Very modest changes are expected in your Wednesday forecast across Northern California. Sunny to mostly sunny skies are expected today, and temperatures will end up a degree or two cooler than yesterday. Skies are clear for the start of your Wednesday morning, and winds are mostly out of the East to 5mph. Temperatures are starting out in the mid 60's for the valley again this morning, and in the 40's to 50's in the mountains early today. We are expecting winds to shift to become out of the South late this morning, and that will help to keep high temperatures from getting as hot as Tuesday. South winds will be up to around 15mph for the valley, with gusts up to 25mph in the Northern portions of the valley this afternoon. Humidity will dip to as low as 15 percent later today, which is slightly higher than the last couple of afternoons. High temperatures are projected to end up in the low to mid 90's in the valley this afternoon, and mountain areas will mostly range from the mid 80's to low 90's later today. Fire danger will remain in the high range due to the warm temperatures, and low humidity later today.
Thursday is expected to be the coolest day of this week. Temperatures will top out in the low 90's for most of the valley, with a few cities still inching towards the mid 90's in the afternoon. South winds will be prevalent, and a few thin clouds will brush across the region. South winds will start to taper off Thursday evening. A high pressure system will build into the West Coast from the Pacific on Friday. That system will result in lower humidity, warmer temperatures, and stronger North winds developing across our region. Temperatures will end up back in the high 90's for the valley on Friday afternoon, humidity will likely dip to around 10 percent, and wind could gusts to as strong as 30mph out of the North. Fire danger will be extreme on Friday, and will stay elevated through the weekend. As of now, A Fire Weather Watch is expected to be in place from Friday morning through Sunday evening for a large portion of our area (mostly valley and foothills). That Fire Weather Watch will have the potential to be elevated to A Red Flag Warning this weekend. Temperatures will end up in the 102 to 108 degree range in the valley this weekend. Humidity will stay dangerously low, and winds will continue to be strong and out of the North. You're advised to use extreme caution this weekend. Please refrain from mowing your lawn, or using any kind of heavy machinery around dry brush from Friday through Sunday.
Temperatures will dip back into the mid to high 90's on Monday, and then in the low to mid 90's on Tuesday. We are expecting to stay dry through the extended forecast, but the cooling trend will result in a comfortable change of pace on the way for next week.
