337 FNUS86 KMTR 020921 FWLMTR ECCDA Discussions National Weather Service SAN FRANCISCO BAY AREA 221 AM PDT Tue Sep 2 2025 ##################################################################### ## ## ## Discussions from the latest FWF below ## ## ## ##################################################################### ...Discussion from SFOFWFMTR... There is a 15-20% chance for isolated showers and thunderstorms essentially across the Diablo Range from Alameda Co to interior southern Monterey Co through the early afternoon. Chances for interior North Bay areas are around 10% or less. Outside of this threat, a gradual cooling trend starts today, with the marine layer improving over the next couple of nights. ...Discussion from SFOFWFEKA... Poor RH recoveries are expected in the higher elevations. Today, low RH values and triple digits are forecasted. In addition, isolated dry thunderstorms are also possible in the interior, primarily for Trinity County. Gusty and erratic outflow winds of 40 to 60 mph are possible with any storms that do form. Plume domination at ongoing fires is possible. Regardless of the thunder threat, instability will support a breezy day, which will elevate fire risk as conditions remain hot and dry. Wednesday through the end of the week gradual cooling is expected with highs mainly in the 80s by Saturday. ##################################################################### ## ## ## Complete a discussion for each ECCDA segment below ## ## When done click transmit, product sent as KMTRFWLMTR ## ## ## ##################################################################### ECC010-022130- St Helena ECC Dispatch- DISCUSSION FOR Marin and Sonoma and Napa Counties 221 AM PDT Tue Sep 2 2025 There is a 10% or less chance for isolated showers and thunderstorms essentially across the interior portions of the North Bay counties through the early afternoon.
