AREA FORECAST DISCUSSION
National Weather Service Eureka CA
335 PM PDT Fri Jul 8 2022

.SYNOPSIS...Interior heat will build this weekend and peak on
Monday. Dry weather with seasonably hot temperatures will persist
in the interior for the remainder of next week. Stratus and fog
will continue to blanket most coastal areas during the nights and
mornings through next week.

&&

.DISCUSSION...A compressed marine layer has been locked onto the immediate
coast through the day. High resolution model guidance, mainly the
ARW, and BUFKiT profiles indicate the shallow marine layer persisting
through this evening with perhaps some deepening later tonight
and Saturday morning as a decaying 500mb shortwave trough approaches
the coast. Some light coastal drizzle seems possible, however based
on ARW model, measurable drizzle appears unlikely. Some isolated
weak showers will also be possible (10% chance) over the mountains
of northeast Trinity late Saturday afternoon, mostly over the
Alps. The ARW, NSSL and NAM-nest models lend support for isolated
mountain showers, however the HRRR and global spectral models remain
dry.

Interior heat will build this weekend and peak on Monday. Temperatures
probably will not be too hot on Saturday as a 500mb trough transitions
over the area and afternoon westerly breezes develop in response
to central valley heating. Highs on Saturday should be near normal
for early July. Weak upper level troughiness will linger into early
Sunday before upper ridging and large scale subsidence builds full
force. 850mb temperatures increase to 23-26C, however diurnal winds
may cap daytime highs. The warmest day will be on Monday as the
ridge aloft pumps up over the area and 850mb temps soar to 25C+.
Offshore flow in the morning will suppress marine the layer and
confine it right to the coast. Coastal areas may warm into the
lower 70's north of Cape Mendocino, mainly north of Trinidad and
along the Del Norte coast where the offshore flow is forecast to
be robust. Temperatures of 90F or more are highly probable inland
with hotter valleys in Trinity, Lake and Mendocino counties 100F
or more. Even northeast Humboldt around Orleans, Hoopa and Willow
Creek will likely have 100F+ heat. The heat risk will generally be
moderate, however with temperatures peaking around 105-110F in
eastern Trinity county on Monday, a heat advisory may be warranted.

The interior heat will moderate for the remainder of next week,
however it will remain seasonably hot all next week. Marine air
and diurnal westerlies should intrude inland each day. Also,
ensemble and deterministic guidance continues to indicate
southerly winds aloft and some mid level humidity by mid next
week. The ECMWF ensemble has 1 member of 50 with precipitation
from a disturbance emanating from the subtropics around Thu. The
chance for precip or storms remains unlikely (less than 10%).

&&

.AVIATION...The marine layer has clung to the Northern California
Coast into the afternoon. Spiraling marine stratus off of Cape
Blanco, Oregon continues to spin slowly southward past Del Norte
County causing an influx of marine stratus into northern Humboldt
County and Del Norte County. There also seems to be a general push
of marine stratus onshore north of Cape Mendocino and along most of
the Mendocino Coast that is slowing the clearing into this
afternoon. Because of this push of marine stratus onto the region’s
coast, an IFR to LIFR cloud base could remain through most of the
afternoon. There could be potential clearing to MVFR late this
afternoon/early evening, but by late tonight IFR to LIFR ceilings
will infiltrate along the coast and inland down river valleys. Lower
visibilities and fog are also possible along the coast early
tomorrow morning. Interior areas of the region will remain in VFR.
Interior Southern Mendocino County and Lake County will see gusty NW
winds later this afternoon and into tonight, but overnight winds
will be calm and variable.

&&

.MARINE...A stalled low pressure system will continue to fizzle out
into tonight allowing the Pacific High to regain control of the
coastal waters. A small area of advisory level northerly winds will
develop through the afternoon in the lee of Cape Mendocino; however,
winds throughout the coastal waters will ramp up through the night.
Winds will continue to strengthen to advisory level in the outer
coastal waters and the southern inner waters by Saturday evening and
night. From Sunday afternoon through night, near gale to gale
sustained winds and gale gusts will be probable around Point St.
George; however, the coverage isn’t large enough to have a gale
warning for the northern inner waters. Steep seas will develop
throughout the coastal waters Sunday afternoon due to the
strengthening northerly winds and continue into next week. A small
westerly swell continues to diminish and ends by Sunday morning. A
couple of westerly swells are expected to move through the coastal
waters by the middle to end of next week.

.EKA WATCHES/WARNINGS/ADVISORIES...
