NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
245 PM PDT Tuesday Sep 16 2014 


Synopsis...a low pressure system currently well off the Oregon coast 
will move towards southern Oregon and bring a chance of showers late 
Wednesday into Thursday across northwest Oregon and southwest 
Washington. Onshore flow will keep most of the smoke from the 36 
pit and deception complex fires over the Cascades and points east. 
However...high pressure and offshore flow looks increasingly likely 
to build over the region towards the weekend so expect smokey 
conditions and temperatures possibly approaching 90f again across the 
Willamette Valley. 




&& 


Short term...tonight...water vapor satellite imagery shows a large 
shortwave trough located off the California coast...placing the County Warning Area 
under deep south to southwesterly flow aloft. Visible satellite 
imagery shows the first round of middle to upper level clouds pushing 
northward off the Oregon coast and across southwest Washington. 
Doppler radar indicates some light precipitation is falling out of 
these clouds...but suspect this is almost entirely virga. Another 
cluster of virga currently off Cape Mendocino should track along the 
Oregon coast this evening. 


The 36 pit and deception complex fires continue to produce plenty of 
smoke. Continue to check with your state air quality agency for the 
latest air quality observations. Expect valley locations immediately 
down river of these fires like Estacada and Oakridge to experience 
problems with smoke each night and early morning this week. 
Fortunately...west winds each afternoon and evening should disperse 
smoke...especially when the fires are generally most active....to the 
east. 


For Wednesday...models agree the upper level trough and surface low 
pressure currently well off the California coast will shift 
northeastward towards the California/Oregon state line through 
Wednesday evening...before splitting and nose diving into Southern 
California late Thursday. This rather messy pattern will result in 
waves of mainly middle to upper level clouds spreading across the area 
through Wednesday evening. Aside from a few sprinkles from time to 
time...suspect most locations will remain dry based on model 
soundings. Kept a slight chance mention of thunder across our 
southeastern zones Wednesday afternoon and evening where perhaps 
enough middle level instability could generate a lightning strike or 
two...but confidence in this scenario panning out is very low. 


For Thursday...the NAM and GFS suggest a low level surge of 
isentropic lift ahead of the trough axis late Wednesday night into 
Thursday morning may saturate the atmospheric column and result in 
light precipitation across much of the area Thursday morning. Low 
level westerly flow should also aid in wringing out light rain 
across the orographically favorable Coast Range and Cascades. As a 
result...probability of precipitation were nudged upwards during this period into the low 
end likely category along the coast and across the topography...and 
high end chance category for valley locations. Models suggest cloud 
cover will be ample on Thursday...but if we do get any breaks in the 
clouds...it will not take much heating to produce thunderstorms. At 
this point...cloud cover looks pretty solid Thursday so left the 
mention of thunder out of the forecast...but this will be Worth 
monitoring over the next 48 hours. 


Overall...continue to remain nervous that models are too aggressive 
with the moisture and precipitation chances late Wednesday into 
Thursday given the splitting nature of the upper level trough. In 
addition...this will be the first fall like storm system to try and 
break down the longwave ridge...which also does not Bode well. 


For Friday...shortwave ridging moving into the area late Thursday 
into Friday should allow the area to dry out considerably. 
Strengthening thermal low pressure over California on Friday will 
turn winds more northerly...and the area will begin another warming 
trend. /Neuman 




Long term...Saturday through Tuesday...GFS...dgex...and European model (ecmwf) all 
show a return to easterly flow on Saturday which will warm 
temperatures across the area. This warm up will only last through 
Sunday...as winds shift back to the west from an upper-level trough 
and associated cyclone deepening over the Gulf of Alaska. This will 
cool temperatures and bring the marine layer back in at night Monday 
and Tuesday. -McCoy 
&& 


Aviation...light southeast winds have helped clear the marine clouds 
sooner than anticipated this afternoon. Marine stratus with MVFR 
ceilings should fill in along the immediate coast after 0z. Onshore 
winds across central Oregon coast will bring some clouds through 
the coastal gaps near konp early this evening...and up the lower 
Columbia River towards kspb.. light south to southeast winds will 
develop late tonight and prevent the clouds to move much inland. 
Would not be surprised if the marine clouds actually push away 
from the coast early Wednesday morning. There may be a brief period of 
low MVFR for the southern Willamette Valley including keug around 
09z...but forecast confidence is low for keug ceilings. 


Smoke from the 36 pit wildfire will generate MVFR ceilings in vicinity of 
the fire. This smoke should remain mostly over the Cascade 
foothills this afternoon and evening...but may expand its 
coverage when the winds calm late tonight...and possibly impact 
parts of the northern and central Willamette Valley early Wednesday 
morning. 


Kpdx and approaches...VFR today and tonight with a mix of high 
clouds. Tj 


&& 


Marine...fairly benign conditions persist over the waters for 
the next few days as weak low pressure will maintain south wind 
generally less than 15 knots. There will be a mix of wave trains 
with varying periods...out of the northwest...and SW with the overall wave 
heights gradually building tonight. Sea heights of 5 to 7 feet can 
be expected through Thursday. 


High pressure will rebuild over the waters Friday and Sat...with thermal 
low pressure over the coast and coastal waters. This will bring 
another round of north winds to the waters this weekend with winds 
possibly 
reaching Small Craft Advisory levels at times. Tj
