NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
421 am PDT Friday may 22 2015 


Synopsis...the marine layer will deepen Friday and move 
the threat for thunderstorms over and east of the Cascades by Friday 
evening. Strong onshore flow will continue through Saturday...then 
weaken a little Sunday. Another upper low looks like it will approach 
the area early next week...generally bringing continued shower 
chances. 


&& 


Short term (updated)...observations Show Low stratus has moved in 
across the forecast area early this morning...signaling the arrival 
of the marine layer which will make it difficult to get any further 
thunder. In addition...latest radar trend shows weakening showers 
although do not expect them to comletely dissipate. Have eliminated 
thunder from the forecast for The Lowlands today but will keep a 
slight chance in for the Cascades this afternoon. 


There will be little change in the weather pattern Friday night and 
Saturday as the upper low remains over the region. A deep marine 
layer will maintain cloudy skies and possibly produce drizzle 
Saturday morning. The low will move further inland Saturday 
afternoon...but still may produce some mountain showers. 


Models still showing large differences Sunday and beyond. 
If the European model (ecmwf) is correct...there would be stronger onshore flow sun 
with less afternoon sun. The GFS and NAM have less onshore flow. In 
any event...general conditions look stable...with any shower threat 
confined to northern Cascades. Bowen/tj 


Long term...no significant changes. Previous discussion 
follows...Sunday night through Thursday...GFS and European model (ecmwf) both show an 
upper level low or trough sitting over Oregon and Washington through 
Tuesday. Main model difference is that the GFS maintains a closed 
feature...keeping it over SW Washington...while the European model (ecmwf) has more of an open 
trough a little more east than the GFS. Regardless of which model 
verifies best...the main sensible weather for the County Warning Area would be 
continued onshore low-level flow with the best threat of 
showers...albeit small...over the Cascades. The GFS holds the upper 
low somewhere over southeast Washington Wednesday...while the European model (ecmwf) has a more progressive 
northwesterly flow aloft. Have gone with slight chance probability of precipitation for the Cascades 
Wednesday...but if the GFS is more right...then it would be dry. Too much 
uncertainty to totally disregard any precipitation threat. Weishaar 


&& 


Aviation...as onshore flow continues...the low end MVFR to IFR ceilings 
along the coast are expected to slowly lift up into an MVFR ceiling 
today. Expect the MVFR ceilings to spread into inland valleys this 
morning...affecting valley taf sites by 12z. The inland clouds are 
likely to break up into a scattered cloud layer between 20z and 22z 
leaving inland areas VFR. MVFR ceilings are likely to remain along the 
coast through 10z tonight...and spread back into inland valleys 
again after 09z. 


Kpdx and approaches...MVFR ceilings expected to spread in between 09z 
and 11z this morning...then break up again to VFR conditions between 
20z and 22z this afternoon. Onshore flow will again spread marine 
clouds with MVFR ceilings back inland after 09z tonight. 


&& 


Marine...persistent high pressure well offshore will keep below small 
craft winds out of the northwest through early next week. A fresh swell of 
5 to 6 feet will also continue out of the west-northwest. 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...none.
