NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
850 PM PDT Monday Sep 1 2014 


Synopsis...a vigorous fast moving frontal system will bring a 
little rain to western Washington on Tuesday. A convergence zone 
will form over Puget Sound sound behind the front late Tuesday afternoon 
and evening. Dry north flow aloft will bring sunny weather by 
Wednesday afternoon. An upper level ridge will build over the region 
Thursday for sunshine and a warming trend that will last into next 
weekend. 


&& 


Short term...partly to mostly cloudy skies over West Washington this evening. 
With no precipitation on radar the dry forecast for tonight looks Good. 


Water vapor imagery showed a vigorous upper level trough over the Alaska 
Panhandle at 03z. Models remain in good agreement in bringing the 
trough southeast along the b.C. Coast tonight...then down over West Washington Tuesday 
afternoon. Satellite imagery shows the front has not quite formed 
yet but models indicate that frontogenesis will occur tonight as the 
trough approaches. GFS/NAM/ECMWF agree on bringing the front down to 
tofino (cyaz) at 18z/11 am and then just east of Puget Sound sound at 00z/5 
PM. The front will be narrow and the system fast moving so this 
should be a quick shot of rain...starting on the north coast just ahead 
of the front around 18z. Models show a convergence zone pattern 
setting up over Puget Sound sound behind the front Tuesday evening. Models 
also show a shot of rain over the north half of the interior and the north 
Cascades Tuesday evening as the upper level trough axis moves 
through. 


Models are all over the place with precipitation amounts. The 18z NAM 
showed very little over The Lowlands outside of 0.2 to 0.3 in the 
convergence zone. The 00z NAM discards the convergence zone and only 
has a few hundredths over The Lowlands. The 18z GFS is similar to 
the 18z NAM. The 12z European model (ecmwf) has 0.5 to an inch over the north half of West 
Washington. All the models hit the north Cascades with 0.5 to an inch. The 
current forecast is more reasonable with about a tenth of an inch 
from Puget Sound sound northward. Quantitative precipitation forecast over the Cascades could probably be 
doubled to at least a half inch...assuming a decent hit from the 
upper trough axis Tuesday night. 


Cold air aloft trailing the upper level trough will lower snow 
levels down to a little above 6000 feet late Tuesday night over the 
north and central Cascades. But precipitation will be mostly over by then 
so at best there may be up to an inch of snow over the north Cascades. 


Precipitation will be over for The Lowlands by late Tuesday night...but 
increasing SW onshore flow ahead of the front will ensure that the 
lower air mass remains moist through Wednesday morning. Rapid drying 
aloft behind the trough will help skies clear out for sunny 
conditions Wednesday afternoon. The air mass will remain cool so 
highs will only warm up a little to around 70. 


An upper level ridge offshore will build east over the region on 
Thursday. Onshore flow Wednesday night will be negligible or even 
weakly offshore...so with a warming air mass Thursday and little or 
no morning stratus to get in the way...maximum temperatures will warm into the 
lower 70s north to upper 70s SW interior. Kam 


Long term...previous discussion from the 3 PM afd...Friday and 
Saturday look like the warmest days of the week with high pressure 
aloft in control. The ridge will begin to weaken on Saturday but 
that is not expected to have much impact on temperatures or cloud 
cover. 


It looks like there will a marine push Saturday night with an upper 
trough moving over the area on Sunday and Monday for cooler and 
cloudier weather with a chance of showers at times. The models are 
not in good agreement with these details however. Schneider 


&& 


Aviation...low level onshore flow continues across western Washington 
tonight. Low clouds will fill in by morning with MVFR conditions 
expected. A cold front will bring rain to the coast and north 
interior Tuesday morning...with showers spreading into the interior 
during the afternoon. The trailing upper level trough will bring 
more showers to the interior and Cascades Tuesday night. 33 


Ksea...low clouds developing overnight with MVFR conditions 
expected. Surface winds are light northerly...but will flip back to 
southerly by 18z Tuesday. Expect showers in the vicinity Tuesday afternoon 
and evening. 33 


&& 


Marine...onshore flow will continue across western Washington tonight - a 
Small Craft Advisory remains in effect for the central/east Strait 
of Juan Delaware fuca. Onshore flow will increase behind a cold front Tuesday 
afternoon with gale force winds possible over the coastal waters and 
through the Strait. Onshore flow will ease late Tuesday night. High pressure 
over the NE Pacific will maintain onshore flow through Wednesday. Northerly 
flow will prevail Thursday and Friday as low pressure forms along the coast. 33 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory central and eastern Strait of Juan Delaware fuca. 
.Gale watch coastal waters...Central and eastern Strait of Juan 
Delaware fuca Tuesday afternoon through Wednesday morning.
