Grab your umbrella, and be prepared for travel impacts if you're heading into the foothills or mountains today. Low pressure dropping south off the coast in the Pacific will bring rain, snow, and the potential for thunderstorms into our forecast today and Wednesday. The biggest impact over the next two days is expected to be the heavy snowfall, and that will extend down into the foothills. A Winter Storm Warning will be in effect through 10am Wednesday in Shasta County down to 2500', where up to 2 and a half feet of snow can be expected. A Winter Storm Warning will be in effect from noon Tuesday through 7pm Wednesday for the foothills and Northern Sierra down to 3000', where up to 2 feet of snow will be possible. Trinity County will be under a Winter Weather Advisory through 4am Wednesday down to 2000', where up to a foot of snow will be possible. Mountain travel impacts look very likely for Tuesday and Wednesday. Light to moderate rain is expected in the valley, but there is also a potential for thunderstorm development both Tuesday and Wednesday. Thunderstorms could be accompanied by gusty winds, small hail, and we can't rule out the formation of funnel clouds or weak tornadoes over the next 2 days. Temperatures are starting out in the 30's to 30's in the valley and foothills this morning and in the teens to lower 30's in our mountain areas. Winds will be out of the south to 15mph, with gusts up to around 30mph possible. High temperatures are projected to climb into the upper 40's to mid 50's in the valley, and into the mid 30's to mid 40's in the foothills and mountains both today and Wednesday.

The area of low pressure will move into Southern California and start to track to our east on Thursday, but the potential for light to moderate mountain rain and snow will linger in our region. Valley areas are projected to stay dry after Wednesday evening. Temperatures will be chilly overnight, but get a warmer in the afternoons late this week. Expect valley areas to dip into the 30's to 40's overnight, foothill areas to dip into the 20's to lower 40's, and mountain areas to mostly dip into the teens to 20's. High temperatures will likely climb back into the lower 60's in the valley on Thursday, and then mid 60's to lower 70's on Friday. Foothill areas can expect high temperatures in the 40's to lower 50's on Thursday, and high temperatures mostly in the 50's on Friday. Mountain areas will have high temperatures ranging from the mid 40's to lower 50's later this week.

The current projections are keeping our region dry and warm on Saturday. Expect conditions to be very similar to what we'll have on Friday. Models are hinting at a weak wet system brushing through northern Californai late Sunday into Monday of next week. At the moment this looks like a fairly quick moving system with minimal impacts expected across northern California during that time. Models are then keeping our region dry and mild from Tuesday through the middle of next week. Longer range models are hinting at the potential for wet weather returning late next week into next weekend, but that's still too far off to have any serious confidence in at this time.

It was nice to receive some rain and mountain snow around northern California late Sunday and early Monday. Thankfully a change to our overall weather pattern is underway, and many more chances of rain are coming!
