The North Bay and inland valleys are expected to be in the 90's with some areas creeping towards the 100 degree mark. The hot temperatures are expected to continue into Monday
There's also going to be critically low humidity and sustained winds between 15-25 miles per hour with gusts up to 60 miles per hour
Higher elevations of the North Bay in Marin, Sonoma, Napa, and Solano counties are under the red flag warning from 11pm Friday evening until 5pm Sunday afternoon, but that could change and last longer.
The Sonoma County Sheriff's Department issued a warning to residents on Friday.
"Outdoor burning is not recommended this weekend as grass fires could spread rapidly. A combination of strong strong winds, low relative humidity and warm temperatures can contribute to extreme fire behavior."
