...New AVIATION, MARINE...

.SYNOPSIS...

possible each morning. Temperatures rebound late weekend and early

persist throughout late next week.

.SHORT TERM...
(Today and tonight)
Issued at 215 AM PDT Fri Apr 19 2024

A well defined marine layer is in place this morning (around 1800-
2000 ft per Fort Ord Profiler) and will support patchy drizzle in
the upslope regions this morning. Otherwise, this afternoon sunny
conditions will return to inland areas with temperatures expected to
warm into the low to mid 70s. Meanwhile, the coast remains in the
upper 50s to mid 60s under mostly cloudy conditions.

Tonight, expecting clouds to make a return back inland and become
more widespread with low temperatures in the upper 40s to lower 50s.
Again, patchy drizzle will once again be possible. Saturday will
feature slightly warmer temperatures inland, but only by a few
degrees. Wind will also be on the increase with breezy northwest
winds near the coast, in the coastal hills, and into the region`s
valleys. Looking for gusts of 25-35 mph in these areas by Saturday
afternoon.

.LONG TERM...
(Saturday through Thursday)
Issued at 215 AM PDT Fri Apr 19 2024

By Sunday and Monday, ridging dominates the pattern once again with
interior areas warming to near 80 degrees with 60s and 70s as one
gets closer to the coast. By Tuesday, a change to more unsettled
conditions return as an upper level low approaches the region. This
pattern will persist throughout late week and points to possible wet
weather during the latter half of the week. However, there is no
major concerns for flooding and may end up being widespread light
drizzle if not light rain. Temperatures also turn cooler with highs
in the upper 50s at the coast and mid-to-upper 60s inland from
Tuesday throughout late week. Stay tuned!

.AVIATION...
(18Z TAFS)
Issued at 1117 AM PDT Fri Apr 19 2024

Stratus continues to linger throughout portions of the Bay Area with
conditions ranging from VFR to MVFR-IFR. Satellite imagery shows
stratus is dissipating along the Central Coast with VFR to return
within the next hour. Satellite shows dissipating stratus in the
North Bay remains slightly more widespread but VFR conditions are
expected to return in the next 1 to 2 hours. After stratus
dissipation, VFR will prevail through the late evening/early night
with stratus and MVFR to IFR returning overnight. Light to moderate
winds primarily out of the W.

Vicinity of SFO...VFR conditions through the end of the TAF.
Guidance indicates that stratus may return between 08-16Z but
confidence was low. Stratus previously developed at SFO from 11-14Z
this morning. If persistence holds true, stratus may develop early
tomorrow morning but as of now confidence was too low to include in
TAF. Light northerly to northeasterly winds at SFO will transition
more northwesterly to westerly through the TAF period with moderate
winds to return during the afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR to MVFR-IFR overnight. Stratus
continues to linger over portions of the Central Coast with VFR
conditions to fully return at MRY and SNS within the next hour.
Stratus will return late this evening through mid tomorrow morning.
Moderate confidence given guidance and persistence that IFR
conditions will develop at MRY and SNS overnight. Guidance indicates
some potential for LIFR overnight but confidence remains low.
Primarily light to moderate winds out of the west at MRY and winds
out of the west to northwest at SNS.

&&

.MARINE...
(Today through Wednesday)
Issued at 1117 AM PDT Fri Apr 19 2024

Light to moderate breezes out of the northwest and fair weather
prevail over much of the waters through at least Saturday
afternoon. Come the evening of Saturday, northwesterly winds
increase to become strong and gusty. Swell builds into Sunday out
of the northwest as gusty conditions continue but looks to
diminish towards the middle part of the next week. Light southerly
swell continues to move through the waters this weekend and
through the next work week.
