NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
834 PM PDT Wednesday Sep 17 2014 


Synopsis...low pressure off the north calif coast will slowly weaken is it 
moves into north calif through Thursday evening. Southerly flow over the 
region will maintain clouds and scattered showers. Drier weather for 
Friday as high pressure builds...with much warmer and drier conditions 
this weekend. Cooler unsettled weather returns next week. 
&& 


Short term...no changes in overall forecasts and trends. Most 
showers this evening continue to be over SW Oregon and along the 
coast. Decent rainfall over SW Washington and Willapa Hills where 
0.25 inch fell at Huckleberry RAWS in hills above Longview...and 
about 0.15 inch near Hoquiam. Not much elsewhere...with only a few 
hundredths along the Oregon coast and trace amounts over the inland 
valleys. Overall...showers will continue to stream northward 
tonight...but again best threat of actual rainfall will remain over 
coastal areas down into SW Oregon. 


Will maintain minor threat for a thunderstorm or two this evening 
over Lane County Cascades as weak anomaly and the left exit region 
of a 90kt jet will brush that area tonight as it moves across 
southern Oregon. 


For Thursday...models continue to hint that low level warm air 
advection just offshore and a subtle low to middle level boundary will 
concentrate shower activity across far northwest Oregon and southwest 
Washington late tonight into Thursday morning. When coupled with 
increasing westerly flow at 850mb...measurable rainfall or more than 
0.01 inch looks likely on the coast...Coast Range and Cascades. 
Wetting rains which are rainfall of at least 0.25 inch still do not 
appear all that promising...but there is certainly a chance 
especially near the coast. 


For Friday...building 500mb heights Thursday night and Friday should 
result in conditions drying out considerably across most of the area. 
The lone exception to this will be across extreme northwest Oregon 
and southwest Washington where a dying front pushing into the region 
from the northwest may bring a shower or two Friday. 


For Saturday...thermal low pressure over northern California will 
build northward up the coast...bringing increasing offshore flow and 
a return to much warmer temperatures. Areas of smoke will once again 
become a concern over the Willamette Valley during this period. 
/Neurockeman 




Long term...Sunday through Wednesday...Sunday warm temperatures 
will continue due to continued easterly flow. Sunday afternoon winds 
will shift to more southwesterly with a marine surge along the coast 
bringing clouds back to the coast. Southwesterly winds and marine- 
sourced air will cool temperatures for Monday and Tuesday ahead of 
our next weather system...an upper-level trough approaching the West 
Coast on Monday. The GFS...ECMWF...and dgex are in good agreement 
that while the longwave trough stalls in the Gulf of Alaska...a 
series of shortwaves sourcing from the parent low off the West Coast 
will bring several chances for rain across our area Tuesday and 
Wednesday. The models recently have tended to generate a lot of 
moisture further in the forecast period...then back off as the event 
approaches. For this reason...I am hesitant to commit to this being 
a productive rainfall event. -McCoy 
&& 


Aviation...middle and upper level clouds continued to stream north over 
western Oregon this evening. Conditions were primarily VFR across 
the region...except for some spotty MVFR conditions in light rain 
and fog along the coast. VFR conditions expected to continue most 
areas through 18z...although some areas of MVFR conditions are 
likely to develop...primarily near the coast after 09z. 


Kpdx and approaches...VFR likely to continue through 18z. 
&& 


Marine...winds expected to remain below small craft criteria 
through Friday morning. A trough of low pressure developing north up the 
coast late Friday and Friday night will strengthen north winds...potentially 
up to small craft criteria Friday night into early Sat. A return 
to quieter conditions is likely to return for the rest of the 
weekend. 


Seas expected to remain in the 5 to 7 feet range for the next few 
days...but there are some indications a westerly swell arriving 
Sat could drive seas up close to 10 feet. 
&& 


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