Area Forecast Discussion
National Weather Service Eureka CA
506 AM PDT WED MAY 25 2016

.SYNOPSIS...Isolated to scattered showers are expected over the
interior mountains this afternoon, then dry weather will stretch
through early next week.

&&

.SHORT TERM (Today through Saturday)...Low clouds persist over
much of the area this morning. One notable exception is over part
of the N offshore waters where downsloping effects from SW OR
terrain has cleared a rather large patch. Clouds should thin over
land today, although weak instability and forcing along with
residual moisture will lead to more clouds and isolated to
scattered showers over the interior mountains. Models are
indicating that a patch of low clouds will remain around the
Humboldt Bay area, and the oncoming shift may need to lean a
little more pessimistic with clouds in that area for the update.

The upper trough will continue to be slowly fill as it shifts
farther SE away from the area today. This will allow a decrease
in instability and moisture as an upper ridge edges closer to the
Pacific coast. There will be a chance for showers from the Trinity
horn to the Yolla Bollys during this afternoon and evening, but
the chance for thunder is expected to be minimal as instability
parameters become less conducive and atmospheric forcing wanes.

Continued drying is expected into Thursday with skies becoming
partly cloudy to mostly sunny across most of the area and little
chance of additional rain. Patchy valley fog will be possible each
night and early morning. Low clouds may continue near Humboldt
Bay, particularly during the overnight and morning hours.

Near normal temperatures through Thursday will warm to above normal
levels over the interior by Friday and Saturday with near normal
values near the coast. /SEC

.LONG TERM (Saturday night through Wednesday)...Mostly dry and
seasonable to warm weather is expected to persist into the middle
of next week as a high pressure ridge remains over the E Pacific
and generally weak disturbances impact the Pacific NW. /SEC

&&

.AVIATION...Stratus brought MVFR conditions to most coastal
airfields early this morning as well as interior valleys. Daytime
heating will gradually erode much of the clouds out of the valleys
but clouds will linger along the coast and especially around
Humboldt Bay. Expect some broken blue skies to emerge along the
coast late this afternoon and early evening but this will be
shortlived as low ceilings will fill back in tonight. Furthermore,
some cumulus will form across the higher terrain of Trinity and
Mendocino counties this afternoon with an isolated shower or two
possible. /KML

&&

.MARINE...North winds will increase today as building high pressure
offshore pinches the pressure gradient across the coastal waters
today. Winds will increase further on Thursday with gusts around 30
to 35 kt by the afternoon for the outer waters as well as nearshore
around Point Saint George, Cape Mendocino, and Point Arena. Small
craft advisories look on track to begin this afternoon with near
gales later Thursday. I considered adding a gale watch but it is a
little to early to issue right now but an upgrade may need to be
considered with the next forecast package. Steep waves will build in
response to the winds and remain elevated through the weekend. The
next signs of improving conditions will be for early next week as
the ridge offshore weakens significantly which will allow the
pressure gradient to relax. /KML

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...
     Small Craft Advisory from 4 PM this afternoon to 5 PM
     Thursday FOR PZZ450-470.
