.KEY MESSAGES...

above normal for Sunday into beginning of next week
- Cooler than normal temperatures may return by end of next week

.SHORT TERM...
Issued at 1201 AM PDT Sat May 30 2026
(Today and tonight)
Quiet weather with weak progressive ridging aloft overnight,
becoming primarily zonal through the day today will help lift
temperatures close to normal for this time of year. The marine layer
has returned and is well established for the remainder of the
overnight through mid-morning. Coastal areas should see the marine
layer lift by late morning with mostly sunny skies area wide for the
remainder of the afternoon and early evening. The marine layer will
once again fill back in later tonight.

.LONG TERM...
Issued at 1201 AM PDT Sat May 30 2026
(Sunday through Friday)
The progressive and relatively weak longwave synoptic pattern across
our latitude will keep the weather quiet, temperatures similar on
a day-to-day basis Sunday through Thursday with slightly above
normal temperatures and breezy diurnal wind fluctuations with
onshore flow. Confidence continues to increase for a more
organized and deeper synoptic troughing pattern for the end of
next week and beyond. Although it appears any rain would be well
to our north attm, the pattern would keep temperatures below
seasonal averages.

.AVIATION...
(12Z TAFS)
Issued at 423 AM PDT Sat May 30 2026
MVFR-IFR stratus prevails across the region and will dissipate
through the post-sunrise hours. Breezy northwest winds will develop
across the region this afternoon and evening with gusts reaching
around 15 knots. Winds will diminish in the late evening hours. High
resolution models are showing less stratus coverage overnight into
Sunday morning when compared to the current setup. This makes sense
given a developing ridge and consequent marine layer compression,
but the exact extent is hard to pin down this early.
Vicinity of SFO... MVFR ceilings through the morning with strong
gusts developing in the afternoon and evening hours, as gusts to 25
knots are expected. Not expecting gusts above 35 knots at this time.
Confidence in stratus coverage overnight through Sunday morning is
low. If it occurs, IFR-LIFR ceilings are possible in a compressed
marine layer.
SFO Bridge Approach... Similar to SFO.
Monterey Bay Terminals... Generally MVFR-IFR ceilings across the
region, dissipating through the late morning and early
afternoon hours. Breezy northwest winds develop in the afternoon and
evening. Some stratus may return to the mountains south of MRY this
evening, with moderate confidence of expansion to the rest of the
region and especially SNS through the end of the TAF period.

.MARINE...
(Today through Thursday)
Issued at 423 AM PDT Sat May 30 2026
High pressure to the north results in moderate to fresh northerly
breezes through the weekend. The strongest winds will be over the
northern outer waters. Occasional gale force gusts will occur in
the far outer waters, and the coastal jets to the south of Point
Arena and along the Big Sur Coast. Increasing winds and building
rough seas will lead to hazardous conditions over the coastal
waters through the weekend.
