Spring storms are spanning across the North American continent right now. Two large storm systems will affect both coasts over the weekend, one will bring heavy, wet snow to many Western resorts and the other will bring rain to New England. Read OpenSnow forecasts below for Lake Tahoe, Mammoth, Whistler, Utah, Colorado and the Tetons.

Lake Tahoe Snow Forecast

OpenSnow’s Lake Tahoe forecaster Byran Allegretto is calling for “Cloudy and windy today with showers and highs in the 40’s…Tonight heavier precip moves in with snow levels falling to 7,000 feet. We could see 4-13 inches of snow on the mountains. Friday the snow continues with snow levels around 6,000-6,500 feet. Winds will be gusting to 90 MPH on the mountain tops. Highs will be in the 30’s. We could see an additional 1-4 inches at lake level and 2-8 inches on the mountains.”

“Friday night colder air filters in with another wave of precip moving in. Snow continues with an additional 3-8 inches possible at lake level, and 5-15 inches on the mountains. Snow showers should linger into Saturday with winds still gusting to 65 mph on the mountain tops. We could see 1-5 additional inches. Highs will only be in the 20’s on the mountains and low 30’s at lake level.”

Mammoth Snow Forecast

Mammoth OpenSnow forecaster Howard Sheckter is expecting “Moisture will push inland over Northern California Thursday then shift south Friday where it will stall for a time over the Southern Sierra and Southern part of the Central Sierra.”

“Deep moisture with 850 MPH wind speeds of 40 knots Friday will enhance the orographic effect to provide heavy precipitation up the San Joaquin drainage to Mammoth Mountain, spilling over well into Western Nevada.”

“The Main Lodge to the Mammoth Crest is in for some 3 to 4.5 feet of snow by Saturday night.”

“The town of Mammoth will experience a snow level of between 7,500 to 8,500 feet until the cold air gets in here, sometime late midnight Friday night. So it will be very wet! The Dweebs [model] is estimating some 10 and 20 inches of snow with the snow level dropping to 7,000 feet by early Saturday a.m. or lower. If by chance the cold air gets into our area sooner, larger accumulations are possible in town.”

Whistler Snow Forecast

According to OpenSnow’s Larry Schick, a Whistler snow forecaster, “The next five days will bring a series of weather systems to British Columbia. It will be difficult to time when one will end and the next begin. All of these systems will produce snow at mid station, and up into the alpine. Snow amounts will be roughly 2-5” a day, but there is uncertainty, and there could be a little more or less each day. There will be a rain snow mix in the Village. During this pattern off and on pattern, there will be some brief periods of minimal snowfall or no snow – even some sunbreaks.”

Utah Snow Forecast

Evan Thayer, the OpenSnow Utah forecaster, says today, Thursday, will be warm and then, “…a windy day on Friday, then cold and snowy this weekend as a spring storm system drops into the region and brings mountain snowfall Saturday and Sunday. Another storm possible late next week.”

The models are forecasting “1-3″ of liquid, which could mean anywhere from 1 to 3 feet of snowfall for the Upper Cottonwoods.  So at the very least, it appears to be a decent storm,” says Thayer.

Colorado Snow Forecast

According to OpenSnow Colorado forecaster Joel Gratz “Thursday and Friday will be dry and mostly sunny. Then on Saturday expect gustier winds and more clouds, with snow starting Saturday later afternoon or at night and continuing through Monday morning. Snow totals should be in the 4-8 inch range with the softest powder on Sunday and perhaps Monday morning. After that, we’ll likely see another storm between April 15-20th.”

Teton Snow Forecast

Jackson Hole Mountain Resort is closing down for the season this weekend and it’s looking like there will be closing weekend pow! OpenSnow Teton forecaster Sam Collentine says “Thursday will be our final mostly dry day but we can expect cloudy skies as moisture increases across the region. Chances for precipitation will then increase on Thursday night and throughout the day on Friday as our next storm begins to make its presence felt.”

“This system will initially bring us moisture-laden, southwesterly flow and kick off periods of moderate to heavy snow by Friday night and into Saturday. The snow level will hover at or above 8,000 feet so look for all snow at GT [Grand Targhee] and all snow for the upper half of JHMR. Look for 4-8 inches at Jackson Hole through Saturday afternoon and 3-6 inches at Grand Targhee. ”

“We’ll then turn to Saturday night and early Sunday morning for the winds to transition to more of a westerly flow. This will bring in much cooler temperatures and drop the snow levels down to the valley floors. Snowfall rates will likely decrease to light to moderate snow through Sunday night but the snow quality should improve tremendously compared to Saturday.”
