We'll see some modest changes on the way in your Wednesday forecast. Low pressure tracking through to our north will provide partly to mostly cloudy skies, slightly cooler temperatures, and breezy north winds across northern California on Wednesday. Thin clouds have already moved into our region overnight, and more are ahead for your afternoon. Most areas will see partly cloudy skies today. Temperatures are starting out in the 30's to 40's in the valley and foothills, while mountain areas are ranging from the teens to lower 30's this morning. Winds will be out of the north to around 15mph today, with gusts up to 20mph. High temperatures are projected to end up in the mid 60's to low 70's in the valley, upper 50's to mid 60's in the foothills, and 50's to lower 60's in mountain areas this afternoon. We'll be staying dry despite the increase in clouds on the way for today.
The pattern seems to be shifting through your extended forecast, and that is welcome news on the way. Low pressure areas tracking through the Pacific Northwest will bring a decent cooling trend to our region for the remainder of this work week, and will bring a chance for some modest showers to mountain areas closest to the coast and Oregon border Thursday afternoon through early Friday morning. There will be potential for snow levels dipping to as low as 2500', but there will not be a lot of moisture hitting the ground. No travel impacts are expected from this brief shot of wet weather Thursday/Friday. Temperatures will cool back into the low to mid 60's in the valley on Thursday and then down into the mid to high 50's on Friday. Foothill areas can expect high temperatures in the low to mid 50's on Thursday, and then down into the mid to upper 40's on Friday afternoon. Mountain areas can expect high temperatures in the 40's to 50's on Thursday, and then mostly 40's on Friday afternoon.
A more robust wet system will bring the potential for widespread light showers to our region from Friday night through early in the day on Saturday. This will likely only bring a trace of rain into the valley, with some mountain areas closest to the Oregon border seeing closer to a quarter of an inch of rainfall. We'll dry back out for a short period on Saturday afternoon before a more substantial wet system is expected to move in from Saturday night through early Monday. The latest models are showing a decent amount of rain from during this period, with valley areas ranging from around half an inch to an inch of rain, but those models could change as we get closer to the weekend. Snow levels are mostly expected to dip to around 5000' this weekend. Showers will continue into early Monday and then we will have the potential for more wet weather as we head towards the middle of next week!
