Rain showers and isolated thunderstorms will continue into this
evening before gradually tapering off Wednesday morning. Dry
conditions are expected for the remainder of this week with
unsettled conditions returning by Saturday night. This weekend`s
rain appears to be beneficial and not overly impactful.

.SHORT TERM...
(This evening through Wednesday)
Issued at 132 PM PST Tue Feb 20 2024

Scattered to widespread rain showers and thunderstorms will continue
throughout the evening as a low pressure system is deepens off of
the Pacific Northwest coast. This feature will shift northeast and
eventually move become a cut-off low off of the British
Columbia/Pacific Northwest coasts. Any thunderstorms that do develop
will be capable of producing brief heavy downpours, lightning, small
hail, and a few stronger wind gusts. Rain will begin to tapper off
overnight with lingering showers likely to persist over the Bay Area
into Wednesday morning.

&&

.LONG TERM...
(Wednesday night through next Monday)
Issued at 132 PM PST Tue Feb 20 2024

Dry conditions and a gradual warming trend are looking more likely
to persist into Saturday. Unsettled conditions return region-wide by
Saturday night, yet most rainfall will be "beneficial" and is not
expected to result in any widespread flooding concerns. Temperatures
trend colder for early next week with highs in the upper 50s to
lower 60s and lows in the upper 30s to upper 40s.

.AVIATION...
(00Z TAFS)
Issued at 358 PM PST Tue Feb 20 2024

Rain showers continue to push through the region at this time,
bringing MVFR conditions for many terminals as CIGs and visibilities
lower. However, into the nighttime hours, expect showers to become
more scattered in nature. MVFR CIGs will persist through the
nighttime hours for many terminals as clouds continue to advect
through the region. Winds overnight will be generally light and
S/SW. Into the daytime of Wednesday, winds become more westerly in
direction, and increase to generally 10 knots or below.


Vicinity of SFO...The main band of rain showers has largely passed,
though scattered showers can still be expected to impact the
terminals through at least the morning of Wednesday. MVFR conditions
are likely to improve to VFR in the early evening today as the last
of the main rain band exits the region. Confidence on maintaining
VFR through the overnight hours is moderate, as passing showers
could reduce visibilities at times. Winds weaken overnight to around
7 knots out of the S/SW, but slowly turn to become more onshore into
the afternoon of Wednesday around 9 knots.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Monterey Bay terminals are likely to see
MVFR CIGs develop into the early morning of Wednesday. Come the late
morning, and conditions are expected to improve to VFR once again as
shower activity diminishes and clouds push out of the region.
Winds light overnight tonight out of the S. Winds become onshore
Wednesday afternoon and breezy around 10 knots.

.MARINE...
(Tonight through next Sunday)
Issued at 358 PM PST Tue Feb 20 2024

Scattered linger into the night before a return to fair and calm
weather Wednesday. Wave heights will continue to decrease through
the end of the work week. Additional, less impactful showers
arrive early Friday with a moderate northwest swell.
