snow making efforts will be underway. Farther down the line, long term forecasters still foresee a large scale pattern shift due to the MJO and its effects on GWO (Global Wind Oscillation) which should amplify the pattern, with high pressure retrograding out to 150W and the storm door to open like the red carpet for the Oscars. The timing on this would be around 11/18 +/-. Stay tuned......

UPDATE for Today

2009-11-06T11:06:00.000-08:00

11/6/09 11:06am UPDATE
Showers starting to develop over the Tahoe Sierra Crest this morning. I guess the dynamics associated with last night's weak system want to hang around for a while longer than previously thought. Snow levels are currently around 8k, as it is 34F @ High Camp @ Squaw, and 28F @ the top of Mt. Rose. Web cams show rain @ High Camp with snow on Siberia ridge, at Relay Peak on Mt Rose looks to be partly sunny. I am in East Truckee and the sun is out. Clouds are mainly hanging onto the highest elevations.

From 8:19am
Current weather systems streaming North of Tahoe, but the swell is right on. High Surf Advisory has been issued for most of the NorCal coast. Swell heights are running 17-19ft @ 17sec with breaking surf of ~20ft+/ for tonight through Sunday. The swell has been generated and focused on NorCal due to the strong low pressure situated in the GoAK. Jet stream is running along 40N into the West Coast, just North of Tahoe. This can be seen very well in the 28km WV loop.

Basically our weather systems are brushing by to our North by a few hundred miles. This leaves us with breezy conditions and cool temps. Today, highs in the 50s with winds gusting to 30mph, 50mph on the ridges. Cooler temps arrive tomorrow and through the weekend with high temps in the 40s. Should be mostly sunny/ breezy through Sunday afternoon. Lassen and Shasta have been and will continue to see light precip, but nothing of substance. In Tahoe, looks like we will be dry through to the middle of next week, when the forecast holds little confidence as to what will happen. Been a lot of talk on the interwebs as to a stormy period hitting Tahoe in mid/late Nov with abundant precip and cold temps. Fingers crossed.

No snow, Go Surfing

2009-11-06T08:19:00.000-08:00

Warm, Windy-> Cooler, Windy, Showers

2009-11-05T07:00:00.000-08:00

11/5/09 7am
Headline sums it up. Current system splitting off the coast and moving into Oregon and the other half shooting down the West Coast towards Baja. Winds have increased along the crest to the 50mph range, and will continue to increase as the day progresses. Expect ridge winds to top out somewhere around 80mph tonight. This system will bring little more than clouds and wind. Bulk of moisture and dynamics are staying to our North, so we get the scraps of the tail end. There will be light showers tonight, with snow levels ~7500' +/-. Total QPF not more than .25" @ best. The good thing is that this first system is pushing the high pressure ridge East, which is essentially opening the door for what's next to come.

What's next to come? A whole lot of "would be great if the jet stream was a bit more South." Saturday will feature the next shot of energy to hit the West Coast, although cooler, there is less moisture and once again the bulk of the energy will be kept in OR. Saturday's storm isn't really anything. This weekend will be cooler, breezy and feature partly cloudy to mostly cloudy skies at times.

What's after Saturday? Maybe a system on Tuesday after a cooler Sunday/Monday. Confidence is low for early next week, so just enjoy the fall like weather over the next few days. There are a few resorts open in CA for your riding enjoyment. Boreal, Mt Rose, Mammoth (which will probably be open from the top on au natural, man made down low) Snow Summit and Bear in SoCal all have something to offer.

FYI- The word is that El Nino is gaining strength like the Guvinator on steroids. Good things to come??????

Fizzle

2009-11-04T10:52:00.000-08:00

11/4/09 10:53am
Today will be much like yesterday, plus a bit more of a breeze and temps a few degrees cooler.

