375 FXUS66 KMTR 091117 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 417 AM PDT Mon Mar 9 2026 ...New AVIATION... .KEY MESSAGES... Updated at 323 AM PDT Mon Mar 9 2026 - Patchy fog lifts by mid-morning - Near normal temperatures today and Tuesday. - Breezy conditions along the coast and coastal mountains today. - Above normal temperatures return Wednesday into next weekend. && .SHORT TERM... Issued at 323 AM PDT Mon Mar 9 2026 (Today and tonight) Patchy dense fog developed overnight primarily along the coast but also into the Salinas Valley as onshore flow has returned after a weekend of onshore flow and above normal temperatures. However the onshore flow early this morning will be short-lived as low level boundary layer flow becomes offshore once again, albeit weak, with weak surface ridging under west-east ridge axis aloft. Expect any remaining patchy fog near the coast to lift by mid-morning. Weak onshore flow then returns again tonight as the west-east ridge axis weakens and shifts south. Overnight lows tonight into early Tuesday will hover around the mid-40s almost area wide. && .LONG TERM... Issued at 323 AM PDT Mon Mar 9 2026 (Tuesday through Sunday) Tuesday will be the coolest day through the remainder of the extended forecast with highs right around or slightly above normal. The brief `cool down` on Tuesday is best described by a dip in H85 temps by a few degrees (Celsius) under a series of embedded progressive weak shortwaves rounding the top of a building ridge that will dominate our synoptic pattern for the remainder of the extended forecast and beyond. By Wednesday afternoon the center of the building ridge nudges closer to the coast with H85 temps lifting back up into the lower teens (Celsius). This will mark the beginning of persistent ridging into the foreseeable future with H50 heights approaching daily and monthly records (as noted in the Sunday evening update) by the end of the week into next weekend. Temperatures will jump well above normal by the end of the week with && .AVIATION... (12Z TAFS) Issued at 417 AM PDT Mon Mar 9 2026 Currently a mixed bag of LIFR-VFR at the terminals with fog/stratus along the Pacific Cost. Interior locations are not out of the woods yet with low dew point depressions and still a few hours of cooling to go; however, there is moderate confidence that they will remain VFR. Diurnal winds are expected to increase this afternoon and remain elevated overnight. Vicinity of SFO...Currently VFR with westerly flow. IFR/low-end MVFR stratus is remaining confined to the Pacific Coast. Moderate confidence that this will remain the case through the morning. Westerly winds will increase through the day, becoming gusty this afternoon. Low probability of gusts reaching 35 knots. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...Currently LIFR and calm at both terminals. An Otter Eddy in the Monterey Bay is bringing varying conditions to the region. Fog will likely persist through the morning at SNS with MRY likely to remain transient between fog and LIFR stratus through the morning. Diurnal winds will prevail. Moderate confidence on MVFR conditions returning to the terminals tonight. && .MARINE... (Today through Saturday) Issued at 323 AM PDT Mon Mar 9 2026 Hazardous conditions from strong to near gale force northerly breezes are expected through Wednesday morning. Frequent gale force gusts are expected across the outer waters and along the coastal jet region of Point Reyes. As a result, very rough seas will build in the outer waters. Conditions will slightly improve beginning Wednesday afternoon, but rough seas and fresh to strong northerly breezes will keep hazardous conditions around through the week. && .MTR WATCHES/WARNINGS/ADVISORIES... CA...None. PZ...Small Craft Advisory from 3 PM this afternoon to 9 PM PDT this evening for Mry Bay. Gale Warning until 3 PM PDT Tuesday for Pigeon Pt to Pt Pinos 10- 60 NM-Pt Arena to Pt Reyes 0-10 nm-Pt Arena to Pt Reyes 10- 60 NM. Small Craft Advisory until 3 PM PDT Tuesday for Pt Reyes to Pigeon Pt 0-10 nm. Small Craft Advisory from 9 AM this morning to 3 PM PDT Tuesday for Pigeon Pt to Pt Pinos 0-10 nm-Pt Pinos to Pt Piedras Blancas 0-10 nm. && $$ SHORT TERM...JM LONG TERM....JM AVIATION...Sarment MARINE...Sarment Visit us at www.weather.gov/sanfrancisco Follow us on Facebook, X, and YouTube at: www.facebook.com/nwsbayarea x.com/nwsbayarea www.youtube.com/nwsbayarea |
