Heavier rain and snow are on the way to northern California this week. A colder and more potent system has arrived along our Northwest Coast this evening and will persist through at least early in the day on Tuesday. Snow levels could dip to as low as 2000', but the Winter Weather Advisories are in effect in portions of the Northern Mountains down to 2500', and portions of Shasta County, the Sierra, and Cascades down to 3000'. Up to 8 inches of snowfall will be possible down to around 3500', and we could see up to 15 inches of snow in some localized areas. Valley areas will see limited rain showers during this first storm. Some showers may linger in the valley into the early portion of your Tuesday, and mountain areas could have scattered snow showers into late tomorrow afternoon. Gusty South winds can also be expected as this system moves through. Sustained winds could reach 25mph in the valley tonight, and we could potentially see gusts up to 35mph. Temperatures will fall into the high 30's to low 40's in the valley tonight and mostly into the 20's to 30's in the mountains on Tuesday morning. High temperatures will end up in the high 40's to low 50's on Tuesday in the valley, and mountain areas will to out in the 30's to 40's.
The next storm system will arrive Wednesday afternoon and evening across northern California. That system is expected to be stronger than the Monday into Tuesday system, and could end up with snow levels down to around 1500'. Rain totals look like they will be more abundant in the valley, and snow totals are projected to end upin the 1 to 2 foot range for most mountain areas above 3000'. Some localized snow totals of up to 3 feet will be possible during the Wednesday into Thursday system. The National Weather Service out of Sacramento has currently issued a Winter Storm Watch to last from Wednesday afternoon through Thursday night. This could very well be upgraded to a Winter Storm Warning as we get closer to the evening. We'll also have the potential for heavier rain and thunderstorms in the valley on Thursday. Another issue with the Wednesday through Thursday system will be stronger South winds in our region. A Wind Advisory or a High Wind Watch or Warning may be issued as we get closer to the middle of this week. The current outlook includes gusts up to around 40mph on Wednesday, with the potential for stronger gusts on Thursday. Areas around thunderstorms may also have localized stronger winds on Thursday. Most of the active weather is currently expected to wrap up by Friday morning, but there will be a chance for scattered rain and low elevation snow on Friday morning. Snow could potentially fall to the valley floor in Redding on Friday morning if the showers do linger through that time.
Another wet system will take aim at our regoin from late Friday night through the day on Saturday. that system is currently not projected to be as substantial as either of the systems that will precede it earlier in the week. Some light to moderate showers will be likely in the valley and a mix of light to moderate rain and snow showers will be likely in the mountains. We'll get a much better idea of what to expect for your weekend and beyond with the model runs over the next few days.
