NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
257 am PDT Wednesday Sep 17 2014 


Synopsis...a low pressure system remains centered off the southern 
Oregon and northern California coast this morning...and will 
continue to send a few surges of light moisture into northwest 
Oregon and southwest Washington today. The low will approach the 
coast this afternoon...and move onshore tonight and Thursday as a 
more organized area of moisture moves onshore tonight. Daytime 
heating will aid the formation of more showers Thursday afternoon as 
the main part of the low moves south into California. Showers will 
decrease Thursday night and Friday as an upper ridge builds in 
behind the low. The upper ridge will be at its strongest this 
weekend as a thermal trough builds up the coast again...for a return 
of dry and much warmer weather. Onshore flow and cooler weather are 
expected to return next week...with possibly a few showers by middle 
week. Onshore flow will keep most of the smoke from the 36 pit and 
deception complex fires over the Cascades and to the east. 
However...high pressure and offshore flow look increasingly likely 
to build over the region this weekend so expect smokey conditions to 
return with inland temperatures possibly approaching 90 degrees 
again. 
&& 


Short term...a low pressure system is centered off the southern 
Oregon and northern California coast this morning. It has spread some 
light moisture and a few showers across parts of northwest Oregon and 
southwest Washington overnight. The models indicate some more light 
moisture and a few showers will continue to spread in from the 
southwest across our forecast area today...though amounts will be 
light. The expected cloud cover will tend to keep temperatures in the 75 to 
80 range again today across the interior. 


The low will approach the coast this afternoon...and a stronger area 
of vorticity and moisture will likely spread in mainly this evening 
and overnight tonight as the low begins to move onshore. Will have 
the highest probability of precipitation during that time with chance in many areas and some 
small areas of likely probability of precipitation especially the Southern Mountain areas. 


The main low center then tends to move south into California as it 
moves inland on Thursday. However there is enough moisture in 
combination with daytime heating for an increase in showers in the 
afternoon from the Coast Range eastward. Have decided to go 
scattered on the shower coverage Thursday afternoon except likely in 
the Oregon Cascades. 


The models show some instability both this afternoon and Thursday 
afternoon in the Oregon Cascades...so have a slight chance of thunder 
in that area both days. 


An upper ridge builds in Thursday night and Friday for drying and 
slowly warming weather. There is enough onshore flow and left over 
moisture for a fair amount of morning low clouds Friday morning... 
that may hang around through much of the day in the mountains from 
about Portland north...finally clearing in the evening. Temperatures will 
start to rise a bit Friday...but the more substantial warming will 
hold off until the weekend. 


Smoke from the 36 pit and deception complex fires will tend to spread 
out to the north and northeast today...then more to the east Thursday 
and Friday. East winds may return this weekend which would bring the 
smoke back into the Willamette Valley again. Tolleson 


Long term...no changes. Previous discussion follows...Friday night 
through Tuesday...the GFS...dgex...and European model (ecmwf) models 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...tranquil conditions continue this morning with light 
winds and variable middle and high clouds providing for VFR conditions 
area wide. Not expecting any fog or low clouds early this morning 
with quite weak onshore gradient...though can not completely 
eliminate a few patches of fog in bays and Coast Range valleys early 
this morning. Will see increasing middle level clouds today along with 
the potential for a few showers. 


Smoke from the 36-pit fire continues to drift to the east and NE. Will 
see smoke continue in East Columbia gorge...Upper Hood River Valley 
and around Montana Hood...with some smoke trapped settling in valleys to east 
and north of the fire. With S winds aloft over next few days...smoke from 
fires over SW Oregon and northwest California will drift north to NE...affecting 
slantwise visibility from Cascades eastward. 


Kpdx and approaches...VFR continues with variable high clouds this 
morning. Increasing middle level clouds today...with ceilings likely forming 
in the 4000-5000 feet range this afternoon/evening with increasing 
chances for a shower or two. Cullen 
&& 


Marine...fairly benign conditions continue over the waters for the 
next few days as weak low pressure will maintain S to southeast wind less than 
15 knots. There will be a mix of wave trains with varying periods... 
from the northwest...west and SW. Expect northwest swell to dominate today at around 
15 seconds. Overall seas running 6 to 8 feet...with highest further 
offshore. 


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 east to NE winds to the waters this weekend with winds possibly 
gusting to 25 knots on Sat and Sat night. Cullen
