AREA FORECAST DISCUSSION
National Weather Service Eureka CA
408 AM PDT Mon Apr 24 2017

.SYNOPSIS...Wet and windy conditions are forecast for Northwest
California through the middle of the work week as a series of storm
systems slide over the region. After this period of unsettled
weather, drier and warmer conditions are forecast through the
weekend.


&&

.DISCUSSION...Welcome to the start of a wet work week as a series of
storm systems will impact Northwest California. Most areas will see
rain this morning, however, snow levels are forecast to drop to 4000-
4500 feet. The Mad River observation site is currently reporting 38
degrees and just to the northeast, Friend Mountain is showing 33
degrees. This supports Highway 36 and its higher elevation passes
could see minor snow accumulation of 1 to 3 inches. Otherwise, this
is just another run of the mill event. Following today`s event, look
for wet conditions Tuesday morning and afternoon and then again
Tuesday night through Wednesday morning. After that, high pressure
of the Pacific will begin to amplify and move over the region. This
will lead to warming and drying conditions for the end of the work
week and weekend. /KAR


&&

.AVIATION...Moist onshore flow continues to plague the coastal
terminals early this morning in the form of light rain, low cigs and
4-5 mile vsbys. This is expected to continue through much of the day
although some improvement is expected by the afternoon due to a
little mixing.  More significant improvement may have to wait until
later tonight when a brief dry slot allows some drying but this will
be short lived as the next front arrives with more rain and low
clouds. Interior sites should see mostly VFR conditions but perhaps
with some brief periods of MVFR conditions mainly at night and
during the early morning hours.

&&

.MARINE...A weak front has promoted an increase in southerlies last
night and early this morning. The winds should persist through the
morning hours before beginning to diminish and turn west. Unsettled
weather with periods of gusty winds will continue into
midweek...after which...surface high pressure will develop offshore
over the Pacific. This will yield northerly small craft winds over
most of the coastal waters. Otherwise, a westerly swell in the 10 to
15 second range will persist through much of the upcoming week. Wind
waves will also build in response to passing frontal systems early
in the week, followed by small craft seas associated with the longer
period swell Wednesday and Thursday. Northerlies return in earnest
by Friday for all waters while a short period fresh swell
develops.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...Small Craft Advisory until 11 AM PDT this morning for PZZ450.

     Small Craft Advisory until 11 AM PDT this morning for PZZ470.
