Cooler high temperatures are on the way in your Friday forecast, but we also have the return of dry north winds ahead for today. High pressure is parked off the coast in the Pacific and low pressure is tracking through the Pacific Northwest today. The low pressure to our north will usher in cooler high temperatures this afternoon, and as it tracks to it's southeast it will bring gusty north winds back into our forecast. This will be another iside slider event, and will drive elevated fire danger concerns through this weekend. Skies are mostly clear for the start of your Friday morning and will stay sunny to mostly sunny through the day. Temperatures are starting out in the 50's to 60's in the valley, 40's to 50's in the foothills, and 30's to 40's in our mountain zones this morning. 10 to 20 mph north winds are expected today, and gusts could reach up to around 25mph this afternoon and evening. This will result in elevated fire danger on the way for your Friday afternoon. High temperatures are projected to end up in the low to mid 80's in the valley, and in the 60's to mid 70's in our foothill and mountain areas this afternoon. Winds will continue to become stronger out of the north tonight.
Stronger winds, low humidity, and very dry fuels on the way for this weekend has prompted the National Weather Service out of Sacramento to issue a Fire Weather Watch for the valley and foothills from late Friday night through Monday afternoon. Sustained north winds to 25mph look likely, and gusts in the 35 to 45mph range are going to be possible both days this weekend. Humidity will likely dip into the single digits to teens over the next several afternoons, and will not recover well overnight. We'll also have a warming trend on the way through this weekend. Valley areas will mostly end up in the mid to high 80's, foothill areas will top out in the 70's to low 80's, and most mountain areas will end up in the 70's this weekend. Looks like it's going to be a warm and very windy day on Mother's Day Sunday, so you may want to plan for indoor activities to avoid the wind.
We'll have a similar set up to our forecast on Monday, but high pressure will start to build back into northern California. Winds will still be strong out of the north, but will more than likely not be as strong as Saturday or Sunday. The high pressure building in will kick off a more substantial warming trend early to mid week next week. Temperatures will climb back into the upper 80's to lower 90's in the valley, while foothill and mountain areas top out in the 70's to lower 80's on Monday afternoon. The ridge of high pressure will then become centered over northern California from Tuesday through Thursday of next week. This will put a stop to the gusty north winds, but will leave us will substantially warmer temperatures on the way for the middle of next week. The current projections put valley areas in the mid to high 90's, and foothill and mountain areas in the 80's to potentially lower 90's by Wednesday. We'll stay hot and dry through at least Thursday, but could see some relief from the heat late next week into next weekend.
