458 FNUS86 KMTR 192052 FWLMTR ECCDA Discussions National Weather Service SAN FRANCISCO BAY AREA 152 PM PDT Sat Sep 19 2026 ##################################################################### ## ## ## Discussions from the latest FWF below ## ## ## ##################################################################### ...Discussion from SFOFWFMTR... Offshore winds were observed this morning, with Mt. St. Helena recording 6 hours of 20-25 mph winds from the NNE. The offshore gradient is relaxing as the sea breeze takes over, and winds are expected to remain onshore and follow the typical diurnal pattern for the next several days. Warmer weather today will yield to a brief cool-down Sunday through Monday before a more substantial warming trend kicks off Tuesday. By Wednesday and Thursday inland temperatures will reach the 90s with a very shallow marine layer and low RH. There is no sign of wetting rain through next weekend at least. ...Discussion from SFOFWFEKA... Moderate fire weather conditions will give way to rapid warming and drying this weekend. By Sunday, interior highs will return to the 90s with minimum RH into the teens. Strong thermal belts will also worsen RH recovery at mid and upper slopes into early next week and marine influence will pull much closer to shore. For the most part, winds will remain weak and terrain driven. Such conditions will persist through most of next week, allowing fuel drying to accumulate. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-200900- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 152 PM PDT Sat Sep 19 2026 Offshore winds were observed this morning, with Mt.
