High temperatures increase this weekend to a few degrees above average, which linger into next week. High pressure aloft will compress the marine layer gradually and provide further drying at locations above 1,000 feet. Afternoon humidity drops into the teens at these locations; much better moisture retention at lower elevations. Winds remain onshore, but will become breezy in the afternoons during peak heating. ...Discussion from SFOFWFEKA... Low daytime RH values in the teens and single digits, especially in Trinity, Lake, and northeastern Mendocino. Winds will mostly be diurnally and terrain driven, with locally breezy conditions over the ridges. Poor overnight recoveries with values in the mid 20`s to mid 30`s is forecast for the far interior ridges, while onshore marine moisture will continue to promote good RH recoveries for area below the inversion (<2500 feet). Some slight improvement in the minimum RH and recoveries are expected for Friday and through the weekend. An enhanced breezy west and southwest is forecast for Friday over the interior higher terrain where wind gusts over 20 mph are probable (50 to 70%), especially in Trinity and Lake counties. Higher chances for wind gusts over 20 mph exist for Lake and southern Mendocino County Saturday. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-300900- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 157 PM PDT Fri Aug 29 2025 High temperatures increase this weekend to a few degrees above average, which linger into next week.
