Area Forecast Discussion
National Weather Service Seattle WA
255 PM PDT FRI MAY 13 2016

.SYNOPSIS...Offshore flow and a building upper level ridge of high
pressure aloft will make for a dry and very warm day for most of the
area today. An upper level trough and developing onshore flow will
result in increasing clouds, a chance of showers, and cooler
conditions Saturday through Sunday. A weak upper level ridge will
provide some drying Monday into Tuesday. A frontal system and upper
level low will bring cooler weather and a chance of showers to the
area Tuesday night through the end of next week.

&&

.SHORT TERM...A few clouds here and there this afternoon...but
generally mostly clear skies. Offshore flow and an upper level ridge
remain in place and as such...current observations show the puget
sound area and interior lowland locations all right around the 80
degree mark...while coastal locations are a bit more mild with temps
in the mid 60s to lower 70s. With more heating to be
expected...things look on track to reach high temps from inherited
forecast.

Current models still show the ridge pushing east during the
overnight with trough pushing in for Saturday. Models have nudged
toward a consensus for the track of the low...mainly through central
OR...thus emphasis for showers will likely be first over southern
portions of the CWA before spreading area-wide Saturday night and
into Sunday...before things start tapering off from west to east
Sunday afternoon. Thankfully...this will bring a downward trend in
temps...ranging 60s to lower 70s tomorrow...then mostly in the 60s
for Sunday.

Did not change much pertaining to the forecast that was inherited.
Did pare back on the timing as to when precip will start...really
holding off on precip for the CWA not starting until tomorrow
morning. Inherited forecast also had the risk for thunderstorms
tonight over extreme southern portion of CWA. Not terribly convinced
it will happen...in fact...pretty much sold that it will
not...however...cannot rule out the prospect of something wandering
into the area from the Portland CWA. The northern extent of that
would be extremely limited.  SMR

.LONG TERM...Midnight shift briefed that there had been a model
change...with solutions now showing a ridge for the Monday and into
Tuesday time frame. 12z data from the 3 major
players...GFS...ECMWF...and Canadian all seem to have gelled on this
solution. This ridge probably will not impact temps for Monday but
will see a bump up in temps for Tuesday...generally in the 60s with
interior lowlands seeing temps right around 70. The next upper level
low will start to move south along the Canadian coast...pushing the
ridge eastward Wednesday and starting to impact the area Thursday.
While chance pops start to enter the area Wednesday...they become
more widespread Thursday and linger into the remainder of next week.
SMR

&&

.AVIATION...An upper ridge over eastern Washington will move east
tonight with an upper low moving over southwest Oregon saturday.
Southerly flow aloft will prevail. At the surface...onshore flow
will develop tonight and increase on Saturday. Mid and high level
moisture will move up from the south tonight with conditions
becoming slightly unstable. Low clouds should develop at the coast
this evening and spread partially inland Saturday morning.

KSEA...Some mid and high clouds tonight. Stratus is not expected
to make it to the terminal Saturday morning but it could get
close. Northerly winds 6-12 knots this evening will ease
tonight...then switch to southerly Saturday morning. Schneider

&&

.MARINE...Onshore flow will develop tonight and increase
Saturday. Small craft advisory west winds are expected to develop
in the central and eastern Strait of Juan De Fuca later tonight...then
rise to gale force late Saturday afternoon or evening.

A typical summer-like onshore flow pattern will prevail Sunday
through Wednesday. Diurnal small craft advisory west winds are
likely in the Strait each afternoon and evening. Schneider

&&

.SEW Watches/Warnings/Advisories...
WA...None.
PZ...Small Craft Advisory from 1 AM to 3 PM PDT Saturday for Central
     U.S. Waters Strait Of Juan De Fuca-East Entrance U.S.
     Waters Strait Of Juan De Fuca.

     Gale Warning from 3 PM Saturday to midnight PDT Saturday night
     for Central U.S. Waters Strait Of Juan De Fuca-East
     Entrance U.S. Waters Strait Of Juan De Fuca.
