NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
846 PM PDT Thursday Jul 31 2014 


Synopsis...an upper level ridge over The Rockies and Great Basin 
will remain into the weekend...before flattening out early next 
week. A series of weak shortwave troughs aloft will lift north through 
the Pacific northwest over the next few days bringing a chance for 
thunderstorms...mainly to the Cascades. 
&& 


Short term...shortwave located via water vapor imagery near the 
Oregon California border and moving slowly north is already 
supporting a couple of showers and thunderstorms ahead of it just 
offshore and over the Coast Range near Newport. Updated forecast to 
add shower and thunder chances along the coast and into the central 
Oregon Coast Range. Hrrr has been indicating some shower activity 
near the coast...but timing is much too late compared to current 
radar picture. Models suggest best instability overnight will be 
over the Cascades but could see some additional shower and 
thunderstorm activity over the central and north Willamette Valley 
as hinted at by a number of models including the NAM and hrrr. 
Previous discussion follows for the rest of the forecast period as 
no updates appeared necessary. /Bowen 


Models in general indicate the shortwave lifting NE 
of the region Friday morning so will include a slight chance for 
convection into Friday morning across the north. Additional weak shortwaves 
indicated in models to follow Sat and to a lesser extent sun...but 
with the middle and upper level flow becoming increasingly SW to 
westerly. Expect this to relegate the threat for thunderstorms more 
to the Cascades Friday afternoon...and limited more to the Oregon 
Cascades Sat and sun. 


The lack of any kind of marine push last night was likely related to 
the shortwave sitting off the S Oregon and north California coast. As the wave 
lifts north tonight and Friday though expect onshore flow to pick up 
a bit tonight suggesting more marine clouds on the coast...and an 
even better push Friday night suggesting the potential for some clouds 
pushing inland by Sat morning...as well as a few degrees of cooling 
by Sat. A similar situation Sat night into sun suggests again some 
marine clouds pushing inland for Sun morning...and high temperatures again 
a bit cooler sun but likely still above normal. 


Long term...models in pretty good agreement in showing the region 
under a weak 500 mb flow through most of next week...with a 
continuation of a modest low level onshore flow as a result of the 
high over the NE Pacific. Overall looks like a dry pattern with the 
flow aloft seeming to favor a light westerly wind...and temperatures 
remaining a bit above normal. 


&& 


Aviation...altocumulus clouds will continue to spread across the 
area this evening and into tonight...bringing a threat for elevated 
thunderstorms to work its way from south to north overnight. Suspect 
the Portland metropolitan taf sites stand the best chance of experiencing 
thunder from 06z-12z Friday. Conditions should otherwise remain VFR 
for interior taf sites through 00z Saturday. Coastal sites may see 
some vicinity MVFR fog develop overnight...but confidence remains 
low. /27 


Kpdx and approaches...high pressure and northwest flow will maintain VFR 
conditions through 00z Saturday. There is a 10 percent chance of a 
thunderstorm impacting the terminal between 06z-18z Friday. 
/Neuman 


&& 


Marine...only subtle day to day variations expected in the weather 
pattern through the weekend as high pressure remains over northeast 
Pacific. This will maintain a typical summertime pattern of 
northerly winds...generally increasing each afternoon through around 
midnight. Will keep small craft advisories going for the near shore 
waters...but decided to drop the central Oregon outer waters where 
models have been underachieving all day. 


High pressure sagging southward Friday and Saturday will likely keep 
Small Craft Advisory level wind gusts of 25 knots from materializing 
across all the waters even though model guidance suggests otherwise. 


Nonetheless...the general weather pattern will continue to produce 
locally generated wind waves/fresh swell....leading to choppy 
seas...but with total wave heights generally remaining 5 feet or less. 
/Neuman 


&& 


Pqr watches/warnings/advisories... 
or...WA... 
pz...Small Craft Advisory for winds until 11 PM PDT this evening 
for coastal waters from Cape Shoalwater to Florence out 10 
nm.
