Area Forecast Discussion
National Weather Service Eureka CA
301 AM PDT TUE MAY 31 2016

.SYNOPSIS...Above normal temperatures and dry conditions will be in
store for the area this week. There is an elevated potential for
scattered showers and thunderstorms across the interior mountains
starting this upcoming weekend.


.PUBLIC...The main weather story for Northwest California is the
continuation of above normal temperatures and dry conditions for the
forecast period. A strong upper level ridge of high pressure will
persist over Western US through most of the forecast period. Do
expect interior valley locations to see daytime high temperatures
rising into the 90s to near 100 degrees. Along the coast, with the
influence of maritime air, temperatures will be in the 60s. Do
expect nocturnal development of marine stratus along the coast. The
extent of marine stratus, however, will be limited by the
availability of low level moisture.

The upper level ridge will flatten on Wednesday, and that may lead
to development of an isolated shower or two over the interior
mountains, mainly east of the forecast area. Little or no QPF is
associated with these showers. Can`t rule out potential for
thunderstorms. The ridge will then rebuild on THursday, and continue
to persist through Saturday. Models are hinting on a development of
a closed upper low later this weekend, and this weather feature may
lead to increased potential for showers and thunderstorms.
However, it is too early to pinpoint the details.

Forecast confidence is slightly above average. Uncertainty stems
from the development of a weak closed low during the upcoming
weekend. Overall changes to the previous forecast package is
minor. /RCL


.AVIATION...VFR conditions and light winds to calm conditions will continue at KCEC
KACV and KUKI through the early morning. VFR conditions and light winds will prevail
at KCEC, KACV AND KUKI this afternoon and early evening. /MFM


.MARINE...The winds and short period seas will continue to gradually diminish today
as the pressure gradient remains weak across the waters. Light to moderate winds
will prevail across the waters this week. The seas will continue to gradually subside
the next few days. However an inland thermal low pressure area will interact with
an offshore high pressure ridge this weekend increasing the pressure gradient across
the waters and subsequently the winds and seas will increase slightly. Small craft
advisories will continue across the outer waters through this afternoon due to short
period seas. /MFM


     Small Craft Advisory until 3 PM PDT this afternoon FOR PZZ470.

     Small Craft Advisory until 3 PM PDT this afternoon FOR PZZ475.
