Lake Tahoe Area Weather and Snowpack Information

3/11/10 6:48pm

Next storm on tap for late Thursday night through Saturday morning. Forecast right now has a Winter Storm Warning for the Western Slope of the Northern Sierra and a Winter Weather Advisory for Tahoe. Typical Sierra storm, starting off strong, wet and warm and ending with low snow levels and a nice topper. Expect rain to 6500' for a time Friday before the cold front drops it like it's hot. 1'-1.5' expected along the TSC. 3-6" Tahoe City/ Truckee way. SW winds will be heavy Friday with ridge winds will hit 100mph easy. Heaviest snow times out to be overnight Friday-Saturday. H2O forecast tallies close to 1.5" along the Western Crest of the Tahoe Basin. So the forecast from yesterday still looks good, but there is one thing to add. By Saturday the wind direction will switch N and eventually NE-E. By the time this happens the strong winds will subside, but a wind scouring event will happen on N-NE-E aspects along the crest. There is also a chance that this system will be quick enough to shift East which will make Saturday a possible blue-bird pow day. I think it is safer to say that the sun will be out along the crest by afternoon. Kinda sucks seeing how this is going to be the last shot of decent snow for at least a week. Possibly longer.

Starting Sunday skies will be clear and a warm ridge city sets up. Really warm ridge city. 60F in Truckee Tuesday? Yep. Spring arrives Sunday. Just with the time change. Remember to set your clocks ahead Saturday night. Riding on Sunday comes around an hour earlier.

By Tuesday a full on corn cycle should develop on South facing aspects. Due to the high pressure overhead temps might not drop below freezing Wed/Thurs @ elevation. Be mindful of the first big warm up and how the snowpack will react. There will be an avalanche cycle Friday night/ Saturday morning as this heavy new snow will sit on the dry, powdery snow from Tuesday night (on N->E aspects where the cold snow lasted these last two days). As it gets warmer on Tuesday/ Wednesday wet slab avalanches are possible due to intense solar radiation. Get out early to avoid the risk. Afternoon's will be sunny and warm. Great for beer drinkin.

The last few days of March could bring one last breakthrough of the Westerlies. This is good news for snow lovers.

Lake Tahoe Area Weather and Snowpack Information

3/10/10 8:35pm

The good word is that snow quality was A+ today. Tomorrow the snow will change a bit as warm temps and increasing humidities manktify the lower elevations. Overall Thursday will be a great day to ski/ride nonetheless. If you can get out, do so. It will be sweet.

Next storm on tap for late Thursday night through Saturday morning. Forecast right now has a winter storm watch for the Western Slope of the Northern Sierra and snow advisories (maybe the WSW?) for Tahoe? Typical Sierra storm, starting off strong, wet and warm and ending with low snow levels and a nice topper. Expect rain to 6500' for a time Friday before the cold front drops it like it's hot. 1'+ possible along the TSC. 3-6" Tahoe City/ Truckee way. SW winds will be heavy Thursday night into Friday with ridge winds 100mph easy. Heaviest snow times out (right now) to overnight Friday-Saturday. H2O forecast tallies close to 1.5" along the Western Crest of the Tahoe Basin. More to come tomorrow as we get one last storm and then ridge city. Warm ridge city. Really warm ridge city. 60F in Truckee Tuesday? Say it ain't so.

Temps Thursday will top out in the 40s in Truckee, upper 30s @ 8k. Temps start to jump Sunday.

Lake Tahoe Area Weather and Snowpack Information

3/9/10 6:59pm

Fresh snow for Wednesday along the crest. 6"+/- of cold, dry, blower pow. The cold goodness of March. Get it while you can, because it will get warm soon. Don't even want to talk about next week's balmy temps. Forget about it. Go ski/ ride Wednesday. It's going to be good and cold. High temps in the 20s @ elevation and breezy. Cold smoke under your feet. Nuff said. Enjoy!

