NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
910 am PDT Friday Jul 31 2015 


Synopsis...strong upper level high pressure will keep very hot 
weather in place today. Upper level high pressure will move east of 
the region and allow temperatures to gradually cool through the 
middle of next week. Monsoonal moisture from the south will bring a 
slight chance of a shower or thunderstorm to the Oregon Cascade 
crest late in the weekend and early next week...but confidence 
remains low. 


&& 


Short term...today through Monday...another hot day expected across 
the region. The exception is the coast where light onshore flow is 
bringing cooler marine air to the coastal strip. Inland temperatures will 
once again reach into the century mark...but expected to top a 
couple of degrees below yesterday/S readings. Mostly notable cooling 
will be in the lower Columbia near Kelso. Least amount of cooling 
will be in the south and Central Valley where temperatures will once again 
be over 100 degrees. 


Satellite imagery this morning shows some low clouds along the north 
coast. There is also a little smoke in the far southern that is 
moving northward from the fire in SW Oregon. Elsewhere...mostly 
sunny across the region. 


The upper level ridge axis will shift east of the region over the 
weekend resulting in middle level southerly flow which will bring an 
increase in middle to upper level clouds. Model soundings show some of 
the initial moisture will likely be too high to produce elevated 
thunderstorms on Saturday...but this may begin to change towards 
Saturday night or Sunday across eastern Lane and Linn counties. 
Confidence remains low though...as models do not really show much in 
the way of a middle level trigger. 


Meanwhile...between the increase in middle and upper level clouds 
spreading northward and strengthening low level onshore flow through 
early next week...expect high temperatures to trend downward several 
degrees each day through early next week. Unfortunately...not sure 
there will be one day where we can say it is going to feel 
noticeably better than the day before...but the good news is that by 
the time early next week roles around...it will be noticeably cooler 
than the triple digit heat of yesterday and today. Tw/neuman 


&& 




Long term...no changes. Previous discussion follows...Monday night 
through Friday...an upper level trough will gradually approach the 
region from the northwest. Confidence is relatively high that more 
seasonal average temperatures and periods of morning clouds and 
afternoon sunshine will return towards the middle of the week. 
Models continue to waver on thunderstorm chances near the Cascade 
crest early next week. Generally kept the slight chance mention 
going given uncertainty. In addition...models suggest showers may 
spread into at least far northwest Oregon and southwest Washington 
later in the week. Confidence remains low in this scenario...but 
introduced slight chance probability of precipitation across our northwest zones as a 
result. /Neuman 




&& 




Aviation...inland VFR will prevail although there will be areas 
of smoke mainly above fl080 near and along the Cascades. Hazy 
conditions along the coast with stratus likely to break up near kast 
over the next couple hours. Also expect gusts mainly 20 to 25 knots 
there with localized 25 to 30 knots closer to Florence. Not sure 
about coastal conditions tonight as model guidance indicates very 
dry conditions remain...but may go for a persistence forecast as 
a first thought. 


Kpdx and approaches...VFR conditions today and tonight. 


&& 


Marine...no changes...previous discussion follows. High pressure 
lingering over the offshore waters through sun will keep north winds 
blowing over the coastal waters through the weekend. Expect the 
winds to pick up some later today as the trough of low pressure over 
western Oregon moves further inland...resulting in wind gusts 
rising into the 20 to 25 knots range from late today into sun. Seas 
will remain dominated by north to northwest wind waves and fresh 
swell...keeping seas steep and at times necessitating an advisory 
for hazardous seas mainly during late afternoon to overnight 
hours. 


The high pressure weakens by late sun and Monday...allowing a weak cold 
front to move S into the waters late Monday. System looks weak enough 
to allow winds and seas to drop below small craft criteria.
