Area forecast discussion 
National Weather Service Portland or 
248 PM PDT Sat Aug 29 2015 


Synopsis...the strong low that brought high winds to the coast and 
windy conditions inland today has moved north of the area with slowly 
subsiding winds. The next cold front was approaching the South 
Washington and north Oregon coast this afternoon and will move across 
southwest Washington and northwest Oregon tonight with more rain and 
more breezy conditions especially at the coast. There will even be a 
slight chance of thunder this evening mainly near the coast. Onshore 
flow behind the front will keep a fair amount of showers over the 
area on Sunday. A trough will remain near the coast through the 
coming week...keeping things cool and showery at times.

Short term...the strong low that produced high winds along the coast 
and in the Coast Range today and windy conditions inland has now 
moved well north into northwest Washington and southern b.C. Winds 
in our area are tapering off from south to north and have been 
dropping the warnings and advisories as appropriate this afternoon. A 
public information statement was issued earlier this afternoon with 
peak wind values across the area...and they were pretty impressive. 
There are still some showers over the Coast Range in southwest flow 
that will affect the northern zones at time this but less in the 
southern zones. With temperatures in the lower 70s there is a small chance 
of thunder this afternoon as well. 


Attention now turns to the next front...currently approaching the 
South Washington and north Oregon coast. The north part of this front 
is merging with the bent back occlusion of the strong low that moved 
north earlier today. There is a lightning strike along this front 
this afternoon as well...west of Astoria. This front will reach the 
coast this afternoon and early evening and spread through southwest 
Washington and northwest Oregon overnight tonight. As indicated 
above...this front is somewhat convective in nature...and there will 
be a slight chance of thunder with it along the coast and in the 
north interior zones again. There is some wind with it... especially 
near the coast...but not as windy as today. Look for gusts to around 
40 miles per hour at the normally windier exposed locations along the coast this 
evening. 


Onshore flow will continue behind the front on Sunday for decent 
shower coverage through the day...especially over the mountains. 


Monday will continue to see onshore flow with a mixture of clouds and 
sunshine and below normal temperatures. The main threat of showers on 
Monday will be in the north and near the higher terrain. 


On Tuesday the models agree another frontal boundary will drop in 
from the north and increase the chance of rain again. Tolleson 


Long term...Tuesday night through Saturday...an upper trough will 
remain along the Pacific northwest coast through much of the extended 
period. The models show another decent piece of energy swinging 
through around Wednesday or Thursday for a better chance of 
showers...but the timing varies a bit. The models are indicating it 
may dry out and start to warm up some next weekend. Tolleson

Aviation...mix of VFR and MVFR along the coast...mostly VFR inland. 
Gusty southerly winds are starting to weaken across the area. A weak 
front approaching the coast will bring MVFR ceilings to the coast for the 
overnight hours through Sunday morning. Models suggest MVFR ceilings may 
continue into the afternoon hours. Southerly winds will continue to 
gust to 25 knots at coastal taf sites overnight until early Sunday 
morning when winds drop to 10 to 15 knots. Inland...VFR ceilings may drop to 
MVFR with rain as the front moves through this evening... improving 
back to VFR behind the front for the overnight hours through Sunday 
morning. There is a slight chance of a thunderstorm with this front 
mainly in the northern Willamette Valley. Southerly winds may 
increase again just ahead of the front to 20 to 25 knots then will drop 
to around 10 knots for the overnight hours through Sunday morning. 


Kpdx and approaches...VFR conditions this afternoon. S winds 
decreasing this afternoon and evening may briefly increase back up to 
20 to 25 knots just ahead of front moving through this evening. Front 
will bring rain which may lower ceilings to MVFR. Behind the front...ceilings 
should improve back to VFR for the overnight hours and remain VFR 
through Sunday morning. -McCoy

Marine...another weak front is starting to move through the waters 
this afternoon. There is a chance for an isolated thunderstorm as 
this front moves through the waters this afternoon. South-southwest winds around 
20 to 30 knots gusting to 40 knots this afternoon will decrease to 15 to 20 
knots gusting to 25 knots behind the frontal boundary...but will continue 
to be from the south-southwest overnight tonight. Seas currently up at 15 to 18 
feet will lower through the evening to 10 to 12 feet late tonight. Winds 
may continue to gust to 20 to 25 knots through Sunday morning until they 
drop below 20 knots around midday. Seas will drop to around 8 to 9 feet by 
Sunday morning as well. 


Swell being generated from the upper-level trough sitting over the 
Gulf of Alaska will keep seas up around 7 to 9 feet through mid-week. 
Winds remain south-southwest-Erly until Tuesday or Wednesday when another front 
will move through the waters...veering winds back to the 
west-northwest. -McCoy
