473 FNUS86 KMTR 310833 FWLMTR ECCDA Discussions National Weather Service SAN FRANCISCO BAY AREA 133 AM PDT Sun Aug 31 2025 ##################################################################### ## ## ## Discussions from the latest FWF below ## ## ## ##################################################################### ...Discussion from SFOFWFMTR... Large scale sinking air, compressional warming and drying aloft, a strong low level temperature inversion coupled with diurnal late August solar warming will continue to produce hot and dry conditions over the interior today and Monday. Conditions remain cooler along the immediate coast due to a shallow marine layer and generally light to locally moderate afternoon sea breezes. Above the shallow marine layer very low daytime humidities and poor overnight recoveries have persisted just away from the immediate coast. Winds remain onshore, but breezy afternoon winds will elevate the fire weather threat in the interior mountains, especially through favored gaps and passes. ...Discussion from SFOFWFEKA... Dry weather will continue through Monday with low daytime RH values in the teens and poor to moderate humidity recoveries in areas well away from the coast. Winds will generally be diurnally and terrain driven. Today a period of enhanced afternoon winds with gusts to 25 mph is expected. Next week a warming and drying trend is expected with high temperatures forecasted to peak in the upper 90s to near 105 across the interior valleys on Tuesday. There is also a slight chance of afternoon and evening thunderstorms on Tuesday, mainly in Trinity county. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-312045- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 133 AM PDT Sun Aug 31 2025 Large scale sinking air, compressional warming and drying aloft, a strong low level temperature inversion coupled with diurnal late August solar warming will continue to produce hot and dry conditions over the interior today and Monday.
