...New SYNOPSIS, SHORT TERM, LONG TERM, AVIATION, MARINE...

.SYNOPSIS...
Issued at 1113 AM PDT Thu Jun 27 2024

Pleasant temperatures into the weekend. Pattern change causes a
warm up early next week, with monitoring potential excessive heat
for the second half of next week.

&&

.SHORT TERM...
(This afternoon through Friday)
Issued at 1113 AM PDT Thu Jun 27 2024

Satellite shows clear skies across our area with some high clouds
over far west over the ocean. With a semi-zonal flow, weather
conditions will be pretty similar to yesterday with low clouds
redeveloping tonight over the ocean. With breezy onshore winds, some
of the low clouds will be pushed inland along the coast. Soon as
diurnal heating starts to take place Friday morning, most of the
clouds will erode, causing another beautiful day with clear skies.
Temperatures tonight will be mostly in the 50s across the region.
Maximum temperatures Friday will be a bit warmer than today but
still around normal for this time of year. The maximum temperatures
near the coastal areas will see high 50s to mid 60s. Inland areas
will see mid 70s to upper 80s, with higher terrains seeing mid
90s.

.LONG TERM...
(Friday night through next Wednesday)
Issued at 1113 AM PDT Thu Jun 27 2024

Weather conditions remain pretty consistent through the weekend into
the first half of next week. Ensemble shows that the trough will
continues to deepen, which will bring a continuation of coastal
stratus that develop overnight that can linger longer in the
mornings. Going into the weekend, max temperatures increase a bit to
mid 80s to mid 90s inland, and mostly 60s to low 70s along the
coast. Overnight temperatures will see mostly 50s to low 60s. Monday
will be the start of a pattern shift, where a high pressure system
building over the ocean, will cause temperatures to increase. NBM
continues to show max temperatures in the 90s inland with possible
triple digits for higher terrains starting Monday into Wednesday.
Coastal areas will also be impacted with temperatures in the mid to
upper 70s. Climate Prediction Center 6-10 temperature outlook also
highlights our area in 40-60% chance for above normal temperatures.
As we are still 4+ days out from the warm-up, stay tuned for any
updates and additional details about the weather conditions as we
head into the 4th of July weekend.

.AVIATION...
(18Z TAFS)
Issued at 1113 AM PDT Thu Jun 27 2024

VFR lasts into the night. Winds increase into the afternoon with
strong and gusty winds at SFO and along the coast, while other areas
stay moderate to breezy. Winds reduce into the night as IFR/MVFR
CIGs move over the coast and Monterey Bay terminals. These CIGS look
to last into Friday afternoon as widespread moderate to breezy

Vicinity of SFO...VFR through the TAF period. Winds increase this
afternoon with gusts peaking around 28 kts. These winds last into
the night, reducing, but staying breezy for much of the night.
Breezes reduce into early Friday but pick up again that afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR lasts into the night. Moderate to
breezy westerly winds build this afternoon, with slightly stronger
winds expected at the immediate coast. Winds reduce the early night
as IFR CIGS move inland and fill over MRY, with SNS filling later
into the night.

.MARINE...
(Today through Tuesday)
Issued at 1113 AM PDT Thu Jun 27 2024

  Fresh northwesterly winds continue into the weekend. Building
surface high pressure over the Eastern Pacific Ocean will move
east, tightening the pressure gradient and thus increasing the
winds. Strong northwesterly breezes with gusts approaching gale
force will prevail for most of the period. Wind is the main driver
for the Small Craft Advisories; however, significant wave heights
begin to build to 10-12 feet towards the end of the period.

.MTR WATCHES/WARNINGS/ADVISORIES...
CA...None.
PZ...Small Craft Advisory until 3 AM PDT Saturday for Pigeon Pt to Pt
     Pinos 10-60 NM-Pt Arena to Pt Reyes 0-10 nm-Pt Arena to Pt
     Reyes 10-60 NM.

     Small Craft Advisory until 3 AM PDT Friday for Pigeon Pt to Pt
