.SYNOPSIS...
Issued at 102 PM PDT Sat May 24 2025

Mostly quiet weather pattern across the region with minor day-to-day
changes through Monday. A warming trend will kick off Tuesday and
warm to above seasonal averages by the Friday of the upcoming
week.

&&

.SHORT TERM...
(This evening through Sunday)
Issued at 102 PM PDT Sat May 24 2025

A weak upper level trough continues to exit the region today. This
will allow temperatures this afternoon to warm into the upper 50s to
lower 60s near the coast where low clouds appear to have the
greatest probability of hanging around much of the day. Meanwhile,
the interior will warm into the mid/upper 70s to lower 80s. Breezy
west to northwest winds are expected this afternoon with gusts up to
35 mph along the coast and in the NW-SE oriented valleys.

Widespread low clouds look to return tonight and penetrate into the
coastal adjacent valleys as a solid marine layer remains in place.
Temperatures overnight will range from the upper 40s to low 50s.
Tomorrow, expect similar afternoon winds and temperatures as we have
today.

.LONG TERM...
(Sunday night through next Friday)
Issued at 102 PM PDT Sat May 24 2025

An upper level ridge will then build across the region beginning
Wednesday and last through next weekend. However, a cut-off low is
forecast to develop within the broader ridge and move towards Baja
California late in the upcoming week. The exact track/placement of
the cut-off low may impact temperatures and overall weather across
our region in the upcoming week. However, the overall trend is for
interior temperatures to warm to as much as 15 degrees above average
by Friday. Meanwhile, temperatures look to continue to be near
normal for coastal locations. Thus, the warmest interior locations
are likely to reach Moderate HeatRisk on Friday. This is advertised
with high confidence based on ensemble guidance and cluster
analysis. With some uncertainty with the position of the cut-off
low, be sure to stay tuned to the latest forecast information.

.AVIATION...
(00Z TAFS)
Issued at 459 PM PDT Sat May 24 2025

Widespread MVFR to IFR CIGs are expected to develop tonight with
some potential for LIFR conditions along the Monterey Peninsula and
HAF. Moderate confidence that CIGs will stay MVFR with some ensemble
models showing lower CIGs developing overnight. Current thinking is
that CIGs will build back in early this evening with satellite
showing a decent stratus field just offshore. There is some
potential for visibilities to drop overnight but confidence is low
that fog will develop. CIGs clear late tomorrow morning with VFR
conditions prevailing for much of tomorrow afternoon. Moderate winds
will ease overnight before strengthening again during the day
tomorrow.

Vicinity of SFO... Patchy MVFR CIGs continue over SFO with more
widespread MVFR CIGs to build back in this evening. Breezy westerly
winds continue through the evening before easing slightly overnight.
Low confidence that CIGs will become IFR and SFO overnight but LAMP
probability guidance does support a 40-50% chance of this occurring
from 09-15Z. CIGs will dissipate by late tomorrow morning with gusty
westerly winds to redevelop.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...MVFR CIGs persist through early tomorrow
afternoon when CIGs will briefly clear. Satellite shows some
clearing in the vicinity of SNS but onshore flow looks to be strong
enough to keep stratus training over SNS through the remainder of
the afternoon. Low to moderate confidence that LIFR conditions will
develop overnight with the highest chances from 11Z to 15Z. Moderate
westerly winds are expected to continue through this evening before
easing overnight and strengthening again during the day tomorrow.

.MARINE...
(Tonight through next Thursday)
Issued at 459 PM PDT Sat May 24 2025

Breezy to gusty northwest winds will continue through Memorial
Day weekend. Expect hazardous marine conditions across the waters
through the weekend as rough and hazardous seas linger. Conditions
temporarily improve Sunday into Monday across most of the coastal
waters before another round of widespread rough seas and breezy to
gusty winds return midday Monday.
