NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
847 PM PST Wednesday Jan 28 2015 


Synopsis...a weak upper short wave will move over the region late 
tonight into Thursday morning maintaining cloudy skies and possibly 
producing some drizzle. An upper level ridge will build over the 
Pacific northwest Thursday afternoon and Friday and hold through 
Saturday for more dry and mild weather. Easterly winds will develop 
through The Gorge...but with areas of fog and stable conditions below 
temperature inversions in most valley areas. The next chance 
for rain is for late in the weekend. 


&& 


Update...have reduced probability of precipitation for this evening as rain chances look 
minimal. The best chance for any precipitation will be late tonight 
as a weak upper level shortwave trough from the south moves northward 
over northwest Oregon...but still think it will be mainly drizzle. The 
trough should provide enough mixing to prevent widespread dense fog 
Thursday morning. An upper ridge will build Thursday afternoonwith 
increasing east winds. East winds of 25 miles per hour may gust through The 
Gorge and keep fog away from the eastern metropolitan areas Thursday night and 
Friday...but expect valley fog elsewhere. Tj 


Previous short term...tonight through Saturday...the boundary that 
has been over parts of southwest Washington late Tuesday into this 
morning has continued to fall apart and there are not many clouds 
left. The main clouds are the persistent valley low clouds as well as 
some higher clouds associated with an upper short wave along the 
coast. 


The upper short wave along the coast will be over our forecast area 
tonight into early Thursday...then slowly begin to slide southeast 
during the day Thursday and move out of the area Thursday night. Will 
continue to keep a small chance of showers into Thursday morning as 
this feature moves through though confidence of any showers hitting a 
rain gage is not high. Will also keep clouds over the area from it as 
well. 


The clouds will finally collapse and clear Thursday night as the 
upper short wave moves away and an upper ridge starts to move in. 
Expect areas of fog to redevelop Thursday night and continue through 
at least Friday morning especially in the valleys. Will see some 
modest east winds through The Gorge as well Thursday night and 
Friday...that may bring some clearing to at least the North Valley 
areas Friday afternoon. Not much change in the pattern from Friday to 
Saturday...with valley fog continuing and also more modest east wind 
near The Gorge. Tolleson 


Long term...no changes. Previous discussion follows...Saturday night 
through Wednesday...the upper ridge begins to shift inland Saturday 
night as a large low pressure system remains in the central North 
Pacific. Models remain in good agreement that a moist frontal system 
moves into the region Sunday with plenty of showers continuing into 
early Monday. Snow levels lower a bit but still look to remain well 
above the Cascade passes. Another front may arrive around Tuesday. 
Model solutions then diverge a bit for midweek...with the European model (ecmwf) 
continuing a stream of moisture into the 
region while the GFS rebuilds a ridge over the area and pushes the 
moisture north. Given this uncertainty...and the fact that the GFS 
ensemble members maintain a wide range encompassing both of these 
solutions...opted to blend and maintain chance probability of precipitation for Tuesday and 
Wednesday. Cullen 
&& 


Aviation...fog and low stratus is currently redeveloping over 
portions of the Willamette Valley this evening. As the fog 
spreads and thickens expect to see widespread IFR to LIFR ceilings and 
visible through tomorrow morning at most inland taf sites. 
However...easterly winds near the Columbia River gorge should keep 
VFR conditions near kttd. Offshore flow along the coast should 
also keep VFR conditions at the coastal taf sites. Northerly winds 
are expected to develop across the region tomorrow which should 
allow the valley fog and low stratus to clear in the afternoon 
with VFR conditions expected at most sites between 18-21z. 


Kpdx and approaches...VFR conditions are expected through 
tomorrow evening as easterly winds develop near the Columbia River 
gorge. However...there is a slight chance that we may see a brief 
period of MVFR to IFR ceilings and visible late tonight if the winds 
weaken...which should allow fog and low stratus to redevelop. /64 


&& 


Marine...no significant changes were made with the evening update 
as things continue to progress as expected. The low pressure 
circulation is continuing to move northward across our waters 
with high pressure building in behind it. Expect high pressure to 
remain over the Pacific northwest for the next couple of days as a 
thermal low strengthens over northern California. Expect winds to 
remain below 20 knots with seas below 10 feet through at least 
Saturday. /64 


The next frontal system appears to be on tap for Sat night into 
early sun. This system appears to weaken significantly before it 
nears shore...and associated winds are not modeled to reach small 
craft criteria. A second stronger front is being advertised for 
Sun night into Monday. Then a more active pattern appears possible 
for next week...although confidence in the details is low at this 
time. Pyle
