932 FNUS56 KMTR 181014 FWFMTR Fire Weather Planning Forecast for the San Francisco Bay Area and Central California Coast National Weather Service San Francisco Bay Area 314 AM PDT Mon Aug 18 2025 .DISCUSSION...Only slightly warmer conditions for today with some compression to the marine layer, leading to quick erosion of inland low clouds. Expect a gradual warming trend as a ridge of high pressure builds through the week. Winds will weaken as this ridge builds becoming light a temperatures peak (upper 90s to low 100s) on Thursday and Friday. Minimal overnight cooling is expected Thursday and Friday across the higher elevations where low temperatures will only drop into the upper 60s to mid 70s. Overnight recoveries will stay fair to good for areas within the marine layer but for areas above it (approx. 2000 ft) overnight recoveries will remain poor. Dry daytime conditions will persist through the entire week with poor humidity retention across the interior. The driest conditions will be in the interior Central Coast where daytime humidity minimums will drop into the low teens. While Thursday and Friday look to be the peak, conditions may be slow to improve as onshore flow looks to only slightly increase into the weekend. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. $$ CAZ505-182215- Coastal North Bay...Including Point Reyes National Seashore- 314 AM PDT Mon Aug 18 2025 .TODAY... * Sky/weather.........Mostly sunny.