Looking at the potential storms to effect Tahoe over the next few days, not good news coming from the models. As for Thursday's system, looking more like a classic "more blow than snow" scenario. Winds will increase later Wednesday and especially Thursday and will pretty much stay breezy through the weekend. The ridges of course will see the highest winds, around 75mph by Thursday night, backing down into the 50mph range by Friday and into the weekend. Notice I haven't mentioned precip/ snow yet. Well there is a reason for that. Don't get excited because you will only be let down. Current HPC QPF for the Tahoe Sierra Crest is maybe .25". So for Thursday night, a splitting system, the bulk of the energy is going to the PacNW and the other shot going towards Baja, we will get little moisture, wimpy dynamics and all around a weak system. Snow levels for Thursday night-> Friday system look to stay ~7500' +/-. Nothing substantial regardless. Friday will feature the chance for showers and wind & clouds.

Saturday's system I mentioned in the last post looks now to be all but non-existent. Models have trended all energy North of Tahoe leaving us with a few showers at best and warmer temps. Things could revert back to how we saw it yesterday, but not to sure about that. There is a large amount of uncertainty regarding this weekend's precip chances. Best chance for some measurable precip might be next Tuesday? With the massive amount of uncertainty with the forecast, I cannot settle on a definite forecast moving forward. The main take away is cooler, unsettled weather with a chance of showers/ snow at higher elevations.

Temps will slowly drop over the next few days, but not as cold as we thought yesterday. Expect temps to slide through the 50s into the 40s in Truckee by Saturday, and mid 30s @ 8k.

More later. Mammoth opens again this weekend. Boreal, Mt. Rose, Snow Summit and Bear in SoCal have some man made for your sliding action.

Cool, Wet Weekend....maybe?

2009-11-03T10:32:00.000-08:00

11/3/09 10:32am
Warm one out there today with a forecast high of 69F in Truckee. Feels not so much like November. But alas a pattern change is on the way, although it won't be the kick off to the ski season.

The models are showing a quicker time frame for this weekend's weather. Currently high pressure situated at the dateline will shift East over the next few days. By Thursday it will be around 160-150W, which is perfect for wet weather in Tahoe. The ridge should stay there for 24-36hrs before a continuation of its eastern progression, which will eventually put the ridge back over the Central West Coast by Monday. For the time frames of Thursday night and again on Saturday, we should see organized precip in the region, but low QPF. Right now we are looking at about .5" H2O on the Western side of the crest. Not a lot, and we will be on the Southern edge of the jet, so snow levels will remain fairly high.

So, for today and Wednesday, sunny and warm. Nuff said. Thursday will feature increasing clouds and winds (possibly strong winds) and precip by evening. Snow levels on Thursday night will start out ~8k and drop after the cold front. Saturday's precip *should* be more of a snow variety but there is still low confidence in the forecast. Expect temps in the low 40s in Truckee this weekend, with low 30s @ 8k.

More to come as we get closer.

Can I get a pattern change?

2009-11-02T17:00:00.000-08:00

11/2/09 5pm
Plain and simple the weather is just too nice. I love Tahoe for the 300+days of sun, but let's get some clouds up in this b^t$#!

Current forecast discussions and model forecasts show a breaking down of the ridge later this week/ Friday with some precip for the weekend. System right now looks to come in warm with snow levels 7500'+, but cooling through the weekend so maybe some light snow at lake level by Sunday. No huge amounts of precip coming, but anything is better than sunny & warm. As we get closer I will bring the low down. For now, enjoy the heat. Forecast high in Truckee for Tuesday is 69F.

Bigger picture- El Nino seems to be strengthening in a robust fashion in the Pacific, the CPC has above normal precip slated for CA the three months NDJ, and we are just due for a good winter. Rally caps on, wash the car, wash the kids, plan some flowers, burn something other than the forest. Time to get things rolling.

