.SHORT TERM...
Issued at 1215 PM PDT Wed May 27 2026
(This evening through Thursday)
We have already seen showers and an isolated thunderstorm develop
late this morning across the Eastern Santa Clara Hills and in the
Mountains of San Benito County. As daytime heating continues, we are
expecting convection to fire up in the East Bay Hills, Eastern Santa
Clara Hills, the Santa Cruz Mountains and the Central Coast (County
of Monterey/San Benito) this afternoon and evening. This is as the
atmosphere becomes more unstable with CAPE values between 100-400
J/kg. However, vertical wind profiles don't favor organized
convection, with little to no 0-6km wind shear. Therefore,
probabilities for thunderstorms remain less than 10% through the
afternoon and early evening. Any stronger cell (shower and/or
thunderstorm) that develops over any one given location has the
potential to produce 0.25"-0.50" per hour of rainfall.
The mid/upper level low will begin to retrograde back over the
Pacific tonight into early Thursday morning and begin to pull in
PWAT values of around 1.00". This will increase rain chances
offshore late tonight and then will move onshore along the Central
Coast through Thursday morning. However, with the loss of daytime
heating, the thunderstorm threat will lessen. Forecast rainfall
amounts have increased in the Santa Cruz Mountains and Santa Lucia
Range now having a greater than 60% probability of seeing more than
0.25" through Thursday afternoon (this would include rainfall from
today). These probabilities of seeing greater than 1.00" (40%-75%)
remain confined to the Santa Lucia Range.
Conditions begin to dry out from north to south during the day
Thursday as the mid/upper level low shifts further inland. However,
rain showers look to linger over the Central Coast through the early
evening.
&&
.LONG TERM...
Issued at 1215 PM PDT Wed May 27 2026
(Thursday night through next Tuesday)
Cannot rule out rain showers to linger across the North Bay late
Thursday night into early Friday morning as deeper moisture (PWAT
values approaching 1.00") move across this region. In wake of the
exiting trough, a warming and drying trend will kick off by Friday
afternoon with temperatures gradually returning to near average this
weekend as zonal flow develops over the region. Temperatures are
currently forecast to warm above seasonal averages by Sunday and
into the middle of the upcoming week.

.AVIATION...
(00Z TAFS)
Issued at 453 PM PDT Wed May 27 2026
Scattered showers and isolated thunderstorms have developed across
the Bay Area and interior Central Coast. Have added VCTS to the
APC TAF but may need to be added in to LVK and SJC as well. Breezy
onshore winds continue this afternoon before winds diminish
overnight. Widespread rain returns by early tomorrow morning and
continues through much of the TAF period. Cannot rule out isolated
thunderstorms again tomorrow afternoon/evening but confidence is
too low to include in TAFs at this time.
Vicinity of SFO...Gusty onshore winds diminish by late
evening/overnight with breezy conditions expected again tomorrow
afternoon/evening. MVFR CIGs are possible overnight but confidence
is low to moderate. Rain chances increase as early as 06Z with
more widespread rain arriving closer to 10Z. Rain chances decrease
by the afternoon with a low potential for isolated thunderstorms
in the afternoon/evening.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals... MVFR CIGs and gusty onshore winds
through this evening. Overcast conditions continue through late
tomorrow morning with winds to strengthen again during the
afternoon and evening. Rain chances increase around 03 to 06Z with
more widespread rain arriving around 10Z. Rain continues through
the end of the TAF period.
&&
.MARINE...
(Today through Monday)
Issued at 1005 AM PDT Wed May 27 2026
Northwesterly winds continue to diminish through today and
overnight into widespread gentle to moderate breezes over the
outer and inner waters. Wind gusts also become more moderate, with
the outer northern waters experiencing locally strong gusts
through Thursday morning. Rough seas with heights of 11-16 ft
continue to abate through today and become more moderate (5-9 ft)
by Friday morning. Another round of strong to near-gale force
winds are expected to develop over the weekend with building rough
seas again.
