Snow here for the weekend
The rain will turn into snow just in time for the weekend.
A cold front from the northwest is pushing into the Truckee-Tahoe area, moving previous snow levels from the 9,000 to 10,000 foot level down to lake level through the weekend, said National Weather Service Meteorologist Rhett Milne.
Snow is likely this morning, Milne said, but snow showers should continue through the weekend.
“Over the last week we have been getting a warm-moist flow off the Pacific,” Milne said. “The new front should put a fire hose of moisture into the Sierra.”
The new cold air mass will also be accompanied by strong winds, Milne said, with a speed of up to 100 miles per hour over the ridges.
The cold front will push the weekend lows into the single digits by Sunday, with highs struggling to reach the 30s, Milne said.
The quick drop in temperature has the potential to generate lake effect snow at Lake Tahoe, where a relatively warm lake releases moisture into comparatively cold air, creating clouds and snow-showers, Milne said.
He said the storm will dissipate early next week, with the potential for a “wimpy” system next Wednesday.
Milne said the El Nino predicted for this year has been moderate.
“El Nino typically splits the storm track to the north and south, leaving the northwest dryer and Southern California wetter,” Milne said. “We are in between, so it can really go either way. We have no statistics on how we will end up.”
He said the last 10 years have had warmer winters on average, and expects this winter to be warmer than normal as well.
Roschelle Jenkins, Caltrans assistant public information officer, said that Caltrans is preparing for chain controls and road sanding.
She also said blowing snow may reduce visibility on the roads.
