** Evening Storm Update – Arctic Blast Set to Bring Cold Temperatures and a Fresh Blanket of Snow to the Foothills and Sierra **
45°F – We are on track for rain, snow and cold Tuesday for western Nevada County. The storm has slowed some which will delay the onset of rain and snow until later in the day and evening. That may affect evening commute in the Grass Valley area as well.
With that in mind, it’s looking at this time, that the heavier snow should begin in the Cascade Shores / Banner Mtn areas in the mid to late afternoon, and in the evening sometime for the GV / NC areas. The snowfall forecast looks about the same, which is as follows:
3-6 inches of snow in the Grass Valley, Nevada City areas
5-10 inches in the Cascade Shores / Banner Mtn areas
A dusting, up to an inch of snow possible down to 1500 ft (Lake of the Pines / Penn Valley) areas by Wednesday.
Up to 2 1/2 feet of snow is possible in the high Sierra above 8000 ft, up to 2 foot over the passes, with up to a foot of snow in the Truckee / Tahoe areas.
Winter storm warnings are are in effect for the Sierra and the foothills above 2500 ft through Wednesday. Expect heavy snow and strong winds as the cold front passes Tuesday evening with strong winds and reduced visibility due to blowing snow at times, especially in the upper foothills and Sierra.
Tuesday evening into Wednesday will be difficult travel in the foothills, so if you don’t have to travel during this time frame, it would be advisable to stay home and wait for the roads to be cleared during the day Wednesday.
Travel in the Sierra is not advised from Tuesday AM through Wednesday as heavy snow and blizzard conditions will make travel difficult or impossible.
Foothill Forecast: Increasing clouds Monday night with rain developing late morning Tuesday. Snow level 4500-5000 ft lowering throughout the day Tuesday. Rain changing over to snow above 3000 ft mid to late afternoon. Snow showers continuing Tuesday night with the snow level lowering to 1500-2000 ft. Show showers Wednesday, continued cold. Partly cloudy and cold Thursday and Friday with a few flurries, continued cold.
Highs should only be in the 30’s to around 40 Wednesday and Thursday, with lows in the low to mid 20’s. Some upper teens possible in the upper foothill locations with the deeper snow cover.
For those travelling to the Sierra later in the week on Thanksgiving, expect a few snow showers, breezy and very cold, with highs only in the 20’s and 30’s, lows in the single digits and teens, with -10 to -20 below zero wind chill.
** Although we are not expecting a heavy snowfall in the foothills, there will be moderate snowfall, accompanied by winds. So, there’s always the possibility of power outages with storms like these. It is advisable, that all foothill residents, especially those in the upper foothills above 3000 ft to prepare now for the snow and cold, winter driving conditions and for possible power outages. Make sure you have an alternative heat source in case of power outages.
