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.

High clouds are making stratus harder to discern on satellite but the general trend of stratus persisting along the coast and SF Bay continues. Low confidence that stratus will reach STS and APC. Confidence is higher that stratus will filter into the SF Bay and impact OAK but guidance continues to maintain a "donut hole" around SFO, keeping it VFR through the night. IFR to LIFR conditions are expected at MRY and SNS with stratus already present at both sites. Visibilities are expected to drop but should stay between 2-4SM. The HRRR continues to call for fog along the SF Bay shoreline and Monterey Peninsula but this is a much more aggressive solution than those undertaken by the MOS and LAMP. Given the higher marine layer, not expecting widespread fog tonight but we may see some patchy fog along the coast. Gusty onshore winds are expected tomorrow with widespread gusts between 20-30 knots expected. SFO may see gusts in excess of 30 knots during the afternoon/evening.
Vicinity of SFO, VFR. Guidance shows a "donut hole" over SFO with stratus on all sides of the airport but not over it. There is some potential for clouds to fill in overnight with LAMP guidance shows a low chance (< 30%) of MVFR conditions from 10-13Z. Confidence remains low in this scenario. Gusty onshore winds are expected during the afternoon/evening. Gusts look to peak around 30 knots with gusts potentially up to 35 knots in the late afternoon/evening.
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, IFR to LIFR overnight. IFR CIGs gradually lower and become LIFR overnight with visibility dropping to 2-3SM. Not currently expecting fog given the deeper marine layer but there is a low potential for fog to develop in the early morning hours. CIGs clear mid to late morning before MVFR-IFR CIGs return during the evening. Gusty onshore winds are expected during the afternoon/evening with gusts between 20 to 25 knots possible.

Hazardous conditions for small crafts continue through this weekend. Northwest winds continue to increase overnight with widespread strong winds across the coastal waters by early Wednesday. Gale force gusts are expected by Wednesday afternoon across coastal jet regions and portions of the outer waters. Seas build with wave heights between 10 to 14 feet expected late week. Moderate seas prevail through Wednesday before becoming rough Thursday into the weekend. Winds decrease and seas ease heading into the next work week.
