KEY MESSAGES

- Slightly above normal to seasonal temperatures through the week

- Dry weather through 7 day outlook; potential for light rain beginning of April

SHORT TERM

Issued at 1135 PM PDT Sun Mar 22 2026 (Tonight through Tuesday)

Upper level ridging gradually rebuilds on Monday with above normal temperatures continuing. High temperatures will be in the upper 70s to low 80s across the interior with 60s to 70s along the coastline. The warmest areas will be in the interior Central Coast where high temperatures will reach the mid to upper 80s. High temperatures are running 10-15 degrees above normal which is cooler than the 20-30 degrees above normal that we saw last week. One of the reasons for this difference is that the upper level ridge is weaker with heights peaking around 5850 meters over the Bay Area (compared to over 5900 meters we saw last week). The center of the ridge is located to our south over the desert southwest. We can expect temperatures to cool down overnight with morning lows on Monday and Tuesday in the upper 40s to mid 50s. Minor HeatRisk is forecast across the region through the entire week which primarily impacts those who are extremely sensitive to heat. Guidance is showing some potential for a shallow 500-750 ft marine layer developing tonight but confidence is on the lower end given the rebuilding ridge.

AVIATION

(06Z TAFS) Issued at 933 PM PDT Sun Mar 22 2026

Currently VFR at all terminals with high clouds streaming in overhead. High confidence on VFR through the TAF period. Low probability for sub-VFR conditions returning to the terminals tonight with the relatively greatest potential at HAF, MRY, and SNS. Onshore winds will prevail. Haze will reduce slant range visibilities.

Vicinity of SFO...Currently VFR with westerly flow. High confidence in VFR through the TAF period. Westerly winds will prevail.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR with southwesterly flow at MRY and VFR with northwesterly flow at SNS. Low confidence on the return of IFR conditions to the terminals tonight; if they do return, it will likely be brief and/or intermittent in the 12Z-16Z time frame. Onshore winds will prevail.

MARINE

(Tonight through next Saturday) Issued at 933 PM PDT Sun Mar 22 2026

Strong northerly winds will slowly begin to diminish tonight with moderate to fresh northwesterly breezes prevailing Monday and Tuesday. Widespread hazardous marine conditions return Wednesday with strong to near gale northerly breezes and rough to very rough seas.
