NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
905 PM PST sun Nov 23 2014 


Synopsis...a break in the weather is expected through Monday 
morning. A warm front will reach the area late Monday with rain 
developing. Wet weather is on tap for Tuesday and possibly Wednesday 
with high snow levels in the mountains. Another weather system will 
develop over the area Thursday. 


&& 


Short term...just a narrow convergence zone persists around 
Snoqualmie Pass at this time...with wsdot cameras showing snow at 
the pass right now. The convergence zone should wash out any time 
now as onshore flow ends over the next few hours. With predominantly 
precipitation-free weather for the overnight and morning hours...will be 
safe to let the Winter Storm Warning in the Cascades expire at 10 
PM. 


A flat upper ridge will expand northward into the NE Pacific and Pacific northwest 
on Monday and Tuesday. Strong warm advection lift near the periphery of the 
ridge and westerly flow aloft will push a well-defined warm front 
north-NE through the forecast area later Monday and Tuesday. Moisture and 
increasing lift will cause rain to start developing over western Washington 
around middle-day Monday...with expansion and intensification of the rain 
on Monday night and Tuesday. Snow levels will rise substantially on Monday night 
and Tuesday...so only looking for a few hours of snow in the mountain passes 
at the onset of precipitation before a decided change to all rain on Monday 
night. 


The east-west oriented warm front will turn up stationary somewhere 
around latitude 48 to 50 on Tuesday. Western Washington will then be in the warm 
sector south of the front...with 850 mb temperatures running around +5c to 
+7c. Atmospheric moisture content will be high...and strong westerly 
flow aloft will lead to strong orogrphic lift over the mountains this 
will bring a few inches of rain to the Olympics and Cascades on Tuesday 
and Tuesday night...with the axis of heavier rain lifting north to near 
the Canadian border on Wednesday. Haner 


Long term...from previous discussion...the extended forecast into 
next weekend is close to climatology for now with no attempt to sort out 
the differences in the models of late. The general trend has been to 
make Thanksgiving wet but after that the forecasts diverge. The 
baroclinic zone...the dirty ridge warm front...should redevelop and 
merge with a southern stream shortwave in the confluence of the 
upper level flow over Washington...so Thanksgiving could be another wet day. 
Beyond that it is difficult to say whether western Washington will remain wet 
and mild...or cool off like the 12z European model (ecmwf) solution. 


&& 


Hydrology...a hydrologic outlook was issued for rivers flowing off 
the Cascades from Whatcom south through King County. Heavy rain with 
high snow levels are likely in the mountains Tuesday and Tuesday 
night. Nwrfc forecasts show the rivers to keep an eye on are the 
Nooksack... stillaguamish... and Snoqualmie. Indeed...the strong 
warm advection and westerly flow aloft usually favor these basins in 
terms of heavier rain and river rises. Haner 


&& 


Aviation...moderate northwest flow aloft will become westerly on Monday. At the 
surface...a ridge of high pressure is over the area this evening. It 
will move off to the NE Monday as a warm front to the SW of the area 
approaches...then moves into the area Monday evening. The low level air 
mass is stable and mainly dry this evening. High level moisture Monday 
morning will thicken and lower as the warm front approaches the 
area...and light rain is expected to develop Monday afternoon. 


Expect mainly VFR conditions tonight. Some local IFR in fog can be 
expected in more fog-prone river valleys and in the south interior. 
Ceilings will lower to around 030 most areas Monday afternoon then to 
015-020 Monday afternoon as precipitation forms over the area. Albrecht 


Ksea...expect only some scattered-broken high clouds through Monday morning with 
southeast winds 4-7 knots. Clouds will thicken and lower Monday morning and will 
fall to around 030 middle afternoon. Light rain will lower ceilings to 
around 020 late Monday afternoon. Albrecht 


&& 


Marine...winds will become light overnight as a weak ridge of high 
pressure develops over the area then moves NE. 


A warm front will approach the waters from the S on Monday. This will 
lead to increasing S to southeast winds over the waters Monday and Monday night. 
The front will become stationary over the waters or just to the 
north of the waters on Tuesday and Wednesday. Strong SW flow on the order of 
20 to 30 knots can be expected to the south of this front. The front 
will slip back south on Thursday...then Fraser outflow and strong 
offshore flow is possible next Friday. 


Hazardous swell will continue along the coast through Monday morning 
and then subside a bit on Monday afternoon. Haner/albrecht 


&& 


Sew watches/warnings/advisories... 
Washington...Winter Storm Warning in the Cascades expires at 10 PM. 
Pz...Small Craft Advisory coast and West Entrance to the Strait. 
Small Craft Advisory East Entrance to the Strait...Admiralty 
Inlet and northern inland waters starting 7 am PST Monday. 
Small Craft Advisory for rough Grays Harbor bar conditions.
