Area forecast discussion 
National Weather Service Portland or 
200 PM PST Wednesday Nov 26 2014 


Synopsis...a weak cold front off the coast Wednesday afternoon will push 
slowly inland tonight and Thursday. The front will stall over western 
Oregon Thursday night and Friday...then another stronger cold front will 
move S through the region Friday night ushering colder weather for the 
weekend. High pressure over the interior northwest will turn the flow offshore 
by sun for dry but cold weather. Sun night and Monday a system coming 
up from the S will attempt to spread some precipitation up over the 
cold air mass left over from the weekend. 
&& 


Short term...a weak cold front was offshore Wednesday afternoon...with 
layered clouds spread out ahead of the front over the Pacific northwest. As 
the upper ridge over the region shifts east tonight and Thursday the flow 
will turn more to the SW...with the front slowly pushing inland. 
Model soundings agree in showing moisture initially in themid and 
high levels...above 700mb. By late tonight though moisture begins to 
spread in in the lower levels. Dynamics with this front however on 
the weak side...so will be slow to increase probability of precipitation overnight inland 
areas...while the coast and Coast Range will benefit from an 
increasing low level south-southwest flow. With clouds limiting radiational 
cooling tonight and much of the area still in the warm sector... 
should be another unseasonably mild night. Thursday the front appears to 
stall over the region as the low offshore digs in a bit more. With 
baroclinic zone stalled and low level flow a little more onshore 
will take probability of precipitation back up to likely to categorical for most of the 
region. Although there is only modest cooling to air mass with the 
front...clouds and expected occasional light rain will limit high 
temperatures to the 50s most low elevation areas. 


Late Thursday night...and especially Friday better moisture arrives as a northern 
stream short wave drops down through British Columbia with a true cold front 
dropping down the coast ahead of it. Moist isentropic lift in the 
lower levels improves ahead of the cold front as well...best 
depicted in model 290k isentropic fields. As such...potential for 
rain picks up considerably by Friday. 


Models in relatively good agreement in depicting the western 
Canadian trough digging down into the Pacific northwest states Friday night 
and Sat. All models at this point showing a vigorous Continental 
type cold front moving S through SW Washington and northwest Oregon Friday night. 
Pattern is reminiscent of a cold front from back on 19 November 2003 
that brought low elevation snow to interior north parts of the forecast 
area. Keys to doing something similar rely on some of the 
precipitation falling over and behind the front as well as strong 
frontogenetic forcing to allow for dynamic cooling. Model soundings 
at this point indicate snow level falling rapidly behind the front 
Friday night suggesting at least a mix of rain and snow possible down 
to fairly low levels. Whether it would be cold enough to mix snow at 
lowest elevations is anybodys guess at this point...but given the 
agreement in models at this point will carry a mention of mixed rain 
and snow possible for the north part of the area Friday night. Sat sees a 
rather cold air mass settling in over the region behind the front... 
with a lingering chance for showers...potentially mixed with snow in 
the north...as the upper trough moves through. 


Long term...Saturday night through Wednesday...most guidance 
suggests the upper trough axis responsible for saturdays mixed 
rain/snow showers will be moving across the Cascades Sat night... 
with any lingering snow showers coming to end overnight. Expect some 
clearing Sat night as cold high pressure builds down from British 
Columbia...with low temperatures likely getting well into the 20s for most 
spots. With high pressure strengthening east of the Cascades... 
expect strong east winds to ramp up through The Gorge Sunday morning 
and persist for much of the period through Wednesday...with breezy 
conditions spilling into the Portland/Vancouver metropolitan. Monday may be 
a brief break from the winds as a system passes by to our north. 


Meanwhile...a disturbance from the Aleutians is expected to cut off 
from the main Pacific jet and settle off the California coast by 
Sunday...where it will likely linger for a couple days. There is a 
chance this system could come close enough to spread some precipitation 
northward into our forecast area Sun night or Monday. The 12z GFS and 
Canadian models are more aggressive with this than the European model (ecmwf). If 
this occurs...there may be some light freezing rain in portions of 
the Willamette Valley with some snow or light freezing rain in The 
Gorge. Cutoff lows such as this one are notoriously difficult to 
forecast...as models struggle with them in the extended forecast 
period. Where this upper low GOES will dictate the weather through 
midweek...but temperatures are expected to slowly moderate Tuesday and 
Wednesday. Weagle 
&& 


Aviation...generally VFR across the area early this afternoon 
except for areas of IFR along the coast from kast to khqm. Expect 
VFR to prevail through at least the evening hours. Ceilings lower 
along the coast after 03z Thursday as a cold front approaches. Look for 
conditions along the coast to fall into MVFR between 04z to 06z 
with precipitation increasing overnight. VFR should hold over the inland 
areas through at least 12z Thursday...then MVFR conditions 
increase...with higher terrain becoming obscured. Considerable 
low-level moisture resides over the area Thursday which will lead to 
widespread MVFR or worse conditions. 


Kpdx and approaches...VFR conditions to prevail through at least 
12z Thursday. Rain develops over western approaches around 10z then spreads 
east thereafter...with localized MVFR developing after 13z. 
Increasing MVFR or worse conditions Thursday morning through the 
afternoon. Weishaar 


&& 


Marine...wind speeds early this afternoon still at 15 to 20 knots 
with gusts up to 25 knots. Expect speeds to ramp up later this 
afternoon ahead of an approaching frontal system. Should see gale 
force wind gusts over much of the waters by late this afternoon... 
but more so this evening and overnight. Although not a classic 
case...some model guidance is suggesting the potential for minor 
coastal jet enhancement within 20 nm. Could see some gusts up to 
40 knots if this occurs. High-end Small Craft Advisory speeds persist 
Thursday morning. Latest model runs show 20-25 knots northwest-north wind developing 
over the north waters Friday evening then spreading further S overnight 
as a strong cold front drops south out of Canada. The wind turns 
offshore Sat with potential gusts 20 to 30 knots near gaps in the 
coastal terrain. Wind speeds relax sun. 


Seas expected to build to 10 feet this evening then remain at or 
above 10 feet through at least Sat morning. Wave heights drop off 
Sat afternoon as offshor flow develops. Weishaar 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 4 PM PST this afternoon for 
coastal waters from Cape Shoalwater Washington to Florence or out 60 nm. 


Gale Warning from 4 PM this afternoon to 4 am PST Thursday for 
coastal waters from Cape Shoalwater Washington to Florence or out 60 nm. 


Small Craft Advisory for rough Columbia River bar from 4 PM this 
afternoon to 4 PM PST Thursday.
