.SHORT TERM...
Issued at 157 PM PDT Tue Jun 2 2026
(This evening through Wednesday)
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.

.LONG TERM...
Issued at 157 PM PDT Tue Jun 2 2026
(Wednesday night through next Monday)
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.

.AVIATION...
(18Z TAFS)
Issued at 131 PM PDT Tue Jun 2 2026
Most sites are seeing VFR with the exception of HAF which looks to
have some momentary breaks in MVFR CIGs, but looks to keep CIGs
through the day. Moderate to breezy winds are building across much
of the region with west to northwest winds for most areas, but south
to southwest winds in the North Bay sites. Winds will begin to
reduce into the evening and will be lighter overnight. CIGs rebuild
this evening around the Monterey Bay and along the coast, followed
by OAK into the night. Moments of IFR CIGs look to affect APC in the
late night while the Monterey Bay terminals go LIFR. Pockets of fog
and mist will be possible along the coast and potions of the North
Bay into Wednesday morning.
Vicinity of SFO...Moderate west winds with gusts up to 25 kts last
into the night before reducing.Cloud cover looks to mostly stay to
the north and west of the Terminal overnight, but will lead to
scattered clouds around 1000 ft AGL. These clouds will thin into the
mid to late morning as moderate west winds arriving
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...VFR lasts and moderate winds last into the
evening before winds weaken and IFR CIGs move over the terminals.
Winds become lighter into the late night and CIGs fall to LIFR
levels with fog and mist affecting visibilities. An otter eddy looks
to form over the Monterey Bay in the late night, causing some
movement in CIGs from the oscillation, which could lead to some
short-lived improvements to CIGs and visibilities, but clearing is
expected beyond the TAF period.

.MARINE...
(Tonight through next Sunday)
Issued at 131 PM PDT Tue Jun 2 2026
Northwesterly breezes are increasing in the northern waters,
bringing hazardous conditions for small craft by the afternoon.
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.
