March 20, 2017
TRUCKEE, Calif. — After several days of mild and spring-like weather, snow and rain is expected to return this week to the Tahoe-Truckee region.
According to the National Weather Service in Reno, the first storm is expected Tuesday with a second — and potentially stronger storm — for the end of the week.
For the first storm, 4 to 8 inches of snow is possible Tuesday at along higher Sierra passes, such as the Mt. Rose and Echo summits, according to a Monday morning special weather statement from NWS-Reno.
"Donner Pass could see occasional slushy accumulations Tuesday with accumulating snow on the road becoming more likely Tuesday evening as snow levels drop," the statement reads.
Meanwhile, "a few inches" of snow is possible at lake level and lower elevation areas in Truckee.
Precipitation will begin in the Sierra late Monday night with the heaviest precipitation expected Tuesday morning through early afternoon," according to Monday’s statement. "Winds will pick up today with the stronger winds expected Tuesday."
Snow levels are forecast to start at 7,000 to 8,000 feet by Tuesday morning, dropping to 5,500 to 6,500 feet by Wednesday morning.
Over the weekend, NWS-Reno posted a graphic on its Facebook page that suggested the following, among other things:
• The heaviest snow will fall between Tuesday night and Wednesday morning.
• 10 to 20 inches of snow is possible along the Sierra crest
• Up to 1 foot of snow is possible above 7,000 feet.
• Up to 3 inches of snow is possible down to 6,000 feet.
Moving forward, the next storm is set to arrive Friday into Friday night, according to a long-term forecast from NWS-Reno, which as of Monday admits it's too early to predict potential snow and/or rain totals.
"… Saturday will see convective snow showers behind the surface front as the cold pool aloft moves overhead,” according to the forecast. “The next system is now faster in the latest model runs and may move in by Sunday afternoon. However, it will be moving in from the Gulf of Alaska and won`t have as much moisture to work with.
“In addition, it will be colder with snow levels likely to start out near or below 6,000 feet. The active pattern does look to continue into next week. However, the systems look to be dropping more from the Gulf of Alaska so they will have less moisture and be cooler."
