NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
234 am PDT Tuesday Apr 21 2015 


Synopsis...an upper trough will replace the upper ridge today and 
there will be a change to cooler and moister weather. Temperatures 
will cool to the seasonal normals by Wednesday. A series of weak 
fronts will result in periods of light rain this afternoon through 
Friday. A more organized front will move across the region this 
weekend. 
&& 


Short term...today through Friday...the upper ridge axis is 
currently over the Cascades allowing an upper trough over the NE 
Pacific to approach the coast. Marine clouds have filled in over the 
central Oregon coast and Coast Range early this morning...but the 
north Oregon and Washington coast are mostly clear. Satellite imagery 
shows low clouds ahead of an approaching cold front quickly 
approaching the Washington and north Oregon coast. This stratus will 
merge with the stratus already established along the central Oregon 
coast and fill in the entire coast by sunrise. The marine layer will 
deepen as the upper trough approaches this morning...allowing the 
marine clouds to push further inland...into parts of the Willamette 
Valley after sunrise. 


The cold front will weaken as it approaches the coast...but may hold 
together enough to generate some drizzle along the coast this 
morning...and some showers inland this afternoon. Cloudier skies and 
cooling aloft will result in much cooler temperatures this afternoon 
compared to the last few days...with high temperatures along the 
coast in the middle to upper 50s and inland temperatures in the low to 
middle 60s. 


A chance of showers will continue tonight into Wednesday as the upper 
trough swings over the area. Most of these showers will be limited to 
the higher terrain. Snow levels will lower to around 3000 feet by 
Wednesday morning...but the precipitation totals will be so light 
that there is not a concern for snow at the passes. The precipitation 
will decrease from south to north Wednesday afternoon and evening. 


Another weak cold front will approach Wednesday night and possibly 
bring some light rain and mountain snow to the region Thursday and 
Thursday night. A weak upper level trough will maintain showers 
Friday. Daytime temperatures will remain near normal...in the low 60s 
inland and in the 50s for the coast Thursday and Friday. Tj 


Long term...Friday night through Monday...models continue to 
struggle on the details...but suggest a wetter frontal storm system 
will slowly sag southward across the area late Saturday through 
Sunday night. As a result...probability of precipitation were increased in the likely to 
categorical range for the prime window of Saturday night and Sunday. 
Both models suggest another storm system is likely next week...but 
once again differ on timing so probability of precipitation were trended more into the high 
end chance to low end likely range. /Neuman 
&& 


Aviation...VFR inland while areas of IFR on the coast. A weak 
front will push another batch of stratus to the coast. This is 
expected to bring ceilings around 1500-2500 feet to the coast through 
at least this evening. Portions of the interior will probably see 
MVFR ceilings between about 15z and 20z Tuesday. However westerly onshore 
flow may retain occasional mountain obscuration through this 
evening. 


Kpdx and approaches...MVFR stratus around 2000 feet affecting the 
terminal 16z to 20z Tuesday. VFR returns by 20z Tuesday with northwest winds 
picking up middle afternoon into early evening. /Mh 
&& 


Marine...a weak front will bring a slight wind shift across the 
waters this morning. The main effect however will be increase in 
northwesterly winds into the Small Craft Advisory category which should 
last into Wednesday morning.A much stronger front looks to move 
across the waters over the weekend and will likely bring gusty 
southerly winds and another round of building seas. 


Seas will also increase with northwesterly swell exceeding 10 feet later this 
afternoon and peak around 10 to 12 feet tonight before subsiding 
below 10 feet Wednesday evening. This will lead to rough bar during the 
next few ebbs. Will have to watch the tonight period if seas rise 
a little higher than anticipated rough bar conditions may occur 
during non Ebb time. /Mh 
&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds from 7 am this morning to noon 
PDT Wednesday for waters from Cape Shoalwater Washington to Florence 
or from 10 to 60 nm. 


Small Craft Advisory for hazardous seas from 4 PM this 
afternoon to 6 PM PDT Wednesday for coastal waters from Cape 
Shoalwater Washington to Florence or out 60 nm. 


Small Craft Advisory for winds from 1 PM this afternoon to noon 
PDT Wednesday for coastal waters from Cape Shoalwater Washington to 
Florence or out 10 nm. 


Small Craft Advisory for rough Columbia River bar from 
6 am to 10 am PDT this morning. 


Small Craft Advisory for rough Columbia River bar from 
7 PM to 10 PM PDT this evening. 


Small Craft Advisory for rough Columbia River bar from
