Short Term
Issued at 1038 PM PDT Fri Oct 23 2026 (Today and tonight)
Gusty offshore flow across the North Bay Interior Mountains is ongoing tonight, with the windy and dry conditions dropping MinRH values in the 20s for some locations. Fire weather concerns would be higher for this area had we not received the recent wetting rainfall. The offshore flow regime should mostly limit fog development early this morning but still can't be ruled out entirely in some of the river valleys in Sonoma County.
Temperatures today will be around 5 degrees warmer than Friday and near normal for this time of year. The gusty winds across the North Bay will begin to ease by late this morning, with a beautiful day in store area wide across our CWA as upper level ridging builds overhead.
Long Term
Issued at 1038 PM PDT Fri Oct 23 2026 (Sunday through next Friday)
Sunday will almost be a carbon copy of today for the North Bay and Bay Area, with the Central Coast seeing temperatures warm another few degrees. Confidence and consensus in the synoptic pattern is poor after Monday. An upper trough shifts south to our latitude on Monday bringing a return of onshore flow, however the overall progressive pattern is struggling with the depth of the trough and how another system well offshore interacts with the flattening trough as it moves into the Great Basin. Despite the uncertainty in the overall pattern, any troughing or ridging will continue to be progressive and low amplitude, with no large temperature fluctuations or precipitation chances until the end of next week when the NBM seems to pick up on what the current ECMWF deterministic has depicted for next Friday into the weekend, troughing with increasing rain chances.
