NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
236 PM PDT Monday Apr 20 2015 


Synopsis...increasing onshore flow will lead to near average 
temperatures and an increase in marine clouds Tuesday through Friday. 
There will be a small chance of a shower each day during this 
period...particularly along the coast and Cascades...but most 
locations will generally remain dry. A wetter pattern looks to 
develop late Saturday and Sunday...with perhaps another round of wet 
weather early next week. 


&& 


Short term...visible satellite imagery reveals mainly clear skies 
across the area except for some low clouds skirting the coastline 
under low level northerly flow. Surface low pressure is shifting 
inland this afternoon...which will result in low clouds pushing into 
the Coast Range gaps this evening...and perhaps a brief surge of 
westerly winds. Low clouds should spread into the Willamette Valley 
overnight and Tuesday morning...but due to the shallow nature of the 
this marine push...the current cloud cover forecast in the Willamette 
Valley may be a bit too pessimistic...especially across the southern 
and western portions of the valley. 


Temperatures on Tuesday should top out approximately 10f cooler than 
today due to the much stronger marine influence expected in the 
Willamette Valley. Onshore pressure gradients look to increase 
further Tuesday afternoon and evening so expect breezy conditions to 
develop...especially near the Coast Range gaps and central Columbia 
River gorge in the late afternoon and evening hours. 


Shallow instability and moisture may produce a few very light showers 
Tuesday night into early Wednesday...particularly across the north 
and in the upslope areas...but confidence is low. A weakening front 
may bring increasing light rain chances to our far northwest zones 
on Thursday. All in all...most locations look to remain generally 
dry the next few days with temperatures topping out near average. 
/Neuman 


Long term...Thursday night through Monday...models continue to 
struggle on the details...but suggest onshore flow will continue near 
average temperatures with a chance for some light showers Thursday 
night and Friday. While models differ on timing...but the GFS and ec 
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...mostly VFR under hazy skies through this evening. The 
flow pattern will continue to turn onshore this afternoon as a 
weak front approaches the region allowing marine stratus to fill 
back in along the coast between 00z and 03z. Expect IFR ceilings 
between 500 and 1000 feet and reduced visibility along the coast through 
late Tuesday morning. Clouds continue to push inland tonight...with 
interior site likely seeing MVFR ceilings between 1500 and 2000 feet by 
15z. Conditions turn VFR under mostly cloudy skies Tuesday afternoon. 


Kpdx and approaches...VFR under hazy skies through this evening. 
Lower clouds return tonight...with MVFR stratus affecting the 
terminal by 14z. 


&& 


Marine...a weak front will move across the waters tomorrow 
morning bringing gusty northwesterly winds and building seas. 
Expect gusts to 35 knots and seas around 11 feet from Tuesday morning to 
Wednesday. High pressure briefly returns Wednesday afternoon before another weak 
front moves across the waters on Thursday. Not expecting much in the 
way of impacts with this second front. 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. 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds from 7 am Tuesday 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 Tuesday to 6 
PM PDT Wednesday for coastal waters from Cape Shoalwater Washington to 
Florence or out 60 nm.

Wednesday for coastal waters from Cape Shoalwater Washington to
