Severe Weather Alert Descriptions

 Special Statement  Statement as of 3:22 PM PST on November 28, 2014


... Sharply colder weather begins tonight with mixed rain and snow
possible to the lowest elevations through Saturday...

... Freezing rain possible in some valleys Monday morning...

A strong cold front is beginning to move across southwest
Washington and northwest Oregon this afternoon... bringing a sharp
drop in temperature along with it. Snow levels are starting out
well above the Cascade passes... but they will lower dramatically
behind the front.

Based on the latest observations and webcam imagery... it appears
the coldest air is lagging a few hours behind the front. This
should reduce the threat of heavy snow in the Cascades and
foothills tonight. However... mountain roads will be wet from the
rain today and may ice over as temperatures drop below freezing
tonight.

Mixed rain and snow showers are likely Saturday all the way down
to the valley floor. However... any accumulation should be
confined to the hills above 500 to 1000 ft... and would likely be
limited to a slushy inch or so. Drier air should bring a quick
end to any lingering snow showers Saturday evening.

Strong east winds will develop Saturday night and Sunday through
the Columbia River gorge... with gusts of 50 to 70 mph at times.
East winds will spread across the Portland and Vancouver Metro
area as well... with gusts 40 to 50 mph possible late Saturday
night through Sunday.

The cold and dry air ushered in by this wind may bring some
potential for freezing rain Monday morning... but confidence is low
and details are highly uncertain at this point. Continue to
monitor the latest forecasts through the weekend... as details
will become more refined as we get closer to the event.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
240 PM PST Friday Nov 28 2014 


Synopsis...a well-defined cold front will move southeast across the 
forecast this afternoon and evening...followed by a sharp drop in 
temperature overnight. Well below normal temperatures will persist 
through the weekend...with snow levels hovering just above the coast 
and valley floors. Mixed rain and snow showers will persist into 
Saturday as an upper level trough passes through...with perhaps a 
slushy inch or two of snow accumulation in the higher hills. Wet 
snowflakes may mix in from time to time down to the valley floors. 
High pressure will settle in east of the Cascades Saturday night and 
Sunday...bringing strong and chilly east winds through The Gorge and 
across the Portland metropolitan area. A system coming up from the south is 
likely to spread moisture over the cold air Monday...possibly 
resulting in some freezing rain north of Salem during the morning... 
especially in and near The Gorge. 


&& 


Short term...tonight through Monday...a potent frontal system 
extends from about Kelso to Tillamook at the moment...pressing 
southeastward at about 20-25 miles per hour. The front should be through 
Portland around 4-5 PM and Eugene around 10-11 PM. Gusty south winds 
continue ahead of the front...with winds generally gusting 30-40 miles per hour 
both in the Willamette Valley and along the coast. Behind the front 
an abrupt shift to gusty northwest winds occurs...along with a quick 
5-10 degree f temperature drop. By West Coast standards...this is a 
fairly well-defined cold front. 


Despite the sharp drop in temperature associated with the front...a 
look at wsdot webcams shows snow is only falling to about 3000 feet 
at Stevens Pass roughly 3 hours after the cold front moved through. 
We initially had some concern that snow levels would drop quickly 
enough to provide advisory accumulations for our Cascades and 
foothill zones...but based on what is happening to our north it 
appears Post-frontal snow accumulations should be limited to a couple 
inches or so. Temperatures have only fallen into the lower 40s behind 
the front in The Lowlands around Seattle...so it appears unlikely 
that our valleys will see snow from the initial shot of precipitation 
associated with the front. 


Cold advection will continue tonight...but showers are expected to 
decrease in the subsidence behind the front. However the main upper 
trough will swing through the Pacific northwest Saturday...causing a resurgence 
in shower activity. With temperatures mainly in the 30s wet snowflakes will 
be possible down to the valley floors...however sticking snow should 
be relegated to the hills. The West Hills of Portland and the 
Cascade/Coast Range foothills surrounding the Willamette Valley could 
see an inch or two of accumulation...but it should mainly be on 
grassy surfaces due to our recent warm spell. Above 1000-1500 feet is 
where snow may start to stick on the roads and present travel 
issues...though there may be some sun breaks between the showers to 
mitigate this Saturday afternoon. 


