AREA FORECAST DISCUSSION
National Weather Service Eureka CA
232 PM PDT Mon Aug 31 2020

.SYNOPSIS...Hot and dry weather will continue across inland
northwest California through the week. After some sun early in
the week, marine layer cloudiness will tend to expand along the
coast mid to late week. Otherwise, near-record high temperatures
will be possible Sunday into early next week.

&&

.DISCUSSION...An upper-level shortwave trough currently centered
over the Yellowstone region is forecast to progress southeast
across the inter-mountain west tonight. As that occurs, moderate
offshore winds will likely develop across the ridges of northwest
California, but impacts will be limited to locally elevated fire
weather conditions. Otherwise, a boundary layer eddy positioned
offshore from Mendocino County is forecast to move west as the
previously mentioned offshore wind regime develops. Model guidance
shows a similar eddy moving west from the Humboldt/Del Norte coast
tomorrow. As that occurs, southerly low-level winds will develop
along the coast and allow stratus currently located near the
Mendocino Coast to surge north along the Humboldt/Del Norte coast
during Tuesday afternoon. High temperatures will likely be limited
to the mid 60s for locations such as Eureka due to the afternoon
intrusion of cooler marine air.

Generally benign warm/dry weather is expected across the interior
this week. However, upper heights are forecast to build through
the week, with a ridge becoming centered over the western CONUS
late this week into early next week. An anomalously warm deep-
layer airmass is forecast to develop with the ridge, and will
favor near-record high temperatures Sunday into early next week.
Widespread heat-risk impacts will be possible across the region as
a result.

Garner

&&

.AVIATION...Clear, albeit somewhat hazy, skies will continue
along the Redwood Coast through the TAF period, where as the
Mendocino Coast will remain under the influence of stratus. MVFR
to VFR conditions will continue at both coastal terminals during
the next 24 hours. Winds will be gusty along the Humboldt and Del
Norte coasts this afternoon and early this evening, with winds
mostly diminishing by midnight. In addition, an offshore component
above the surface, around 1,000 feet or so, will yield some low-
level wind shear at both KCEC and KACV for at least portions of
the TAF period. Wildfire smoke remains prevalent across Lake and
Mendocino counties and in the vicinity of the Red Salmon Complex
early this afternoon. Expect anywhere from IFR to MVFR conditions
in these areas, with some localized spots of very poor visibility.
KUKI will continue to be impacted by areas of smoke for the
foreseeable future.

&&

.MARINE...Gales and steep, hazardous seas in the outer waters are
expected to persist through the evening hours and begin to
diminish overnight. Winds and seas are less extreme in the inner
waters, but seas will likely continue to propagate into the
northern inner waters over the next day or so. Though, winds and
seas near Point Saint George and Cape Mendocino will continue to
be hazardous through this evening and weaken tonight. Headlines
are in place for all zones except the southern inner waters, where
conditions are much more benign. The diminishing trend will
continue on Tuesday and conditions will be much more favorable
starting on Wednesday. Otherwise, a longer-period northwest swell
will move through the waters starting on Wednesday.

&&

.FIRE WEATHER...East-northeast winds gusting from 15 to 30 mph
are forecast to occur tonight across many exposed ridges in
northwest California. Humidity recoveries will be poor to moderate
above 1500 feet in portions of interior Del Norte county as well
as portions of southern and eastern Lake county. Thus, elevated to
locally critical fire weather conditions will be probable for
those areas. Otherwise, high temperatures will be in the 90s to
low 100s across interior valleys this week, with near-record high
temperatures possible Sunday into early next week.