Lake Tahoe Area Weather and Snowpack Information

3/8/10 8:58pm

Big news for Tuesday/ Wednesday will be the cold temps. Nighttime lows near 10F, and daytime highs topping out in the low 30s in Truckee, 20s @ elevation. Winds will be breezy at times as a few weak impulses bring chances of precip to the Sierra. Tonight a few inches of new snow are possible in areas where scattered showers deliver. Tuesday will feature clouds and sun turning mostly cloudy with snow developing in the late afternoon/ evening. Ridge winds will get back to 70+mph from the W-SW Tuesday night. Wednesday will be cold with a slight chance of light snow. Total accumulations by Wednesday night along the Tahoe Sierra Crest won't get much better than 6-8".

Moderating temps late in the week. Possible chance for precip/ higher elevation snow Friday night-> Saturday. Next week looks spring like with temps in the mid 50s in Truckee. It will sure feel different after the time change Saturday and warm temps a few days later. The end of March is on track to bring another shot of winter. Spring is not far away......

Great weekend, snow on the way

2010-03-07T19:30:00.000-08:00

Lake Tahoe Area Weather and Snowpack Information

3/7/10 7:30pm

Blue bird morning giving way to some snow showers later in the day today. Great day to be outdoors as temps rose well into the mid 40s, 30s @8k. Winds were calm most of today but have since switched SW and are picking up steam. Strong cold front should pass through the region Monday as an outside slider drops along the coast. Expect colder temps and snow tomorrow with SW winds gusting to 60+mph along the ridges. Accumulations along the TSC have a good chance of reaching 4-6". There is more snow possible Tuesday. Overall skies will be cloudy with some sun away from the crest.

There is more snow possible Friday night-> Saturday, with the potential for moderate snowfall. Skiing and riding have been great all week and we are going to see a nice topper freshen things up over the next few days.

Cold temps Monday->Tuesday will keep the snow in great condition. Temps in Truckee will stay in the 30s until Wednesday as we will see a 10F+ jump in temps on Thursday to near 50F. 20s @ 8k warming into the 30s late in the week.

Tahoe will see another fine week of skiing/ riding with fresh snow, cold temps and then clearing mid week. Enjoy!

Mid Week Delight

2010-03-03T07:42:00.000-08:00

Lake Tahoe Area Weather and Snowpack Information

3/3/10 7:42am

Winter Storm Warning issued for the West Slope of the Northern Sierra Nevada for today and a Winter Weather Advisory has been issued for the Tahoe Basin. H2O forecast for the next 24hrs is ~1.7" for the West side of the crest. Temps are in the teens @ 8k with S-SW winds 40-50mph gusting 65+mph. Expect winds to increase to near 80mph as the cold front passes today. Very cold system will create favorable snow to water ratios of 12:1 and better, so 1.5' of fresh, blower pow along the crest is reasonable. Elevations above 9000' could easily see 2'. At lake level, 3-6" is expected. Snow should taper to showers late tonight.

Thursday will be a great day of skiing so get out and enjoy.

The weekend is not looking as stormy as previously forecast. What was once to be a big storm, might actually turn out to be nothing more than snow showers. Current consensus is that the GulfAK low will cut off and slowly meander down the CA Coast, finally pushing onshore in SoCal. The track of the low is uncertain at this time, which is causing the problems in locking in snowfall amounts. Right now the track looks to be off shore far enough to give coastal CA rain while leaving the Sierra out of the juice. Yes, the Sierra Stiff Arm. Then, we could also see a period of moderate snow Saturday. More to come as we get closer.

Snow today, cold smoke tomorrow

2010-03-02T06:50:00.000-08:00

Lake Tahoe Area Weather and Snowpack Information

3/2/10 6:50am

Cloudy skies this morning and breezy winds along the TSC. Temps in the 20s @ elevation with SW-S winds gusting over 60mph. Bogies on the radar in the Central Valley starting to light up the Western Slope of the Northern Sierra. Only a few inches of snow forecast for today as the main dynamics will hit Shasta. So expect windy conditions and light snow along the crest.

