NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
920 am PST Monday Nov 24 2014 


Synopsis...a warm front will spread rain across western Washington 
late this morning through this evening. The warm front will settle 
over western Washington tonight through Wednesday morning...allowing 
rainy and occasionally windy weather...along with mild temperatures 
to continue. Thanksgiving should be wet too...as a weak cold front 
finally moves through. An upper level ridge may bring a brief cooler 
drier period on Saturday. An upper level low may bring a little rain 
on Sunday. 


&& 


Short term...a broad low amplitude ridge is in place offshore this 
morning with the axis along roughly 130w. Models and infrared imagery show 
healthy warm advection moving through the ridge which will spread 
rain inland over West Washington today. Coastal radar shows precipitation forming 
ahead of the warm front just offshore this morning. The offshore 
ridge will build gradually in place today through Wednesday...but 
strong warm advection with strong low level westerly flow aloft will 
continue over West Washington through Wednesday morning. This pattern is a 
classic river flooding pattern with lots of rain over the Cascades 
and high snow levels. 


The initial warm front this afternoon and evening should give a 
fairly uniform dousing to the Cascades. Late tonight and Tuesday 
morning the heaviest rainfall will be focused over the southern 
Cascades south of Snoqualmie Pass. From late Tuesday morning through 
Wednesday morning the area of heaviest rain will shift northward as 
the offshore upper level ridge builds. Snow levels will be 
high...with rain at all the passes. There is still high uncertainty 
regarding how much rain will fall...with the uw and National Weather Service WRF models 
heaviest and the NAM models a step behind. 


The West Washington lowlands should get somewhere between a third of an inch up 
to an inch of rain through Wednesday morning. Lowest amounts should 
be on the east side of the Olympics where westerly flow aloft will 
put the rain shadow. 


A weak cold front will move across the area Wednesday night. Per the 
12z GFS...strong west flow aloft with and behind the cold front will 
give another 24-36 hour shot of moderate to heavy rain to the north 
Cascades Wednesday night through Thursday night. Kam 


Long term...previous discussion from the 3 am afd...the trailing 
cold front should move through western Washington Thanksgiving and 
Thursday night...with precipitation tapering off in its wake on 
Friday. Precipitation with that feature will be fairly decent too. 
It looks increasingly likely that an upper trough will swing into 
the area from the northwest Friday night or Saturday...followed by 
drier colder northerly flow aloft and low level northeast flow 
courtesy of a surface high in southern British Columbia. Mcdonnal 


&& 


Hydrology...latest model guidance points to an initial surge of 
moisture this evening that should be somewhat evenly distributed north-S 
across the Cascades. Then heavier precipitation becomes focused on the 
Cascades S of Snoqualmie Pass late tonight through midday Tuesday. 
Then the baroclinic zone shifts slowly north midday Tuesday through 
midday Wednesday...with the heavier rain over the Cascades from 
Snoqualmie Pass northward. The uw and National Weather Service WRF models show much 
heavier precipitation over the area with 6-9 inches possible through 18z 
midday Wednesday. The hires NAM core has more like 5-8 inches and 
the 12z nam12 more like 2-5 inches. Still lots of uncertainty 
regarding quantitative precipitation forecast amounts and distribution but it looks like a Flood 
Watch will be need to be issued this morning...once the rest of the 
12z models arrive and the morning nwrfc forecasts. Kam 


Previous discussion from the 3 am afd...as mentioned above 3 to 6 
inches of precipitation is likely along the west slopes of the 
Cascades during the 48 hours from midday today through midday 
Wednesday. The snow level will rise to around 6500 feet tonight as the 
strong warm front moves through...and remain in the 6500 to 7500 feet 
range through Wednesday night. 


This pattern of strong moist westerly flow just downstream of a flat 
upper ridge is one of the classic flood-producing patterns for 
western Washington...especially for the rivers flowing off the west 
slopes of the Cascades. This episode looks similar to -- but much 
less severe than -- the pattern that produced the floods of late 
November 1990 and late November 1995. 


The precipitation amounts expected are heavy but not extreme...which 
means that the flood threat will probably be limited to the most 
flood-prone rivers that flow off the Cascades. That generally 
includes the Cowlitz...Puyallup near Orting...Snoqualmie...tolt... 
Skykomish...Snohomish...stillaguamish...and Nooksack rivers. The 
rivers of the Olympics are not likely to flood in this scenario... 
but it does not seem smart to rule out the possibility on the 
uniquely flood-prone Skokomish River. 


If flooding occurs...it would probably be minor. However...the 
flooding could become worse if the focus of precipitation remains 
fixed over a particular part of the Cascades for most of the event. 
There is too much inconsistency in the model solutions to know those 
details at this time. 


We have decided to update the hydrologic outlook for now...rather 
than going to a Flood Watch. The day shift should be in a better 
position to pin down a Flood Watch later today...after the 12z suite 
of model quantitative precipitation forecast is in and the northwest river forecast center has run 
the hydrologic model. Mcdonnal 


&& 


Aviation...moderate northwesterly flow aloft. At the surface a warm 
front will move south to north into the area late this afternoon 
then become stationary over central portions of Washington tonight. 
The low level air mass is stable and will have increasing moisture 
all levels this afternoon through tonight. 


Conditions are mainly VFR this morning with ceilings well above 5k 
feet. Clouds will thicken and lower giving 3-5k feet ceilings this 
afternoon then to MVFR 1-2k feet this evening as rain develops. 


Ksea...discussion above applies. Southeast wind 5-8 knots will become 
southerly and increase to s10g20 knots this afternoon...and to 15g25 knots 
this evening. Chb 


&& 


Marine...southerly winds of 15-30 knots are likely over all waters 
today through Tuesday as a warm front moves north across the waters. 
The warm front will reach the central portions of the waters this 
evening then will become stationary tonight into midday Tuesday. The 
warm front is then expected to move north into southern British 
Columbia Tuesday afternoon and evening. Small craft advisories are 
in effect over all waters including the central Strait where a brief 
westerly push is likely this evening behind the warm front. 


The front is forecast to move back southward through the waters on 
Friday as a cold high pressure system moves into the interior of British 
Columbia. By later Friday into the weekend strong northeast flow is 
possible over the area with Fraser outflow over the northern inland 
waters. 


Hazardous swell of 10 feet or so will continue along the coast 
through this morning and will slowly subside this afternoon and 
tonight. Chb 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory all waters. 
Small Craft Advisory for rough Grays Harbor bar.
