NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
933 PM PDT Thursday Apr 17 2014 


Synopsis...a fairly vigorous cold front moved through southwest 
Washington and northwest Oregon this evening and was now east of the 
Cascades. The associated upper trough will move through overnight 
with showers decreasing. Weak higher pressure will build in Friday 
with a dry day most areas...except perhaps a few lingering showers in 
our northern Cascade forecast zones. The next cold front will spread 
onshore Saturday morning and early afternoon...moving east of the 
Cascades by Saturday evening. Weak higher pressure will try to build 
in Saturday night and on eastern Sunday. A wave along the next 
frontal system may brush the far north coast zones later Sunday into 
early Monday...but then the main cold front will stall off the coast 
as a large chunk of energy digs south toward California...finally 
moving onshore late Monday into Tuesday. The pattern will remain 
fairly unsettled next week. 
&& 


Short term...tonight through Saturday...a cold front has moved 
through southwest Washington and northwest Oregon this evening...and 
was now east of the Cascades. There are some shower over the Coast 
Range and the Cascades...but as the low level flow turns more 
northwest and an associated upper trough moves east...these will 
decrease overnight. Clouds are not very solid offshore...and expect 
some cloud breaks overnight especially south of the Columbia 
River...and those will be the best areas for some local fog forming 
later tonight and early Friday. 


Weak higher pressure builds in Friday...but some northwest onshore 
flow remains for awhile mainly north of the Columbia River...and a 
few showers may linger for a while Friday in the South Washington 
Cascades. There is also an upper disturbance moving through the weak 
upper ridge on Friday that may give some middle and high clouds as 
well...and may also affect the lingering South Washington Cascade 
showers. 


Look for clearing Friday night as we are briefly in between 
systems...with some clouds increasing late Friday night ahead of the 
next system. 


The models are looking pretty consistent with the next front for 
Saturday. Timing looks consistent as well. It looks as though the 
rain will develop pretty early Saturday on the coast...and reach the 
inland valleys in the middle to late morning on Saturday. The front 
moves through at a decent pace on Saturday...and appears to be east 
of the Cascades by Saturday evening as the parent upper short wave is 
already moving into central Oregon by 00z Sunday. Have therefore made 
some adjustments to the forecast grids for Saturday to account for 
the confidence in more detailed timing. Tolleson 


Long term...no changes. Previous discussion follows... 
Saturday night through Wednesday...Topsy-turvy weather continues Sat 
night as weak 500 mb ridging tries to form over the Pacific northwest and 
surface high pressure again takes control. A deepening Gulf of Alaska 
trough will help amplify the ridge a bit more sun. SW Washington zones still 
vulnerable to some light precipitation Sunday...but the more south one 
travels the more sunshine there should be and temperatures again warm back 
to the lower 60s. As the flow amplified more Monday...we could have 
another dry morning...with a weak cold front which looks to trigger 
some showers in the afternoon...especially for the Cascades...with a 
better threat inland elsewhere in the evening. 


Looks like much of the extended is characterized by cool and damp 
conditions as a deep upper low Parks itself in the Gulf of 
Alaska...and sends waves of showers through the area. Expect near to 
below normal temperatures through much of the period..with the 
potential for some accumulating snows in the Cascades as snow levels 
will be down near the passes beginning late Monday night into 
Tuesday. /Kmd 
&& 


Aviation...a cold front and associated wind shift to the west/northwest has 
moved through the Willamette Valley this evening and is now pushing 
into the Cascades. Conditions have improved to VFR for many inland 
sites behind the front...while mainly MVFR is being observed at the 
coast. Expect scattered showers along with a mix of VFR and MVFR 
conditions through the rest of the evening...especially at the coast 
and for the northern valley. Partial clearing overnight along with 
weakening winds will likely lead to patchy fog or low stratus 
development between 09z and 12z...with the best chance over the 
central and southern Willamette Valley. Expect conditions to improve 
by 16z to 18z tomorrow and remain VFR as brief high pressure moves into 
the region. 


Kpdx and approaches...expect VFR with a brief period of MVFR possible 
passing showers through about 06z to 09z. Partial clearing overnight 
will likely bring low stratus or fog between 09z and 12z. Expect VFR 
to redevelop between 16z and 18z and remain through the rest of the 
day. Pyle 
&& 


Marine...a cold front pushed onshore during the late afternoon and 
evening. Winds over the waters have now shifted to the northwest and have 
begun to subside behind the front. There are still a few localized 
gusts in the 20 to 25 knots range. Seas are running just about as forecast 
at 8 to 10 feet...with the highest seas over the northern waters. Will 
allow the existing small craft advisories for winds and seas to run 
through the expiration time of 06z. Expect winds and seas will 
gradually drop off overnight as high pressure builds over the waters. 


Then expect a fairly quiet period Friday into early Sat with the high 
pressure in place. Another front will push across the waters midday 
Saturday. Expect more 25 to 30 knots winds with this front. A large 
westerly swell will follow the front late Saturday into Sunday. 
Latest model guidance brings seas between 17 and 20 feet between 
approximately 2 am and 2 PM Sunday...before they begin to slowly 
decrease. Seas look to remain above 10 feet through the first half of 
next week though. Pyle/neuman

Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 11 PM PDT this evening for 
coastal waters from Cape Shoalwater Washington to Florence or out 60 nm. 


Small Craft Advisory for hazardous seas until 11 PM PDT this 
evening for coastal waters from Cape Shoalwater Washington to Cascade 
Head or out 60 nm.
