...New SYNOPSIS, SHORT TERM, LONG TERM...

.SYNOPSIS...
Issued at 115 PM PDT Sat Jun 14 2025

Cool and calm conditions prevail. Warm temperatures inland, but
still near seasonal normals. Slight warming trend inland mid next
week. Dry conditions persist across high terrain, leading to
elevated grass fire danger.

&&

.SHORT TERM...
(This evening through Sunday)
Issued at 115 PM PDT Sat Jun 14 2025

Quiet conditions persist as a trough pattern set up off the West
Coast provides a deep onshore flow regime. This will keep temps
around seasonal normals - slightly below normal along the coast.
Otherwise, dry conditions continue at higher elevations
(generally above about 2,000 feet) where humidity recovery is poor
and grasses are very dry.

&&

.LONG TERM...
(Sunday night through next Friday)
Issued at 115 PM PDT Sat Jun 14 2025

Out persistent trough pattern eventually gets kicked out by a
progressive shortwave trough moving into the West Coast. Not much
worth noting regarding our weather in this case besides the
potential for some drizzle along coastal areas early next week.
Behind the shortwave, we do see a subtle warm up on tap through
Wednesday, but again nothing worth getting bent out of shape for.
We`ll basically see high temps around normal or a few degrees
above. The main hazard over the next week will be dry conditions
inland leading to elevated grass fire danger, especially above
2,000 feet where humidity recovery is poor.

.AVIATION...
(18Z TAFS)
Issued at 1027 AM PDT Sat Jun 14 2025

VFR conditions have returned to most TAF sites, with MVFR conditions
still at HAF but should scatter out here shortly. Onshore winds will
increase once again this afternoon with VFR conditions expected
through the evening. Wind ease overnight, but generally will remain
out of the west-northwest across the Bay Area terminals. There is
low confidence for IFR/MVFR ceilings to develop over the Bay Area
terminals early Sunday morning, but moderate to high confidence for
them to reach the Bay Area terminals. Low clouds that do develop
will mix out by late Sunday morning with an increase in onshore
winds by Sunday afternoon.

Vicinity of SFO...VFR. Onshore winds increase this afternoon with
gusts up to 26 KT. Low confidence for ceilings to reach SFO early
Sunday morning and have left out of the TAF at this time. However,
do have MVFR ceilings at OAK from 10Z-16Z Sunday as there is greater
potential there. Low clouds that do develop will mix out by late
Sunday morning with an increase in onshore winds by Sunday
afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR. Onshore winds increase this afternoon
and will ease late this evening. Moderate to high confidence for
IFR/MVFR ceilings to return early Sunday morning.

.MARINE...
(Today through Thursday)
Issued at 1027 AM PDT Sat Jun 14 2025

Fresh to strong northwesterly breezes, near gale force gusts, and
moderate to rough seas will prevail through Wednesday. Localized
gale force gusts will develop near the coastal jet regions of
Point Reyes and Point Sur during the afternoon and evening hours.

&&

.FIRE WEATHER...
Issued at 252 AM PDT Sat Jun 14 2025

Elevated fire weather conditions prevail through the weekend.
Night/morning marine layer will remain with cooler temperatures
and excellent humidity recovery at lower elevations. Above the
marine layer (higher hills/mts) and areas not directly impacted by
the marine layer will see moderate to poor humidity recoveries.
The lack of humidity recovery will keep finer fuels, like grasses,
drier and more susceptible to fire starts. Additionally, given the
onshore flow, winds will be gusty each afternoon/evening for inland
valleys (Salinas Valley), and gaps/passes.

The large view for the interior Central Coast shows ERC values
barely exceeding average, burn index close to seasonal averages,
and 100 hr fuel moisture slightly below seasonal averages.

Marine layer will hover 1700-2100 feet the next few days.
