It's only the second day into June and we're seeing classic June Gloom conditions across the Bay Area and Central Coast. Solid intrusion of morning stratus rolled back to the coast this afternoon. Despite some afternoon sunshine, inland areas that felt the marine influence this morning are still struggling to rebound temp wise. Did an afternoon forecast update to nudge temps down for inland valleys. Coastal areas on the other hand are right on track with cool and lingering clouds.
While we'll still seem a marine layer intrusion, especially early tonight, the foot print for stratus Wednesday AM will be different than what we saw this morning. A weak/dry cold front will approach from the north overnight. As such, we'll see N-S pressure gradient and winds increase. Therefore, the marine layer will be more broken up Wednesday AM. Better mixing will also lead to little to no dense fog.
Temperatures on Wednesday will warm up a little bit over Tuesday's temps, but still be tempered by onshore flow and some marine layer influence. 60s/70s coast and bays with 80s/mid 90s interior.

Marine layer still lingers, but warming airmass overhead will continue a subtle warming trend of an additional 3-5 degrees.
A notable shift in the longwave pattern will bring a marked change with regards to our sensible weather for the rest of the Long Term. Friday will be a transition day with temperatures and overall weather with moderating conditions. Saturday will be a drop in temperatures across the region. A deep upper low for this time of year will swing into the PacNW. The associated trough will move into CA Friday into Saturday. Overall troughing pattern will persist through the rest of the forecast period. Night/Morning marine layer will reform with seasonably cool temps. Occasional drizzle will be possible along the immediate. In fact, longer range ensembles are hinting as a few showers by next Tuesday.
(00z TAFS) Issued at 443 PM PDT Tue Jun 2 2026
More widespread MVFR-IFR conditions are expected tonight with most sites (excluding SJC and LVK) to see overcast conditions. IFR-LIFR conditions are expected along the coast. Decreases to 4-5SM visibilities are expected overnight but confidence is low that fog will develop. If fog does develop, it would be along the coast (MRY and SNS) with a much lower chance across the interior. Gusty onshore winds return during the afternoon/evening with widespread gusts to around 25-30 knots.
Vicinity of SFO, VFR through the TAF period. Ensemble guidance shows stratus pushing through the Golden Gate gap but largely staying away from SFO. The stratus looks to form a "donut hole" around the airport which should keep it VFR tonight. Winds ease slightly overnight before gusts strengthen tomorrow afternoon/evening. Gusts to around 30 knots are expected with some potential for gusts up to 35 knots during the late afternoon.
SFO Bridge Approach, Overcast conditions with MVFR-IFR ceilings are expected across the Bay tonight while VFR conditions prevail at SFO. CIGs clear by late morning with gusty winds expected during the day.
Monterey Bay Terminals, Stratus is pushing inland on satellite with IFR to LIFR ceilings expected overnight. Visibilities drop to 2-3SM during the early morning with a low potential for fog to develop. Confidence is lower that fog will develop tonight given a deeper marine layer and lower probabilistic chances. Winds ease overnight before gustier onshore winds return during the afternoon/evening. Gusts between 20 to 25 knots are expected at MRY and SNS tomorrow.
(tonight through next Sunday) Issued at 443 PM PDT Tue Jun 2 2026
Stronger northwest winds are arriving to the northern waters, bringing hazardous conditions for small craft. These winds will spread south, leading to widespread small craft advisories into the night. Winds will continue to build into Wednesday resulting in gale force gusts across the northern outer waters and along the coastal jet regions. Moderate seas will prevail through Wednesday before building to become rough Thursday into the weekend. Winds look to finally ease into the next work week.
