...New SYNOPSIS, SHORT TERM, LONG TERM...

.SYNOPSIS...
Issued at 255 AM PDT Tue May 28 2024

Near seasonal temps inland again today with the coast remaining
cool under a well-formed marine layer. Pleasant weather continues
through the week.

&&

.SHORT TERM...
(Today and tonight)
Issued at 255 AM PDT Tue May 28 2024

Another day with temperatures right around seasonal averages
across inland areas. Coastal areas will still be under the
influence of a stout marine layer with cool temps in the upper
50s to near 60. Passing upper trough through the PacNW flattens
out our ridge a bit, putting a slight pause on the warming as we
move into the middle part of the week. Overall no major changes
to the short term period.

&&

.LONG TERM...
(Wednesday through Monday)
Issued at 255 AM PDT Tue May 28 2024

The cooling trend will be short-lived as the flattened ridge
begins to build back over the region with warming 850 mb temps and
rising 500 mb heights. Still looks like night/morning clouds with
inland afternoon sunshine will persist. The warming trend will
continue into this weekend with the warmest temps expected
Thursday and Friday. Far inland locations will reach the low 90s
by week`s end.

.AVIATION...
(06Z TAFS)
Issued at 1208 AM PDT Tue May 28 2024

Stratus will build into area terminals throughout the night, leading
to predominantly IFR/MVFR CIGs across coastal terminals. Only far
inland terminals are expected to remain VFR through the night
tonight, though a FEW low clouds may build in the mid morning of
Tuesday. Late clearing of stratus is expected, towards the late
morning. Into the afternoon, gusty onshore winds are expected, with
gusts generally in the 20-25 knot range, higher at SFO. Winds will
be slow to ease, with breezy conditions lingering through the end of
the TAF period.

Vicinity of SFO...MVFR conditions last through the late morning. At
this time, highest confidence is in an 18Z clearing, ushering in VFR
conditions as westerly winds begin to increase. Gusts will steadily
build in the afternoon, reaching up to around 30-33 knots at the
strongest. Into the late night, winds are slow to ease with gusts
above 20-25 knots persisting as night begins to fall. It is not
until the early morning of Wednesday that gusts are expected to
decrease, with sustained winds lowering to become breezy.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...LIFR/IFR conditions persist through the
late morning. Stratus expected to begin to lift and mix out towards
18Z, bringing a return of brief VFR conditions. Winds increase out
of the NW to become breezy around 15 knots, with occasional gusts
closer to the 20 knot range. Stratus returns bringing IFR/MVFR CIGs
in the early evening.

.MARINE...
(Tonight through next Saturday)
Issued at 442 PM PDT Mon May 27 2024

Breezy to gusty northwest winds continuing across the coastal
waters through the week with westerly breezes increasing each
afternoon and evening across the bays. Wave heights beginning to
increase by the middle of the work week up to 11 to 13 feet.
