...New AVIATION, MARINE...
.SYNOPSIS...
Issued at 352 AM PST Sat Nov 23 2024
Wet weather continues through mid next week, with post frontal
showers forecast across the region today. After many days of wet
weather, drier weather may try to make an appearance mid to late
next week.
&&
.SHORT TERM...
(Today and tonight)
Issued at 352 AM PST Sat Nov 23 2024
We are moving into a post frontal environment today, which means
showers are forecast to linger across the region. The good news is
that we were able to cancel the following products: the Wind
Advisory, the Flood Watch for the North Bay, the Flood Warning for
south central Sonoma County, and finally the Marin, Sonoma, and Napa
Flood Advisory. Flood Warnings remain in place for central Sonoma
County and on the Russian River at Johnsons Beach at Guerneville. If
traveling in the North Bay today, be on the look out for lingering
flooding and heed any road closure notifications.
In terms of highs, most areas will generally be in the upper 50s to
low 60s, though higher elevations range from the mid 40s to mid 50s.
New rainfall amounts, should a shower pass over should around or
below 0.25". Tonight, chilly temperatures in the 40s will be
realized for much of the region with higher elevations falling into
the mid to upper 30s.
&&
.LONG TERM...
(Sunday through Friday)
Issued at 352 AM PST Sat Nov 23 2024
Cluster analysis shows an upper level low working its way to and
across the PacNW through the early portion of the work week.
Scattered showers are forecast from Sunday through Wednesday, with
models varying some on timing and placement of these batches of
rain. Total rainfall amounts for this period generally remain the
same, around 0.5 inches to 2.0 inches for the Bay Area, 1.0 to 2.0
inches for Central Coast, and 2.0 to 3.0 inches for the Santa
Lucias. Cluster analysis continues to both ridging over the eastern
Pacific and some troughing as well. Current thinking is there should
be at least brief period of dry weather late Wednesday into Friday;
however, confidence remains a bit low on that due to the differences
in the clusters and models. Looking beyond in the 6-10 day outlook
from the CPC, we look to be near normal temperatures and have below
normal chances for precipitation.

.AVIATION...
(18Z TAFS)
Issued at 1008 AM PST Sat Nov 23 2024
Scattered lower and mid-level cloud cover continues to affect the
region with some lingering light showers. As these showers pass,
expect moderate west winds building for much of the area. Expect
stronger gusts along the coast and at SFO in the mid afternoon with
these elevated winds lasting into the night before reducing. Low
cloud cover also reduces through the afternoon, with VFR expected
through the remainder of the TAF period. South and south east winds
affect some of the terminals overnight and into Sunday morning ahead
of a weak rain band entering the area late Sunday morning and
lasting through that afternoon.
Vicinity of SFO...VFR through the TAF period. Showers are exiting
the area with scattered to broken mid- level clouds lingering
through the night. Light southerly winds become more moderate and
westerly into the afternoon. These winds reduce overnight. Expect
additional rain chances and breezy southerly winds into late Sunday
morning. These winds and rains exit later that afternoon.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...VFR through the TAF period. Expect moderate
west winds to build this afternoon and last into the night. Winds
become light into the night with some passing showers. Expect
moderate southeast winds to build early sunday morning.
&&
.MARINE...
(Today through Thursday)
Issued at 1008 AM PST Sat Nov 23 2024
Winds continue to decrease with only lingering scattered showers
moving through the waters. Wave heights will also continue to
decrease a well. Seas and winds rebuild late tonight into early
next week as another storm approaches the region. Winds will
initially be strongest north of Point Reyes.
