441 FXUS66 KMTR 232351 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 351 PM PST Mon Feb 23 2026 ...New AVIATION, MARINE... .KEY MESSAGES... Updated at 200 PM PST Mon Feb 23 2026 - Above normal temperatures and dry conditions this afternoon - Widespread North Bay rainfall returns tonight into Tuesday - Warming and drying trend kicks off Wednesday && .SHORT TERM... Issued at 200 PM PST Mon Feb 23 2026 (This evening through Tuesday) High clouds streaming over the region ahead of the incoming weather system. Comfortable temperatures in the 60s across the region with the thickest clouds over the North Bay. Moist and mild southerly flow this evening in warm frontal structure but no excessively strong winds forecast given the lack of cold advection. A few stray showers late this afternoon and early evening near the Mendocino county line otherwise mainly dry through 10 pm tonight. Warm frontal light rains develop overnight across the North Bay, especially Sonoma county and the coastal hills down to Marin. Clouds and southerly winds will keep temps mainly in the 50s overnight. Wet roads for the early morning commute mainly for areas north of the Golden Gate. && .LONG TERM... Issued at 200 PM PST Mon Feb 23 2026 (Tuesday night through next Sunday) Weak to moderate AR and associated warm frontal structure will keep steady rains pointed from San Francisco northward from 12-18z Tuesday morning with the heaviest rains continuing across Sonoma county. Light rain will gradually shift southward across San Mateo county and the Santa Cruz mountains during the day Tuesday with some light rain pushing into the East Bay. The Santa Clara Valley and points southward will see little or no rain with this system on Tuesday. Rain will continue through the evening commute for much of the Bay Area with wet roads but generally light winds. Rainfall totals by late Tuesday night of 1-3 inches for the North Bay with some some localized 4 inch totals in the Sonoma hills and around Mt Tamalpais. Rain amounts around 1 inch in San Franciso/Oakland with amounts tapering off to around 0.25 for San Jose. Santa Cruz mountains may top off around 1.5 inches but the weakening nature of the system looks to keep amounts generally light for the Santa Cruz mountains with only 0.10-0.25 for the Santa Lucia hills in Monterey County. So in general expect beneficial late February rains from this system with the only place for some possible nuisance flooding across portions of Sonoma county. However, no signs of the system stalling or intensifying beyond Tuesday evening so confidence remains high for no widespread flooding impacts. Any lingering showers end by 12z Weds with perhaps some soupy morning fog in the moist airmass. High pressure then builds with highs warming back into the 60s and lower 70s with mild overnight lows generally in the 50s at least through Saturday. Next feature of interest is a weak cutoff low that could impact the region later Sunday into Monday. The main impact would to drop temperatures back down to more seasonable levels with a slight chance of instability showers though no significant rainfall is forecast. Long range trends beyond that keep the pattern somewhat active but not seeing any signs of notable March storms or rainfall. && .AVIATION...
