FNUS56 KMTR 232141 FWFMTR Fire Weather Planning Forecast for the San Francisco Bay Area and Central California Coast National Weather Service San Francisco Bay Area 241 PM PDT Sun Aug 23 2026 .DISCUSSION...The marine layer remains compressed to around 1000 feet with fluctuations between 1000 to 1200 feet expected this week. There is a low (5%) chance of storms developing across northern Napa County early Monday morning due to the arrival of a weak shortwave trough. Confidence that storms will develop is low and any convective potential decreases by Monday afternoon. Coastal drizzle and patchy fog are likely directly along the coastline through the week. Slightly above normal temperatures and very dry conditions continue above the marine layer with poor daytime humidity values between 10-20%. Little to no humidity recovery is expected at the higher elevations with overnight RH values peaking between 20-30%. Diurnally breezy winds continue across favored locations through the upcoming week. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. $$ CAZ505-240945- Coastal North Bay...Including Point Reyes National Seashore- 241 PM PDT Sun Aug 23 2026 .TONIGHT... * Sky/weather.........Partly cloudy then becoming mostly cloudy. * Min temperature.....50-55. * 24 hr trend......Little change. * Max humidity........100 percent. * 24 hr trend......Little change. * 20-foot winds.......Southwest winds 5 to 10 mph. * Chance of Thunder...0 percent. * CWR.................0%. * Marine layer........1000 ft asl. .MONDAY... * Sky/weather.........Mostly sunny.