As for Wednesday, the next part of this system, born from the Bering Sea swings into the region dropping snow levels to <4500' and has the potential to drop 1'+ of the blower powder. Very cold storm and favorable snow to water ratios. Temps in Truckee 41F today, 31F tomorrow. Mid 20s @ 8k today, mid teens tomorrow. Ridge winds will stay near 70mph+ for tonight and tomorrow. Total snowfall accumulations will near 2' along the TSC by late Wednesday.

The snow Wednesday/ Thursday will be blower, epic, over the head pure shizzle. Go get some! Call in sick for sure.

More snow Friday night/ Saturday.

Lake Tahoe Area Weather and Snowpack Information

2/28/10 9:50pm

Active pattern to continue this next week as Tahoe should see two storm systems. Dropping from the GofAK, low pressure will bring winds and precip Tuesday and again Wednesday. Tuesday will feature snow levels ~5500' while on Wednesday snow levels drop 1k. The Northern and Central Sierra look to be favored this go around. Still, snowfall totals will be moderate, 1-2' above 7000' with a few inches at lake level. Another round of snow seems probable for Friday-Sunday. This system should be colder than Wednesday, with snow levels ~4500'. Models are showing different solutions for the weekends storm, both in timing and also intensity. On the low end, another 1-2' while the high end would be 3-4' with snow showers tapering Sunday. This next week looks to be good regardless. Still beyond there is a possibility of another system 3/11->3/15. Let's not ge ahead of ourselves.

Today was a good one. High temps in the 40s in Truckee and mid 30s @ 8k. Winds were non existent through most of the day but by 5pm the N-NE breeze picked up and cooled temps off quickly at upper elevations. Mammoth had a different day with temps in the teens @ 10k, and a still N-NE wind gusting to 58mph around 2pm. On Mt Rose @ 2pm there was barely a measurable wind.

Monday will be fair and warm as temps reach 50F in Truckee, 40F @ 8k. Clouds will be on the increase as the day goes. SE winds will switch S and increase as well. Low pressure will bring precip to the Tahoe Basin by midday Tuesday. There will be another colder round on Wednesday. Showers could possibly linger into Thursday as the trough reloads with another system for the weekend. Winds will get quite gusty on Tuesday lasting into Wednesday. Temps in Truckee will drop back into the 30s, 20s @8k.

All of this is subject to revision tomorrow when a completely different scenario is likely.

As for the snow. My best advice is to go as high as you can and stay out of the sun. It is March now and the sun angle is getting higher by the day. Late yesterday and again today intense solar radiation torched the snow. Anything that has seen sun has a breakable crust. Aspects that were sheltered from last night's N-NE breeze and has not seen any sun are skiing great. Unfortunately snow under 7500' was extremely wet on Saturday and has become melt/freeze mank. Tomorrow this lower elevation snow might ski better, but when the goods exist on high elevation N-NE aspects, there is no need to screw around. There is once again great snow to be ridden.

Lake Tahoe Area Weather and Snowpack Information

2/27/10 9:33pm

Fresh snow today was a bit on the heavy side. Temps stayed a bit warmer than the forecast called for which brought the cement to Tahoe. Upside is we'll be skiing it till May. Longevity over powder. Snowfall totals ended up on the low side of the forecast as a result of temps. ~18"+/- along the TSC.

Sunday looks to be sunny with light winds. A few clouds/ high clouds might filter through but the clouds/fog of today will be absent. Temps Sunday into the 40s in Truckee and mid 30s @ 8k. Next storm on Tuesday->Wednesday and again Friday. Next weeks snows should be colder with snow levels <5000'. More to come tomorrow as the storm train should persist for 7-10days with a storm every 3.

