Be prepared for wet weather and cooler temperatures across northern California today. An area of low pressure is trackiing south along the California coast early this morning, and is expected to continue to push at least light rain and snow through our region today. Moisture amounts are limited with this system, but most areas are expected to see at least a little wet weather. Snow levels are mostly down to around 3000' in the Northern Mountains, and down to around 3500' in the Sierra and Cascades today. Temperatures are starting out in the 40's in the valley, upper 30's to mid 40's in the foothills, and 20's to 30's in our mountain areas this morning. We'll have moslty cloudy skies, with some limited clearing expected this afternoon. The potential for light rain and snow will continue through the day, but the heaviest amounts are expected through around the early afternoon hours. High temperatures are projected to top out in the lower 50's in the valley, 30's to 40's in the foothills, and 30's to 40's in most mountain areas today. Winds will mostly be out of the south to 10mph, but our northern zones could see a return to modest north winds this afternoon. The potential for showers will wrap up across most of our area this evening, but the Sierra could see lingering showers through very early Saturday morning. Some modest travel impacts are possible in our mountain areas.
Clearing skies, mild conditions and warmer temperatures are expected on Saturday. We'll be cooler for your morning hours, but the afternoon looks to end up around 5 to 10 degrees warmer than Friday. Low temperatures in the valley will end up in the 30's, and high temperatures are projected to top out back up in the upper 50's to lower 60's. Foothilll areas will mostly start out in the 30's, and then end up in the 40's to 50's on Saturday afternoon. Mountain areas can expect lows in the teens to 20's on Saturday, and high temperatures in the 40's for most locations. The next wet system will move into our region on Sunday, and this one looks to pack more of a punch than the one heading through on Friday. It will also have lower snow levels, with some areas down to around 1500'. Several inches of snow will be possible in our mountain areas, a few inches of snow will be possible in our foothill areas, and around a half inch or so of rain will be possible in the valley from early Sunday through early Monday. Mountain travel impacts are expected from Sunday through the start of next week. We will also be substantially cooler on Sunday, with highs in the valley in the 40's, 30's to 40's in the foothills, and mostly 30's in our mountain areas. Valley areas will end up slightly warmer than Sunday on Monday, but our mountain areas may end up a little cooler.
A break from the wet weather is expected from mid day on Monday through Tuesday afternoon. We'll have partly cloudy skies on Monday, and then increasing clouds through the day on Tuesday. The next more substantial wet system could arrive in our region as early as Tuesday night, and the current projections have very heavy rain and snow in our forecast for the middle of next week. Projections are also hinting at a mix of rain and snow down onto the valley floor in Redding overnight Tuesday through early in the day on Wednesday. A couple inches of rain is projected for the valley and foothills, several inches of snow is projected in the foothills, and our higher elevations may be measuring snowfall in feet from the middle to latter part of next week. This is all still several days off and is subject to change, but if this pattern holds we are in for very wet and active weather from late Tuesday through early Friday of next week. Longer range models are showing even more active weather on the way from next weekend through the start of the following week. This is good news for our dire water supply, but will also bring major travel impacts to our region if the current outlook holds.
