441 FXUS66 KMTR 250001 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 459 PM PDT Fri Apr 24 2026 ...New AVIATION, MARINE... .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... (00Z TAFS) Issued at 459 PM PDT Fri Apr 24 2026 VFR-MVFR conditions continue tonight and Saturday. A few areas of light drizzle are possible tonight and Saturday morning. A low pressure system nearby on Saturday will produce showers. Showers over the north Central Coast may become moderate to heavy Saturday afternoon and evening. Vicinity of SFO...VFR. A few showers are possible Saturday afternoon and evening. West wind diminishing to 5 to 12 knots tonight through Saturday. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...VFR-MVFR. Light coastal drizzle is possible tonight and Saturday morning. Showers also developing Saturday with a low pressure system nearby. Showers may become moderate to heavy in the afternoon and evening. There could be enough instability for isolated lightning later Saturday with low pressure development nearby, but for now will wait on including VCTS in the current 00z KMRY and KSNS TAFs. && .MARINE... (Tonight through next Wednesday) Issued at 443 PM PDT Fri Apr 24 2026 Expect mainly 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.
