NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
300 PM PDT Sat Aug 30 2014 


Synopsis...cooler westerly flow aloft prevails through this 
weekend..with a series of weak surface fronts. This will bring 
plenty of clouds and cooler air to the region...along with periodic 
rain showers. The best chances of showers will be this afternoon and 
evening. Weak ridging tries to build back into the Pacific 
Monday...before a deeper trough moves over the area Tuesday through 
the end of the week. 


&& 


Short term...today through Tuesday night... 


A disconnected line of moderate showers has developed along a weak 
front currently moving across the valley. Current orientation of the 
jet stream puts US in the area of favorable forcing in the left exit 
region which has helped to produce stronger showers this afternoon 
and even a lone lightning strike in northern Marion County around 145 
PM. As expected...rain has mostly cleared out on the coast behind the 
front with the exception of a band of light showers near Newport 
which may be a side effect of colocation with the jet streak. Clouds 
will linger behind the front but there should be enough breaks 
overnight to cool down a couple of degrees more than last night. 


Another weak front will move across the area Sunday. The chance for 
rain is weaker with this system as the upper jet shifts 
northward...reducing atmospheric lift. The precipitation on 
Sunday will be very light and be restricted to the northernmost part 
of the forecast area with models continuing to trend downward with 
probability of precipitation. An upper ridge will build Monday...but the models have been 
backing off on the strength of the ridge and expect another weak 
front to clip the northern areas Monday afternoon and evening. 
Ridging tries to establish itself on Tuesday but an upper level 
trough starts to dig into southeast British Columbia. Although weak...an 
argument could be made for some enhanced forcing due to a weak jet 
streak moving into northwest Washington so overall decreased probability of precipitation Tuesday 
but kept them mentionable across the SW Washington part of the 
forecast area. Bowen/tj 


Long term...the models continue to hint at a trough moving into the 
Pacific northwest on Tuesday. This trough looks to stick around 
through the end of next week. Still keeping a slight chance of 
showers in the forecast through Thursday for the northern portions 
of the County Warning Area. Temperatures will trend towards seasonal normals. Late 
next week the models continue to try to develop a cutoff 
low...however...differences between the various models and model 
runs have created a lot of uncertainty. Still leaning towards it 
being drier and slightly warmer for next weekend. 


&& 


Aviation...light showers will continue through this 
evening...then gradually decrease from south to north. Mostly a 
mix of MVFR and VFR conditions inland...with IFR conditions 
likely in showers. Moist onshore flow persists overnight...likely 
bringing some 2000-2500 feet ceilings near sunrise early Sunday am along 
the lower Columbia River. Otherwise...most inland sites will 
remain VFR with ceilings around 5000 feet. Coastal sites will remain 
MVFR and IFR through Sunday am. 


Kpdx and approaches...mix of MVFR and VFR conditions with ceilings 
between 2500-3500 feet. Expect lower conditions in showers through 
04-06z Sunday. A few 2000 feet ceilings are expected again from 14-17z 
Sunday. /27 


&& 


Marine...after a weak frontal passage earlier today...the next 
stronger front moves across the coastal waters late Sunday. Models 
show light SW winds through Sunday...before backing to the northwest by 
Monday. The seas will comprise of a small SW swell of 1 to 2 
feet at around 15 seconds and a northwest fresh swell from the 
Gulf of Alaska around 9 to 10 seconds. Light wind waves the next 
couple of days. A northwest swell will build tonight and peak around 6 
feet on Sunday. High pressure will rebuild Monday night and 
Tuesday and persistent northerly winds will return to the waters.

Pqr watches/warnings/advisories...
