NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
322 am 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 Monday night...radar and surface 
observations have detected light rain showers along the northern 
Oregon coast early this morning...as an upper level shortwave 
trough...currently around 50 miles offshore...approaches. At the 
surface...a weak front is approaching the Washington and Oregon coast 
and will move across the Portland forecast area this 
afternoon...spreading light rain with it. Satellite derived tropical 
precipitable water shows tpw greater than an inch. This moisture 
combined with a 122kt upper level jet nosing into SW 
Oregon...provides a great chance for measurable rain across northwest Oregon 
and SW Washington today...and have increased probability of precipitation. 


Rain showers along the coast will shift inland through the day and 
hang up over the Cascades in the evening. Lingering moisture and calm 
winds will likely result in fog developing overnight tonight into 
Saturday morning. Think the best chance for fog will be along the 
coast...but can not rule out the possibility for fog in parts of the 
northern and central Willamette Valley. 


Another weak front will move across the area Sunday. The chance for 
rain is weaker with this system as the upper jet shifts 
northward...and reduced atmospheric lift. The precipitation on 
Sunday will be very light...possibly more drizzle than rain and be 
restricted to areas north of Salem. 


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. Tj 


Long term...a flat upper level ridge will develop over the Pacific 
northwest Tuesday...before a deeper trough over western Canada slides 
southward along the coast....putting another upper trough over the 
region Tuesday night. Shortwaves moving around the trough will keep 
general troughiness over the area through next weekend. Temperatures 
will generally be near seasonal normals. 


&& 


Aviation...a few light showers are moving inland from the coast 
at 09z. Light showers are expected through the day...then decrease 
this evening. At the coast...much of the LIFR conditions have 
ended as the showers arrived with a mix of low MVFR to VFR. It is 
likely this trend of MVFR to VFR will continue through the 
day...then trend toward more MVFR this evening into Sunday. 
Inland areas...mainly VFR today with occasional MVFR ceilings around 
1500-2500 feet mainly around the lower Columbia River to near kpdx 
this morning. 


Kpdx and approaches...VFR conditions with ceilings in the 5000-7000 feet 
range along with some light showers especially in the afternoon 
hours. 1300 feet ceilings reached kls at 09z Sat and the weak onshore 
flow may be enough to push it into the pdx area so will add a 
period with ceilings of 1500-2000 feet 12z-17z. 


&& 


Marine...another weak front will move across the waters today and 
a third...potentially stronger front Sunday afternoon and night. 
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.
