NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
954 am PDT Friday Aug 29 2014 


Synopsis...cooler westerly flow aloft is increasing. This will bring 
clouds and cooler air to the region...along with a threat of showers 
for this weekend. Best chances of showers will be on Saturday and 
late Sunday. Dry and mild weather resumes next week. 
&& 


Short term...through Sunday...surface front currently offshore 
should stall near the coast this afternoon...but the upper 
portion of the front shears off and moves inland in the afternoon so 
precipitation chances will mainly be limited to north Oregon coast and SW 
Washington coast. Radar currently shows some drizzle or light showers 
moving toward mostly the SW Washington coast. 15z hrrr indicates a 
band of light precipitation moving onto the coast and affecting as far south 
as Tillamook County between 19z and 23z which looks to be the best 
chance of rain anywhere in the forecast area today. Any precipitation later 
in the afternoon and evening would likely be orographically enhanced 
so slight chance remains particularly on the windward side of the 
Coast Range and Cascades...with moisture favoring north Oregon and 
South Washington. Cooler temperatures today with more cloud cover and 
lowering 500 mb heights as the upper trough moves into the region. A 
shortwave trough arrives Sat afternoon for a little more cooling and 
a chance of showers...again mainly for the coast and northern 
interior zones. Some upper level support for some showers Sunday 
across the northern part of the forecast area with continued cooler 
temperatures. Bowen/26 


Long term...models are trending toward another system arriving Sun 
night and Monday.Surface features weaken as the front approaches the 
coast...but 850mb and 700mb onshore winds will advect moisture into 
the area. This combined with total precipitable water around 1.25 
inch will introduce chance probability of precipitation to the far northern zones. Further 
on in the week...the upper ridge is not building quite so strongly as 
before. There is more energy being put into carving out a trough over 
western Canada the eventually sags into the western U.S late in the 
week. The air mass will be generally dry so threat of showers remain 
low at this point. High temperatures likely at or below seasonal 
normals. The timing and location of these showers are 
still uncertain as both the GFS and European model (ecmwf) have slightly different 
forecast. These will be further refined with future updates. /64/26 
&& 


Aviation...a weak front will move across southwest Washington and 
northwest Oregon today. The front was seen on radar near khqm at 930 
am with some convective showers over the waters behind the front. 
Clouds have developed over much of western Washington this morning 
with IFR and LIFR along the north coast and mostly MVFR conditions 
inland. Expect the LIFR and IFR conditions to improve along the north 
Oregon coast as the front approaches and lifts the marine 
inversion after 18z becoming MVFR. There will be some drizzle and 
light rain as the front moves in midday along the coast. 
Inland...expect mostly MVFR conditions to continue with a slight 
chance of some light showers mainly from north of kauo 19z-22z. 
Clouds should break out some and lift after 20-21z. Marine layer 
should continue to deepen overnight tonight. Schneider 


Kpdx and approaches...MVFR ceilings 015 to 020 will continue through 
20z then lift some and become VFR after 21-22z. Schneider 


&& 


Marine...weak front moving across the waters today with some 
brief light rain over the waters north of Cascade Head today. 
Winds will remain light southwesterly today and then shift more 
westerly this evening. Several more weak fronts will pass over the 
waters during the weekend. The seas will comprise of a small SW 
swell at around 15 seconds and a northwest fresh swell from the 
Gulf of Alaska around 9 seconds. Light wind waves the next couple 
of days. A northwest swell will build Saturday night and peak around 7 
feet on Sunday. High pressure will rebuild Monday night and 
Tuesday and persistent northerly winds will return to the waters. 
Schneider

Pqr watches/warnings/advisories...
