NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
304 am PDT Monday Aug 31 2015 


Synopsis...a warm front will bring light rain to areas north of a 
Tillamook to Montana Hood line today. Another front will arrive on Tuesday... 
then a showery air mass for Wednesday through Friday. Drier and warmer weather 
returns next weekend. 
&& 


Short term...today through Wednesday... 
westerly flow aloft will push occasional fronts into the Pacific northwest over 
next several days. But main thrust of precipitation will be across 
British Columbia and western Washington. Next front now approaching 
from the northwest...and is pushing across Vancouver Island. This front will 
push occasional rain into SW Washington and the north Oregon coast later 
this am...with the rain spreading inland this afternoon. Threat of 
rain be hard pressed to move south of a Newport to Salem line...so 
will keep only minor threat of rain...if any...in those areas. This 
front will stall over the region tonight...then lift back into 
Washington state. As such...rain threat will also lift northward. But 
will keep quite a bit of clouds over region tonight. 


The next front will move into the region later Tuesday. Once again... 
will clouds increase Tuesday am...with rain threat increasing over region 
from northwest to southeast during the day. This front will bring better threat of 
rain...but again main area of rain will be on the coast and inland 
areas to north of Salem. Once that front passes late Tuesday 
afternoon...air mass will cool...with showery weather on tap for Tuesday 
night and Wednesday. Snow levels also drop down to near 6000 feet...but only 
expecting minor accumulations. 


Models all agree on cool showery weather continue on Wednesday. Many areas 
will likely remain in the 60s for high temperatures on Wednesday...even 
inland. To early to tell yet...but with cool air mass over the region 
and decent instability...could see a few thunderstorms over the 
region. Will let later shifts look at the potential. Seems first few 
days of September will feel likely early October. /Quinton 


Long term...Wednesday night through Sunday. The upper level trough 
axis will remain near the coast late Wednesday into Thursday and 
tries to slide eastward...though models suggest this will be slow to 
occur as a few shortwaves on the back side of the trough may slow 
the progress as the trough slides a bit south. This will bring 
continued cool...and at times showery...conditions to the region for 
Thursday and Friday...with the base of the trough overhead Friday 
before shifting east of the Cascades. Heights look to rise a bit for 
the weekend for dry and warmer weather...perhaps back to near 
seasonal normals for Sunday. Cullen 
&& 




Aviation...VFR across the board at this time. Cold front has 
somewhat stalled north of the area with a fairly steady middle level 
deck in place around fl008 to fl100. It is lowering a bit over the 
north coast with kast ceilings at 050. None of the guidance appears 
to have a good handle on the current situation with models 
indicating clouds much lower. A warm front will cross the area 
around middle-day and bring light rain to the northern areas. May see 
ceilings lower with that frontal crossing but see mixed messages as 
the GFS keeps MVFR ceilings at the coast and VFR inland while the NAM 
brings IFR at the coast and MVFR inland. Given this is a warm 
front and the nam's tendency to overreact with warm 
processes...will follow the GFS as a first guess. 


Kpdx and approaches...VFR the next 24 hours. Periods of light rain 
possible late this afternoon and early this evening. /Jbonk 
&& 


Marine...a warm front moves across the waters today with a weak 
coastal jet developing. Continue to expect winds gusting around 25 
knots across the northern waters with the peak coastal jet winds 
occurring this morning. 


Seas are remaining somewhat steep as the cold front to the north 
is bringing a moderately long fetch and associated west to 
northwest swell. The cold front will slowly drift south tonight 
and Tuesday. Will see seas hover just shy of the 10 feet hazardous 
seas advisory criteria until perhaps early Wednesday morning. 11 
second period swell will persist through Wednesday as well. 


The parent upper low along the British Columbia coast will shift 
east Wednesday and allow northeast Pacific high pressure to build 
over the region for the latter half of the week and the weekend. A 
thermal trough builds up the California coast but doesn't make 
much progress north until closer to Sunday. Will see northerly 
winds gradually ramp up Thursday through at least Monday producing 
late afternoon and evening Small Craft Advisory gusts for the 
central Oregon waters. /Jbonk 
&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 6 PM today for the 
coastal waters from Cape Shoalwater to Cascade Head. 
Small Craft Advisory for rough Columbia bar conditions 
until 9 am today...and again 5 PM to 10 PM today.
