FXUS66 KMTR 101850 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 1150 AM PDT Tue Mar 10 2026 ...New AVIATION... .KEY MESSAGES... Updated at 243 AM PDT Tue Mar 10 2026 - Near to slightly above normal temperatures today - Extended period of above normal temperatures sets in on Wednesday - Widespread Minor HeatRisk tomorrow through Saturday, with increasing areas of Moderate HeatRisk Sunday into the beginning of next week && .UPDATE... Issued at 853 AM PDT Tue Mar 10 2026 Low level stratus encompasses most interior areas of the South Bay and Central Coast this morning. These clouds will dissipate and give way to mostly sunny sky conditions this afternoon with temperatures forecast to be in the 60s to lower 70s. Otherwise, the ongoing forecast remains on track. We will continued to look into how warm/hot this weekend and into early next week will be! RGass && .SHORT TERM... Issued at 243 AM PDT Tue Mar 10 2026 (Today and tonight) Today will be the coolest day through the extended forecast. The EPAC ridge that will dominate our pattern for the next week and beyond will continue to build today. However, a broad trough axis extending from the Great Basin into NorCal interacting with the building ridge will produce gradient forcing for the gusty northwest winds along the coast, especially for the North Bay and Bay Area coastlines, along with a tight thermal H85 gradient across NorCal. Temperatures along the coast will be slightly below normal with gusty northwest winds this afternoon. High temperatures inland will run about 5 degrees above normal for most locations with occasionally breezy northwest winds. While surface winds ease this evening, H85 flow will begin to increase and become offshore once again. With light and variable surface winds tonight into Wednesday morning, along with the developing offshore boundary level flow producing mostly clear skies, more efficient radiational cooling will result in lows in the 40s and even upper 30s for higher elevations. && .LONG TERM... Issued at 243 AM PDT Tue Mar 10 2026 (Wednesday through Monday) By Wednesday afternoon, the warming trend through the remainder of the extended forecast will be in full swing. Highs will be in the 70s for a majority of our area, some 60s along the coast and low 80s in the southern Salinas Valley. We'll see more widespread 80s for the remainder of the work week into the weekend with 90s in the southern Salinas Valley by Sunday, expanding in area by the beginning of next week. We'll see widespread Minor HeatRisk set in Wednesday and persist through Saturday with increasing areas of Moderate HeatRisk Sunday and Monday. The warm temperatures will persist through much of next week. Deterministic guidance is beginning to pick up on some offshore troughing as the impressive dome of high pressure meanders east well beyond the current forecast range. && .AVIATION... (18Z TAFS) Issued at 1150 AM PDT Tue Mar 10 2026 VFR through the TAF period. Mostly moderate winds build in the mid afternoon with breezy to gusty winds at HAF, SFO, and OAK.

Winds build again into Wednesday afternoon, but with less gusts. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...VFR through the TAF period. Moderate west to northwest winds last into the night before becoming light. && .MARINE... (Today through Sunday) Issued at 853 AM PDT Tue Mar 10 2026 Near gale to gale force winds affect the waters through the day and into the night. As a result, very rough seas will build in the outer waters. Winds reduce into early Wednesday, but rough seas and fresh to strong northerly breezes will keep hazardous conditions around through the weekend. && .MTR WATCHES/WARNINGS/ADVISORIES... CA...None.
