AREA FORECAST DISCUSSION
National Weather Service Eureka CA
242 PM PDT Sat Sep 2 2023

.SYNOPSIS...Cool weather and beneficial showers will persist
through Sunday. Otherwise, drier weather and near normal
temperatures are forecast to develop across the region starting
Monday.

&&

.DISCUSSION...An upper low was centered over NWRN CA this
afternoon. Afternoon surface heating beneath the upper low
combined with cool air aloft has aided in generally widespread
shower development over interior ridges and mountains. In
addition, model forecast soundings show that midlevel lapse rates
and CAPE profiles are weak, which may preclude the development of
lightning. Thus, only light beneficial rainfall is expected
across the region through evening, followed by dissipating
activity overnight, and then additional isolated to scattered
terrain based redevelopment Sunday afternoon.

The previously mentioned upper low will depart eastward by Monday.
Additional minor upper impulses are then forecast to move across
the West Coast as quasi-zonal flow develops aloft. However,
multi-model guidance indicates precipitation will not be probable
with those features...which will yield a primarily dry forecast
for much of next week. What will be more probable is moderating
interior valley temperatures, with highs returning to the 80s for
many locations across Trinity, Lake, Mendocino, and eastern
Humboldt County by early to middle portions of next week.

.AVIATION...An upper level low off the central CA coast is
bringing somewhat unstable conditions to the area this afternoon.
There is pretty much no marine layer and the coastal airports have
been VFR through the day. Inland areas are generally VFR as well,
although some showers have started to pop up. Tonight some marine
stratus is expected to return potentially bringing lower CIGS.
The HREF doesn't bring the probability of even MVFR CIGS up above
50 percent before 09Z at KCEC and later at KACV. So had trended
the forecast in that direction. The HREF does keep this CIGS in
through much of the day on Sunday at the coast, although they may
be in the MVFR category. Inland areas should generally see less
clouds around Sunday. The exception might be some valley fog in
the morning for areas that saw notable rain. MKK

&&

.MARINE...Generally light southerly winds persist across the
waters this afternoon. Locally stronger winds have developed just
north of Point Arena and likely just north of Cape Mendocino.
These light southerly winds are expected to continue through
Sunday afternoon. Sunday night into Monday the northerly winds are
expected to return once again. Monday they are mainly expected to
increase to around 10 to 15 kt with locally stronger winds just
south of the cape. These are expected to continue to increase on
Tuesday with around 20 to 25 kt widespread northerly winds. These
stronger winds are expected to be shortlived with lighter winds
expected as soon as Wednesday. Winds to 15 to 20 kt are then
expected for Thursday and Friday.

In addition to the steep wind driven waves, there is mid period
wave around 4 to 6 feet at 9 seconds that is currently dominating
the waters. This is expected to drop to around 3 feet at 8 seconds
by early on Monday.

Finally there are some small longer period waves expected this
week. First, a southerly swell around 2 to 3 feet at 17 seconds is
currently moving through the waters and is expected to persist
and get renewed by another one on Wednesday. Also, one of the
first long period northwest swells is expected to move into the
waters tonight or Sunday. Initially this will be around 19 or 20
seconds, but only around 1 to 2 feet. This is expected to build to
around 4 to 5 feet at 15 to 16 seconds on Sunday. This is
expected to then slowly diminish through the week.
