AREA FORECAST DISCUSSION
National Weather Service Eureka CA
502 AM PDT Mon May 22 2017

.SYNOPSIS...Hot and dry weather will continue through Tuesday then
inland temperatures will gradually fall back to normal values late
in the work week. Coastal areas will remain more seasonal with
morning clouds and afternoon sunshine. There will be a slight chance
for afternoon thunderstorms across the mountainous interior through
the week.

&&

.DISCUSSION...Hot temperatures will return to northwest California
today as the ridge axis slides across the region. Today is still
anticipated to be the hottest day this week with temperatures across
the interior reaching the 80s and 90s with a few warmer valleys
hitting the upper 90s. Coastal areas won't be as warm as previously
anticipated, but once the patchy morning fog dissipates, you can
expect temperatures in the 60s this afternoon. Tuesday will bring
more hot weather but temperatures will be cooler by a few degrees as
the ridge begins to break down. Coastal clouds are expected again
tonight but expect a very nice day with mostly sunny conditions once
again for Tuesday afternoon. On Tuesday a weak cutoff low will
undercut the ridge and slowly drift towards the western United
States. This will draw modest southeast midlevel flow and increasing
moisture to the interior mountains resulting in a few showers or
thunderstorms for Tuesday and Wednesday afternoons.

Looking into the second half of the week, 500mb heights will fall as
an upper low from the northwest breaks down the ridge of high
pressure. This will allow temperatures to gradually fall to near
normal values for this time of year starting Wednesday through the
end of the work week. Afternoon thunderstorms will continue to be be
a possibility as the cutoff low eventually becomes absorbed into the
upper flow. High pressure will build over the weekend as the upper
trough tracks over the central United States. This will cause inland
temperatures to increase once again over the weekend. kml

&&

.AVIATION...Much of the coastal cloud deck disappeared late on
Sunday. However, recent IR satellite imagery shows the deck re-
forming in earnest early this morning. KCEC and KACV conditions will
continue to vary this morning as the E edge of the cloud deck
impacts these sites. Have forecast improvement later in the morning
and during the afternoon, but expect the cloud deck to continue
offshore thru most of the day. Low level flow will become lighter,
but models continue to hint at eddies/flow reversals along the
immediate coast which could periodically advect more clouds and fog
toward coastal airports. Uncertainty is high with the forecast for
these sites. VFR conditions are expected to continue at KUKI. Winds
will be light. /SEC

&&

.MARINE...N winds will continue to gradually decrease today as the
tighter pressure gradient weakens and pulls offshore. Short period
waves will respond in kind. This will lead to a period of sub-
advisory winds and seas starting around midday today. However,
conditions in the W portion of the N offshore zone will continue to
flirt with low end advisory winds.

N winds are forecast to increase again by late tonight or early
Tuesday. A Gale Watch will likely be needed on one of today's
forecast issuances for the N offshore zone. Wind speeds are expected
to max out late Wednesday with the potential for some storm force
gusts over the N offshore zone. /SEC

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...Small Craft Advisory until noon PDT today for PZZ470-475.
