Severe Weather Alert Descriptions

 Special Statement  Statement as of 4:44 am PST on November 27, 2014


... Unseasonably mild weather to give way to much colder
temperatures and possible low elevation snow this weekend...

For the past several days... southwest Washington and northwest
Oregon have been experiencing record setting warmth. However... a
major weather pattern change is on the way. A sharp cold front is
expected to move through the region from the north on Friday and
Friday evening. Snow levels will be high initially... but will
fall sharply behind the cold frontal passage. Post frontal
showers may fall as a mix of rain and snow down to the valley
floor at times Friday night and Saturday. Precipitation is
expected to end by Saturday night. Gusty offshore flow is then
expected to develop Saturday night and Sunday. This offshore flow
will usher in frigid conditions as it pulls in air from an Arctic
air mass on the east side of the Cascades.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
327 am PST Thursday Nov 27 2014 


Synopsis...a weak cold front will push slowly inland today. The 
front will then stall over south-central Oregon tonight and Friday. This 
front will begin to lift northward again early Friday. Another stronger 
cold front will move S through the region late Friday into Sat. This 
front will usher in much colder weather. Snow levels will fall 
rapidly Sat...with a rain/snow mix a possibility for the interior 
lowlands. High pressure over the interior northwest will turn the flow offshore 
by sun for dry and cold weather. Another system coming up from the S 
sometime early next week will attempt to spread some precipitation up 
over the cold air mass left over from the weekend. 
&& 


Short term...today through Saturday... 
breezy southerly winds ahead of an approaching cold front are keeping 
exceptionally mild conditions in place across southwest Oregon and 
northwest Oregon this morning. In fact...the temperatures in the upper 50s to 
low 60s being observed across much of the region at current are very 
close to the record daily high temperatures for the last week of November. 
However...the period of mild weather that we have been experiencing 
over the past few days will be coming to an end very shortly. 


The cold front approaching the coast this morning is not terribly 
impressive. Looking at the latest infrared satellite imagery...it is 
apparent that the upper level front and associated moisture has moved 
out ahead of the surface frontal boundary. The surface front can be 
made out on satellite just offshore around buoy 29. With only shallow 
moisture remaining and little in the way of forcing aloft...the 
associated precipitation that is moving onshore is definitely on the 
patchier side. The rain has become a bit steadier over the past few 
hours along the north coast and Coast Range...but most sites are only 
picking up a few hundredths of an inch of rain per hour. 
Still...expect most locations will see a decent steady rain as the 
front pushes onshore this morning and then moves inland through the 
day. The front will eventually stall over southern and central Oregon 
later this afternoon and this evening. 


The other feature of interest that we are watching this morning is a 
persistent stationary baroclinic zone that is currently draped over 
British Columbia and far northern Washington. An upper level trough 
will drive this boundary southward Friday and Friday night as a sharp cold 
front. At the same time...the stalled front over central Oregon is 
forecast to push northward again Friday morning. Between these two frontal 
boundaries...expect rainfall to steadily increase as the day 
progresses Friday. As the sharp cold front from the north dives through 
the region later Friday and Friday night...a much colder air mass aloft 
will move into the region. 


The parent upper level trough will swing into the region from the 
north on Sat to provide some upper level support for Post frontal 
shower activity...while low level onshore flow should provide 
additional moisture to keep showers going through much of the day. 
Based on model 850mb temperatures and 1000-500 mb thickness values...it 
appears that there is the potential for a rain/snow mix to affect the 
interior lowlands at times on Sat. The temperature and thickness indicators 
are only marginal and there is some uncertainty amongst the models 
just how cold the air mass will be...so confidence is not all that 
high that the interior lowlands will see any significant flakes. At 
any rate...with the mild temperatures we have seen over the past few days it 
is unlikely that Road surfaces will be able to cool fast enough for 
there to be major travel concerns. Pyle 




Long term...Saturday night through Wednesday...most guidance 
suggests the upper trough axis responsible for saturdays showers will 
be moving across the Cascades Sat night... ith any lingering 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 early next week. 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...a mixture of IFR and low MVFR conditions have spread 
onto the coast with the first incoming cold front early this 
morning. Conditions at the coast will then continue in that range 
into Friday as the front moves onshore but stalls and some 
precipitation continues at times. Inland conditions are still VFR 
early this morning but will probably see some MVFR conditions as 
the front moves through today. The front stalls and weakens over 
the inland areas this afternoon and tonight before the next front 
approaches from the north on Friday. Model guidance suggests MVFR 
ceilings or low end VFR ceilings will continue over the area behind the 
front into Friday. 


Kpdx and approaches...VFR conditions early this morning but expect 
periodic MVFR ceilings to develop the remainder of the morning. Do not 
expect much change the remainder of today and tonight as ceilings 
hover between MVFR and low end VFR with some light precipitation 
at times. Pt 
&& 


Marine...winds have picked up as the front moved farther into the 
coastal waters overnight...and Gale Warning looks good. Believe 
winds in the central Oregon waters will extend an hour or two 
past 4 am so have extended the gale there. The first cold front 
moves onshore this morning which will allow the winds to east a 
bit...but there is really not much cold air behind this front. 
Then it looks like Small Craft Advisory winds from the southwest 
for the remainder of today...tonight...into Friday. A secondary 
cold front which has much colder air behind it will move south 
through the coastal waters Friday and early Friday evening for 
continued Small Craft Advisory winds...with wind directions 
switching to the northwest behind this front. The northwest winds 
will ease on Saturday...then offshore gap enhanced east winds will 
develop Saturday night and Sunday...probably of the Small Craft 
Advisory variety. These offshore winds will continue into next 
week. 


Seas are running around 10 feet right now but are expected to run 
in the 10 to 13 feet range today into Friday...then continue to 
hover around 10 feet into Saturday...then fall below 10 feet by 
Sunday. Seas today will be choppy with around 8 second periods 
from the southwest. Periods will lengthen to around 14 seconds 
later today and tonight...then shift and be from the northwest 
with periods and 10 or 11 seconds Friday night into Saturday. Pt
