NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
225 PM PDT Monday Sep 1 2014 


Synopsis...a weakening front will keep some clouds along the north 
coast this evening...otherwise it will be mostly clear. An upper 
level trough will move across the region Tuesday into early 
Wednesday brining cooler and cloudy weather. This system will also 
bring some light rain to southwest Washington and the far northern 
part of northwest Oregon Tuesday afternoon and Tuesday night. An 
upper level ridge combined with low-level easterly winds will result 
in sunnier and warmer weather for the latter part of the week. 
Onshore flow will return next Sunday. 


&& 


Short term...tonight through Thursday...a weakening front just off 
the Washington/or coast this afternoon keeping a persistent area of clouds 
over the north coastal area...mainly from about Tillamook northward 
this afternoon. Webcam imagery at Astoria this afternoon also showed 
some spotty light drizzle occurring from time to time. Elsewhere... 
lots of sunshine giving way to a splendid Labor Day. 


An upper level trough off the British Columbia coast will drop south 
towards the Pacific northwest later tonight. The marine layer should deepen 
tonight and with increased onshore flow tonight. Thus...expect 
marine clouds to push farther inland Tuesday morning. A weak front 
associated with the upper level trough will move across the northern 
part of the region Tuesday afternoon/evening. The front will 
produce some light rain along the north coast/Coast Range and part 
of the inland area. Best chances of measurable rain will be in 
southwest Washington...but the northern Willamette Valley and adjacent 
foothills and north Cascades will be on the southern end of the 
front and could get alittle rain Tuesday eve/night. There will be 
another deep marine push Tuesday night with a cloudy start to the 
day on Wednesday. The upper trough and increase in clouds will keep 
the temperatures below normal Tuesday and Wednesday. 


High pressure will rebuild over the region Thursday. A fairly strong 
thermal trough will also build northward along the coast. This will 
result in offshore flow...clear skies...and warmer temperatures 
the latter part of the work week. Tw 


Long term...Friday through Monday...a weak...positively-tilted 
trough will move through our area late this week. Not only is 
moisture limited for the passage of this system...but any 
precipitation that does develop should be east of the Cascade 
Ridge...outside of our area. Late this weekend the 
GFS...ECMWF...and dgex all are suggesting a longwave trough will 
move onshore bringing a chance for some rainfall Sunday night or 
Monday. Disagreement between models on timing and because of how far 
out this system is in the forecast period...there is a lot of 
uncertainty with this system. Kept probability of precipitation the same as they capture 
this uncertainty well. -McCoy 
&& 


Aviation...a weak disturbance will be passing by through western 
Washington and brush extreme northwest Oregon today for some for 
mostly VFR ceilings along the South Washington and north Oregon coasts 
and inland near the Columbia River to kkls or so. The lowest ceilings 
will be along the north coastal areas. Farther inland there may be 
a few ceilings near the mountains but less chance in the valleys. The 
surface pattern suggests the central Oregon coast and the south 
Willamette Valley will tend to stay clear this afternoon and 
evening. With plenty of clouds upstream over the NE Pacific... 
expect MVFR ceilings to push onto the coast overnight tonight and 
spread inland to kpdx and possibly a bit south by Tuesday morning. 
Another more organized front is expected to spread in from the 
northwest Tuesday with MVFR ceilings or perhaps high IFR and some 
light rain on the coast...approaching kpdx by 00z Wednesday... 
which is 5 PM Tuesday. 


Kpdx and approaches...VFR conditions today. May see some VFR ceilings 
for a time late this afternoon and evening around 5000 or 6000 
feet. There is a decent chance MVFR conditions will impact the 
terminal towards 12z Tuesday. Some VFR ceilings and possibly a shower 
are possible late Tuesday. Pt 
&& 


Marine...a weak disturbance passing by to our north briefly 
turned the winds in our northern waters to light southerly...but 
then weak high pressure will briefly build back in tonight and early 
Tuesday for north to northwest flow along the entire coast...which 
may give Small Craft Advisory threshold gusts to our central 
Oregon waters mainly tonight. Another slightly stronger frontal 
band is forecast to move into the waters midday Tuesday and 
onshore Tuesday evening...with the main effect being some 
moderate northwest winds behind the front that may give some gusts above 
20 knots as well especially in the outer waters. The thermal trough 
begins redeveloping in northern California Wednesday...with Small 
Craft Advisory threshold northerly winds beginning to spread north 
along the central Oregon coast late Wednesday. The winds will then 
spread northward through all the waters Thursday and Friday as 
the thermal trough continues to builds farther north along the 
coast. Winds Thursday afternoon and evening will be on the high 
side of the Small Craft Advisory range. 


Seas may get close to 10 feet in the northern waters from the 
northwesterlies Wednesday...and possibly again around 8 to 10 feet 
late Thursday and Thursday night from the northerlies due to the 
northward building thermal trough. Pt 
&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds from 5 PM this afternoon to 
3 am PDT Tuesday for coastal waters from Cascade Head or to 
Florence or out 60 nm.