Lake Tahoe Area Weather and Snowpack Information

2/25/10 8:56pm

The Skinny: Snow and rain will start mid-day tomorrow and persist through Saturday morning. Today's guidance shows this system trending a little bit warmer and will suffer a bit more split, sending the best moisture and dynamics South of Tahoe. Mammoth and the Southern Sierra will see 3-4' of new snow. Tahoe will see 1-2' above 7000' and 2-3' above 9000' along the Western Crest. Tahoe City and Truckee will see far less due to snow levels starting out ~7000'+. 6" or so for Tahoe City with lesser amounts as one gets below 6000'.

Temps @ 8000' will top out just around freezing with temps near 40F in Truckee. High temps drop 5F for Saturday. Winds will be breezy, S-SW 15-25 with ridge winds 60->90+mph. Gusts on Saturday will be generally <50mph.

This is a typical California storm. Coming in hot and leaving cool. Cement with a blower topper. Have a great weekend!

Up to one foot can be expected at lake level in Tahoe City. Snow showers will linger into the afternoon along the crest. In Truckee 6" or so as it is a bit warmer tonight and snow to water ratios are lacking at the moment. Snow levels should bottom out below 5000' by morning. Wednesday highs near 40F in Truckee, upper 20s @ elevation and breezy.

For Friday, good news as there seems to be less/ no splitting of the system with the low pressure possibly gunning straight at Tahoe. More to come, but as of today we could be looking at 3-4' of new snow along the crest between tonight and Saturday.

The next week of skiing should be sick. Thursday it will get a bit warm, but only for a day. Looking beyond Saturday, Sunday should be dry with another system early next week.

Have fun these next few days. Ski fast and take chances!

Lake Tahoe Area Weather and Snowpack Information

2/22/10 8:09pm

Active weather pattern this week as we are setting our eyes on snow Tuesday-> Wednesday and again Friday-> Saturday. Winter Storm Watch for the West Slope of the Northern Sierra Nevada and a Winter Weather Advisory for Tahoe have been issued for Tuesday night. Snowfall accumulations most likely will be 4-8" @ 6k (8" West Shore) and 8-12" above 7000'. Snow levels should generally stay below 5500' but might rise to 6500' for a period Tuesday evening. Really good moisture tap on this one, so I wouldn't be surprised if precip amounts turn out higher. This doesn't mean that snowfall totals will be higher, if we get a bit too warm the accumulations will suffer. Winds will be SW-W 65mph along the ridges Tuesday night. Avalanche concerns will rise on Wednesday as a nice layer of surface hoar was able to develop last night under clear skies and fresh snow. This layer will now be buried under 4-12" of heavier, denser snow.

After Wednesday, eyes turn to Friday's system. A bit bigger, stronger and more moist, but with splitting tendency. Have to see what happens with this storm, the bulk of the junk might very well end up in SoCal. The 5day H2O forecast from the HPC shows ~4.5" along the Western TSC. Stay tuned........

2010-02-21T18:10:00.000-08:00

Lake Tahoe Area Weather and Snowpack Information

2/21/10 6:10pm

Crazy weather happenings last night and this morning. A cold front stalled just NE of Truckee, from about Lassen to SE of Sparks and produced heavy snowfall in a very narrow band. North Reno/ Sun Valley received 2'+ of fresh pow, Reno downtown got 1'+, while Truckee clocked an amazing 2". Goes back to that old saying, what happens when hell freezes over? Well, if Reno is so close to hell you can see Sparks, I guess now that hell is frozen over I can ski there too.

Snow showers will continue tonight in Tahoe where 4-6" of additional accumulations are possible above 7k. Tomorrow should be a great day of riding, but be aware of the dreaded East wind. That is what we will have tomorrow, E winds gusting 30mph early. Snow showers might pop along the TSC on Monday.

Tuesday's/ Wednesday's system is still on tap, with anywhere from 1-2" of H2O forecast depending on what model you are looking at. Snow levels will start quite high on Tuesday, ~6500'+/- (7k?) but will drop as the cold front passes. So anywhere from 1-2' of new snow by Wednesday night along the crest, but I feel the 2' totals will be farther South, more of the Mammoth area.

