Severe Weather Alert Descriptions

 Areal Flood Watch  Statement as of 4:05 PM PST on November 27, 2014


... Flood Watch remains in effect through Friday afternoon...

The Flood Watch continues for

* portions of western Washington... including the following
counties... Skagit... Whatcom... King... Lewis... Mason... Pierce...
Snohomish... Thurston... .

* through Friday afternoon

* heavy rain is expected to redevelop tonight as a cold front over
British Columbia moves south across western Washington. Strong
southwest flow aloft ahead of and with the front will produce
heavy orographic rainfall over the Olympics and Cascades. An
additional 2 to 3 inches of rain may fall over the north
Cascades from the Snohomish basin northward in the next 24 hours
ending Friday afternoon. The Cascades south of the Snohomish
basin as well as the Olympics may receive an additional 1 to 2
inches. The snow level will be around 6000 feet to 6500 feet
tonight... lowering to around 2500 feet over the far north
Cascades Friday afternoon.

Precautionary/preparedness actions...

A Flood Watch means that flooding is possible but not occurring.
Monitor the weather and be ready to act quickly if flooding is
observed or flood warnings are issued.





 Special Statement  Statement as of 3:28 PM PST on November 27, 2014


... Warm and wet weather will give way to much colder conditions
and possible lowland snow late Friday night into Saturday...
... Cold and windy conditions are expected to develop over the
north interior late Friday night into Saturday...

Big changes in the weather will begin to take place on Friday
morning as a strong cold front moves south across the region.
This front will be accompanied by locally heavy rainfall and windy
conditions. Temperatures will start off mild in the early morning
hours... in the lower 50s in most areas... but will fall through the
40s during the afternoon hours and into the 30s Friday evening.

A Puget Sound convergence zone is expected to form Friday evening.
With temperatures cooling into the lower to mid 30s later Friday
night... some of the convergence zone precipitation may fall as
snow. This will affect mainly Snohomish County and north King
County.

Then a modified Arctic front will move south across the interior
lowlands late Friday night into early Saturday... generating a more
widespread light snow. Modified Arctic air will also flow west
through the Strait of Juan de Fuca. Snow levels will fall below
1000 feet Friday night and to near sea level Saturday morning. It
is too early to tell how much snow will fall over the interior
lowlands or along the Strait of Juan de Fuca late Friday night or
Saturday morning. Most areas will likely see light snowfall
amounts... mainly less than an inch... but some weather forecast
models show up to a few inches in the interior from Seattle into
the northern interior... and along the Strait of Juan de Fuca.

Windy conditions will develop late Friday night into Saturday over
the San Juan Islands... and coastal portions of Whatcom and Skagit
County. These areas may see northeast winds flowing out of the
Fraser River valley increase to 20 to 40 mph with gusts to 50 to 55
mph. The windy conditions will be accompanied by temperatures in
the 20s... which would put wind chill values into the teens.

Stay tuned to the latest updates from the National
Weather Service in Seattle.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
910 PM PST Thursday Nov 27 2014 


Synopsis...a cold front will move south across western Washington late 
tonight and Friday morning producing heavy rain over the mountains 
and over parts of the Puget Sound sound region. A convergence zone will 
continue over Puget Sound sound Friday night...then another cold front 
with modified Arctic air will move south through the area late 
Friday night into Saturday morning. Some snow or rain and snow mixed 
is likely to occur with the convergence zone and along this second 
front. Cool northwest flow aloft will bring mainly cool and dry 
weather Sunday through early next week. 


&& 


Short term...variability appears to be the best word to describe 
the short term forecast. Current radar shows rain not quite as 
widespread as initially thought or forecast...with precipitation east of 
the sound confined primarily to the Cascades. As upcoming front 
starts to make its way into the area overnight tonight and into 
tomorrow...should see that hole start to fill in. Current infrared 
satellite imagery gives pause to that thought however. If frontal 
movement adheres to southeast motion as forecast...cloud layers will 
look to be fairly shallow and thus while rain remains a fair 
possibility...might be less than advertised. Throwing another 
however in the mix though is the current trend in said infrared imagery to 
show some building in clouds. Thus...at this time am inclined to 
side with thought that things just got started a bit later than 
prognosticated and leave inherited forecast intact. 


Models remain consistent with the forecast for Friday and into 
Saturday as the front slowly makes its way through western 
Washington by late Friday morning and producing rain for most 
locations for much of the day. Temperatures will fall steadily 
through the day Friday after frontal passage as colder air starts to make its 
way in. Sufficient moisture is expected to linger and coupled with a 
convergence zone still present in current model output...conditions 
still look favorable for rain to transition into mixed precipitation 
Friday night and lowland snow for overnight Friday and into Saturday 
morning. A lot of this still depends on timing of factors...and as 
the previous paragraph opened...variability has been the watch word 
for the forecast tonight. That said...still opting to play snow 
event on low end of things for now...with most lowland locations 
that do see flakes seeing less than an inch. Passing upper level 
trough scours moisture out quickly by late Saturday morning. That 
and surface high pressure moving into southern British Columbia will 
set the stage for colder temperatures this weekend. Also of note 
with that surface high will be the development of Fraser outflow 
winds. At this time...high wind watch is in place to cover time 
frame from Friday night into Saturday...mainly focusing on western 
Whatcom...coastal Skagit and San Juans...even though wind speeds may 
only make advisory criteria. Another model run should be enough to 
decide whether or not to upgrade. 


