NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
835 am 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. Look for a weak cold front to sweep across the area 
later this morning. A slightly stronger front is expected to impact 
the region on Sunday. 


&& 


Short term...just in time for the Labor Day Holiday weekend and 
associated outdoor events...a change in the weather pattern. More 
zonal flow across the northern Pacific with a healthy 120 knot jet 
and progressive pattern. An upper trough was approaching 130w this 
morning with the associated baroclinic zone moving onshore at this 
hour with some embedded showers. This system is timed to move 
through the rest of western Washington and into the Cascades by midday. 
NESDIS noted that the source of this moisture originated from Japan 
back on August 21/22. 


The low level onshore flow pattern was also supporting a weak Puget Sound 
sound convergence zone this morning with some light rain/drizzle. 
Issued a Nowcast for this morning precipitation. 


The next shortwave is apparent on water vapor satellite imagery near 
170w that the forecasts bring onshore Saturday PM for another surge of 
showers. Then the next shortwave is near 165e that is due to arrive 
Sunday for more showers. 00z forecasts had some timing differences on 
these systems. Will see what the 12z guidance does for further 
fine-tuning...yet the NAM is Saturday PM and again Sunday PM. 
Daytime temperatures should remain just a bit below seasonal averages. Less 
than sunny Labor Day weekend forecast looks on track. Buehner 


Long term...previous discussion...it appeared that the region will 
be more under the influence of an upper ridge on Monday. Beyond 
Monday...confidence in the forecast was somewhat low. It looks like the 
the medium range solutions might be leaning toward holding onto an 
upper trough over the area longer than the previous runs. Due to lack 
of confidence...the only changes made to the extended were to blend 
better with neighbors. NC 


&& 


Aviation...cloudy with a weak cold front crossing western Washington today. In 
some areas the ceilings are rather low. Visibility will be locally reduced in 
some areas of light rain or drizzle. Low level onshore flow will 
continue tonight and Saturday. The flow aloft is westerly. 


Ksea...morning low clouds should lift up in the afternoon...however 
the Puget Sound sound area might see a period of light rain or drizzle 
with the very weak front that will be over the area later this 
morning and afternoon. 


&& 


Marine...a weak cold front will cross western Washington today. Onshore 
flow will 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.
