AREA FORECAST DISCUSSION

.SYNOPSIS...An upper trough will bring unseasonably cool
temperatures across the interior through the work week while
coastal areas can see a mix of sun and clouds each afternoon.
.DISCUSSION...Cloud cover will increase along the northwest
California coast this morning after mostly clear skies prevailed
last night. This will be a result of a weak front sliding over the
region. Most of the coast will see stratus slide in while
interior locations may see some upper level clouds associated with
the boundary. Satellite imagery early this morning showed some
cloud development up the Eel River Valley. Light showers will be
possible across the waters this morning as the front moves
overhead with patchy drizzle possible along the coast.
Precipitation, however, will be light and restricted to the coast
and near the OR/CA border.
Coastal cloudiness should persist over the next several days but
with the presence of the upper trough there will be a better
chance for clouds to scatter out more quickly each afternoon.
Coastal temperatures should remain seasonal this week but may feel
muggy at times.
Unseasonably cool inland temperatures will otherwise persist through
the second half of the week as the broad upper trough ushers in a
colder airmass over the Pacific Northwest. Embedded disturbances
in the upper flow could bring additional light rain/drizzle to the
area early Thursday and Friday mornings but it still looks
marginal with lower confidence at this time. Temperatures should
gradually increase again next week as ridging moves in behind the
exiting trough. /KML
.AVIATION...VFR to MVFR conditions and light winds to calm
conditions will occur at KCEC and KACV today. Cloudiness will
increase today as a low pressure trough approaches the area. Lower
conditions which occur at KCEC AND KACV will be due to stratus
reducing ceilings and/or patchy fog reducing visibilities. VFR
conditions and light winds to calm conditions will continue at
.MARINE...Light winds and low seas will continue across the waters
today as the pressure gradient remains weak. The winds and seas
will gradually increase Thursday and Friday primarily across the
outer waters as an offshore high pressure ridge begins to
strengthen. Small craft advisories are likely across the southern
outer waters Friday through this weekend and across the northern
outer waters by Sunday.
NORTHWEST CALIFORNIA COASTAL WATERS...None.
