KEY MESSAGES

Updated at 1224 PM PDT Mon May 25 2026

- Cooler Conditions Continue into Tuesday

- Cloudy and drizzly to start Tuesday with building winds.

- Widespread warming and drying starts Wednesday and continues into the weekend.

SHORT TERM

Issued at 1224 PM PDT Mon May 25 2026 (This evening through Tuesday)

The marine layer continues to stay strong with the day starting off with nearly widespread lower clouds. A good amount of drizzle has been reported across the North Bay, but chances have reduced into the late morning. Higher clouds are also moving into the area, which could limit the erosion of the lower clouds, leading to cooler conditions. Expect the coast to remain cool 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 in southern Monterey Co.

Overnight will begin the next pattern change as a cold front begins to pass through the area a low pressure following close behind. This will cause most of the region to see the coolest high temperatures and cloudiest skies of the forecast. The rush of cooler air along the front will off good chances for drizzle across much of the Bay Area and Central Coast, with the best chances being along coastal peaks. While overall precip chances look good, the overall totals look to stay below just a few hundredths of an inch. 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 forecast continues to show 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.

LONG TERM

Issued at 1224 PM PDT Mon May 25 2026 (Tuesday night through next Sunday)

Cloud cover erodes Tuesday evening as northerly winds build across the region in the post-fontal environment and the parent low pressure pushes east. Winds decrease into the night, but remain northerly. The drier airmass arriving to the region will allow for widespread lows into the 40s for Wednesday Morning, making it the coolest morning of the forecast. Models hint at a weak marine layer reforming as winds reduce, but it looks to not be as moisture rich as the last few days and barely moves inland.

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. High temperatures see a notable rebound for Wednesday as skies remain on the clearer side, with temperatures steadily warming into the weekend. However, the weekend itself has a wide range of potential pattern change across models and ensembles. While some keep the warming trend and offshore flow due to modest ridging, others hint at a more zonal (west to east) flow developing and pushing onshore flow at the surface. The current forecast leans on the continued warming trend model outputs, but that can change quite a bit as new model runs publish and higher resolution models come into range.

AVIATION

(06Z TAFS) Issued at 948 PM PDT Mon May 25 2026

A cold front is expected to move through the Bay Area and Central Coast tonight bringing ceilings that are on the border of MVFR/VFR. Moderate confidence that CIGs will continue to fluctuate between MVFR and VFR through at least 10Z in the Bay Area and 13/14Z in the Central Coast. CIGs generally clear out after frontal passage but winds will strengthen. Gusts peak between 25 to 35 knots tomorrow with winds out of the northwest. Gusts start to ease towards the end of the TAF period but will largely remain gusty into Tuesday night. Drizzle is likely along the coast again tonight (potentially reaching HAF, MRY, SNS) with models showing some potential for light rain as cold frontal passage occurs tonight.

Vicinity of SFO...CIGs stay on the MVFR/VFR border through 10Z with temporary fluctuations in CIG height up and down. Gusts increase after cold frontal passage early Tuesday morning with 30+ knot gusts expected during the day tomorrow. Winds ease slightly tomorrow night through the end of the TAF period but largely remain gusty.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...CIGs are fluctuating between MVFR and VFR with fluctuations to continue occurring through cold frontal passage (approx. 13-15Z). Gusts strengthen during the day with gusts peaking between 25-30 knots. Winds start to ease towards the end of the TAF period but remain gusty overall. Guidance shows some potential for stratus to return as early as 03Z with the potential for MVFR CIGs increasing between 03-06Z.

MARINE

(Tonight through next Sunday) Issued at 948 PM PDT Mon May 25 2026

West to northwest breeze increases overnight due to cold frontal passage with widespread fresh to strong gusts expected over the waters. Winds shift northwesterly and continue to increase Tuesday into Wednesday. This results in strong to near gale force winds across the outer waters, gale force winds across the inner waters, and fresh to strong winds across the San Francisco Bay. Rough seas build to between 12 to 15 feet Tuesday into late week.
