Severe Weather Alert Descriptions

 Special Statement  Statement as of 9:43 am PDT on July 28, 2014


... Very warm weather this week in southwest Washington and
northwest Oregon...

A very warm week is on tap across the interior of southwest
Washington and northwest Oregon. The warmest temperatures will be
in the inland valleys such as the Willamette Valley... the
Columbia River gorge... the Interstate 5 corridor in southwest
Washington... and the Upper Hood River Valley... where values from
90 to 95 are possible through Tuesday... with upper 80s to near 90
later in the week. The Coast Range and the Cascade foothill
temperatures will close to those values as well.

Maintaining proper hydration will be very important for any
outdoor activities planned this week. Avoid extra exertion during
the afternoon and early evening hours. Do not leave children or
pets unattended in cars... as this can be fatal. Many fatalities
that have occurred over the years during hot spell episodes have
taken place on area rivers... including several that occurred
during our last hot spell earlier in July. Take extra care while
engaged in recreation on area rivers this week.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
246 PM PDT Tuesday Jul 29 2014 


Synopsis...an upper level ridge remains anchored over the Great 
Basin and northern rockies. Upper level low pressure lingers off the 
West Coast of Canada...as a result the Pacific northwest remains 
under south to southwesterly flow aloft. The result is very weak 
onshore flow...enough to affect the immediate coastal valleys while 
the interior remains very warm. Weak disturbances lifting north from 
California will bring a chance for thunderstorms at times to the 
Cascades...especially Lane County. Little change expected in this 
overall pattern the next several days. 


&& 


Short term...today through Thursday night...thunderstorms have 
developed along the Cascade crest this afternoon...with one 
particularly large cell which was warned on near McKenzie Pass. 
Radar hail size estimates maxed out at 1.75 inches...approaching 
ping pong Ball size...though actual hail size was likely a bit lower 
than that. 0-6 km bulk shear really not all that impressive...so 
this storm appears to have fed a bit off of converging upslope winds 
along the Cascade crest as it drifted northward. Perhaps one or two 
more strong cells could develop similarly this afternoon...but we 
are not anticipating this to be a widespread occurrence. 


Another driver for the thunderstorm development this afternoon was a 
weak disturbance and jet maximum pushing into the Oregon Cascades from 
the southwest. This also may have helped push the above mentioned 
cell to severe limits. As the jet maximum moves on and the sun GOES down 
expect any thunderstorm activity to decrease rapidly this evening. 


For most of the forecast area...the main story is and will continue 
to be the very warm to hot weather inland. Temperatures are approaching or 
have already surpassed 90 degrees at many inland locations as of 2 
PM. While temperatures have cooled off nicely into the 50s in the outlying 
valleys...urban areas and exposed hillsides have seen less relief 
with temperatures only bottoming out in the 60s. There will be little change 
in this over the next few days as an upper level ridge only gradually 
weakens over the Great Basin and northern rockies. Coastal areas will 
remain cooler as a weak onshore component to the flow continues. 


Risk for thunder decreases temporarily Wednesday as most models 
depict weak shortwave ridging transits the region. Still cannot 
totally rule out thunder on the crest as lapse rates remain decent. 
Moisture appears less abundant though...and again there should be 
subsidence from the shortwave ridging. Chances increase again Thursday/Thursday 
night as the remnant moisture of Post-tropical cyclone Hernan lift 
north and possibly combine with one of the weak shortwaves presently 
off the California coast beyond 130w. For now...most models suggest 
this energy and moisture are targeting areas along the Cascade crest 
and points east. However it is not out of the question areas further 
west could be affected if the shortwave becomes strong enough to pull 
in some southeast flow aloft. For now...just increased probability of precipitation a bit along the 
crest of the Oregon Cascades Thursday/Thursday night. Weagle 


Long term...Friday through Tuesday. Our area is on the west side of 
an upper-level ridge over the western Continental U.S.. several shortwaves are 
forecast to move up this ridge and bring chances for thunderstorms 
along the Cascade crest. This ridge will remain stationary through 
Tuesday. Uncertainty remains for timing and location of 
thunderstorms...but looks like best chance will stay along the 
Cascade crest.The stationary nature of this weather pattern will 
keep high and low temperatures fairly persistent until this upper- 
level ridge either breaks down or moves off to the east. -McCoy 


&& 


Aviation...stratus and fog will continue to hug the coastline 
with IFR conditions expected tonight into Wednesday morning. VFR 
conditions for the inland airports tonight. A few isolated 
thunderstorms possible along the Cascade crest this 
evening...mainly south of Montana Jefferson. Some debris clouds 
possible over the Cascades drifting north-northeast. 


Kpdx and approaches...VFR prevailing tonight and Wednesday with 
generally light north-northwest surface winds. 


&& 


Marine...surface high pressure will remain over the NE Pacific 
as a thermal trough holds over northern California. The thermal 
trough will rise slightly north in the afternoon and evenings 
resulting in a tighter pressure gradient over the Oregon waters. 
Gusty winds can be expected at these times...occasionally reaching 
or exceeding 25 knots. The gradient will be tightest south of 
Tillamook. 


The seas will primarily be driven by the local winds. Steep seas 3 
to 5 feet will dominate through the week. There are some 
background longer period seas that may occasionally show up on 
the buoys...but these are very small...1 foot or less...and less 
significant to the mariner than the 3 to 5 feet seas at 6 to 8 
seconds. The steep seas will be a combination of wind wave and 
fresh swell which is nearly impossible to distinguish and have 
therefore combined the seas in the forecast. The seas will be the 
steepest when the winds are the greatest...during the afternoons 
and evening...and especially south of Cascade Head and near shore.

Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 11 PM PDT this evening for 
coastal waters from Cape Shoalwater Washington to Cascade Head or 
out 10 nm-coastal waters from Cascade Head or to Florence or
