Storm Tracker Forecast: Mostly dry & very chilly end to 2021

  • Updated

Get ready for a very chilly start to your Thursday forecast. Clear skies overnight have allowed for much cooler temperatures to settle into northern California this morning. Frost is widespread across northern California early today, and we have had patchy areas of dense fog develop early this morning. You'll want to give yourself a few extra minutes to scrape your windshield on your way out the door this morning, and a little extra time to deal with impacted visibility from the fog on your morning commute. We'll have clouds increase through the day, and will end up partly to mostly cloudy across most of our region by this afternoon. Low pressure to our north will track to the southeast over the next 24 hours, and that will create what's called an inside slider. These events are usually accompanied by the potential for mountain snow, and gusty north winds. There will be a slight chance for light showers brushing across northern California late Thursday into very early Friday, but we'll otherwise be staying dry through this weekend. High pressure off the coast, and to our east in Nevada are both acting as sorts of buffer zones to keep most of the wet weather out of our region to end 2021. Temperatures are mostly starting out in the 20's to 30's in the valley and foothills, and teens to 20's in our mountain zones this morning. Winds will be out of the north to 10mph early today, but some of our higher elevations will have the return of south winds for your afternoon and evening. High temperatures are projected to top out in the mid 40's to low 50's in the valley, mid 30's to mid 40's in the foothills, and 30's in our mountain zones today. Light showers will mostly be possible in our mountain zones tonight, and there will be a very slight chance for scattered showers popping up in the valley late Thursday night. The best chance for any showers will be in areas closest to the Oregon border through early Friday.

The trend of dry weather and very chilly temperatures will persist through this weekend. Valley areas can expect low temperatures in the 20's to 30's and high temperatures in the mid 40's to lower 50's through this weekend. Foothill areas will have low temperatures in the 20's to 30's and high temperatures in the 30's to mid 40's through this weekend. Mountain areas will have low temperatures in the single digits to 20's and high temperatures in the 30's for the most part through this weekend. Frost will likely be an issue over the next few mornings, and fog will also be possible in the morning hours over the next few days. We'll be partly cloudy to mostly sunny on Friday, then mostly sunny to sunny on Saturday. Clouds will begin to increase on Sunday, and the next wet system is projected to move into northern California on your first Monday of 2022. Snow levels will be higher from the winter storm arriving on Monday, with areas of Shasta County potentially getting snow down to 2000', and snow levels ranging from 3000' to 4500' in the foothills and Sierra. The other big impact from the storm moving in next week will be very strong winds. Some higher peaks of the Sierra will have the potential for wind gusts up to 100mph if the current model track holds for next week. We'll continue to track the latest model data to bring you any updates on weather impacts heading your way through your extended forecast.
