Be prepared for slick roads on your way out the door this morning, and the potential for more very light showers through your Monday forecast. Low pressure tracking through to our north is keeping the threat of very light showers across our region today, with the best chance for wet weather lingering in the foothills and mountains through this evening. Valley areas may see some very light sprinkles today, but not much else is expected in our lower elevations. A Winter Weather Advisory is set to remain in effect through 4pm this afternoon in areas of the northern Sierra above 5000', and a Winter Weather Advisory is also in effect through 10am in Modoc County. Temperatures are mostly 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 our mountain areas on this President's Day morning. We'll continue to have cloudy skies through the day, and winds out of the south to around 15mph. High temperatures are projected to top out in the upper 50's to lower 60's in the valley, mid 40's to mid 50's in the foothills, mid 40's in the Sierra, and in the mid 40's to lower 50's in the Northern Mountains this afternoon.
High pressure will build into northern California on Tuesday and Wednesday. This will result in the return of sunny to mostly sunny skies, dry weather, and slightly warmer temperatures through the middle of this week. Temperatures will dip into the 30's to lower 40's overnight in the valley, and will top out in the lower 60's over the next couple of afternoons. High temperatures will also be slightly warmer for our foothill and mountain areas on Tuesday and Wednesday. The nex wet system is projected to arrive in our forecast late in the day on Thursday, and will potentially persist through Friday. Light rain and snow amounts are expected from this wave of wet weather, and we'll also see a modest drop in high temperatures late this week and this weekend. Models are currently split on whether or not to expect more rain on the way in your Saturday forecast, but if we do it will be light. Temperatures will be similar on Saturday to what we'll have for the end of this week, but we will see some clearing of our skies and warmer temperatures returning in your Sunday forecast. Mountain areas can expect travel impacts starting on Thursday night and persisting into the start of your weekend.
