Area forecast discussion 
National Weather Service Eureka California
351 am PST Wednesday Jan 28 2015

Synopsis...dry conditions are expected Wednesday into the
weekend as a ridge moves over northern California.


Discussion...a weak trough moving through the Pacific northwest
in conjunction with a cut off low just off of Southern California
continue to bring mainly high clouds to northwest California. An
isolated light rain shower (or maybe some sprinkles) is possible
again today across the interior zones but very little, if any
precipitation is expected. The somewhat dry pattern will continue
into the weekend as a ridge of high pressure moves back over
northern California. By early next week the models are hinting at
the ridge weakening and moving eastward as a trough develops
offshore. This pattern change would bring US cooler temperatures
and a chance of light rain to the region as a weak front sweeps
across the region during the Sunday/Monday time frame. Have kept
probability of precipitation around 30% during this time frame as confidence remains low.
The only other issue Worth mentioning is possibility of moderate
to high risk sneaker waves occuring along the coast Thursday
afternoon as a long period swell interacts with a high tide. (See
marine discussion below).


Aviation...a passing low pressure system will transport high
cloud cover over the region and maintain lighter winds with a weak
pressure gradient. Patchy ground fog could reduce visibilities
slightly late in the taf period however VFR is expected to prevail
across northern California. Kml


Marine...light flow across the coastal waters today will turn
northerly this evening through Thursday as ridging develops behind a
passing low pressure system. Northerly flow will increase on
Thursday as the pressure gradient tightens bringing small craft
winds and steep seas across the outer waters into early Friday
morning. An advisory may be needed for the southern outer waters as
early as this evening followed by the northern outer waters later
tonight. For now, will wait to issue any advisories to better nail
down the timing. As far as the wave environment GOES, fore runners
to a northwesterly swell born from a large Pacific low pressure
system will arrive today and build across the waters through the
weekend. Sneaker waves with the building swell continues to pose a
threat but on Thursday afternoon with the incoming tide. I think
nwps is over doing the shorter period wind driven waves which would
mean a higher risk for sneaker waves. Beach goers should exercise
caution with the building swell Thursday afternoon. Kml


Eka watches/warnings/advisories...
Northwest California coastal waters...none.
