NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
300 PM PDT Friday Aug 29 2014 


Synopsis...low pressure aloft will dominate the weather pattern 
over the region through this weekend for cool and unsettled 
conditions. A series of weather systems are expected to move onshore 
through the Holiday weekend. Another system is forecast to move 
onshore Tuesday before higher pressure aloft builds for a warming 
and drying trend toward the end of next week. 


&& 


Short term...zonal flow pattern across the northern Pacific with a 
decent jetstream for late August. Peak of the jet near the dateline 
was about 135 knots early this afternoon. So embedded systems should 
move right along and that is what the latest forecasts show through the 
Holiday weekend and into next week. 


The offshore upper trough was moving inside 130w this afternoon and 
should move onshore tonight with limited light showers. The 
associated very weak cold front moved inland earlier today and 
produced quite light amounts of rain - mainly trace amounts. 


The next embedded shortwave had progressed to just inside 160w early 
this afternoon. Forecasts are similar in bringing this system onshore 
Saturday PM for another increase in showers. The following shortwave 
was moving across the dateline and again the forecasts are rather 
similar in bringing this one onshore late Sunday for another surge 
of showers...perhaps being the wettest of the series in a relative 
manner. 


Amounts in general should be rather light throughout the Holiday 
weekend with the greatest totals in orographic mountain areas. In 
addition...each system may include a Puget Sound sound convergence zone as 
well - noted in the mesoscale model output and in the graphical 
forecasts. Heights rise Monday for a drying trend with lingering 
showers mainly in the mountains and convergence zone. Daytime temperatures 
should remain a bit below seasonal averages. Buehner 


Long term...the medium range guidance - foreign and domestic - has 
generally come together regarding days 4 through 7 of the forecast 
period. All dig a shortwave into the Pacific northwest as the zonal flow 
pattern amplifies through the week. Precipitation with the shortwave 
arrives Tuesday and exits by late Wednesday - a bit quicker than 
previous guidance. Then rising heights aloft and low level flow 
turns more offshore as thermally induced low pressure noses north 
from northern cal and western Oregon. There has been some 
speculation that perhaps we may not see 80 degrees again this year. 
This pattern change may produce some 80s when it is all said and 
done. 


Of interest...ksea has had 39 days of 80 degrees or better this year 
making it the 6th most number of warm days on record. The most is 47 
days of 80 or warmer set in 1958. In sharp contrast...1954 had only 
2 days of 80 or better - whew! Buehner 


&& 


Aviation...skies are mostly cloudy over western Washington as a weak cold 
front breaks up over western Washington this afternoon. With a deep marine layer 
in place tonight...low clouds will spread out overnight...then lift 
and break up in typical fashion Saturday. Low level onshore flow 
will continue through Saturday. The flow aloft is westerly. 


Ksea...the clouds were breaking up this afternoon as the weak cold 
front dissipated. With a marine layer in place low clouds will 
redevelop overnight and then break up again midday Sat. Pressure 
gradients are light and the wind this evening may turn from SW to 
just light and variable for a time. 


&& 


Marine...a weak cold front broke up over western Washington this afternoon. 
Onshore flow should increase behind the front this evening and the 
forecast is for Small Craft Advisory winds in the central and east 
Strait of Juan Delaware fuca. 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. 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory in effect until 5 am Saturday for the 
central and eastern Strait of Juan Delaware fuca.
