A 2000ft marine layer will compress to around 1200ft for the weekend. Moderate onshore flow will persist, becoming breezy each afternoon with minRH values away from or above the marine layer down to about 15-25 percent. Temperatures will be slightly above normal for the weekend, cooling back to normal for much of next week. ...Discussion from SFOFWFEKA... Minimum RH will continue to lower Thursday, down to the mid to low teens for the far interior. Winds will mostly be diurnally and terrain driven. A passing shortwave will cause a slight westerly to southerly wind surge thursday afternoon. This will be the driest day, but overnight recoveries will be 30 to 50%. The marine layer is relatively deep, and this is allowing for further inland push of marine influenced air. Minimum RH and recoveries will then trend higher through the weekend. Stronger westerly afternoon wind surges are forecast Friday and Saturday for Lake County where wind gusts over 20 mph are probable. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-290000- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 500 AM PDT Thu Aug 28 2025 A 2000ft marine layer will compress to around 1200ft for the weekend.
