NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
230 PM PDT Friday Jul 31 2015 


Synopsis...an upper level ridge of high pressure over the region 
will continue to bring warm temperatures to the inland areas through 
the weekend. The ridge of high pressure will move east of the 
region early next week and bring a gradual cooling trend. Monsoonal 
moisture from the south will bring a slight chance of a shower or 
thunderstorm to the Oregon Cascade crest late in the weekend and 
early next week...but confidence remains low in the thunderstorm 
threat. 


&& 


Short term...today through Tuesday. As of 230 PM...inland 
temperatures are well into the 90s across the region and remain on 
track to reach or exceed the century mark again this afternoon. Some 
locations in the southern Willamette Valley will meet or exceed 
yesterday/S high temperature readings. The coastal strip remains 
quite pleasant with light onshore flow. 


Satellite imagery shows some middle-level moisture slowly drifting 
northward from nocal and the Great Basin with cumulus clouds 
building along the Cascade crest in Lane County. The steering flow 
remains out of southwest so any cloud build ups will remain on or 
east of the Cascade crest.As the upper level ridge axis begins to 
shift east during the weekend...the middle level steering flow becomes 
more southerly. This will bring an increase in middle and high level 
clouds to the area. Model soundings show some of the initial 
moisture will likely be too high to produce elevated thunderstorms 
on Saturday...but this may begin to change late Saturday night or 
Sunday across eastern Lane and Linn counties. Confidence remains low 
though...as models do not really show much in the way of a middle level 
trigger. 


The increase in middle and upper level clouds combined with the 
strengthening of the low level onshore flow will bring a slow 
downward trend in temperatures over the next several days. 
Temperatures will only decrease a few degrees each day...but inland 
daytime maximum temperatures should fall below 90 degrees by Tuesday. Tw 


&& 


Long term...a few model discrepancies start off the extended 
period. Both the 12z GFS and European model (ecmwf) show an upper level trough 
approaching the region from the northwest late Monday...but the 
European model (ecmwf) deepens the low by early Tuesday whereas the GFS just skims 
the top of the Pacific northwest early next week. The models then 
have timing issues on bringing a trough over the area late next 
week. Overall...we will see a general cooling trend through the week 
with high temperatures returning back to normal. Could see a threat 
for Cascade thunderstorms Monday evening and again Tuesday afternoon 
and evening. We may also see some showers clip the SW Washington and 
northwest Oregon coast by Wednesday and Thursday if the European model (ecmwf) solution 
comes to fruition. /27 


&& 




Aviation...inland VFR will prevail for the next 24 hours although 
there will be areas of cumulus and smoke mainly above fl080 near 
and along the Cascades. Coastal areas will see a shallow region of 
low stratus begin to push inland as the sea breezes mature this 
afternoon and early evening. Also expect gusts mainly 20 to 25 knots 
there with localized 25 to 30 knots closer to Florence. Planning on 
the coastal stratus/mist will return tonight as winds ease overnight. 


Kpdx and approaches...VFR conditions. /Jbonk 


&& 


Marine...high pressure lingering over the offshore waters through 
sun will keep north winds blowing over the coastal waters through the 
weekend. Expect the winds to pick up some later today as the 
trough of low pressure over western Oregon moves further 
inland...resulting in wind gusts rising into the 20 to 25 knots range 
from late today into sun. Seas will remain dominated by north to northwest 
wind waves and fresh swell...keeping seas steep and at times 
necessitating an advisory for hazardous seas mainly during late 
afternoon to overnight hours. 


The high pressure weakens by late sun and Monday...allowing a weak cold 
front to move S into the waters late Monday. System looks weak enough 
to allow winds and seas to drop below small craft criteria.
