...New AVIATION, MARINE...

.SYNOPSIS...
Issued at 148 PM PDT Fri Apr 26 2024

Cloud conditions with some pockets of drizzle linger on the coast
and spread inland tonight. Breezy winds arrive later this 
afternoon into tonight. Winds continue to stay breezy over the
next few days, with better afternoon clearing leading to a warming
trend over the weekend.

.SHORT TERM...
(This evening through tonight)
Issued at 142 PM PDT Fri Apr 26 2024

Similar to yesterday: Cloudy conditions continue, still some
drizzle along the coast, and breezy to gusty northwest wind this 
afternoon and evening. Expect stronger winds than yesterday 
specifically for higher peaks and along the Big Sur Coast from 
pressure gradient change as the current trough pattern pushes 
east. 

Additional drizzle chances arrive and spread inland in the 
evening with slight chances for another round of light rain 
chances on higher elevations and along the coast.

.LONG TERM...
(Saturday through Thursday)
Issued at 426 AM PDT Fri Apr 26 2024

Forecast philosophy remains unchanged from yesterday afternoon. The 
previous discussion follows:

The new upper level pattern  keeps mostly northwest onshore flow 
into the weekend. While the immediate coast will continue to 
struggle with cloud cover, most areas slightly more inland and well 
into the interior will see quicker clearing times. This will place 
most areas back into the 60s and 70s into the next work week, while 
the coast will stick to around 60 degree highs. By the late week, 
some of those more interior locations look to break into the low 80s.

Longer term models are in better agreement that the next rain maker 
may just stay well to the north of the Bay Area and Central Coast as 
the ECMWF model families have adjusted the next trough to arrive 
over Seattle rather than the Bay area.

.AVIATION...
(00Z TAFS)
Issued at 426 PM PDT Fri Apr 26 2024

Satellite shows FEW to SCT clouds shuffling through the region but 
VFR and some clear skies over the terminals. Breezy and gusty 
westerly winds will continue to linger through early evening before 
becoming moderate overnight. Breezy conditions return late Saturday 
morning/early afternoon. VFR is expected to prevail through the TAF 
period for most terminals except Monterey Bay terminals. 

Vicinity of SFO...VFR through the TAF period but a few models 
suggest MVFR returning overnight and clearing early morning, but had 
low confidence to include in TAFs at this moment and input a SCT 
group to hint at the possibility. Westerly winds will remain gusty 
through most of the early evening then diminish to moderate by 09-
10Z. 

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR through most of the TAF period but 
models show agreement of another round of MVFR conditions overnight 
with KMRY seeing ceilings as early as 02Z. Moderate confidence on 
exact timing but overall model agreement that MVFR will occur after 
08Z for both terminals. Gusty westerly winds will diminish to 
moderate overnight before becoming breezy and gusty again by 
Saturday afternoon.

.MARINE...
(Tonight through next Wednesday)
Issued at 426 PM PDT Fri Apr 26 2024

Strong northwesterly winds with gale force gusts are to be
expected  through the weekend, particularly over the coastal
waters. Light  rain will be possible over the waters today as a
result of the  passing weak cold front. Moderate period
northwesterly swell will  continue to move through the waters
through Wednesday.
