NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
856 am PDT Tuesday Sep 2 2014 


Synopsis...an incoming front will bring increasing clouds and a 
chance for light rain showers to mainly southwest Washington and 
extreme northwest Oregon late this afternoon and evening. Morning 
clouds should once again return Wednesday...and result in one last 
day with temperatures near to slightly below normal. Strengthening 
offshore winds will allow temperatures to rise into the upper 80s 
and low 90s for many inland locations late in the work week. There 
is a chance another storm system could bring a chance for light rain 
showers to the area early next week. 


&& 


Short term...today through Friday...satellite imagery shows a layer 
of marine low clouds stretching from the foothills from Troutdale 
eastward southwestward to Eugene. There is also some low clouds along 
the north coast and near the central coast. 


An upper level trough approaching the Washington coast this morning will 
move southeastward across Washington later today. A trailing front 
will slide southeastward across the northern half of the area late 
this afternoon and evening...resulting in a few light showers across 
southwest Washington...and the west facing slopes of the north 
Oregon Cascades and Coast Range. Rainfall will be quite light with 
this system. However...this system will keep temperatures down a tad 
today and Wednesday...with temperatures topping out near normal to a couple 
degrees below normal. As the front moves through the area...it will 
push the surface high pressure southward into a position that should 
allow marine clouds to develop across much of northwest Oregon 
tonight into Wednesday morning. 


Strengthening high pressure over the northeast Pacific and weak upper 
level troughing over southwest Oregon and northern California...will 
turn middle level winds more northeasterly over the area. This will 
allow thermal low pressure currently over northern California to 
build up the coast late Wednesday into Thursday. This should result 
in temperatures rising into the upper 80s and low 90s for 
the Willamette Valley Friday and Saturday. In addition...poor 
night time relative humidity recoveries and modest east winds across 
the Cascades and Coast Range will enhance fire weather concerns the latter 
part of the week. Tw/neuman 




Long term...Saturday through Monday...no changes...previous 
discussion follows....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...variety of flight conditions across the region this 
morning behind a weak cold front that moved across the area early 
this morning. Much of the interior remains VFR with a scattered-broken deck 
around 4000 feet...though some remnants of a low MVFR stratus layer 
remain along the Columbia River...and south Willamette Valley. 
These may linger a bit this morning and while some areas may 
clear...a scattered-broken layer around 4000 feet may persist through the 
afternoon. Clouds increase this evening as the next front 
moves in...with MVFR ceilings likely and a chance for -ra across the 
northern areas. At the coast...conditions have generally improved 
with local areas of fog/low stratus. As flow becomes more onshore 
may see some ceilings develop along the coastal areas...and will 
again return to low MVFR/IFR this evening. 


Kpdx and approaches...VFR conditions today...with increasing 
clouds late this afternoon with the next weak cold front. MVFR 
ceilings develop this evening with slight chance of rain shower later 
this evening. Cullen 


&& 


Marine...a weakening cold front will move across the waters this 
evening... and may be strong enough to produce some S-SW gusts to 
20 knots along the S Washington coast as it moves onshore. Behind the 
front...winds again shift north-northwest with gusts to 20 knots...but cannot 
rule out a occasional stronger gusts primarily over the northern 
outer waters. 


North-northwest winds will increase for second half of week as high pressure 
strengthens offshore and thermal low pressure extends north from 
California. Gusts 20-25 knots appear likely along the central Oregon 
waters by Wednesday afternoon...then expanding north across the waters on 
Thursday. Winds should ease for Friday and Sat as the offshore high pressure 
weakens. Cullen

Pqr watches/warnings/advisories...
