NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
255 PM PDT Friday Aug 29 2014 


Synopsis...cooler westerly flow aloft is increasing. This will bring 
clouds and cooler air to the region...along with a threat of showers 
for this weekend. Best chances of showers will be on Saturday and 
late Sunday. Dry and mild weather resumes next week. 


&& 


Short term...radar showing a thin broken band of precipitation stretching 
from Montana Rainier to offshore Cascade Head but there has been little if 
any accumulation associated with it so far. Updated probability of precipitation for the rest 
of the afternoon to north and west of Portland metropolitan and south along 
the coast to south of Tillamook. Tomorrow looks a bit better for rain 
but mostly over the northern part of the forecast area as a shortwave 
trough moves through during the afternoon. One last trough comes 
through Sunday afternoon ... with the highest probability of precipitation north. The 
highest rainfall amounts should be Sunday evening but even that 
should be less than a tenth of an inch. All in all...none of the 
rainfall will be terribly significant. 


As for models...they seem to be in decent agreement about the overall 
pattern through the weekend. With that being said...there are some 
interesting differences in the likeliness of said pattern to produce 
precipitation on Sunday. The ecm is very generous with probability of precipitation across inland 
areas particularly earlier in the day with the NAM and GFS favoring 
just northern areas and later in the evening and overnight hours. 
Ended up with a solution closer to the GFS and NAM with best rain 
chances Sunday night...waning Monday and clearing out completely by 
late Monday afternoon. 


Long term...the models continue to carve out a trough over western 
Canada that eventually moves into the Pacific northwest on Tuesday. 
This trough sticks around for a while before being sheared off to 
the east on Thursday. Still keeping a slight chance of showers over 
the extreme northern portions of the County Warning Area on Tuesday and Wednesday 
despite the dry air mass associated with the system. Temperatures 
will generally be near seasonal normals. Late next week the models 
try to develop a cutoff low. This has added a lot of uncertainty to 
the forecast. As of now...leaning towards it being clearer and drier 
for the end of next week with temperatures slightly above seasonal 
normals. 


&& 


Aviation...mostly VFR conditions of bkn040-070 as a weak front 
moves across the area this afternoon and early evening. There may 
be a little light rain...mostly aloft as the front passes mainly 
north of kpdx. IFR conditions continue along the central Oregon 
coast and expect that to lift to MVFR as the front passes around 
22z. Stratus should reform overnight with widespread MVFR 
conditions until about 21z Saturday when clouds should lift to 
MVFR. Schneider 


Kpdx and approaches...VFR ceilings of 050-070 expected to last until 
about 10z when clouds will reform and become MVFR after around 
10z.Schneider 


&& 


Marine...weak front moving across the central Oregon coastal waters 
this afternoon and evening with minor impacts to winds which are 
relatively light. Another weak front will move across the waters 
Saturday and a third...potentially stronger front Sunday 
afternoon and night. The seas will comprise of a small SW swell of 
1 to 2 feet at around 15 seconds and a northwest fresh swell from 
the Gulf of Alaska around 9 to 10 seconds. Light wind waves the 
next couple of days. A northwest swell will build Saturday night and peak 
around 6 feet on Sunday. High pressure will rebuild Monday night 
and Tuesday and persistent northerly winds will return to the 
waters. Schneider 


&& 


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