NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
915 PM PDT Thursday Oct 30 2014 


Synopsis..steady rain associated with a moist frontal boundary has 
pushed inland this evening. The stalled front will continue to 
produce rain overnight into Friday morning...with the heaviest rain 
becoming focused over the Cascades. The dissipating front will push 
east of the Cascades by late morning...with showers remaining Friday 
afternoon behind the front. Expect showers to contain brief heavy 
rain...small hail and possibly some thunder. Showers should begin to 
taper off during the evening hours for those trick or treating. Some 
showers may linger into Saturday...before light rain spreads back 
across our northern zones Sunday ahead of another wet system on tap 
for late Monday and Tuesday of next week. 
&& 


Short term...tonight through Monday...water vapor satellite imagery 
shows a moist frontal system spreading abundant moisture into the Pacific 
northwest. A shortwave rotating around the parent upper level trough on the 
southeast side of the low is slowing the baroclinic zone and pivoting it 
from a NE-SW orientation to a north-S orientation. A band of moderate to 
heavy precipitation ahead of the cold front spread onto the coast 
this afternoon and has pushed slowly inland this evening. There is 
still subtropical moisture feeding into this system...with AMSU 
derived satellite showing 1 to 1.2 inches of precipitation over 
western Oregon...which is significantly above normal. The surface 
cold front moved onshore over the past several hours...but appears 
to have weakened and lost some definition as it passed over the 
Coast Range. The steadier frontal rain has shifted east and is now 
focused over the Willamette Valley and Cascades...while there is a 
back edge to the precipitation band showing up behind the front 
along the coast and northern Coast Range. Another interesting 
development this evening was a line of thunderstorms that developed 
over the southern and central Oregon Cascades...extending into Lane 
County. The latest runs of the short term rap model showed a strong 
band of low level frontogenesis in this region...which would seem to 
explain the thunder. Tracking the rap over the next few hours...it 
appears that the forcing weakens and moves east of the Cascades 
after midnight. Added thunder to the forecast earlier this evening for 
the Cascades south of Montana Hood...with the threat ending after 06z. 


The focus of the heaviest precipitation will shift mainly to the 
Cascades and foothills overnight...with plenty of showers continuing 
behind the front. The front should dissipate and move east of the 
Cascades by middle to late morning tomorrow. Behind the front...a 
significantly colder and somewhat unstable air mass will 
spread into the area. Expect plenty of showers to develop in this 
Post frontal air mass with the brief heavy rain and small hail 
possible as the cold upper trough moves through the area. Based on 
the instability apparent on satellite underneath the upper 
low...cannot rule out a few rumbles of thunder near the coast...or 
over the interior during the late afternoon. Shower activity should 
decrease significantly moving into Friday evening. As the colder air 
mass sets in behind the front...snow levels will drop into the 4500 
to 5000 feet range late Friday into Saturday. Accumulations should 
remain fairly light and below advisory criteria...though motorists 
traveling over the higher Cascade passes including santiam and 
Willamette should be aware of the potential for at least enough snow 
to impact travel late Friday evening into early Saturday. 


The upper trough finally slides into the Great Basin on Sunday and 
showers end as some weak ridging develops over the Pacific northwest ahead 
of the next system. Some light rain may develop over the northern 
zones as a weak warm front may clip the region. More steady rain 
increase late Sunday or early Monday as the next frontal system 
approaches. Pyle/Cullen 
&& 




Long term...Monday through Thursday...a stronger frontal system 
approaches the region by Monday bringing more widespread rainfall. 
Models are in reasonable agreement with a system approaching...but 
significant differences do remain in terms of the location and 
amounts of precipitation. Some indication that some subtropical 
moisture be associated with this system...though the pattern does 
appear to stay a bit progressive in nature. Therefore...increased 
probability of precipitation 
through midweek as another wet week appears in store. Cullen 
&& 


Aviation...a cold front appears to have somewhat stalled and is 
petering out over the Willamette Valley this evening. Rain is 
beginning to transition to a more showery nature with MVFR to VFR 
ceilings. With near calm winds at the coast...could see some MVFR visible 
develop through at least Friday morning. More uncertainty inland 
due to seemingly fizzling front. At this point it doesn't look 
like a significant wind shift will probably occur and if moisture 
lingers...could see another morning with IFR or even LIFR ceilings 
around sle and eug. Showers will continue through Friday with a 
small chance of thunder mainly during the afternoon hours but 
confidence is too low to mention at this point. 




Kpdx and approaches...with front not making a clean sweep through 
the area...MVFR ceilings may linger through the overnight hours. 
Slight chance of thunder Friday afternoon. VFR conditions dominant 
by about 18z Friday outside of any storms. Bowen 


&& 


Marine...winds have dropped to 10 knots or less behind the front 
this evening. With swell continuing to decrease...conditions will 
remain benign outside of the Columbia bar tonight and Friday 
morning before west-northwest swell increases seas to at least near Small Craft Advisory 
criteria Friday evening and overnight. Raised seas to around 10 feet 
based on latest model guidance...but seas forecast is somewhat 
uncertain and borderline for Small Craft Advisory so will let midnight shift 
reassess and issue if necessary. Could see a couple of storms 
Friday afternoon with associated localized gusty winds. Winds 
overall will shift southerly on Friday and increase a bit with 
gusts less than 20 knots. Bowen 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for rough Columbia River bar until 1 am 
PDT Friday. 


Small Craft Advisory for rough Columbia River bar from 10 am to 
2 PM PDT Friday.
