Cloudy skies and a slight chance for some scattered showers are ahead for your Tuesday evening, and a very decent chance for rain and snow are ahead for your Wednesday. Low pressure off the coast of Central California has already brough mostly cloudy skies to Northern California today and will continue to be the main driving factor in your forecast tomorrow. Temperatures will be very cold again overnight, with valley areas expected to dip into the mid to high 30's. Mountain areas will mostly end up in the teens to 20's on Tuesday morning. The cold airmass in place will result in the potential for low elevation snow as precipitation ramps up across our regoin tomorrow morning. There will be a chance for a mix of rain and snow in Redding and Red Bluff for the start of the day. Foothill areas of Butte County including Paradise and Magalia will also have a chance for some snow showers in the morning. Snow levels will rise as we head into your afternoon and are expected to end up at around 3500'. Areas of the Northern Mountains are expected to get the most abundant snowfall, with up to around a foot of snow possible at Mt. Shasta. Our portions of the Sierra will likely see a couple of inches of snow with limited travel impacts heading into tomorrow evening. High temperatures will continue to slide for the middle of your work week. valley areas are projected to end up in the mid 40's to low 50's, while mountain areas top out in the mid to high 30's on Wednesday afternoon. Most of the showers will wrap up as we head into your Wednesday evening.
The next chance for wet weather is expected to arrive in our region on Thursday and will persist through Thursday night. Portions of the Northern end of the valley and the Northern Mountains will have a decent potential for some showers continuing into the early portion of Friday. Snow levels will start out at around 4000' on Thursday morning, but will climb into the 5000' to 6000' range by the evening. Temperatures will end up slightly warmer for both your morning low temperatures and your daytime high temperatures on Thursday. In the valley we'll be starting out in the high 30's to low 40's on Thursday morning and we'll be topping out in the low 50's on Thursday afternoon.
The next round of wet weather is projected to arrive across Northern California late Saturday morning and could last through early Monday. Snow levels will start out at around 5000' on Saturday, but will slide down to around 4000' on Sunday. Mountain travel impacts are expected for those hitting the roads this weekend. There is a deent chance for showers continuing into your Monday forecast, but wet weather will not be as likely for your Christmas Eve on Tuesday. There is still a lot of uncertainty in your Sunday through Christmas Day forecast, so we will be monitoring that closely for you to bring you the latest projected impacts when we get a clearer model consensus.
