...New AVIATION, MARINE...

.SYNOPSIS...
Issued at 154 PM PDT Tue Apr 16 2024

Warm, dry, and quiet this week as high pressure dominates. Onshore
flow and increased cloudiness late week as weak trough moves in.

&&

.SHORT TERM...
(This evening through Wednesday)
Issued at 154 PM PDT Tue Apr 16 2024

Mostly clear skies across the region, which will persist through
the next few afternoons. Wednesday looks to be near the warmest
day of the week with afternoon highs in the mid-to-upper 70s
inland, and in the 60s to near 70s along the coast. Inland valley
locations may see the 80 degree mark.

&&

.LONG TERM...
(Wednesday night through next Monday)
Issued at 154 PM PDT Tue Apr 16 2024

The long term remains mostly dry as well. Pleasant temperatures
last through the period, but many location will see a very slight
cool down Friday as a weak trough breaks down the ridge and
deepens the marine layer. Increased overnight/morning cloudiness,
especially along the coast, will accompany the trough as onshore
flow and associated moisture increases. Overall no impactful
weather to mention throughout the forecast period. Even though the
next 7 days remain dry, we keep a good tap of onshore flow and
exceptional overnight humidity recovery for any inland location
that do dry out during the afternoons.

.AVIATION...
(00Z TAFS)
Issued at 426 PM PDT Tue Apr 16 2024

VFR with moderate to breezy onshore winds. Winds will become light
with a variation of onshore/offshore direction tonight through
Wednesday morning. Models show agreement that North Bay terminals
may see a reduction of visibility and lower ceilings early Wednesday
morning, with lower confidence that Monterey Bay will reach as low
as North Bay with IFR/LIFR conditions. VFR is expected to return
near 17-18Z as diurnal heating takes into effect.

Vicinity of SFO...VFR through the TAF period. W/NW breezy winds will
diminish to light tonight before rebuilding to breezy by Wednesday
afternoon.

Monterey Bay Terminals...VFR through the early morning of Wednesday
with onshore winds diminishing overnight. Models suggest lower
ceilings and visibility but low confidence that it will become lower
than MVFR/IFR.

&&

.MARINE...
(Tonight through next Sunday)
Issued at 426 PM PDT Tue Apr 16 2024

Ridging continues to dominate, bringing fair weather through much
of the week. Strong and gusty northwest winds are expected
through much of the week, with gale-force gusts expected over the
far northern waters this afternoon through late tonight. Moderate
period northwest swell continues to move through the waters this
week, though shortens in period to around 8-10 seconds near
Wednesday. Light, longer period (18 seconds) southerly swell will
also be present through the week.
