Short Term

, Issued at 1223 AM PST Wed Feb 25 2026 (Today and tonight)

Scattered to widespread showers linger across topographically favored regions of the Bay Area and into Santa Cruz County, the remnants of a moisture plume impacting the state. Shower coverage is expected to diminish through the morning hours with isolated showers possible across terrain-favored areas of the South Bay and Central Coast this afternoon. Additional rainfall totals are nothing to write home about. At best, around a tenth to a quarter of an inch in the southeast-facing coastal slopes from Marin County down through western Santa Cruz County, in addition to the Berkeley Hills. In addition, areas of mist and fog are possible this morning in the wake of the rainfall, with the focus on the valleys of the North Bay, South Bay, and interior East Bay. Otherwise, today should be much drier, if muggier, and kick off a warming trend that will continue into the next few days, as high temperatures range from the upper 50s to lower 60s in the Bay Area Pacific coastline, to the middle 60s into the lower 70s in the interior valleys and Monterey Bay region, and the lower to middle 70s in the Central Coast valleys.

Long Term

..issued at 1223 AM PST Wed Feb 25 2026 (Thursday through Tuesday)

Dry and warm conditions continue through the next few days with the warmest conditions expected on Friday, when highs range from the middle to upper 60s in the Bay Area Pacific coast to the middle to upper 70s in the interior valleys.

The approach of a cut off low on Sunday and Monday will interrupt this warming trend, with the low center expected to pass to the north near Cape Mendocino and the northern tier of the state. As the previous forecaster noted, light showers are possible but no model output indicates anything meaningful in the region. Even the 95th percentile rainfall totals from the NBM keeps maximum 24-hour rain totals over the coastal ranges at a little over half an inch from Sunday at 4 PM to Monday at the same time. Or to put it in other words, there is only a 5% chance that the coastal ranges will see rain totals over half an inch within a 24-hour period ending Monday afternoon. Longer range outlooks continue to lack support for more impactful storms but ensemble mean output fields do suggest the possibility for a somewhat active pattern across the West Coast.

(12z TAFS) Issued at 331 AM PST Wed Feb 25 2026

Currently a mixed bag of LIFR-VFR at the terminals. Light rain shower activity will continue to diminish through the morning. Remnant low-level moisture will support low ceilings/visibilities this morning and again tonight with MVFR conditions likely prevailing through the TAF period. Light and diurnal winds will prevail.

Vicinity of SFO, Currently MVFR with light southeasterly flow. Moderate confidence on MVFR conditions prevailing through the TAF period. Winds will be light and diurnal.

SFO Bridge Approach, Similar to SFO.

Monterey Bay Terminals, Currently LIFR with easterly flow at MRY and VFR with easterly flow at SNS. SNS will likely deteriorate to at least MVFR this morning with sub-VFR conditions prevailing through the TAF period. Light and diurnal winds will prevail.
