551 FXUS66 KMTR 241919 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 1219 PM PDT Fri Apr 24 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 1217 PM PDT Fri Apr 24 2026 - Additional rounds of drizzle/light rain likely tonight through Sunday - Below normal temperatures this weekend before a warming trend kicks off early next week && .SHORT TERM... Issued at 1217 PM PDT Fri Apr 24 2026 (This evening through Sunday) A mix of low (mainly over the Pacific), mid, and high level clouds are seen via satellite imagery early this afternoon. However, where low clouds were slower to clear late this morning, we could see temperatures not reach their forecast maximum temperatures. This is especially so over the North Bay. We are still forecasting mid 60s to lower 70s across the interior with upper 50s to mid 60s in coastal areas this afternoon as low clouds continue to dissipate. A cut-off mid/upper level low pressure is forecast to develop off of the Bay Area and northern Central Coast tonight and gradually shift inland across the Central Coast on Sunday. This will likely result in drizzle and/or light rain across much of the Bay Area and northern Central Coast through the weekend. Rainfall amounts are forecast to be light, generally a few hundredths of an inch or so through Sunday afternoon. The greatest potential to see greater than 0.10" will be across the Santa Cruz Mountains and the Santa Lucia Range due to orographic lift along the coastal slopes. While rainfall amounts are forecast to be light, slick roadways are anticipated this weekend. In addition to the drizzle/light rain potential, cooler temperatures are also forecast for the weekend with afternoon highs up to 10 degrees below seasonal averages. On the flip side, increased cloud cover will result in overnight/morning lows up to a few degrees above normal. && .LONG TERM... Issued at 1217 PM PDT Fri Apr 24 2026 (Sunday night through next Thursday) Drier conditions are expected for Monday through next weekend with a gradual warming trend through the period. However, general troughing across the region will limit any type of significant warm up with interior areas warming into the mid 70s by Thursday afternoon. Meanwhile, coastal areas will remain in the upper 50s to 60s. The 6- 10 Day Temperature Outlook from the CPC indicates the warming trend. && .AVIATION... (18Z TAFS) Issued at 1138 AM PDT Fri Apr 24 2026 Clouds this morning continue to erode leaving a mix of mainly MVFR to VFR conditions. Expect this trend to continue with most sites seeing a few hours of VFR cigs, the exception might be KHAF. Low clouds return tonight, which should bring widespread MVFR cigs, perhaps a few pockets of IFR. Drizzle will be possible along the coast, which could drop cigs and vis even more. Medium to high confidence in the forecast. Vicinity of SFO...Satellite this morning shows clods eroding east of SFO, while maintaining west of the airport. VFR conditions may prevail over the next few hours if clouds remain on the western half of the range ring. Otherwise expect conditions to bounce/flirt with MVFR and VFR conditions for the next few hours before becoming VFR for a brief period. A return of cigs is expected tonight and should have a similar trend tomorrow morning. Medium to high confidence in the forecast. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...Monterey Bay has cleared out this morning, with pockets of cumulus remaining anchored to the terrain. Most sites will be VFR for the afternoon, with KMRY having lingering MVFR cigs for the next couple of hours. MVFR cigs return tonight along with the chance for some coastal drizzle. && .MARINE... (Today through Wednesday) Issued at 859 AM PDT Fri Apr 24 2026 Choppy seas will begin to gradually subside today and continue to do so into the weekend. Mainly moderate northwest winds continue through today and become moderate west to northwest breezes for the weekend. Drizzle and light rain remain in the forecast, favoring the southern waters and areas along the coast this weekend. && .MTR WATCHES/WARNINGS/ADVISORIES... CA...None.
