...New AVIATION...

.SYNOPSIS...
Issued at 136 PM PST Tue Nov 26 2024

Soggy conditions will persist through the remainder of today into
early Wednesday, especially across the Central Coast. Drier and
cooler air sets in behind a weak cold front pushing south through
our area by early tomorrow morning. Overnight lows will drop into
the 30s for many locations beginning Wednesday night and persisting
into the weekend.

&&

.UPDATE...
Issued at 840 PM PST Tue Nov 26 2024

No changes are required to the forecast this evening. Radar shows
a few light returns over the southern portion of the Central
Coast, though precip might not be making it to the surface.
Satellite shows some patchy fog and/or stratus beneath the high
cloud for portions of the North Bay and Central Coast. Further fog
and stratus development would be dependent on breaks in the high
clouds or clearing.

.SHORT TERM...
(This evening through Wednesday)
Issued at 136 PM PST Tue Nov 26 2024

A steady stream of clouds with occasional light rain/drizzle will
persist through the remainder of today and this evening across the
Central Coast, as a cooler and drier airmass works its way south
from NorCal. The North Bay and Bay Area have begun to see more
sunshine mix in with the clouds as the drier air begins to intrude
from the north early this afternoon. Rain totals since sunrise are
all under a tenth of an inch. Coastal ranges across Big Sur and the
Santa Lucia`s may see up to a quarter of an inch of additional
rainfall for the remainder of today and tonight, maybe a few
hundredths for lower lying spots and interior valleys. Overnight
lows tonight will be about 5-10 degrees cooler than what we saw
early this morning. With less cloud cover tomorrow, we`ll see
highs increase only slightly from today, mainly in the low/mid
60s, upper 50s along the coast.

.LONG TERM...
(Wednesday night through next Monday)
Issued at 136 PM PST Tue Nov 26 2024

With drier air and mostly clear skies tomorrow night into early
Thursday morning, expect to see temperatures drop another 3-5
degrees for when you wake up Thanksgiving morning. Some areas that
saw heavy rain over the past week may see some radiational fog
develop as well. With the colder temperatures, also likely to see
frost develop across lower lying interior locations and valleys.
Synoptic scale ridging begins to gradually build across the west
over the weekend, however a weak upper low attempts to undercut the
ridge near our latitude and points south on Saturday afternoon
keeping highs on Saturday similar to Friday. By Sunday,
incremental H50 increases and thickness values take hold under
mostly sunny skies, resulting in gradual warming for the end of
the weekend into the beginning of next week.

.AVIATION...
(06Z TAFS)
Issued at 923 PM PST Tue Nov 26 2024

Mid-high level clouds continue to stream over the region making it
hard to discern low clouds at the surface. For example, KSJC
developed a MVFR cig, which is more pessimistic than previous
taf. On the flip side, Monterey Bay terminals are looking more
optimistic than previous tafs as conditions are now VFR. The
tricky/low conf portion of the forecast tonight will be fog. KSTS
had brief fog earlier and KOAK is reporting nearby fog.

Vicinity of SFO...Light winds will VFR conditions. Mid-high level
clouds. Still expecting NE winds overnight switching NW Wednesday
afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR conditions.

.MARINE...
(Today through Sunday)
Issued at 830 PM PST Tue Nov 26 2024


A weak front will continue to exit the region to the south
tonight. In its wake light to moderate northerly winds will
develop over the coastal waters. A long period southerly swell
will continue to fill in over the waters tonight and continue
into Thursday night.