Thursday looks dry before another round Friday->Saturday. We might suffer from the torments of split flow for the late week storm, but more clarity is needed before we get into potential snowfall totals.

Have a fun week. The best skiing in the country is right here in Tahoe/ Sierra and is only going to get better.

More dust for your crust

2010-02-20T18:23:00.000-08:00

Lake Tahoe Area Weather and Snowpack Information

2/20/10 6:23pm

Today paints another picture as to what the weather will do. In a nutshell, the GFS is not as bullish about this up coming week's precip chances compared to yesterday, the H2O forecast for the next three days is down but the bright spot is the CPC 6-10 & 8-14 day outlooks show below average temps and above average precip for the Tahoe Sierra. The CPC also shows heavy rain and snow for CA on 2/22&23. Good to see the potential, although there is still uncertainty as to what next week will bring. I don't think we will see realization of my 18-24" call from last post by Tuesday. 1'+/- is more reasonable when factoring the latest guidance. When we get a better picture of Tuesday's/Wednesday's storm, then we might total 18-24" from today as H2O totals will near 2".

Tonight will feature snow showers dropping down from the North as low pressure moves closer to the Central/ Southern CA coastline. Winds are currently SW gusting 30-40mph+ along the ridges. Temps have stayed in the 20s @ 8k, so the snowpack is well frozen at this point after such a warm week. We might see a burst of moderate snow tonight, but the coverage will be isolated. Some portions of North Lake Tahoe will see 4" while others might see 8". Snow showers have been more common along the SW side of Tahoe today, and is currently showing the most returns.

Tonight winds will gust to 50mph from the SW, switching NW and eventually E by early Monday. Expect wind speeds to diminish as Sunday turns to Monday. Highs will be in the 30s in Truckee, 20s @ 8k for the next few days. As it stands right now, snow showers are possible along the TSC each day all week due to favorable orographic flow into the Sierra . A warm up will occur mid week before the possibility of a more powerful storm late next week. Stay tuned, this will be an interesting and active week.

2010-02-19T21:14:00.000-08:00

Lake Tahoe Area Weather and Snowpack Information

2/19/10 9:14pm

The week of dry is coming to an end tonight. Bottom line is the Sierra will receive beneficial snows over the next week. Tonight and Sunday are just a primer as to what will go down next week. OK, potentially go down next week. I'll just start with the best case scenario. Today's 12Z GFS shows an almost continuous precip event starting Monday night/ Tuesday and lasting through the following Sunday/ Monday. All the runs of the GFS are holding strong to this theory. There looks to be some periods of higher snow levels, maybe 7Gs by next Thursday before crashing behind a strong cold front. Unfortunately all forecasting models are not in agreement. We will have to see how this all pans out. PNA is trending negative but be mindful that it also is forecast to go abruptly positive as we march into March.

So this weekend- light precip entering the region tonight from the N-NW as low pressure drives South into SoCal and a shortwave is dropping South out of OR/ID/NW-NV. The system with the moisture is really too far South to give us any real accumulations. Sunday looks to be a better bet as another system makes its way East off the Pacific. Better moisture and dynamics associated with this one as Tahoe could see 4-6" along the Western ridges of the basin. Snow levels should stay @ 5000' this weekend before rising on Tuesday. Tuesday is another bright spot on the horizon as another shortwave rounds the base of the blocking high in the GofAK/ BC coast bringing a potential 1-1.5" of water our way. Right now the HPC 5day H2O forecast shows ~2" along the Tahoe Sierra Crest, aka. the TSC. Making a call of 18-24" of fresh snow along the TSC by Tuesday night is reasonable. Looking beyond Tuesday, next Friday could be a whomper as the hits line up.

