NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
955 PM PDT Thursday Aug 28 2014 


Synopsis...low level onshore flow will help maintain marine 
cloudiness in much of western Washington the next few days. A 
Pacific weather system in the northeast Pacific is expected to move 
onshore later Friday and Saturday bringing some light showers to the 
area. Another system will follow on Sunday. Higher pressure is 
forecast to build for a drier Labor Day before another weak weather 
system with a threat of showers moves onshore by the middle of next 
week. 


&& 


Short term...satellite imagery shows the middle and high level clouds 
associated with a weak shortwave have moved into the Cascades this 
evening. Stratus along the coast has not yet consolidated with kuil 
still clear at 04z while khqm is overcast. Temperatures at 9 PM were 
in the upper 50s to lower 70s. 


00z model solutions showing good consistency with the the previous 
model runs for the first couple of days. Main story for western 
Washington is the warm weather is over with a spell of cooler and 
cloudier weather in store for the next few days. Onshore gradients 
increasing a little overnight in response to the next 
shortwave...currently near 135w...moving eastward. The increasing 
onshore flow will help the stratus along the coast spread inland 
early Friday morning. Dew points are in the middle 50s to lower 60s at 
9 PM so expect some of the stratus to form in place early Friday 
morning as well. Lows tonight in the 50s and lower 60s. 


Shortwave moving through western Washington late morning through 
Friday afternoon with low level onshore flow continuing. Satellite 
imagery shows cloud top temperatures warming with the shortwave 
warming. In addition the parent low of the shortwave is moving 
northeast which is splitting and weakening the shortwave as well. 
Even with the shortwave weakening...it will not weaken enough to 
take a chance of showers out of the forecast on Friday. High 
temperatures will continue to cool on Friday with middle 60s to lower 
70s. 


Low level onshore flow with a chance of showers continuing into 
Friday night. Another weak shortwave arriving on Saturday keeping at 
least a chance of showers forecast. The shortwave on Saturday looks 
to be the strongest of the group. If the model trends continue look 
for the probability of precipitation to be increased on Saturday. 


Yet another shortwave moving through the area sometime later Sunday 
into Sunday night. 00z model consistency both run to run and within 
the models begins to break down on Sunday with the NAM keeping the 
faster solutions of the previous runs with at least a chance of 
showers over the area by Sunday afternoon. The 00z GFS has slowed 
the shortwave down moving it through the area late Sunday night into 
Monday morning. With the lack of consistency will stay with the 
chance probability of precipitation forecast. 


Current forecast have the trends covered. No update this evening.

Long term...the forecasts diverge quite a bit starting on Tuesday with 
the GFS clearly the outlier Wednesday and Thursday. The CMC and 
European model (ecmwf) both dig the next trough into the Pacific northwest later on Tuesday 
into Wednesday and shift it inland by Thursday while the GFS lags 
behind. Agree with the pmd discussion and have the first week of 
school forecast increasing the threat of showers again later Tuesday 
into Wednesday with drier conditions Thursday. Daytime temperatures do not 
really get much of chance to recover from Holiday weekend readings.

Aviation...low level onshore flow continues across western Washington 
tonight. The flow aloft is westerly. Low clouds will fill in 
overnight with MVFR conditions expected. A weak cold front will 
cross western Washington on Friday with isolated to scattered showers across 
the region. Low clouds will lift during the afternoon and evening 
for VFR conditions. 33 


Ksea...low clouds will lower into MVFR range overnight. Surface 
winds will remain light southerly. Expect showers in the vicinity on Friday 
as a cold front crosses western Washington. Ceilings will raise to around 3000 
feet Friday afternoon. 33 


&& 


Marine...Post-frontal onshore flow continues across western Washington 
tonight with Small Craft Advisory winds through the central and east 
Strait of Juan Delaware fuca. Another weak cold front will cross western 
Washington on Friday with onshore flow increasing Friday night. Will likely see 
another round of Small Craft Advisory winds through the Strait. Then 
another weak surface trough will move inland on Sunday. High pressure 
over the NE Pacific will maintain onshore flow across western Washington through 
early next week. 33

Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory central and east Strait of Juan Delaware fuca.
