Willamette Valley... the western and central Columbia Gorge... the
Hood River Valley... and the north Oregon Cascade foothills...

A heat advisory remains in effect until midnight PDT Wednesday
night.

the signs and symptoms of heat exhaustion and heat stroke. Wear
light weight and loose fitting clothing when possible and drink
plenty of water.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
348 am PDT Monday Jul 6 2015 


Synopsis...hot weather will continue over most of the region through 
midweek as a strong ridge of high pressure aloft remains over the 
area. The exception is the coastal region...where cooler marine air 
will hug the coastline the next several days. An upper low off 
California may drift far enough north this week to bring 
thunderstorms up the Cascade crest in Lane County. Relief from 
the heat may come later this week as the upper ridge breaks down 
enough to allow stronger onshore flow. 


&& 


Short term...today through Wednesday...weather maps this morning 
look awfully similar to how they have looked the past several 
days...with SW Washington and northwest Oregon remaining locked in a hot and 
stagnant weather pattern. A col pattern established itself over the 
region late last week...with a cutoff low off the California coast...upper 
troughs clipping western Canada...and upper level highs over the 
Great Basin and NE Pacific. This type of pattern tends to lock itself 
in for a while and this has been no exception. 500 mb heights remain 
well above normal across the region...even within the upper trough 
over southern British Columbia/NE Washington. 


That said...a decent southerly wind reversal pushed up the coast 
Sunday...deepening the marine layer with stratus tops 1500-2000 feet 
this morning. If memory serves ME correct...this is deeper than the 
marine layer has been in a couple weeks. The stratus is pushing well 
into the coastal valleys this morning...with a ceiling already in 
Kelso. This is probably an indication that enough cooling will occur 
with the onshore flow this afternoon to keep Kelso below 90 degrees. 
Therefore we will be canceling the heat advisory for the lower 
Columbia...I-5 corridor in Cowlitz County...and S Washington Cascade 
foothills. 


With 500 mb heights remaining in the mid-580s...the marine layer will 
probably be too shallow to have much of an impact on areas further 
inland today/Tue...and a shortwave passing to the north may weaken 
onshore gradients Wednesday. 850 mb temperatures remain near +20 degree c through 
Wednesday. Therefore will leave the heat advisory in effect for these areas 
as valley highs are still expected to be in the 90s through Wednesday. If 
this occurs at pdx...it would tie the longest stretch of 90+ degree 
days on record...Jul 25-Aug 3 2009. 


One caveat is the south Willamette Valley...where the heat advisory 
looks borderline due to a prolific west-SW push of marine air... 
continuing this morning with 10-20 miles per hour winds at cvo and eug. Would 
not be surprised to see high temperatures stick near or even below 90 
today...but will leave the heat advisory up as the air mass remains 
warm enough for low-middle 90s should the onshore flow shut off. 


The other thing to watch for the next few days is the potential for 
thunder in the Oregon Cascades. Models are a little more bullish 
about the potential for thunder this afternoon all the way up the 
Oregon Cascades to near Montana Hood. This seems a little overdone as the 
air mass aloft remains rather warm and model soundings seem to be 
exaggerating surface-based cape as usual with surface dewpoints that are 
probably too high. Also there is no obvious synoptic trigger on 
latest GFS/ec guidance. Models have been a bit too far north with 
thunderstorm coverage the past couple days...so holding with the current forecast 
of slight chance afternoon/evening thunder in the Lane Cascades the next few 
days looks reasonable.Weagle 


Long term...Thursday through Sunday...finally an end is in sight to 
this historic heat wave...as the blocking pattern which has kept US 
under anomalously high 500 mb heights breaks down. The high 500 mb 
heights have kept the marine layer shallow...robbing onshore flow of 
its cooling influence before it reaches the inland valleys. The most 
important change expected during the extended forecast period will 
likely be the slow lowering of overall 500 mb heights over the 
western United States and the NE Pacific...as the California Cutoff low opens 
up midweek and the mean upper ridge position slowly shifts eastward 
into the Great Plains. As overall heights lower...expect the marine 
layer to become deeper...thus becoming more effective in cooling the 
interior given onshore flow. 


Thermal low pressure will likely linger over the Willamette Valley 
Thursday...allowing one more fairly hot day...though the overall air 
mass will be cooling as 500 mb heights lower. Thursday night appears to be 
the big cooldown as the thermal trough moves into eastern Washington and 
encourages a strong SW push of marine air to push into the district. 
This will at least push temperatures closer to normal with night and 
morning low clouds extending inland by the weekend...however models 
diverge on whether or not an incoming upper trough can remain strong 
enough to produce showers. Decided to keep probability of precipitation very low...as models 
have a tendency to be too aggressive in pushing these Pacific systems 
onshore after being under a strong upper ridge. A more favored 
solution for the weekend is the 00z European model (ecmwf) solution...which leaves the 
upper trough axis offshore and southerly flow over the forecast area 
keeping temperatures close to normal rather than going below normal. 
Therefore we continue to be on the conservative side of guidance in 
the magnitude of cooling expected with this pattern change. Weagle 


&& 


Aviation...IFR stratus over the coastal waters all the way into 
the western slopes of the Coast Range and the lower Columbia River to 
kkls. The stratus should burn back to the beaches today...then 
return to the coastal areas late this afternoon. This means konp may 
remain under the stratus or only briefly break out later this 
morning. Inland areas will be VFR. Scattered to broken middle and high 
clouds will move over Lane County through today. 


Kpdx and approaches...VFR will continue through Monday night. Ceilings 
around 1300 feet at kkls as of 09z Monday may extend to near kspb 
but do not expect it to reach taf sites. /Mh 


&& 


Marine...surface trough west of the coastal waters and a surface 
ridge near the coast will continue today through Tuesday. Winds will 
be southerly today and generally less than 15 knots. The thermal 
trough will weaken tonight for light and variable winds through 
Tuesday morning. The surface trough will dissipate Tuesday night and 
Wednesday and high pressure over the NE Pacific will shift back over the 
waters...returning seasonal northwest winds. 


Seas subsided to around 5 feet...and will continue to subside 
another foot or so today. Seas should remain 5 feet or lower for 
much next week. /Mh
