Wet weather has been tracking across northern California overnight, but the rain and snow showers are expected to diminish through the day. I'd still plan on keeping my umbrella handy as you head out the door, but most of you will be dry by this afternoon. The exception is in the Sierra, where some rain and snow showers could linger into this evening. A Winter Weather Advisory is still in effect through 10am in northern Trinity County and portions of Siskiyou County down to 4000' through 10am this morning. Up to 6 inshes of snowfall still looks possible in those areas through your morning commute. Snow levels in that area area down to around 3500'. No watches, warnings, or advisories are in effect in the Sierra or Southern Cascades, but modest snowfall down to around 4500' is possible through the day. Some mountain trave impacts are expected this morning, but should become less of an issue by the afternoon commute. A Wind Advisory is also in effect in Modoc County through 4pm this afternoon. Southwest winds to 35mph are projected, and gusts up to 55mph are possible in that area today. Temperatures are starting out in the low to mid 40's in the valley, 30's to 40's in the foothills, and 20's to 30's in the mountains this morning. Winds will mostly be out of the south to 15mph today, and skies will stay partly to mostly cloudy as the rain chances diminish this afternoon. High temperatures are projected to end up in the mid to high 50's in the valley, in the 40's to lower 50's in the foothills, and in the upper 30's to low 50's in our mountain areas later today.
High pressure building into northern California will result in a mostly dry and warmer weather pattern this weekend, and the vast majority of our region will conitinue to see that trend through at least the middle of next week. Temperatures in the valley will dip into the 30's overnight this weekend, and end up in the upper 50's to lower 60's in the afternoons. There will be a decent potential for fog development on Saturday morning and a chance for fog on Sunday morning. Foothill areas will continue to dip into the 30's to lower 40's overnight, and top out in the upper 40's to mid 50's this weekend. Mountain areas will dip into the teens to lower 30's on Saturday and Sunday morning's, and then end up in the 40's to lower 50's for both afternoons this weekend.
High pressure is projected to dominate our extended forecast in most areas, and will result in dry weather, and above average temperatures for the start of next week. Monday and Tuesday look very similar to what's projected for your weekend, but we could see some coastal and far northern zone showers move through on Tuesday evening. Additional warming is expected on Wednesday into Thursday, and the current projections are putting valley high temperatures in the upper 60's to lower 70's by the middle of next week.
