NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
232 PM PDT Tuesday Jul 7 2015 


Synopsis...the persistent ridge of high pressure responsible for 
the early July heat wave will gradually weaken this week as onshore 
flow strengthens a bit. An upper low off California may drift far 
enough north this week to bring thunderstorms to the Cascade crest 
in Lane County Wednesday afternoon...and to the rest of the Cascades by 
Thursday. Temperatures will cool down closer to seasonal normals by the 
end of the week as a trough of low pressure approaches the coast. Expect 
this cooling trend to continue into the weekend...with possible 
precipitation expected especially Sunday. 
&& 


Short term...tonight through Friday...morning marine stratus was 
quick to burn off this morning with just a few spots of marine 
stratus lingering over the north Oregon coastline...and a few high clouds 
trailing across the central portion of the County Warning Area this afternoon. 
Visible satellite imagery shows plenty of convective activity over 
the south Oregon Cascades and over the eastern slopes of the 
Cascades...but the storms will continue to drift eastward given 
easterly flow aloft this afternoon and evening. 


Just as expected...temperatures so far this afternoon are cooler due 
to the marine air push last night. Onshore flow persists...and are 
expecting high temperatures to peak near 70 along the coast and in 
the upper 80s inland. Gradients slightly weaker this afternoon 
compared to yesterday afternoon...not expecting as strong of a marine 
push tonight. May see some brief low stratus early Wednesday morning 
pushing further along the Columbia River and impacting Clark County 
and the north Willamette Valley...but it should burn off faster than 
this morning. 


12z models continue to weaken the upper level high prevailing over 
the Pacific northwest tonight as the upper low off the California coast 
pushes closer to the central California coast. As the upper low pushes into 
central California midday Wednesday...we could see some thunderstorms triggered 
over the Cascades Wednesday afternoon and evening. Had a tough time 
deciding how far north the threat for thunderstorms would travel... 
but could not rule out a thunderstorm or two over the S Washington 
Cascades either so went ahead and put in a slight chance of 
thunderstorms over our entire Cascade zones...mainly focused on the 
crest of the Cascades. 


Models show the circulation around the California low opening up some by 
Thursday...developing a more easterly middle and upper level flow that will 
spread increased instability across the SW Washington and northwest Oregon 
Cascades for a better chance of thunderstorms into late Thursday night. 
Currently have a chance of thunderstorms over the Cascades for 
Thursday...and possibly extending over the Cascade foothills. An upper low 
over Alaska starts to extend south across the NE Pacific...as the 
upper low to the south moves inland Friday. The threat for thunderstorms 
over the Cascades continues Friday...but expect a deeper marine push Friday 
morning and much cooler temperatures Friday. Overall have dropped 
temperatures by a few degrees. 


Long term...Friday night through Tuesday...relief from the heat has 
arrived for the extended period...with a bonus batch of precipitation 
expected over the weekend. An upper level trough will approach the 
region late Friday night into Sat...increasing onshore flow and bringing 
cooler temperatures through early next week. 12z models show a decent 
threat for showers late Sat and particularly sun when the upper 
trough axis becomes slightly more negatively tilted...a good 
indicator we would also see some possible convection over the 
forecast area. Overall high temperatures finally return back near 
normal...meaning coastal highs will be in the middle 60s and inland 
highs right around 80. So far...our coolest temperatures look to be 
either next Monday or next Tuesday...with our first below normal high 
possible for Tuesday. /27 


&& 


Aviation...VFR conditions expected with only a few high clouds 
this afternoon and evening. Stratus has dissipated along the 
immediate coast as winds shift to more northwesterly. 
However...expect stratus to redevelop along the coast 04-07z and 
spread inland. Expect stratus to move through the Columbia River 
gap reaching the northern Willamette Valley after 12z. MVFR stratus 
likely reaching keug 13z-16z. 


Instability will continue over the Lane County Cascades for late 
afternoon and evening thunderstorms today and Wednesday. 


Kpdx and approaches...VFR. Low MVFR ceilings expected to develop 
tonight and Wednesday 11z-18z. Schneider 


&& 


Marine...weak surface gradients will continue today as flow 
slowly shifts to the northwest this afternoon and evening. With 
little wind to generate wind waves and fresh local swell from the 
northwest and the distant swell from the southwest are nearly 
equal influence. So there will be several swell trains but bottom 
line is that waves will be fairly low over the next several days. 
By Thursday the southwest swell should dominate as surface winds 
shift to the southwest ahead of developing trough. Schneider
