NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
314 am PDT sun Aug 31 2014 


Synopsis...clouds...cooler temperatures...and a few lingering 
showers today on the backside of a departing trough. There will be 
slight warming Monday with dry weather as a weak upper ridge moves 
over the region. Another upper level trough will bring a return of 
cloudy and cool weather Tuesday and Wednesday. Offshore winds and 
warmer temperatures expected late in the week. 


&& 


Short term...today through Wednesday...water vapor imagery shows the 
Pacific northwest sandwiched between an upper ridge over the east Pacific 
and an upper trough over the inter-mountain west. Radar imagery shows 
weak echos off shore and isolated showers are possible for the 
coast...Coast Range and Cascades early this morning. Infrared imagery 
shows areas of middle-level clouds offshore that will move over northwest 
Oregon throughout the day...and help maintain seasonably cool weather 
today. 


The upper jet that helped produce lift over northwest Oregon on Saturday 
has shifted to the north...resulting in a drier northwesterly flow 
for the region. The storm track is also further north...such that the 
approaching shortwave troughs embedded within the northwest flow...will 
remain north of the Portland forecast area the next couple of days. 
Therefore the shortwave that was expected to bring rain tonight and 
Monday to the Portland forecast area will most likely not produce any 
rain over northwest Oregon. Have therefore reduced probability of precipitation for tonight and 
Monday across the region. 


Weak upper level ridging will attempt to build in Monday...and the 
daytime temperatures will warm closer to the seasonal normals. This 
warming will be short-lived as another upper trough dropping south 
from the Gulf of Alaska will bring additional cloudy and seasonably 
cool weather for Tuesday. Most of the showers with this trough will 
remain in central and northern Washington...but there may be a few 
light showers across SW Washington Tuesday evening. Otherwise...a 
deep marine layer will likely result in marine clouds pushing far 
inland Wednesday morning.Tj 


Long term...Wednesday night through Saturday...the upper trough 
moves inland Wednesday night. An upper level ridge noses into western 
Canada and northern Washington Thursday...but a low off of California 
will maintain lower pressure over northwest Oregon. High pressure to the 
north and east...with low pressure to the south and southeast will 
result in offshore winds across the Portland forecast area. Expect 
and increase in sunshine and afternoon temperatures Thursday through 
next Saturday. Tj 


&& 


Aviation...weak pressure gradients across western Oregon and a 
moist...but relatively unstable lower atmosphere should generally 
keep conditions VFR inland...with periods of IFR and MVFR conditions 
along the coast. However...there should be a period of VFR conditions 
along the coast this afternoon...but timing and duration remains 
uncertain. There is also a chance MVFR conditions will develop for 
a few hours centered around 15z this morning...but confidence is low 
at this point. Otherwise...additional IFR conditions will likely 
redevelop along the coast Sunday night...but inland penetration 
should be limited. 


Kpdx and approaches...there is a chance MVFR conditions will develop 
for a couple hours around 15z Monday...but otherwise...expect VFR 
conditions through 12z Monday. /Neuman 


&& 


Marine...high pressure today will give way to a weakening front 
on Monday. Few marine impacts are expected. High pressure will 
then return to the northeast Pacific with thermal low pressure 
strengthening over interior northern California. This will place 
the waters in a familiar this Summer with periods of gusty northerly 
winds. Expect seas to fluctuate generally between 4 and 7 feet with 
the predominant swell remaining around 9 to 10 seconds out of the 
northwest this week. /Neuman
