Area Forecast Discussion
National Weather Service Spokane WA
221 PM PDT Mon Aug 8 2022
.SYNOPSIS...
One more hot day is expected as a ridge of high pressure remains
over the Inland Northwest. Expect daytime highs in the 90s to
triple digits again on Tuesday with an increase of high clouds.
The threat of thunderstorms arrives Tuesday night into Wednesday
and Thursday with little if any rain and and locally gusty winds.
Temperatures gradually moderate by the weekend with a return of
dry and breezy conditions.

.DISCUSSION...
Tonight through Wednesday night: A ridge of high pressure over the
Inland NW will slowly dampen as a slowly moving cutoff low off
the California coast drifts north along the West Coast. This will
bring a short-lived heatwave to the region and locally breezy
winds. As the upper level flow becomes more southerly by Tuesday,
an increase of mid level moisture to this unstable environment
looks to bring light showers and the potential thunderstorms
across the region.
Temperatures: The heat is evident this afternoon with temperatures
running 4 to 8 degrees warmer than yesterday under the clear
skies. Daytime highs should top out in the 90s to the triple
digits and this will repeat again on Tuesday. Clouds arriving by
Tuesday will thicken and this may hamper some locations on
reaching their potentials and high temperatures were shaved down a
couple degrees cooler in central WA. Yet it will still be hot
region-wide. Most temperatures may be shy of breaking any records,
yet heat risk levels will reach moderate to high levels through
Tuesday. Excessive Heat Warnings and Heat Advisories remain in
effect through Tuesday evening. Overnight lows will see a warming
as well especially Tuesday night as cloud cover increases and
limits radiation cooling with lows in mid 60s to lower 70s.
Temperatures lower about 5 degrees on Wednesday with daytime highs
still quite warm in the 90s.
Winds: High pressure at the surface will give way to light terrain
driven winds overnight. Down-slope winds increase in the Cascades
by this evening into the Waterville Plateau and Columbia Basin
with localized gusts of 15-20 mph and raising fire weather
concerns under the dry conditions. This pattern will return again
Tuesday evening with more widespread breezy winds by Wednesday
evening.
Thunderstorms: Mid and high moisture moves in from the south
overnight into Tuesday mainly across central Washington. The
remnants of convection will drift across the Cascades by Tuesday
morning, giving way to some sprinkles. Another round of convection
Tuesday afternoon should roll northward into central and eastern
Washington Tuesday evening and track through the Inland NW
overnight. There is the potential of occasional lightning, gusty
erratic winds and little if any precipitation from these storms.
Another round of convection can be expected Wednesday afternoon
and evening, especially across the northern Cascades and the Blue
mountains. Instability will be elevated with the storms on
Wednesday with the potential of strong gusty winds and scattered
lightning. This will elevate fire weather concerns with the threat
of fire starts. /rfox.
Thursday and Friday: The low continues to work its way up the
Washington coast before moving east over BC late Friday. Thursday
will remain quiet with above normal temperatures before a shortwave
moves through Friday afternoon. Have brought a slight chance of
thunderstorms into the forecast for the Idaho Panhandle on Friday
afternoon and evening. These thunderstorms, similar to Wednesday,
will be quick moving and little to no precip. New fire starts are
possible. High temperatures will remain in the 90s.
Saturday: Moving into Saturday, the chance of thunderstorms
increases over the mountainous terrain again, this time with the
addition of breezy winds as the gradient tightens from the low to
the north. Winds will gust up to 30 mph across central Washington.
Thunderstorms that form will again be moving quick and with little
precip. New fire starts are possible and with the breezy conditions,
fires could spread quickly. High temperatures will remain in the 90s.
Sunday and Monday: As the low exits, ridging will try to build back
into the PacNW but there is uncertainty with this. Some ensembles
are hinting at a shortwave passing over on Sunday but there is quite
a bit of uncertainty on if that will occur. Have left a slight
chance of thunderstorms in the forecast for Sunday over the
mountains in northwest Okanogan county. High temperatures will
warm slightly but remain in the 90s. /KM

.AVIATION...
00Z TAFs: VFR conditions will continue through the period. Clear
skies are expected for much of the day and then mid and high
clouds spread into the region from the south overnight ahead of
an area of low pressure. Terrain driven winds of 10 MPH or less
are expected for most of the region. There is the potential for
light showers or virga spreading across the Cascades Tuesday
morning from the mid cloud deck. Afternoon convection will drift
into across the lower Columbia Basin to the southeast Washington
by late Wednesday afternoon. /rfox.
