NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
250 PM PDT Wednesday Jul 30 2014 


Synopsis...an upper level ridge over The Rockies and Great Basin 
remains our most dominant weather feature...keeping temperatures a 
few degrees above normal inland. This ridge will slowly erode over 
the next several days...eventually allowing more onshore flow and 
slightly cooler temperatures by early next week. In the mean time 
south-southwesterly flow aloft continues to guide weak disturbances 
into our area for occasional thunderstorm chances in the Cascades. 
One such disturbance should promote another day of enhanced Cascade 
thunderstorm activity Thursday...with another possible Saturday. 


&& 


Short term...tonight through Saturday...more or less a persistence 
pattern this week over the forecast area...with only small variances 
from day to day. The large weather picture continues to include an 
expansive upper level ridge over The Four Corners...Great Basin... 
and northern rockies. Meanwhile an upper level low persists in the 
Gulf of Alaska. These two features have been causing the upper level 
flow to vary from southwesterly to southerly at times...depending on 
weak disturbances riding along the southeast periphery of the Gulf of 
Alaska upper low. The proximity of the upper ridge has kept the 
marine layer shallow...with all but immediate coastal areas warming 
up a few degrees above normal each day. 


The Pacific northwest is presently between upper disturbances... with 
weak shortwave ridging transiting the region. The associated 
subsidence and slightly warmer temperatures aloft are likely why 
convection has been limited this afternoon...even in the Cascades. 
Thursday should be a different story...as a well defined vortmax is 
gaining strength off the California coast near 35n/135w. Meanwhile remnant 
moisture from excessive-Hurricane Hernan is lifting north into California. 
These two features should combine for fairly widespread convection 
for the Cascades east Thursday and Friday...starting in northern California 
then lifting through Oregon Thursday...then into Washington Friday. 


Pattern recognition-wise it appears likely at least a couple 
thunderstorms will form in our Cascades zones Thursday. However 
looking at model soundings...both moisture and instability are rather 
marginal. That said...modifying NAM or GFS bufr soundings to reflect 
the forecasted temperatures in the Cascade crest yields quite a bit of 
surface based instability...up to 1000 j/kg of cape or more. Overall 
chance of thunderstorms appears to be the best forecast south of Montana 
Jefferson...with a slight chance extending into the foothills of Lane 
County. Slight chance of thunder extends north into the Washington Cascades 
Friday. With flow aloft mainly S-SW...it appears unlikely thunder will 
drift west of the Cascades. A baggy upper level trough lingers over 
the Pacific northwest into the weekend as the upper ridge erodes to our east. 
This could provide enough instability for isolated to scattered 
Cascade thunderstorms to continue into Saturday. 


Elsewhere...expect little sensible change the next few days. High 
temperatures will remain somewhere near 90 degrees for the inland valleys 
while coastal areas are seasonably cooler with highs in the 60s and 
lower 70s. Slightly drier northerly flow temporarily cleared the 
stratus from the coastal waters today...but suspect it will come back 
behind the disturbance Thursday night. No significant deepening nor inland 
intrusion of the marine layer is expected through this weekend. 
Weagle 


Long term...Saturday night through Wednesday...fairly good consensus 
between the medium range models that the upper ridge to our east will 
gradually erode through early next week. This may allow a greater 
westerly/onshore component to the flow...perhaps cooling inland areas 
by a few degrees and down closer to normal. As onshore flow becomes a 
bit stronger...expect the thunder risk to decrease on our side of the 
Cascades. Also the marine layer should deepen a little...pushing a 
bit further inland as the thermal low over the middle-Columbia becomes 
more dominant and increases the onshore pressure gradient/flow. No 
significant widespread rain events on the horizon going well into 
next week. Weagle 


&& 


Aviation...high pressure and weak onshore flow will generally 
keep conditions VFR through 00z Friday. Patchy IFR conditions 
will likely develop along the coast towards 09z to 12z 
Thursday...but not confident widespread IFR conditions will 
develop up and down the coast. 


Kpdx and approaches...high pressure and northwesterly flow will 
produce VFR conditions through 00z Friday. There is a 20 percent 
chance high end IFR conditions will impact the terminal between 
12z and 15z Thursday. /Neuman 


&& 


Marine...little change to the overall pattern through the 
upcoming weekend as high pressure lingers over the northeast 
Pacific and thermal low pressure remains over northern California. 
This will produce a fairly typical summertime pattern of gusty 
northerly winds at times. The gustiest winds will be primarily 
centered over the central Oregon waters for the next couple of 
days...before the ridge axis shifts slightly more southward...and 
perhaps keeps small craft winds from materializing across all of 
our waters towards the weekend...despite model guidance suggesting 
otherwise. 


Continued the combined seas wording in the coastal waters forecast 
due to the waves being primarily a mixture of wind wave and fresh 
swell. In general...expect seas to be choppy with heights 
fluctuating between 4 and 6 feet through the weekend. /Neuman 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 11 PM PDT this evening for 
coastal waters from Cape Shoalwater Washington to Cascade Head or 
out 10 nm-coastal waters from Cascade Head or to Florence or 
out 60 nm.