600 Miles

2009-10-28T17:47:00.000-07:00

10/28/09 5:47 pm
What a difference 600 miles would make. 600 miles is the distance we missed out on what will now be two rounds of cold, moisture laden cold fronts that are bringing substantial snows to WA,OR,WY,UT & CO. If the ridge of high pressure was forming, strengthening 600 miles more West, the jet stream would have steered all this energy into CA. We would be skiing & riding for sure, on au natural. But alas, 600 miles too far East and we are sitting with snow showers and soon to be warming temps.

For the next few days and into next week, high pressure will dominate our weather pattern bringing mostly sunny to partly cloudy at times skies, temps getting back to seasonal normals and a pretty strong inversion. Temps at mountain tops over the next few days will rise more dramatically than the valleys. Expect highs getting back to the 50s & 60s in Truckee/ North Tahoe over the weekend as temps at 8k get back into the 50s. Morning lows in the 20s in Truckee/ 30s at 8k.

Thursday morning's forecasted low temp in Truckee is 7F. That's chilly. Bundle up or find someone you like to sleep with.

Next chance for weather is Nov 8ish. We will see how that pans out. Keep it sleazy.

2009-10-25T18:37:00.000-07:00

10/25/09 6:37 pm
Forecast is still on track for a major cold front to blow through the region Monday night into Tuesday. Big headlines are lots-o-wind and dropping temps. Monday will be fairly nice with highs in the 50s, but by Monday afternoon/ evening it will become downright windy in Tahoe. Ridge winds to 90mph, and gusts in town to 40mph. There is the possibility of snow/snow showers Monday night, Tuesday and even Wednesday morning South of Lake Tahoe in the Eastern Sierra. Current models show the low trending a bit further West, so more moisture will be available as the front passes through. A dusting at 6k, and a few inches up top seems to be the call. The conditions are right, so with a bit more moisture we will see those snowfall totals climb a bit more. I am not seeing anything substantial right now, but we'll see what tomorrow's guidance has. Temperatures for Tuesday/Wednesday/Thursday will struggle to make it out of the low 40s in Truckee, upper 20s @ 8k. Low temps will be in the 20s.

As for the potential storm for this weekend.......not good news. Yesterday's model runs looked to be telling the tale we all want. Today, natasomuch. The jury is still out for this weekend. I am still holding onto some sort of precip event, although it doesn't look to be the season opener we might well have gotten. Regardless of what does happen, it will be cold enough this week for the snowguns to run. We will get some natural snow. Thursday and Friday look to be warm, and the weekend is still a toss up.

Rally Caps On! Bet On The Wildcard

2009-10-24T08:20:00.000-07:00

10/24/09 8:20am
Piggy backing on my post from yesterday, it seems that the wildcard might have its rally cap on. I mentioned the 10/22 18z & 10/23 12z runs were outliers in showing a follow up cold front later next week that was cold and moist. Yesterday even the NWS Reno guys called these model runs "slop." Well, today, all GFS runs have come around for what could become a progressive pattern for CA. Today's 00z run is the most bullish with a series of storms coming to CA through the next 14days, starting the 29th/30th. We are still a few days out, but now that NWS Reno has started to adjust their long term forecast, and the models coming into somewhat better agreement, we will have to wait and see what happens. It could be the beginning.

The forecast for this weekend is still warm, sunny/ partly cloudy with some afternoon breezes. Expect above normal temps through Monday. On Tuesday the inside slider dropping in from the PacNW will drop temps below normal (down right chilly). Limited moisture Monday night and Tuesday will provide snow showers to the region. Winds will be persistent through the early half of the week.

Past Wednesday confidence is low but gaining in a possible series of colder, moist storms for the Sierra. Stay tuned............

Warm Weekend Then Cold Blast

2009-10-23T10:00:00.000-07:00

10/23/09 10am
Pretty spectacular weekend setting up for Tahoe. High pressure will dominate producing a slight N-NE surface gradient which will keep a slight breeze going. High temps in the 60s, a few high clouds but mostly sunny. Morning lows not even that cold, just below freezing. With little snow cover and aspen trees showing their last flash of color it is a great time for a hike or bike. Mountain biking is all time still, as the lower sun angle has yet to dry out the trails from last/ this weeks' rain and snow. Get out and enjoy because things are going to change Monday.