Of note, we do have El Nino driving the bus this winter and with the Nino usually comes warmer temps with precip. The reason I mention this is because the CPC 6-10 and 8-14 day outlooks show above average precip as well as above average temps.

So much uncertainty. Looks promising though.

Unsettled conditions to return

2010-02-18T20:53:00.000-08:00

Lake Tahoe Area Weather and Snowpack Information

2/18/10 8:53pm

After a few days of spring, and a dry spell that has lasted way too long, unsettled conditions will return to Tahoe tomorrow. The strong ridge overhead is getting pinched North as energy retrogrades West out of Ida-ho (to Ta-hoe) while low pressure makes its way onshore over central/ southern CA. Models are still all over the place, but I do like what the GFS is throwin out. The GFS is very bullish in bringing Pacific energy onshore into CA, with a more Northerly jet streak, every other day through the next week+.

For tomorrow night into Saturday, the storm that once was looks like it will take a jog into SoCal, leaving Tahoe on the periphery. Snowfall totals will be measured in inches along the TSC. Sunday's storm looks like it might be a producer. Problem is, a forecast outside 24hrs right now runs the risk of being completely off. I want to believe that we will see 1-2' of new snow along the TSC by Monday night.

Temps will fall back into normalcy and snow levels will start out 6500-7000' Friday, dropping to 4500' on Sunday. Expect gusty SW winds by tomorrow night along the ridges.

Winter returns and might stay around for a bit. Spring is a ways off. Remember, the jet stream will shift back North as we get later into winter and if the storms are there, the hose will be on big blue. Wax em up! It's going to get good again.

Lake Tahoe Area Weather and Snowpack Information

2/17/10 10:33am
High pressure still dominant over Tahoe today as another warm day plays out. A tease of spring skiing conditions right now as South facing shots have corn (switching to sloppy wet snow by afternoon) and a wintery mix of all sorts of surface conditions on the Northern shots.

Ridge starts to break down tomorrow as Pacific energy from multiple angles beats it up. Problem is the forecast models are changing within 24hr time spans right now, so as for a solid forecast of what might happen in the next few days is anyone's guess. My best impersonation of a weather guy tells me that Tahoe will see light/ moderate precip Friday->Saturday, and maybe into Sunday. Snow levels will be ~6000' or lower. H2O forecast shows ~.75" over the next five days. 6-10" along the TSC between Friday night and Sunday seems reasonable with the lack of confidence moving forward.

So the weekend is a crap shoot, although it will be cooler and cloudier than the past few days. As for next week, the models used to show a train of storms impacting CA, but now models are divergent and the MJO has fizzled.

I have to wait another day and see if the models come back in line, or NWS Reno/ Sacto can figure out with a better brain what might occur. Regardless, it looks like El Nino is still holding tight to the Southern Pacific Jet as it continues to be aimed at Socal/ Baja. Stay tuned, Winter is not over yet!

Lake Tahoe Area Weather and Snowpack Information

2/14/10 7:58pm

Pretty mellow here in the weather department. High pressure is firmly established over the Sierra. Above average temps and mostly sunny skies will prevail through Friday. We will see high clouds filter through, so it won't be the cleanest of ridges. Of note- Tuesday night might contain some light showers as we get tail whipped by some energy entering the PacNW and a weak backdoor cold front. Temps won't drop all that much, maybe getting back to average for Wednesday. On Tuesday night we could see some snow showers along the TSC with snow levels ~7500'. So yeah, high and dry with temps 5-10F above average. Temps in Truckee will be reaching 50F with 40s @ elevation.

Looking down the road the ridge should break down late in the week/ weekend with a blocking pattern developing in the GofAK by early next week. This should allow the Westerlies to reach CA bringing the storms. Smaller systems Friday night/ Sat/ Sun will primp the pump. Next week is looking interesting with North Pacific storms making their way to Baja/ Cabo? Huh?

Enjoy the sun and fabulous backcountry skiing. Corn on the South, wintery love on the North.

