Be prepared for cooler temperatures and light showers across northern California today. Low pressure tracking through the Pacific Northwest is projected to drag the tail end of a band of showers through our region on Wednesday, and most areas are expecting very modest showers through the day. A Winter Weather Advisory has been issued for the northern area of Trinity County above 4500' from 6am this morning through 2pm this afternoon. Up to 5 inches of snow will be possible in that area during that time. The remainder of our region will see very light showers starting in our northwestern zones in the morning, and moving through the mid valley into the Sierra this afternoon. Snow levels will be down to around 4000' in the Northern Mountains, and down to around 5000' in the Sierra and Southern Cascades today. Temperatures are starting out in the 30's to 40's in the valley this morning and in the 20's to 30's in the mountains early today. There is potential for some fog development early this morning in the mid valley. Skies will be partly to mostly cloudy and winds will be up to 10mph out of the southeast. High temperatures will be much cooler than Tuesday. Valley and foothill areas can expect high temperatures in the mid 40's to lower 50's, while mountain areas will mostly end up in the upper 30's to upper 40's this afternoon.
A break from the wet weather is expected from late tonight through Thursday afternoon. Fog development will be possible again on Thursday morning across our region. Temperatures will end up a few degrees cooler on Thursday morning and a few degrees warmer on Thursday afternoon in most areas. The next wet system will bring showers to our region Thursday night through early in the afternoon on Friday, and this next system does look somewhat more substantial than the one expected for today. Snow levels will dip to as low as 3500', and some mountain travel impacts will be likely for the start of your Friday morning. Showers are currently expected to wrap up Friday night, and dry weather will take hold for your weekend.
High pressure will build back over our region this weekend, and that will result in dry weather and above average temperatures. Looks like this will be a good weekend to get outdoors. Valley temperatures will dip into the 30's overnight and will top out in the upper 50's to lower 60's through the weekend. We'll then stay mostly dry for the start of next week, with just a chance for showers in our far northern zones on Monday and Tuesday.
