KEY MESSAGES

Issued at 1107 AM PDT Sun May 24 2026

- Cool temperatures through Memorial Day Weekend and into the work week

- Breezy, drizzly, and cool Tuesday ahead of warming and drying conditions for the rest of the forecast.

SHORT TERM

Issued at 1107 AM PDT Sun May 24 2026 (This afternoon through Monday)

A strong marine layer and good onshore flow lead to another morning of cloudy conditions for most of the area. The influence of a large eddy off the coast of Sonoma Co may complicate clearing times, otherwise a similar set up as yesterday.

Highs today will range from the 50s along the coast, 60s for areas more inland, the low to 70s for the more interior areas, and only a few spots in the far interior breaking 80 degrees today.

The deep and expanded marine layer continues to keep humidities high for much of the area. This will really come into play overnight, keeping most of the overnight lows in the 50s and upper 40s, with only the far interior falling into the mid 40s.

The marine layer looks to deepen slightly into the night and will call for a stronger inland overnight and into Memorial Day, leading to widespread cloud cover and fair chances for drizzle. This will also cause slower clearing for the interior, and the potential for little to no clearing along the coast. Expect cool coastal conditions under cloudy skies with highs in the 50s. Then the areas slightly inland will hover around the mid to lower 60s, and the far interior will be in the 70s with possibly one or two spots breaking 80 degrees.

LONG TERM

Issued at 1107 AM PDT Sun May 24 2026 (Monday night through next Saturday)

A cold front will pass through the area early Tuesday with a low pressure following close behind. This will cause most of the region to see the coolest high temperatures of the forecast. The rush of even cooler air meeting with the already moist environment of the marine layer will cause good chances for drizzle across much of the Bay Area and Central Coast. Winds will be breezy and gusty across much of the CWA during this pattern change, with the higher elevations and favored gaps and passes seeing chances for gusts peaking around 45 mph. The national blend of models shows the front exiting the North Bay early enough in day and northerly dry winds around the low for some slight and isolated warming compared to previous days, while the rest of the region remains cool.

From there, the models are in fair agreement over another warming and drying trend as a modest offshore flow develops as the low travels to the east. Temperatures see a notable rebound for Wednesday as skies remain on the clearer side, with temperatures steadily warming into the next weekend.

AVIATION

(06Z TAFS) Issued at 919 PM PDT Sun May 24 2026

Stratus has begun to build along the coast and move farther inland over the North Bay. Expect widespread MVFR cigs at all terminals soon after midnight with a robust marine layer and steady onshore flow. Monday lifting of MVFR cigs to VFR will coincide with a notable increase of onshore winds especially for the Bay Area and South Bay terminals out ahead of a developing cold front. Expect breezy to gusty winds Monday afternoon and evening.

Vicinity of SFO...VFR is expected until midnight with MVFR cigs through the overnight hours into early afternoon, then VFR with increasing onshore winds, gusty at times through Monday evening. Winds out ahead of the advancing cold front offshore are not expected to reach AWW thresholds.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...MVFR cigs will persist overnight with higher confidence that KMRY will persist into the early afternoon, when onshore winds increase becoming breezy through the afternoon through sunset out ahead of the advancing cold front to the north with lesser influence this far south.

MARINE

(Tonight through next Saturday) Issued at 919 PM PDT Sun May 24 2026

Light west/southwest breezes continue tonight through Monday, then begin to strengthen Monday night into gusty northwest winds for Tuesday into early Wednesday. Expect building rough seas on Tuesday that persist through the end of the work week.
