302 FNUS86 KMTR 071159 FWLMTR ECCDA Discussions National Weather Service SAN FRANCISCO BAY AREA 459 AM PDT Mon Sep 7 2026 ##################################################################### ## ## ## Discussions from the latest FWF below ## ## ## ##################################################################### ...Discussion from SFOFWFMTR... A warming and drying trend begins today with a return to above normal temperatures by midweek. Upper level ridging is expected to strengthen and shift westward over southern California early to midweek. This continues to inhibit marine layer redevelopment and, it it does redevelop, will keep it compressed to around 500 feet. Minimal overnight humidity recoveries and poor daytime humidity retention are expected across the higher elevations through late this week with nocturnal drying possible along the highest peaks. Winds remain light through late week with locally breezier winds expected along the coast and mountain gaps/passes. ...Discussion from SFOFWFEKA... An exiting weather system will maintain up to a 15 percent chance of showers or thunderstorms over northern Trinity and interior Del Norte through early evening, though measurable rain is not expected. High pressure building over the region Monday through mid-week will bring much warmer and drier conditions. High temperatures in interior valleys will climb into the 98 to 102 degree range Tuesday through Thursday, with afternoon humidity levels dropping between 12 and 22 percent. Winds will follow standard daily patterns, blowing uphill during the day and down the valleys at night. Brief offshore winds Wednesday morning will spread warm temperatures and lower humidity closer to the coast before fog and low clouds rebuild late in the week. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-080000- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 459 AM PDT Mon Sep 7 2026 A warming and drying trend begins today with a return to above normal temperatures by midweek.
