Sunny skies and slightly cooler temperatures are on the way in your Friday forecast. High pressure centered to our Southeast is keeping us sunny to mostly sunny and dry, but low pressure to our Northeast will keep high temperatures in check this afternoon. Temperatures are starting out in the low to mid 60's in the valley and foothills, and in the 40's for most mountain areas. Winds are starting out light and out of the East this morning, but will shift to become out of the Southeast to 10mph this afternoon. Lighter winds overnight have allowed humidity to recover better than 24 hours ago. Valley areas are starting out with humidity levels well above 50 percent, but we'll see a dip into the 15 to 30 percent range this afternoon. Dry fuels are keeping fire danger moderate today, but the remainder of the factors are positive compared to the last few days. Skies will be sunny in the valley and mostly sunny in the mountains this afternoon. High temperatures will range from the high 80's to mid 90's in the valley, the low to mid 80's in the foothills, high 70's to mid 80's in the Sierra, and high 70's to high 80's in the Northern Mountains this afternoon.
High pressure will build into Northern California this weekend as the low pressure to our Northeast continues to move East. Your 4th of July forecast looks very average for this time of year and that should make for comfortable conditions on Saturday. We'll be sunny to mostly sunny, and a little warmer than today on Saturday. Valley areas will start out in the low to mid 60's and will end up in the mid to high 90's, foothill areas will start out in the low to mid 60's and end up in the mid 80's to low 90's, Sierra locations will start out in the 40's and end up in the mid to high 80's, and Northern Mountain areas will start out in the 40's and end up in the mid 80's to low 90's on Saturday afternoon. Winds will be out of the South to around 10mph on Saturday afternoon and evening. Almost identical conditions are on the way for your Sunday, but we could see an uptick in temperatures by a degree or two compared to Saturday on Sunday afternoon.
There is not much of a change of pace on the way as we head into the start of next week, but an area of low pressure to our North will result in a very modest dip in temperatures as we head towards the middle of next week. High temperatures will end up slightly below average on Tuesday through Thursday. Valley areas will start out in the 60's and end up in the high 80's to mid 90's, foothill areas will start out in the low 60's and end up in the low to mid 80's, and mountain areas will dip into the 40's and end up in the 80's for the afternoons. Skies will be sunny to mostly sunny, and we will have a slight chance for some shower or thunderstorm activity in areas closest to the Oregon border.