February Thaw

2010-02-10T19:33:00.000-08:00

Lake Tahoe Area Weather and Snowpack Information

2/10/10 7:33pm

Weak systems will brush by Tahoe over the next two days. We might see some flakes on Friday as the best moisture will impact Shasta, Lassen and points North. Ridge city starts Saturday as high pressure looks like it will park itself over CA for the following 7days+. PNA is going to stay positive and the storm track will favor the PacNW and the Eastern half of the U.S. for some time to come. We will have clouds every now and then, and temps will warm to above average for mid Feb. Night time lows will be in the teens in Truckee and upper 20s @8k. By Monday temps at elevation might not drop below freezing for a few days. High temps will be in the upper 40s by Saturday in Truckee and low 40s @ 8k.

The thaw is on. This fair stretch could persist for 7-10days. It's been a good run since December. Conditions are mid winter perfect right now and by Sunday we should enter a corn cycle on Southern aspects with unconsolidated snow/chalky buff on Northerly aspects. Great weather for Presidents week coming up. Enjoy the Spring tease.

Lake Tahoe Area Weather and Snowpack Information

2/8/10 7:57pm

Split flow off the Pacific continues and so does the current trend of light snow every few days. The next 36hrs will feature a low pressure center sliding down the CA coast. Cold air and notsomuch moisture will continue through tomorrow as another 4-6" of new snow along the TSC is possible by tomorrow night. Just enough to keep things fresh. SW winds will not be an issue as they will remain fairly light. Expect another round of light snow Thursday night.

Next few days are going to be good. Get out and enjoy. Warmer temps later in the week will definitely change the snow. Longer range is nothing but uncertain. We may go dry. We might maintain. Who knows.

Consistent light snow over the past few days has left fantastic conditions throughout the Sierra. Since Feb 3 there has been ~19" @ 8k. Mid winter perfect.

Break between systems tomorrow as a low pressure system drops out of the GofAK into the PacNW. On Tuesday said low will move down the CA coast. Exact track tbd, and hence snowfall amounts are uncertain. Right now, we are not looking at anything major, but a clearer picture will emerge tomorrow. Expect snow Tues-> Tuesday night. Shortwave ridging returns Wed/ Thurs as another trough is forecast for Friday. Longer range shows the next chance for significant precipitation on/around 2/18.

Temps will be in the upper 30s in Truckee with low 30s @ 8k to being the week, trending a few degrees warmer late in the week. We'll see if this forecast doesn't change 2-3 times in the next five days.

Lake Tahoe Area Weather and Snowpack Information

2/5/10 7:49pm

Interesting times as the forecast seems to change every 24hrs. Bright side of this is the changes are for the better. In the short term, snow showers tonight and Saturday will add up to 6"+/- along the TSC, the West Shore will fair the best for places below 7g's as Truckee and points East see only light accumulations. Nothing huge, but fresh snow nonetheless. Conditions are midwinter perfect right now, and are only going to get better.

Points South of Tahoe, mainly from Mammoth->Southern Sierra will see decent snows over the next two days. 1' around Mammoth and 2-3' in the High Sierra. QPF down there over the next three days tallies about 3".

For Tahoe, temps in the 20s will be the norm @ 8k with clouds and snow showers for pretty much the next 7-10 days. Winds are from the South tonight and Saturday before diminishing and tracking to the North by Sunday. Forecast for the longer term is looking quite good as a split flow pattern develops off the Eastern Pacific and a blocking pattern sets up over the midwest resulting in systems continually impacting the region. The Pacjet will stay focused on SoCal in true El Nino style, so we sill stay along the Northern edge as the bulk of the moisture stays with the jet stream. Snow levels look to stay 5000' and lower. Timing looks to have storms hitting on Monday night-> Tuesday and again Wednesday night-> Thursday. These shots of energy don't look overly impressive, but fresh snow every couple days is great for good riding and a stable snowpack. There doesn't seem to be any sunny days in the forecast.

