After the cold front moved through Tuesday morning we were left with cool and unstable air behind it giving us isolated showers and eventually thunderstorms in Glenn and Butte Counties.
A strong thunderstorm developed in Willows around 5:45pm with a confirmed funnel cloud at around 6:15 putting the thunderstorm east of Willows between I-5 and Highway 45. There was another funnel cloud (possibly a tornado) just north of Durham about an hour later. The National Weather Service will decide Wednesday morning whether or not they will send a survey crew to the path of the storm.
We have seen snow levels near 4000 feet and may eventually drop to around 3500 feet especially by Wednesday night into Thursday morning. However, any significant accumulation (1 foot of higher) will be above 5000 feet. There is a Winter Storm Warning in the mountains east of the valley so be sure to keep a close eye on the road conditions before any travel in the mountains. The winds are expected to pick up from the south at 10 to 20 mph with gusts up to 30 mph and aren't expected to die down until the end of the week.
The forecast models continue to bring us an off and on chance for rain through at least the beginning of next week with some of the heavier rain falling Friday evening and Saturday. Once all is said and done through Friday morning the valley could pick up between a half of an inch to an inch of rain and we could add at least another inch if not more for Friday, Saturday and Sunday. This won't be a drought buster but it will be good to get some decent rain and snow in the Northstate.