Cold high pressure will settle in Sat night/Sunday for drier weather. 
As high pressure strengthens east of the Cascades... easterly 
pressure gradients will ramp up through the Columbia Gorge. Strong 
and chilly east winds will result...and the cold pool again appears 
deep enough for the east winds to affect the whole Portland/Vancouver 
metropolitan area. With the 12z 4km uw wrfgfs kttd-kdls pressure gradients 
approaching -9 to -10 mb and koth-kgeg pressure gradients approaching 
-17 to -19 mb...this east wind event is not expected to be quite as 
strong as our big east wind event earlier this month but it will 
still be formidable. Expect east wind gusts 60-70 miles per hour in the west end 
of the Columbia Gorge and gusts 40-50 miles per hour in the greater 
Portland/Vancouver metropolitan area. This would warrant a Wind 
Advisory...which may be issued by subsequent shifts if models 
continue to project offshore gradients of this magnitude. 


The strong east winds will dry out our air mass Sunday...allowing 
temperatures to fall below freezing most areas Sunday night. Models are more 
or less in consensus now that some precipitation will spread 
northward across our forecast area Monday morning. With the 
combination of cold air in place and overrunning precipitation... 
there is some concern for freezing rain in our northern valleys. The 
greatest threat is in and near The Gorge where cold air will be most 
stubborn. However there is still a lot of uncertainty as to how this 
event will play out...but for now we increased probability of precipitation...freezing rain 
chances...and potential ice accumulations in the grids Monday. Kept 
ice accumulations fairly minimal at this point due to the 
uncertainty...though if current models are to be believed there could 
be more significant icing than presently forecast. Weagle 


Long term...Monday night through Friday...extended models are in 
decent agreement having the next Pacific frontal system lift a warm 
front into the Pacific northwest late Monday into Tuesday morning. 
12z models suggest the front will stall over the region through 
midday Tuesday...with a good amount of quantitative precipitation forecast dumped over the central 
part of the forecast area. Prevailing east winds will continue 
through the Columbia River gorge...and as the precipitation lifts north- 
northeast over the area...could see some threat for freezing rain 
over the Upper Hood River Valley and The Gorge Monday night. This 
will be short-lived as models drag the parent low further south 
along the California coast late Tuesday. Model solutions diverge 
starting Wednesday...as upper level onshore flow develops. Still low 
confidence concerning the overall track of this Pacific system. It 
could either push onshore into northern California and maintain 
seasonably wet conditions as the 12z European model (ecmwf) suggests...or the low 
could push inland over central California with much of the precipitation 
staying south of our area as the 12z GFS suggests. Went more towards 
climatology for the end of the week. /27 


&& 


Aviation...widespread MVFR ceilings with few pockets of IFR this 
afternoon. At 2 PM...cold front extended from just north of ktmk to 
kkls to Montana Rainier. This front will push S across northwest Oregon this 
evening. Once front pushes S...areas behind the front will slowly 
improve to MVFR and low VFR that will persist into Sat am. Expect 
higher terrain to be obscured in precipitation and cloud through Sat am. 
Cold air spreading into region later tonight...with mix of snow 
and rain down to valley floors early Sat. Skies will gradually 
clear from north to S Sat afternoon and drier air arrives. 


Kpdx and approaches...breezy and rainy with MVFR into early this 
evening. Front will move across Ops area between 00z and 02z. 
Winds will turn west or northwest...with rain decreasing after 04z. Will 
see low VFR with occasional MVFR and showers into Sat am. Will see 
snow in showers after 12z...but no accumulations expected as 
ground remains too warm. Drying and VFR after 20z Sat. Rockey. 


&& 


Marine...breezy S winds on the coastal waters...with gusts 25 to 
30 knots. Strongest winds will be close to shore through early this 
afternoon. At 2 am Friday...the strong cold front was just north 
Tillamook...and will continue pushing southward through this 
evening. Winds will turn northwest behind the front...and remain gusty 
through Sat am. 


Seas running 11 to 14 feet into early this evening...but will slowly 
subside tonight and Sat. However...likely to hold close to 10 feet 
on the waters through Sat afternoon. 


Winds ease later Sat and Sat night...with gradients becoming 
offshore and strengthening as high pressure builds over Pacific northwest. Likely 
see gusts 20 to 30 knots in the coastal gaps on sun and Sun night. 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds on all waters through Sat am. 
Small Craft Advisory for hazardous seas on all waters through 
Sat afternoon. 
Small Craft Advisory for rough Columbia River bar tonight 
through Sat am.
