741 FXUS66 KMTR 310508 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 1008 PM PDT Sat May 30 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 1005 PM PDT Sat May 30 2026 - Todays temperatures will be near or slightly above normal - Monday will be the warmest day of the week - Slightly cooler temperatures for the end of the work week into next weekend && .SHORT TERM... Issued at 1005 PM PDT Sat May 30 2026 (Today and tonight) Weak ridging stalls offshore for most of today before amplifying somewhat to our north tonight, setting the stage for a brief jump in temperatures on Monday. Before that, we will see a notable increase of around 5 degrees from Saturdays highs. Interior locations in the North Bay Valleys, South Bay, East Bay Hills and Salinas Valley south of Soledad have the best chance (60%-100%) of reaching 80 degrees, with the remainder of the interior away from coastal influences in the 70s, and 60s for coastal areas. Marine layer will struggle to make much progress beyond the immediate coast into the beginning of the week. && .LONG TERM... Issued at 1005 PM PDT Sat May 30 2026 (Monday through Saturday) Expect another jump around 5-10 degrees on Monday across the interior with another day of relatively unimpressive amplification of the ridge and weak, unorganized jet stream flow at H30. Split upper flow regime through the middle of the week will keep temperatures similar Tuesday through Thursday. The potential cool down expected for the end of the week into next weekend continues to evolve with deterministic guidance now backing off the deeper troughing advertised the past couple of days. The net result would be closer to normal temperatures, and more pleasant weather and dry conditions through the extended forecast. && .AVIATION... (06Z TAFS) Issued at 929 PM PDT Sat May 30 2026 A mix of clear skies and coastal stratus tonight. HAF, MRY, SNS, SFO, and OAK are the ones to watch, listed in order of decreasing probabilities. Moderate onshore winds will decrease overnight before returning Sunday afternoon. Vicinity of SFO...The terminal remains VFR, although a patch of stratus is developing over the Peninsula. The strong onshore winds are gradually decreasing, but held on longer than I thought they would. The probability for ceilings Sunday morning is around 40%, but the window is short enough to capture in a TEMPO group. The afternoon will almost certainly be clear as the onshore winds return. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...MRY just developed a ceiling out of nowhere. I expected that to happen tonight, but not this early. I`m not sure that this first cloud will survive the night, so I`m keeping the first few hours of the TAF VFR for now. && .MARINE... (Tonight through next Friday) Issued at 929 PM PDT Sat May 30 2026 High end small craft advisories are in effect, with buoys reporting occasional gusts to gale force. A fresh northerly breeze will continue through Sunday. Seas will build in response and become rough leading to hazardous conditions over the coastal waters through Sunday and into Monday morning. && .MTR WATCHES/WARNINGS/ADVISORIES... CA...Beach Hazards Statement from 5 AM PDT Sunday through late Monday night for CAZ006-505-509-529-530. PZ...Small Craft Advisory until 3 AM PDT Monday for Pigeon Pt to Pt Pinos 10-60 NM-Pt Arena to Pt Reyes 0-10 nm-Pt Pinos to Pt Piedras Blancas 0-10 nm. Small Craft Advisory until 3 AM PDT Sunday for Pigeon Pt to Pt Pinos 0-10 nm-Pt Reyes to Pigeon Pt 0-10 nm.
