** Unsettled tonight and Wednesday. A quick moving, but potent storm moves in late Wednesday into Christmas Eve with significant foothill snow! **
43°F – 2 day storm total for Cascade Shores – 5.06 inches of rain.
Outlook and Forecast: The foothills and Sierra got hammered with very heavy rain and snow over the past few days from a powerful, moisture laden storm that moved in from off the Pacific. Areas in western Nevada county received anywhere from 3.5 to well over 5 inches of rain over the past 3 days, with Cascade Shores reporting a 2 day total of 5.06 inches, 4.06″ fell yesterday on the 21st.
The Sierra got buried with very heavy snow yesterday. Areas around the Sierra picked up around 3 feet of snow just yesterday, with Sugar Bowl summit reporting a 4 day total of 57 inches, nearly 5 feet of snow!
Forecast models have been fairly consistent and in agreement that big changes are in store for Nor Cal over the next few days, as the mild “Pineapple Express” storm is winding down and moving out of the area. This will be replaced by a cold storm originating from the gulf of Alaska. It will bring much colder temperatures and with it, significant foothill snow Wednesday night, lasting through Christmas Eve.
For that reason, the National Weather Service has issued a Winter Storm Warning for the foothills above 2500ft, from from 1 AM Thursday to 4 AM PST Friday for snow. Expect snow-covered and slippery roads with significant travel delays and chain controls beginning Wednesday night, lasting through Thursday, possibly into Thursday night. Power outages are also a possibility in western Nevada county with drought stressed trees and broken branches taking out power lines.
If the forecast holds, snowfall amounts may be pretty impressive.
For now – Tonight and Wednesday is looking unsettled and colder with a few showers possible – snow level 3500-4000 ft. By Wednesday night however, conditions turn much colder as an Alaskan cold front approaches from the north. Snow may begin as early as the evening sometime in the foothills, picking up in intensity overnight, with falling snow levels. Snow continues Thursday, heavy at times, with the snow level 2000-2500 ft, falling as low as 1500 ft in isolated showers. Christmas day looks cold and partly cloudy with a snow shower or flurry possible.
Expect snow amounts, approx – 8-16 inches between 3000-4000 ft, 5-8 inches between 2500-3000 ft, 2-4 inches between 2000-2500 ft, a dusting, up to 1 inch between 1500-2000 ft.