A lot of Pacific energy is poised to slam into BC and the PacNW over the next few days. Tahoe will see the effects of the tail end of the cold front, but those effect will be felt for sure. We won't see much in the way of precip, but we will get wind and much colder temps than we have had. Monday winds will increase from the West as a cold front drops down the West Coast. By Tuesday low pressure will set up over the Great Basin. Monday night and Tuesday Tahoe will most likely see a few snow showers, but with no significant moisture for us, accumulations will be non-existent to light. Behind the cold front temps will take a digger. Highs in the 60s this weekend will drop to the 50s on Monday and then into the low 40s on Tuesday/ Wednesday. At 8k highs in the 50s this weekend will top out in the low/mid 30s by Wednesday. It will stay breezy at all elevations Monday/ Tuesday/ Wednesday. The cold temps will allow for a shot at snowmaking for a lot of local resorts. If you are looking for the real stuff, head East to UT/WY/CO. Those regions will see good dumps of the frozen white. Of note, morning lows Wed/ Thurs will be in the low 20s & teens in Truckee.

Past Wednesday it looks as if the PNA will turn positive meaning more sun and warm temps for the Sierra. Although yesterday's 18z and today's 12z GFS show a strong cold front and lots of moisture headed our direction on/around 10/30. The problem with this fantasy scenario is that these two model runs are considered outliers. Let's go wildcard! The chances of warm calm weather far outweigh the possibility of a storm to wind out Oct and usher in Nov.

I'll keep my eyes on it.

Waiting....

2009-10-21T17:44:00.000-07:00

10/21/09 5:44pm
Perfect fall weather hanging on as we sit waiting for the first real dump in the Tahoe Basin. There is a lot of energy out in the Pacific, and the remnants of Typhoon Lupit will become extra tropical, although the PacJet will steer all of this into BC and the PacNW. Basically expect the warm, sunny (partly cloudy at times) conditions to continue through the weekend. Our weather will turn much colder, with a small chance of light precip Monday night, as we head into Tuesday of next week as a strong trough establishes itself over the inter-mountain West. This will provide a N-NE flow for us which will bring the backdoor cold front. Details of how cold it will get still need to be worked out, but high temps in the 60s through the weekend will be replaced by high temps in the upper 40s by Tuesday in Truckee.

Enjoy this weekend. The colors are great and everything is still accessible.

Mellow

2009-10-20T16:40:00.000-07:00

10/20/09 4:40pm
High pressure building into the region as yesterday's energy shifts East away from the Sierra. For the rest of the week and into the weekend high pressure will dominate with slightly above normal temps. Dry and warm is the call with high temps ~mid 60s in Truckee, mid 50s @ 8k, and morning lows around freezing, upper 30s @8k due to the intensifying inversion and light winds. The inversion will not get too strong due to energy moving inshore into the PacNW which will bring some breeze to Tahoe and some high clouds over the next few days.

Longer range, questions arise after the weekend as to what will happen to Typhoon Lupit in the Western Pacific. There is a slight chance of the moisture and energy becoming extra tropical, which could get caught up in the PacJet bringing the West Coast of the USA another shot of heavy precip. Time will tell......

Enjoy the perfect fall weather, fall colors and all time mountain biking around the Tahoe Basin.

Snow Showers Today

2009-10-19T08:21:00.000-07:00

10/19/09 8:21am
Cold front passage with some good dynamics will squeeze out some rain and snow showers today. Expect a few inches at best along the ridges and at pass level. Snow levels will remain ~7k or higher. Temps today are some 10-15F colder, so highs will be in the low 50s. Winds will be strong on the ridges and breezy in town today. Ridging starts to rebuild over the region tomorrow for fair weather and warmer temps in the 60s for the rest of the week. Next chance for some precip looks to be just at the end or after the weekend. Enjoy!
