Area Forecast Discussion
National Weather Service Spokane WA
451 PM PDT MON AUG 3 2015
.SYNOPSIS....
The ongoing drought, combined with high heat and low humidity
will contribute to high fire danger throughout the Inland
Northwest. Cooler temperatures and windy conditions are
expected...especially Tuesday and Wednesday following the arrival
of a cold front. Another threat of showers and thunderstorms
arrives next weekend.
&&
.DISCUSSION...
Tonight through Tuesday: No significant changes to the fcst.
Winds will continue to strengthen into early evening as pressure
gradients strengthen...most notably near the Cascades (Wenatchee
region) and parts of the Palouse. Otherwise...a weak short- wave
trough over Oregon will move NE and keep the threat of very light
showers in the fcst for all areas outside of the Columbia Basin.
Pcpn amnts should be no more than a trace for most towns due to
unimpressive instability and a very dry sub-cloud layer below
10-15k ft. Once this wave exits tonight, a cold front will move
across the region and produce very gusty, but dry conditions
Tues.bz
Tuesday Night through Friday Morning: A Low pressure system will
begin continue to push into the region and shift the ridge of high
pressure further East. The drying of moisture associated this
system has decreased the chances of precip with this system. The
areas with the chance of rain are the extreme Northern Cascades
and Northern Idaho. With the decrease of the precip chances, the
chance of thunderstorms has become next to nonexistent. The main
concern during this period will be the afternoon winds. The
thermal gradient is expected to tighten with the incoming system.
The winds along the valleys in the Cascades are expected to have
sustained around 20 MPH with gust near 35 MPH. Temperatures are
expected to be near the normal with highs in the 80s. /JDC
Friday through Monday: After a dry start to the period, a couple
features move on the region. First low pressure lingering off the
CA coast is projected to make its way inland Friday and skim by
southeast WA and the lower ID Panhandle Friday night into Saturday
night. Secondly a trough currently near the Aleutians moves toward
the coast by Friday night and gradually makes its way inland
through early next week, with impulses rounding it having
opportunity to move across the Cascades and northern mountains, if
not the entire region. There is disagreement on the strength and
track of these impulses. Overall, however, this will lead to an
increased threat of showers and thunderstorms across the mountains
and potentially the valley/basin area. The risk will increase as
the weekend progresses into early next week. Confidence is lowest
around the valley/basin areas. Temperatures will warm into
Saturday ahead of the trough, lingering near to just slightly
above normal, before dipping again into early next week. We will
also have to watch for another increase in winds Saturday,
possibly combined with lower RH values, for more fire weather
concerns. /J. Cote'

.AVIATION...
00Z TAFS: A broad canopy of ceilings ranging from 9-14k ft agl
associated with a weak wave moving NE through the area will
produce only light amnts of rain. This pcpn threat will end first
for the KEAT and KMWH TAF sites (as well as KLWS/KPUW) around
01-02z...then move out of the Spokane/ C'da area by 03-04z. As it
does, expect west and southwest winds to gust to 25kt for all
sites. These gusty winds will slowly decrease after 05z.
