NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
315 am PDT Sat Sep 20 2014 


Synopsis...thermal low pressure over SW Oregon coast will build 
north along the Pacific northwest coast today...as high pressure remains inland. 
Easterly winds will keep skies sunny and support temperatures in the 
80s for the coast and possibly low 90s for inland areas today. Cooler 
onshore flow will return Sunday.Monday will be mostly cloudy as a 
weak front brushes by. A stronger front will likely bring widespread 
rain Wednesday. 


&& 


Short term...today through Monday night...satellite imagery shows a 
sliver of low marine clouds along the immediate coast early this 
morning. The skies are otherwise clear...except marine stratus is 
starting to push up the lower Columbia River. Light northerly winds 
this morning will be replaced by easterly winds late this morning as 
a thermal trough pushes off the coast. The easterly winds will be 
gusty through the Columbia River gorge and Cascade gaps...and will 
support a sunny and warm day. Temperatures will likely peak in the 
low 90s for the Interior Valley and middle to upper 80s for the coast. 


East winds and low relative humidities will produce conditions 
favorable for wildfire growth...and smoke from the 36-pit and 
deception fires should spread back into the Willamette 
Valley today. 


The thermal trough will weaken this evening and southerly winds will 
develop along the coast. Low marine clouds currently over northern 
California will surge northward and reach Newport tonight. The low 
clouds will continue to slide northward along the coast and reach 
Astoria shortly after sunrise Sunday morning. This will result in 
drastic cooling for the Oregon coast. Onshore winds Sunday afternoon 
will bring the cooler marine air inland and temperatures should peak 
in the middle 80s for the interior valleys and the 60s for the coast 


An upper level trough will approach Sunday night and the marine 
stratus will push further inland Monday morning. A weak surface front 
will maintain cloudy skies...at least to northern areas...through 
Monday afternoon. Do not expect much if any rain from this 
front...just a few sprinkles here and there Monday night. Tj 


Long term...a stronger cold front will approach Tuesday and bring 
widespread rain to the region Wednesday. Models show precipitable 
water approaching 1.5 inches with this front...and a 120kt 500mb jet 
to provide lift. This may result in some areas measuring an inch or 
more of rain. A couple of wet disturbances wrapping around the main 
upper low in the Gulf of Alaska will maintain cool and showery 
weather through the end of the week...and possibly into the weekend. 
Tj 


&& 


Aviation...generally VFR conditions will continue over northwest Oregon 
as offshore flow increases today and eases tonight. There will be 
some patchy fog and low clouds along the coast through 16z. 


Kpdx and approaches...VFR conditions will continue through 06z 
sun. East winds increase in the area later this morning through 
the afternoon...then ease tonight. East wind probably surfacing at 
kpdx around 18z and peaking 21z Sat through 00z sun. 


&& 


Marine...marginal Small Craft Advisory northerly winds over the 
central coast this morning with a lesser chance to see small craft 
winds further north. Winds should ease in the afternoon as the thermal 
trough expands over the waters...easing the pressure gradients. 
Tonight a weak low pressure center will move up offshore...turning 
winds to the S. Gusts likely to approach 20 knots sun. Shallow 
stratus and fog usually come with the wind reversal. 


A westerly swell 8 to 9 feet arrived in the northern zones and 
should fill in the southern zones this morning. Seas then slowly 
subside over the next few days. 


A more active pattern will arrive middle week with small craft or 
higher winds and seas building to over 10 feet. 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 11 am PDT this morning for 
coastal waters from Cascade Head or to Florence or out 60 nm. 


Small Craft Advisory for rough Columbia River bar from noon 
today to 4 PM PDT this afternoon.
