AREA FORECAST DISCUSSION
National Weather Service Eureka CA
439 AM PDT Fri Jun 21 2024

.SYNOPSIS...Dry weather is expected for the foreseeable future.
Interior heat will build this weekend, before decreasing steadily to
normal conditions by the end next week.

&&

.DISCUSSION...The extensive field of stratus along the coast is
continuing is reign this morning breaking only south of the King
Range due to downsloping winds leading to compressional warming.
This marine layer is expected to deteriorate throughout the day
before returning to its overcasting glory by the evening. Certain
areas sheltered from the direct onshore wind will see the most sky
clearing. The atmospheric mechanisms leading to this stratus
formation should remain unwavering through the weekend. The most
common ways this layer degrades is when the coastal inversion lifts
and/or weakens or stronger offshore flow develops. So far there are
no clear signals for either. Thus the reasoning for the continuation
of the stratus and grey skies.

Otherwise, interior temperatures will be hot today and tomorrow with
100F degree heat probable for the warmest interior valleys. Today
will most likely be the hottest for Trinity County while Saturday
will most likely be the hottest day with temperatures topping out
around 98-104F in Lake and interior Mendocino counties. The heat is
forecast to diminish on Sunday, but it will still be hot with highs
in the upper 90's to around 100F, mostly in Trinity county. NBM
remains consistent with temperatures trending down around mid next
week as another trough digs offshore over the NE Pacific and
eventually approaches the west coast. There are signs for stronger
ridging from the SW with 500mb heights pumping up above 588DM early
next week. Thus, the downward trend of temperatures may end turning
into another warm up with high temps around 100F or more for out hot
interior valleys. Ensemble members are showing a stronger signal of
warm temperatures persisting through Thursday before another upper-
level trough enters our area next Friday. Otherwise, interior temps
will most likely remain well above normal next week. DS/DB

&&

.AVIATION...12Z TAF
ACV/CEC...A shortwave trough is passing SE early this morning. The
marine layer deepened quite a but in response, but a shallow, low-
level inversion has formed, allowing for LIFR CIGS. As the trough
moves away, heights will very quickly rebound. Soundings reflect
this with ceiling heights becoming compressed and lowering under the
strengthening low level inversion. LIFR CIGS and  perhaps TEMPO fog
will remain in the TAFs for the 12Z issuance as the pattern
dictates, but the deepened state and shortwave influence is
producing variability up to IFR and even MVFR levels. Statistical
guidance (MOS) has not been handling this setup well given the
season which usually more frequents fog. Subsidence behind the
departing shortwave may offer opportunity for scattering before the
stratus fills back in at a shallower level this evening, with higher
probability of fog into Saturday morning.

UKI....The seasonally anomalous deepened state of the marine layer
nearly allowed for intrusion over the mountain from the west before
some lowering occurred and thwarted the stratus advance...thus VFR
will prevail at this terminal. Northwest winds will likely produce
the occasional gust this afternoon in the 15 kt area. Not expecting
much advance of stratus up the valley from the south tonight, but
MOS guidance does show very light southerly winds at the terminal
tonight.

&&

.MARINE....Northerly winds will be on the increase today. Enhanced
winds around and south of Point St George and Cape Mendocino will
reach 30 kts this afternoon and through tonight. Coverage and
strength will be greatest in the waters around Cape Mendocino where
gusts up to 40 kts are forecast. A Gale Watch is out in the Southern
Outer zone 475. These winds will slowly ease some on Saturday. The
southern zones will still see winds up to 30 kts, but with less
coverage. The northerlies will increase again on Sunday with gale
conditions expanding again in the southern zones. Steep, wind-driven
seas will continue to propagate into the inner waters and warrant
Small Craft Advisories. The extended forecast holds a late season NE
Pacific trough which would briefly nudge the stronger northerly
winds farther south mid next week. /JJW
