NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
215 am PDT Thursday Oct 2 2014 


Synopsis...increasing high pressure will bring above normal 
temperatures to the region through at least early next week. There is 
a chance some light rain may fall across southwest Washington over 
the weekend as a dying front sags southward...but all in all...no 
major storms are anticipated through the middle part of next week. 


&& 


Short term...today through Sunday...aside from some patchy morning 
fog from time to time...relatively benign weather is in store through 
at least early next week as upper level high pressure dominates our 
weather. In fact...temperatures will climb 5 to 10f warmer than 
normal over the weekend. 


In the immediate short term...clouds between 5k and 10k are streaming 
southeastward across the northern half of the forecast area. Models 
suggest these clouds will dissipate through the day. 
Meanwhile...points south of Salem generally remain clear. As a 
result...adjusted the morning fog forecast to favor the southern 
half of the forecast area where radiational cooling is currently 
more efficient. 


With building 500mb heights today...thermal low pressure will build 
up the Oregon coast this afternoon and tonight. This should result in 
some modest northerly winds for the Willamette Valley this afternoon 
and evening. As pressure gradients tighten across the 
Cascades...expect breezy east winds to develop near the west end of 
the Columbia Gorge tonight and Friday...but they will remain more 
nuisance in nature. 


An atmospheric river poised to hit southwest British Columbia over 
the next 36 hours will weaken considerably as it shifts southward 
into western Washington Friday night into Saturday. This should 
result in clouds increasing across our northern zones during this 
time. This may also act to limit morning fog coverage over the 
weekend. As the front shifts closer to the County Warning Area Saturday afternoon 
into Saturday night...a shower or two may impact southwest 
Washington so slight chance probability of precipitation were retained across the far 
north. /Neuman 




Long term...models continue to advertise upper level ridging over 
the region early next week will give way to more zonal flow. This may 
allow a weak shortwave trough or two to impact the region at some 
point towards the middle of next week. As a result...slight chance 
probability of precipitation were kept in the forecast in the extended. Nonetheless...the 
probability of precipitation are still a touch lower than climatology and temperatures were kept 
near to slightly above normal. /Neuman 


&& 


Aviation...high pressure remaining over the region may allow fog and a 
low stratus to develop in the southern part of the inland valleys 
this morning. Across the north part of the Willamette Valley...along the 
north coast and over SW Washington a deck of middle level VFR clouds was spreading 
in that will likely keep conditions VFR this morning. So the 
likelihood of IFR conditions this morning over the interior valleys 
ranges from about 70 percent down near keug to just 20 percent vicinity 
kpdx...most likely between 12z and 20z. Along the coast clouds in 
the north and a light offshore wind along the central Oregon coast will 
will limit the chances of IFR conditions to around 30 percent at 
kast and konp. 


Any low clouds and fog should burn off by 20z today leaving the 
region VFR for the afternoon and evening hours past 06z. 


Kpdx and approaches...conditions are likely to remain VFR this 
morning as a deck of middle level clouds moves across the area. Should 
clouds break up some...there is a 20 percent chance of IFR 
conditions in fog or low stratus developing between 12z and 20z. VFR 
conditions this afternoon and evening will persist past 06z. 


&& 


Marine...overall remaining rather quiet through the weekend. High 
pressure remaining offshore will keep winds roughly out of the north. A 
trough of low pressure along the S Oregon coast will cause winds to pick 
up each afternoon and evening to around 20kt before weakening again 
in the mornings. Seas around 5 feet today and Friday expected to increase 
to around 7 feet for the weekend as swell arrives from the west. 


Strengthening north winds Monday may see winds in the southern waters 
gusting to 25 knots by the end of the day. 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...none.
