 Heat Advisory  Statement as of 6:38 am PDT on July 5, 2015


... Heat advisory remains in effect until midnight PDT Wednesday
night for most inland valleys and Cascade foothills of southwest
Washington and northwest Oregon... including the greater Portland
and Vancouver Metro area...

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

* High temperatures: generally in the 90s... except 85 to 95 in
the higher terrain and lower Columbia. Hottest time of the day
will be 1 PM to 6 PM each afternoon.

* Low temperatures: temperatures will continue to be slow to
cool off in the evening... especially in urban areas and
higher terrain. Lows will generally be in the upper 50s and
60s.

* Relief: not likely until a significant pattern change occurs
later this week.

* Locations include: Vancouver... Battle Ground... Washougal...
ODell... Sandy... Estacada... Sweet Home... Salem...

can heat up rapidly to temperatures harmful or even deadly
to pets and children. Use caution near area rivers... be
water smart... wear a life jacket and use good judgment.

Precautionary/preparedness actions...

Take extra precautions if you work or spend time outside. When
possible... reschedule strenuous activities to early morning. Know
the signs and symptoms of heat exhaustion and heat stroke. Wear
light weight and loose fitting clothing when possible and drink
plenty of water.

To reduce risk during outdoor work the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency... call 9 1 1.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
321 am PDT sun Jul 5 2015 


Synopsis...the heat is on across inland southwest Washington and 
northwest Oregon...and will remain on through midweek. A stagnant 
pattern remains in place across the region with a ridge of high 
pressure aloft remaining dominant. A brief cooldown is possible 
tonight and Monday for Eugene as a southwest surge of marine air 
pushes through the adjacent Coast Range. Otherwise onshore flow will 
be weak and ineffective at bringing much relief from the heat inland 
through Wednesday. An upper low off California may drift far enough 
north Tuesday/Wednesday to bring thunderstorms up the Cascade crest to Lane 
County by midweek. 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 Tuesday...the prolonged heat wave of 2015 
continues across SW Washington and northwest Oregon...with little change in 
the overall weather pattern which has rendered onshore flow weak and 
ineffective for all but the immediate coast. Upper level ridge axis 
remains stretched from Texas/Four Corners region through Oregon and 
into the NE Pacific. The upper ridge continues to compress the marine 
layer such that onshore flow is robbed of its cooling influence by 
the time it reaches more than a few miles inland. 


Onshore pressure gradients are weakening this morning as a clipper 
system moving through British Columbia and Alberta turns the flow 
more northerly across Washington/north or. High pressure building behind the 
associated cold front will likely push thermal low pressure offshore 
today...further limiting onshore flow or even turning it a little 
offshore across western Washington. With any vestige of a marine inversion 
eliminated...temperatures will likely heat up a few degrees today versus 
Saturday despite similar 850 mb temperatures in the +20 to +21 degree c range. 
This will bring high temperatures close to 100 today for many inland valley 
locations...including the pdx metropolitan and Salem. 


With thermal low pressure being shoved off the Washington coast and weak flow 
aloft...an ideal setup will be in place for the development of a 
southerly surge of marine air to develop and push up the coast 
tonight. Depending on how deep this push of marine air can get...it 
has the potential to bring some decent cooling to the central Coast 
Range and even the Eugene metropolitan. Decided to end the heat advisory for 
these zones this evening...as 4 km WRF-arw and NAM guidance suggest 
cooling SW winds pushing into the S Willamette Valley tonight. Some 
models are so bullish with this marine push that they even bring some 
low clouds into the Eugene area Monday morning...suspect this is a 
little overdone. 


Areas further north are a different story...as it is doubtful the 
marine push will be strong enough to affect areas Salem northward. 
With little change in air mass...and onshore flow mitigated due to 
low pressure/weakened high pressure offshore...expect a few more hot days 
with highs reaching well into the 90s through Wednesday. A weak flow 
pattern will keep nights warm. GFS/European model (ecmwf) ensemble guidance show 
excellent agreement that little change is likely through Wednesday...so we 
decided to extend the heat advisory through Wednesday evening. Hopefully 
this will be as far as we need to go with it...as models show good 
agreement on our upper ridge breaking down/shifting east by late 
week. 


Meanwhile...upper level low pressure will be nearly stationary off 
the California coast. Models suggest it will remain too far south to 
spread enough moisture/instability far enough north to induce a 
thunderstorm threat for the Lane Colorado Cascades. Some debris cloudiness 
is possible from time to time due to convection to our south...but it 
appears thunderstorms are unlikely until at least Tuesday/Wednesday unless the upper 
low wobbles further north than currently expected. Weagle 


Long term...no changes. Previous discussion follows... 
Tuesday night through Saturday...Rex block remains in place through 
middle-week with continued hot and dry weather across the area. Models 
continue to suggest Rex block over the West Coast starts to break 
down later this week as an upper-level trough pushes the ridge of 
high pressure off to the east. There is still some disagreement on 
when this will actually break down...but ensembles suggest a good 
chance that the blocking pattern breaks down by Friday. This should 
bring temperatures down some for Friday and Saturday with a chance 
for some cloud cover as well. There is a slight chance for a 
thunderstorm or two later this week in the Lane County Cascades as 
the upper-level trough moves through...but elsewhere looks to remain 
dry into next weekend. -McCoy 


&& 


Aviation...IFR stratus and fog developed along the immediate 
coast. Ceilings are generally under 800 feet with some locations in fog 
with visible less than 1/2 mile. The stratus and fog should clear by 
17z Sunday. A southerly wind reversal will develop along the 
coast from south to north during the day today. This will bring 
stratus will return to the coast by late afternoon on the central 
coast and tonight for the South Washington coast. VFR conditions 
prevail inland through early Monday. 


Kpdx and approaches...VFR will continue through early Monday. /26 


&& 


Marine...the pressure gradient will continue to weaken over the 
waters today as a thermally induced low moves offshore. The 
thermal low will expand off of the Oregon coast today resulting 
in a southerly wind reversal. Southerly winds will develop first 
for the central Oregon coast in the afternoon...then for the 
Washington coast tonight. A weak pressure gradient will continue 
through at least Wednesday keeping surface winds light...less than 
15 knots. The thermal low will weaken by Thursday with west-northwest winds 
returning. 


Seas will gradually subside today and remain below 6 feet through 
Thursday. The very strong morning Ebb will likely result in rough 
bar conditions so a Small Craft Advisory will be issued. /26
