NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
240 PM PDT Sat Sep 20 2014 


Synopsis...an upper ridge over the Pacific northwest will shift 
east to Montana through Sunday. Low level offshore flow will switch 
to onshore flow Sunday. A weak front will reach the area by Monday 
night and a stronger front will reach the area Tuesday night and 
Wednesday. A weak upper trough will linger over the region Thursday 
and Friday but may give way to high pressure for next weekend. 


&& 


Short term...thermally induced low pressure extends from SW Oregon 
to the northern Oregon coastal waters this afternoon with an upper 
ridge over the region. Tonight will be a mild clear night. A surge 
of low marine stratus and fog will move north along the coast later 
tonight and Sunday morning as pressure gradients turn onshore and 
the thermal low pressure moves inland. The coast should see a rapid 
increase in low clouds and fog Sunday morning while the interior 
should remain warm and sunny. Clouds will increase ahead of a weak 
system Sunday night and there is a chance of a little rain or 
showers...mainly coast and mountains...as the weak front breaks up 
over the area. 


Long term...Tuesday night and Wednesday is the period of time when 
western Washington is likely to have period of rain as a stronger frontal 
system moves slowly through the region. There might be two surges of 
fairly strong southerly flow aloft...one Tuesday evening...and another 
later Wednesday or Wednesday night and Tuesday-Thursday do not look like a good time to 
be camping or hiking...especially in the Olympics. There will be a 
broad upper trough centered around 140w Tuesday. GFS height falls 
associated with the frontal system stretch and Peter out in the GFS 
which is not nearly as wet as the European model (ecmwf). Both models show the 
heaviest rain coast and Olympics. After a wet period...the main 
upper trough is likely to drop south Thursday and Friday into calif/NV. The 
GFS and Euro solutions diverge late in the week...the Euro keeps a 
weakening upper trough over the west with a chance of showers while 
the GFS is faster with an approaching upper ridge with a better 
Prospect for dry weather by next weekend. 


&& 


Aviation...an upper ridge over the area will shift inland tonight 
giving increasing southwest flow aloft. At the surface...high 
pressure over southeastern British Columbia combined with a 
thermally induced trough of low pressure over the coastal waters 
will give northeast to east flow tonight. The surface high to the NE 
of the area and the thermal trough along the coast will shift 
eastward early Sunday and marine air along the southern Oregon coast 
will surge northward to the Washington coastal zones during the 
early morning hours. The air mass is stable and dry. Low level 
moisture will increase from the south over the coastal zones after 
12z. The inland areas will remain clear through Sunday with shallow 
fog early Sunday confined to the most fog prone river valleys 
12z-16z. Albrecht 


Ksea...skies will be clear through Sunday with good visibility. 
Expect north wind 10-15 knots this afternoon to become NE 6-8 knots this 
evening and easterly after 09z. Wind will shift to SW 4-6 knots about 
15z sun. Albrecht 


&& 


Marine...high pressure over southeastern British Columbia combined with 
a thermally induced trough of low pressure along the coast will give 
northeast to east winds through tonight. Channeled northerly flow 
over the Puget Sound sound and Hood Canal waters are strong enough to 
maintain a Small Craft Advisory there until 8 PM this evening. 


Easterly winds are expected to increase to Small Craft Advisory 
criteria later this evening through Sunday morning at the West 
Entrance to the Strait of Juan Delaware fuca and the adjacent nearshore 
coastal zone from Cape Flattery to James Island. A Small Craft 
Advisory has been issued for those zones starting at 11 PM this 
evening. 


The thermal trough will shift inland Sunday morning and east of the 
Cascades Sunday afternoon as a weak front moves into the offshore 
waters. This will induce a marine push that will rapidly surge 
northward through the coastal waters around 5 am Sunday. Small Craft 
Advisory south winds are expected for a few hours starting at the 
initiation of the surge over the coastal waters and will be 
accompanied by areas of fog and visibilities less than 1 statute 
mile. Small Craft Advisory west winds are likely to develop over 
portions of the Strait of Juan Delaware fuca during the afternoon and 
evening hours. 


A weak front will cross the waters Monday. A stronger frontal system 
will move through the coastal waters Tuesday or early Wednesday. 
Gale or near gale southeast to south winds are possible over the 
coastal waters ahead of this second stronger front and Small Craft 
Advisory conditions are possible over portions of the inland waters. 
Albrecht

Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory Puget Sound sound and Hood Canal through 8 PM 
PDT this evening. 
Small Craft Advisory West Entrance to the Strait of Juan Delaware 
fuca and coastal waters Cape Flattery to James Island out 10 nm 
starting at 11 PM PDT this evening. 
Small Craft Advisory all coastal zones starting 5 am PDT 
Sunday.