Still looking clear and cold for Sunday with temperatures slowly 
rebounding Monday. Smr 


Long term...from 408 PM discussion...only minor changes were made 
to the long term forecast...Monday through Thursday. The set-up has 
a northern stream ridge offshore over the NE Pacific...with cool northwest 
flow aloft over West Washington. Also in the picture is a southern stream 
closed low west of the California coast. Washington appears to be contested 
territory between the northern and southern streams which means 
model battles to determine which stream will win out. The European model (ecmwf) has 
been more or less consistently keeping the area under the cooler 
drier and sunnier north stream through middle next week. The GFS has been 
wobbling between the European model (ecmwf) solution and a wetter southern stream 
solution. Forecasts continue to follow the European model (ecmwf)...but confidence is 
only moderate given the model conflicts and the overall difficulty 
in resolving a pattern like this. Models do agree that a shortwave 
trough will move southeast across the area on Monday. This looks dry at 
this point but more clouds and possibly some light precipitation may need 
to be added to the forecast if model solutions change. Kam 


&& 


Hydrology...as mentioned in the afternoon discussion...there was a 
distinct lull in rainfall today and amounts that fell were less than 
forecast. Rivers have been steady or have risen slowly in response 
to earlier rain. 


The front in southern British Columbia is starting to shift 
southward into the north part of western Washington...and rain rates 
are increasing a bit in the Olympics and north Cascades. The front 
will move south tonight and Friday through Washington...then make 
its way south of the state Friday evening. Models are similar... 
showing another 2-4 inches of rain in the mountains...and our quantitative precipitation forecast 
reflects this closely. Heavy rain should redevelop this evening and 
spread south overnight. The rainiest period is 12z-18z Friday when 
1-1.5 inches of rain is forecast over the Cascades of Snohomish and 
King counties...with up to an inch over The Lowlands of those 
counties. Rain should taper in the afternoon as the air mass cools 
and dries from the north. 


The US Army corps of engineers has taken control of dam operation on 
the Skagit and Baker rivers. As a result the Skagit River should 
have only minor flooding on both the Concrete and Mount Vernon 
reaches. A Flood Warning has been posted for the Skagit River. 


The Nooksack river is also forecast to reach flood stage at north 
Cedarville and Ferndale. However the lack of heavy rain today will 
delay any flooding until late tonight or Friday. 


Heavy rain will reach the basins of rivers flowing off the Cascades 
of Snohomish and King counties late tonight and continue into the 
day Friday. A sheaf of rivers from the stillaguamish south to the 
Puyallup near Orting...including the Skykomish...Snoqualmie... 
tolt...and Snohomish...could all reach flood stage from this short 
but intense burst of heavy rain. Any flooding on these rivers is 
expected to be minor. 


The southern tier of rivers appear to be at less risk of flooding. 
In the models the front seems a bit spent as it moves into the 
southern counties...Pierce and Lewis...and rainfall may not be as 
heavy as in the northern counties. A Flood Watch remains in effect 
for all counties from Whatcom to Lewis...as well as Mason County. 


Speaking of Mason County...the Skokomish River is above flood stage 
and will likely remain near or above flood stage through Friday 
night. The Flood Warning there remains in effect. Burke/mcdonnal 


&& 


Aviation...moist westerly flow continues to impact western Washington 
tonight with rain across the region. Gusty south winds expected at 
the surface. Rain will increase in coverage and intensity late 
tonight through Friday morning as a cold front shifts south through the 
region. MVFR ceilings are likely. North/NE Fraser River outflow winds will 
develop Friday night affecting kbli. A cool air mass will settle over 
the region Sat morning as an upper level trough tracks overhead. 
This system may bring low level snow to the region in the interior 
and Strait of Juan Delaware fuca. This system will exit Sat afternoon or 
evening for dry weather. 33 


Ksea...light rain continues across the region tonight...then 
increases 12-18z Friday as a cold front shifts south through the area. 
MVFR conditions are likely. This front will also bring a wind shift 
with winds becoming northerly by 18z. Late Friday night into 
Saturday...there is a chance for snow at sea-tac with modified 
Arctic air in the area. At this point we are looking at 
accumulations of an inch or less. 33 


&& 


Marine...strong southerly winds will continue over the waters 
tonight as a cold front over southern b.C. Shifts south into western 
Washington. Small craft advisories are in effect for all waters. This front 
will push south through the area Friday afternoon...with winds 
switching to northerly in the interior. Fraser River outflow winds 
will develop behind this front late Friday night and Sat as strong high 
pressure over interior b.C. Sags south. A gale watch is in effect for 
the northern inland waters and East Entrance of Juan Delaware fuca. 
Offshore flow will prevail early next week with high pressure east of 
the Cascades. 33 


&& 


Sew watches/warnings/advisories... 
Washington...flood watches and warnings in effect for portions of 
western Washington. 


Pz...gale watch northern inland waters and East Entrance Strait of 
Juan Delaware fuca for Friday night and Saturday. 
Small Craft Advisory all waters. 
Small Craft Advisory Grays Harbor bar for rough bar.
