Area Forecast Discussion National Weather Service San Francisco CA 1050am PDT Monday May 12 2025 Issued at 926am PDT Monday May 12 2025 A band of light rain is coming through the interior East Bay, the South Bay, and the Monterey Bay region with isolated to scattered showers behind the boundary. The rain band is expected to continue moving through the Central Coast through the rest of the day. Isolated thunderstorms remain in the forecast behind the front, and we will continue to keep an eye on the conditions through the rest of the day. DialH .SHORT TERM... (Today and Tuesday) Issued at 100am PDT Monday May 12 2025 A cold front with upper-level support will be the name of the game over the next two days. Said cold front remains just off the California Coast with rain just beginning to reach the ground in Mendocino County (just to the north of our CWA). Cloud cover and light rainfall will expand in coverage through the morning. Rainfall totals will have a northwest to southeast gradient of 0.20" to 0.00" respectively with locally higher totals in the higher terrain of the Bay Area. Interior Monterey and San Benito Counties may not receive measurable precipitation, but light drizzle can be expected, especially in the higher terrain with the help of orographic lift. Strong and gusty onshore winds will continue with the strongest winds expected in the higher terrain, gaps, and passes where gusts up to 40mph are expected. Widespread gusts of 20-30mph can be expected elsewhere. The post-frontal environment will have a low probability (<15%)/high impact threat for thunderstorms. If a thunderstorm were to develop the threats include lightning, small hail, and locally heavy rainfall and gusty winds. Long Term (Wednesday through Sunday) Issued at 100am PDT Monday May 12 2025 Heigheights will be slow to rebuild Wednesday as the open wave exits to the east. There still remains uncertainty in the extended forecast as an upper-level shortwave ridge building into the Eastern Pacific Ocean Thursday quickly gets flattened by an upper-level shortwave trough in the Gulf of Alaska by Friday. These two features will propagate through the upper-level pattern and are resulting in 33% of global ensemble members suggesting an inside slider like pattern setting up over the weekend with the ECMWF (European Centre for Medium-Range Weather Forecasts) and Canadian as the primary drivers. As of now they are forecasting the upper- level low only reaching the Northern Great Basin and remaining progressive. Any further digging, strengthening, or westward solution will likely result in more impacts if it were to come to fruition. Marine (Today through Saturday) Issued at 926am PDT Monday May 12 2025 A cold front continues to work across the area which will freshen westerly breezes today. The main line of light rain has moved through, with isolated to scattered showers being possible behind it. Thunderstorm chances remain minimal, though an isolated rumble of thunder or two are possible through the morning and early afternoon. Hazardous marine conditions are expected through the week with rough seas and gale force gusts expected. NOAA San Francisco Bay Area Office: Watches - Warnings - Advisories CA...None.
