NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
833 PM PDT Thursday Sep 18 2014 


Synopsis...a weak disturbance will move across the area overnight 
into early Friday morning. Look for high pressure aloft to begin 
building over the region on Friday. Strong high pressure aloft 
along with low level offshore flow will result in well above 
normal daytime temperatures this weekend. 


&& 


Short term... 
zonal flow aloft will prevail across the area tonight. A weak 
short wave trough embedded in this flow will bring precipitation to mainly 
the northern part of the County Warning Area overnight into Friday morning. Klgx 
Doppler radar currently showed the leading edge of the rain shield 
not too far off the north coast. 


An upper ridge will begin building over the region on Friday for 
clearing skies. The ridge will amplify further this weekend. This 
combined with low level offshore flow will result in well above 
normal daytime temperatures across much of the County Warning Area. 


Long term from the previous discussion... 
the upper ridge axis will move over the intermountain west on Monday 
and this will allow a weakening occluded front to approach the 
coast. This front will likely dissipate as it moves onshore. The 
main impact will be cooler and cloudier weather Monday and Tuesday. 


Beyond Tuesday...a stronger system will impact the Pacific northwest 
during the latter part of the extended period...resulting in below 
normal daytime temperatures and breezy conditions. This system is 
expected to remain off the coast through Thursday. 


&& 


Aviation...westerly flow aloft tonight and Friday. A weakening 
front will reach the coast Friday morning and dissipate over the 
area later in the day. Weak onshore flow will continue with high 
pressure along the coast and lower pressure inland. Air mass moist 
and slightly unstable. There will be a mix of low and middle clouds 
across the area tonight. The trend should be for low clouds to 
increase overnight. 


Ksea...3000-4000 foot ceilings this evening should lower to 
1000-2000 feet tonight. Southerly wind 4-8 knots. Schneider 


&& 


Marine...weak high pressure will be over the coast with lower 
pressure inland tonight and Friday. Small Craft Advisory west winds 
are possible for the central and eastern Strait through the early 
morning hours Friday but the event looks marginal at best. 


A dissipating front will move through the waters on Friday. Offshore 
flow will quickly develop Friday night and continue through Sunday 
morning as a trough builds north along the West Coast. Small Craft 
Advisory east winds are possible for the western Strait Sunday 
morning. 


A weakening trough will reach the coastal waters Monday. A stronger 
frontal system well offshore will be approaching from the west on 
Tuesday. Schneider 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory in effect until 2 am Friday for the 
central and eastern Strait of Juan Delaware fuca.