Enjoy.

Double Barreled

2010-02-04T20:30:00.000-08:00

Lake Tahoe Area Weather and Snowpack Information

2/4/10 8:30pm

Tonight I am liking what I am seeing. After a day or two of downplaying, double barreled low pressure systems in the Eastern Pacific are progressing East and gaining strength. Current H2O forecast between tonight and Saturday is ~2.5" along the TSC, falling off pretty quick East of the crest. Winds are W-SW gusting to 89mph currently along the Tahoe Crest. Heaviest wind are currently in Yosemite high country @ 102mph East of Saddlebag Lake. Wind gusts are forecast to maintain velocity switching S-SW through Friday, slowly diminishing Friday night into Saturday. Overall snowfall accumulations in the Tahoe Basin will be 1-2' above 7k, with 6" or so along the West Shore and 2-6" in Truckee by Saturday night. There is a chance we might see greater accumulations if snow levels don't get as high as currently forecast resulting in more favorable snow-2-water ratios. Current consensus is 6k dropping to 4500'.

We are setting up for another really good weekend of skiing riding with fresh snow and cold temps. Both Friday and Saturday morning should feature storm day conditions with snow showers tapering by later in the day Saturday-> Sunday. Temps will stay in the mid 30s in Truckee and mid 20s @8k.

Enjoy.

Lake Tahoe Area Weather and Snowpack Information

2/3/10 9:34pm
Active pattern setting up for Tahoe. Current forecast looking good for snow to develop Thursday night-> Friday and again on Saturday. I am going to wait until tomorrow night to get into the details because the forecast is still evolving. First call is about 2'+/- along the TSC as the H2O forecast is tallying to 2.5"+ for the 5day. Snow levels will rise to about 6k on Friday, so snow-2-water ratios will be low, but by Saturday snow levels will drop below 5k bringing the blower. Get the boards waxed because this will be the last decent snow event until mid month. Unfortunately next week isn't going to pan out the way I have been talking, and the way that the models were showing 7days ago. By next week there will be a blocking pattern over the PacNW, which will mean either no snow for us, or a colder, showery pattern with no major accumulations. More on that later. So check back tomorrow as the forecast will be fine tuned and I will have the skinny on this weekend's snow.

Of note, there were three significant avalanches on the East Side in the last week. A large, natural slide outside Big Pine which ran about 3000' and a snowboarder triggered slide in the area of the Four Gables which took him for a good ride. Great to hear that the snowboarder is alive and well. Also, an inbounds avy grabbed a ski patroller at Mammoth recently which resulted in injuries. Just goes to prove that the East Side is a much different beast than Tahoe and correlations on snow conditions and snowpack stability are not a given. Be mindful of this. Avy forecast links are below for Tahoe and the East Side.

More tomorrow.

What about Phil?

2010-02-01T20:07:00.000-08:00

2/1/10 8:07pm
Will Phil see himself tomorrow? My bets are on 6 more weeks, but we will see tomorrow morning. Outside of PA, Tahoe is more interesting.

Splitting system impacting CA this evening delivering little more than a few snow showers. Anywhere from nothing to 3" possible tonight along the crest and again Tues-Wed as another weak piece of energy will move ashore. Overall <.5" of H2O forecast for the West Crest of Tahoe over the next two days. Tuesday will have a breeze and a whole lot-o-clouds. Winds will be from the S-SW, and temps will be near 40F in Truckee, 30F @8k. Later in the week into the weekend we should see some better chances of decent snows. H2O forecast shows ~2" of precip Thursday night through Saturday. The GFS shows snow levels staying @ or below 6k through the event. Of course there is uncertainty as to what will eventually transpire but decent snow accumulations should occur above 7g's. Past this weekend the storm door seems to stay open with energy effecting the Sierra every couple days next week. Right now no whompers, just shortwaves every couple of days. More to come as we get closer. Regardless skiing/ riding is excellent right now, although there is a little crust down low.
