Dry weather conditions are forecast for the remainder of the day in wake of the overnight/early morning frontal passage. Cooler air advecting in from the north will keep temperatures near seasonal averages this afternoon under mostly sunny sky conditions. Temperatures will range from the mid to upper 50s along northwest facing coastal locations to the mid to upper 60s across the interior this afternoon.
Overnight, temperatures will cool into the upper 30s to lower 40s across the interior. However, offshore flow (especially in the mountains and hills) will return as the center of the mid/upper level low pushes into the Intermountain West. North-northeast winds with gusts of 40 to 55 mph in the North Bay Interior Mountains with gusts of 30 to 45 mph in the East Bay Hills, Eastern Santa Clara Hills, and Santa Cruz Mountains. So, less confidence for fog development in the interior valleys overnight.
Friday we will see a warming trend return regionwide as temperatures warm 5-10 degrees above seasonal averages as high pressure over the eastern Pacific nudges eastward. In addition, stronger winds in the higher elevations will prevail on Friday aiding in the warming trend with afternoon maximum temperatures reaching the low to upper 60s near the coast and low to upper 70s across the interior and south- southwest facing coastal locations (such as the Santa Cruz region).

High pressure will continue to build across the region this weekend with temperatures reaching 5-15 degrees above average (up to 20 in the warmer interior spots). This is as 850mb temperatures approach 12-15 degrees C. Offshore winds will also persist through the weekend, especially in the aforementioned locations, yet are forecast to be weaker than tonight/Friday morning.
As the high pressure begins to shift eastward, temperatures are forecast to cool slightly early next week. There is the potential for a mid/upper level cut off low pressure system to approach from the west bringing cooler and unsettled weather conditions back to the region by the middle of the upcoming week. However, at this time, the greatest probability for rainfall is across the North Bay and coastal ranges where there is 15-25% probability of reaching or exceeding 0.25" of rainfall ending 5 PM Wednesday (next week). Therefore, no flooding or major impacts are expected.
(06z TAFS) Issued at 950 PM PDT Thu Apr 2 2026
High confidence of VFR through the TAF period with possible high clouds developing after midnight. Moderate northwest winds will diminish through the next couple of hours, with LLWS concerns developing after midnight in the interior valleys as surface winds decouple from winds aloft. At APC, high resolution models depict some mountain wave energy making it to the valley floor, resulting in gusts as high as 18 kt between 12-18Z. Considered keeping sustained wind speeds low to maintain the LLWS group within the forecast, but opted to prioritize reflecting increased wind speeds at the surface. For Friday, interior regions will see breezy north to northeast winds, especially in the morning hours, with the potential for strong gusts in favored locations. Elsewhere, a gentle to moderate northwest flow develops in the afternoon.
Vicinity of SFO, High confidence of VFR through the TAF period with possible high clouds overnight through Friday. Moderate and west winds persist through the late evening hours, with light winds turning offshore overnight before northwesterly breezes return late Friday afternoon, diminishing in the evening.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, High confidence of VFR through the TAF period with possible high clouds overnight through Friday. Light drainage winds will persist through Friday morning. At MRY, gentle winds will gradually turn from the northeast to the northwest through the late morning and afternoon hours on Friday, with SNS seeing a resumption of the northwest flow late Friday afternoon. Winds become light again late Friday evening.
(tonight through next Wednesday) Issued at 950 PM PDT Thu Apr 2 2026
Fresh to strong breezes persist over the coastal waters through the night into Friday, resulting in hazardous conditions for small craft. Northerly breezes diminish and seas abate by the weekend, with slight to moderate seas through the middle of the next week.
