Be prepared for a chilly start to the day, breezy north winds, and slightly cooler high temperatures across northern California in your Friday forecast. High pressure remains parked off the coast in the Pacific and is keeping our region mostly dry today, but an area of low pressure tracking through to our north will result in a dip in temperatures and the potential for some light showers close to the Oregon border. Skies are clear to mostly clear to start your Friday and we are expecting to stay sunny to mostly sunny through your Friday. Temperatures have dipped into the 30's to 40's in the valley and foothills, and into the teens to lower 30's in our mountain areas overnight. Winds will be out of the north to 15mph, with gusts up to around 30mph today. The strongest winds in the valley are expected early to mid afternoon and the biggest impacts can be expected in areas along I-5. A High Wind Warning will be in effect in Modoc County from 7am this morning through 7pm tonight. Sustained winds up to 20mph out of the north, and gusts up to 65mph will be possible there. High temperatures will end up in the mid 60's in the valley, upper 40's to upper 50's in the foothills, and 40's to lower 50's in our mountain areas this afternoon.
The low pressure to our north will track south and end up off to our east on Saturday. This will result in another inside slider event like the one we had on Wednesday, but winds are not expected to be as strong as what we had that day. Sustained winds up to 25mph, and gusts up to 40mph out of the north will be possible on Saturday afternoon. Temperatures will end up a degree or two cooler for most cities on Saturday. The winds will diminish Saturday night into Sunday, but Sunday is still expected to be breezy. Temperatures will warm by several degrees compared to Saturday as high pressure builds back into northern California.
Models continue to be split on whether or not a chance for some light showers can be expected in the north valley and our mountain areas on Monday. For now, I'm keeping a slight chance for light showers in your Monday afternoon forecast. Temperatures will also end up 5 to 10 degrees cooler on Monday afternoon. This is all hinging on low pressure tracking down the Pacific off the coast of California. By Tuesday that area of low pressure is expected to be to our south, and we'll see dry weather and similar temperatures. Models are keeping us dry and warmer on Wednesday and Thursday of next week. The next chance for widespread showers is expected to arrive Friday of next week, and potentially last into next weekend.
