The marine layer depth is near 1500 feet. Expect poor overnight recoveries (20-30%) and poor daytime humidity retention (10-30%) to continue above the marine layer. Dry and hot weather will continue inland while cooler, maritime influenced weather continues closest to the coast and bays. An upper level trough over the eastern Pacific will move northeastward through late week and the weekend, nudging the Four Corners high pressure system slightly eastward. ...Discussion from SFOFWFEKA... Marine influence has just started to increase across the area and will continue to increase through the end of the week. High clouds Friday will aid in the warmest interior temperatures pulling back closer to 90 with RH closer to 25 percent. Mid and upper slope recoveries will also improve though remain poor on higher peaks. Winds will remain gentle and from the west. Tropical moisture moving overhead Friday will bring a very slight (5%) chance of isolated, dry thunderstorms Friday morning and through the afternoon, but simple high level clouds and virga are the most likely outcome. Warmer, near average conditions will return Sunday and into early next week. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-211000- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 300 PM PDT Thu Aug 20 2026 The marine layer depth is near 1500 feet.
