NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
318 am PDT Friday Aug 1 2014 


Synopsis...an upper level ridge centered over The Rockies and Great 
Basin will remain into the weekend...before flattening out early 
next week. An upper level short wave moving very slowly through the 
Pacific northwest on the west side of the upper ridge will bring 
some thunderstorms to southwest Washington and northwest Oregon this 
morning. Additional weak disturbances will keep a chance of mainly 
afternoon and evening thunderstorms to mainly the Cascades through 
the weekend and into early next week. Temperatures will remain above 
normal...slowly approaching normal later next week at the earliest. 
&& 


Short term...an upper level short wave that the models have been 
advertising would slowly lift north through northwest Oregon and 
southwest Washington overnight and early this morning was producing 
elevated nocturnal thunderstorms from the east slopes of the Coast 
Range into the Cascades and on into central Oregon. The models 
indicated precipitable water values with this feature just over an 
inch. While rainfall amounts had been rather light much of the 
night...we are now seeing more measurable rainfall amounts hitting 
rain gages. Several gages have seen several hundredths of an inch... 
and expect a few places may have had one or two tenths. The back or 
southern edge to the associated infrared cloud mass is slowly moving 
north and should clear our southwest Washington zones later this 
morning. Until then...there will be isolated to scattered showers 
and thunderstorms moving north across our forecast area. 


There is little in the way of any fog or low clouds along the 
coast...so far it is mainly near North Bend. We may see a narrow 
ribbon form along at least parts of the coast this morning hut it 
may not be very solid. 


There is still some weak vorticity aloft over our area this 
afternoon...so expect a few more thunderstorms to develop again over 
the Cascades and foothills this afternoon and evening. Based on the 
position of the short wave...will also include a slight chance of 
thunderstorms back west toward the Willapa Hills and the north Oregon 
Coast Range...and include an adjacent piece of the Portland and 
Vancouver area as well. 


The models show the marine layer increasing along the coast tonight 
in the wake of this disturbance...with some low clouds moving inland 
along the Columbia River toward Portland by Saturday morning. The 
main short wave from today is well north of our area on Saturday... 
but some weak trailing energy should again give a chance of afternoon 
and evening thunderstorms over the Cascades Saturday. 


There is not a lot of change on Sunday...with a chance of 
thunderstorms over the Cascades again in the afternoon and evening. 
The inland push of low clouds into the coastal gaps looks better by 
Sunday...and expect a decent area of around Portland and Vancouver 
toward the Cascade foothills will have low clouds for several hours 
Sunday morning. After several days around 90...if this occurs it 
should drop the temperatures in the Portland and Vancouver area down to at 
least the middle 80s. Tolleson 


Long term...no changes. Previous discussion follows...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...isolated thunderstorms continue to push north through the 
Willamette Valley with frequent lightning observed. Expect thunderstorms in the vicinity to be 
carried through 18z across the Portland metropolitan taf sites...but 
probably ending by 12z-14z further south closer to keug. May see 
temporary visibility reduction to MVFR if a heavier thunderstorms and rain moves over a 
terminal...but otherwise VFR flight conditions. Storm threat should 
end across the valley by middle morning from south to north. Along the 
coast...may see some scattered low clouds start to develop but should 
remain VFR today at the coast through this afternoon...before some 
MVFR/IFR stratus may push onshore after 00z Sat. 


Kpdx and approaches...some thunderstorms continue to move from S to north 
towards the terminal. Expect thunderstorms in the vicinity through around 18z...with best 
chances for thunderstorms and rain at terminal between 10z-17z. These storms have 
produced abundant lightning overnight so this could impact terminal 
operations through around 17z. Thunderstorm chances may persist for 
another hour or two over eastern approaches. Cullen 
&& 


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. 


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...though would not be surprised to see occasional gusts to 
20-25 knots over the near shore waters today. 


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 
through early next week. Cullen
