** Alaskan storm to bring cold and significant foothill snow beginning tonight, lasting into Christmas Eve! **
31°F – Rainfall since midnight for Cascade Shores – .21 inches of rain.
Outlook and Forecast: Other than a few light showers last night, the foothills enjoyed clear and cold conditions today. A very cold Alaskan air mass has been settling in over the area today and is a precursor of what’s to come. To illustrate, Cascade Shores reached it’s high temperature at midnight last night with a high of 41°. The temperature fell most of the day, eventually recovering only to a high of 39, we never made it out of the 30’s, despite bright sun and light winds. Temperatures will continue to fall overnight and Thursday in advance of the Alaskan storm overtaking the area.
The cold Alaskan storm mentioned in last night’s forecast is right on track, and the storm’s timing remains unchanged. It should arrive sometime after midnight with increasing snow and wind. Latest forecast charts show one slight change, that the storm looks to begin as an all snow event for elevations above 2500 ft. That means Grass Valley and Nevada City and all elevations above should see all snow out of this storm. Snow amounts also remain unchanged.
Expect total snowfall amounts as follows:
- 8-16 inches between 3000-4000 ft
- 4-8 inches between 2500-3000 ft
- 2-4 inches between 2000-2500 ft
- A possible dusting, between 1500-2000 ft.
Winter Storm Warnings for the foothills remain in effect above 2500 ft, from 1 AM Thursday morning to 4 AM PST Friday morning for snow. Snow may begin sometime after midnight tonight in the foothills above 2500 ft, picking up in intensity by morning, with falling snow levels. Snow will continue Thursday, heavy at times, with the snow level 2000-2500 ft, falling as low as 1500 ft later in the day. Thursday night looks cold with a chance of snow showers. Continued cold Christmas day with a snow shower or flurry possible.
Expect snow-covered and slippery roads with significant travel delays, chain controls and also (soft) closure of the “Big Hill” out of Cascade Shores, beginning late Wednesday night, lasting through Christmas Eve, into the evening and night. As already mentioned, power outages are a possibility in western Nevada county with drought stressed trees and broken branches possibly taking out power lines, so be prepared for that, just in case.
