Hot and dry conditions persist through Saturday across the interior due to high pressure over the region. Breezy onshore winds develop each afternoon and evening with gusts reaching 20 to 25 mph through favored gaps, passes, valleys, and coastlines. The marine layer influence will bring good to moderate overnight humidity recoveries in the lower elevations, but the hills and thermal belts remain mild and dry overnight. Monsoonal moisture from the south continues to present a very low, but non- zero, chance for elevated convection through Saturday. A gradual cooling and moistening trend begins Sunday and extends through next week. ...Discussion from SFOFWFEKA... Hot and very dry weather will begin to peak today with the hottest valleys reaching over 110 with exceptionally dry RH in the single digits. Overnight recoveries will also become increasingly poor at mid and upper elevations as low as 30 percent. Marine influence will shallow and become restricted to the coast. Similar hot and dry conditions will continue through the weekend. There is a very slight chance (5-10%) of dry thunderstorms over the Trinity Alps Sunday. Thunderstorm chances over high terrain will increase early next week but any storms will also become increasingly wet. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-231015- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 310 PM PDT Fri Aug 22 2025 ...ELEVATED FIRE WEATHER THREAT CONTINUES THROUGH THE WEEKEND DUE TO HOT AND DRY CONDITIONS AND AFTERNOON WINDS...
