Northeast winds will develop Wednesday night and this will cause an accelerated drop in Minimum RH for Thursday, with values down to the low teens to some single digits for zones 283, 277 and 264. Inland heating will intensify Thursday, with a further increase Friday. The heat and low RH will remain through the weekend. Afternoon westerly wind surges will also bring fire weather concerns, particularly in zones 264 and 276. Monsoonal moisture will begin clipping the eastern zones starting Friday. There is a small but impactful chance (5-10%) for isolated dry thunderstorms starting Saturday for Trinity County. Chances for thunderstorms may then trend higher through Sunday and early next week with additional monsoonal moisture. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-201030- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 319 PM PDT Tue Aug 19 2025 ...ELEVATED FIRE WEATHER THREAT BEGINNING THURSDAY THROUGH EARLY NEXT WEEK DUE TO HOT TEMPERATURES AND CURING FUELS...
