727 FNUS56 KMTR 010742 CCA FWFMTR Fire Weather Planning Forecast for the San Francisco Bay Area and...CORRECTED Central California Coast National Weather Service San Francisco Bay Area 1242 AM PDT Mon Sep 1 2025 ...ELEVATED FIRE WEATHER THREAT IN THE INTERIOR MOUNTAINS THROUGH MONDAY EVENING DUE TO LOW RH AND MODERATE AFTERNOON BREEZES... .DISCUSSION...One more day of warm and dry conditions leading to elevated fire weather concerns before a cooling trend sets in Tuesday, and will continue through the remainder of the extended forecast. Elevated interior locations and locations above the compressed marine layer closer to the coast will see poor RH recovery overnight remaining in the 10%-25% range. Onshore flow will increase this afternoon out ahead of an upper level low approaching from the southwest while we transition from the influence of ridging to our east and the arrival of the offshore disturbance to our southwest. We are also watching a low probability-high impact scenario for elevated thunderstorms as early as late this afternoon that will continue into Tuesday. The North Bay, Bay Area and East Bay Hills are the favored locations for the non-zero chances of convection, with cloud to ground lightning and gusty winds as the primary concern. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. $$ CAZ505-011945- Coastal North Bay...Including Point Reyes National Seashore- 1242 AM PDT Mon Sep 1 2025 .TODAY... * Sky/weather.........Mostly sunny. * Max temperature.....72-80. * 24 hr trend......Little change. * Min humidity........55-65 percent. * 24 hr trend......Little change. * 20-foot winds.......Northwest winds 10 to 15 mph. * Chance of Thunder...0 percent. * CWR.................0%. * Marine layer........500 ft asl. .TONIGHT... * Sky/weather.........Partly cloudy. * Min temperature.....51-56. * 24 hr trend......Little change. * Max humidity........75-95 percent. * 24 hr trend......10 percent wetter. * 20-foot winds.......West winds 10 to 15 mph. * Chance of Thunder...0 percent. * CWR.................0%. * Marine layer........1000 ft asl. .TUESDAY... * Sky/weather.........Mostly sunny. * Max temperature.....66-74. * Min humidity........65-75 percent. * 20-foot winds.......West winds 5 to 10 mph. * CWR.................0%. .EXTENDED... .TUESDAY NIGHT...Partly cloudy.
