Bogies on the radar

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.

It's Good Out There

Lake Tahoe Area Weather and Snowpack Information

2/7/10 8:52pm

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.

Crab In My Shoemouth

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.
