Area Forecast Discussion
National Weather Service Spokane WA
432 AM PDT Wed Jul 28 2021

.SYNOPSIS...

Above average temperatures are expected through the Saturday,
with highs well into the 90s with some triple digit temperatures
expected by the end of the week. Otherwise the forecast remains
dry and occasionally breezy. Wildfire smoke will continue to
impact portions of the Inland Northwest. Rainshowers and isolated
thunderstorms possible Sunday bringing a cooler start to next week.

.DISCUSSION...
Today and Thursday: The plume of monsoonal moisture has shifted
East as high pressure continues over the region. It will lead to
another dry, warming trend for the Inland Northwest. Sky cover
over Southeast Washington and the Lower ID Panhandle will clear
out through the early morning. Smoke and haze will continue to
impact the region from the wildfires. The 850MB temperatures
during the afternoon reach into the low to mid 20C. It translates
to surface temps of 90s to low 100s. Overnight lows are expected
to be upper 50s and 60s.

Friday: While the weather is not expected to be much different
from the previous days, the high temperatures for the day will be
widespread upper 90s and triple digits across the Inland
Northwest. Smoke from area wildfires could help shave a few
degrees from the highs but not expected to bring much relief from
the heat through Saturday. The lows are expected to be in the 70s.

Saturday through Wednesday: The upper level ridge will drive
temperatures up with highs in the triple digits across the region on
Saturday. Overnight there will be little relief from the heat, as
lows will be in the 70s. As monsoonal moisture moves further north
into the region, convection is possible in the southern Idaho
Panhandle Saturday evening. On Sunday afternoon, thunderstorms will
move into the region bringing rain and the potential for lightning.
However, fire weather concerns are low as lightning is unlikely to
start any new fires due to the rain and higher dewpoints expected.
Sunday night into early Monday morning also has the potential for
thunderstorms in the Idaho Panhandle. On Sunday, temperatures will
cool down to the low 90s with light winds across the region. These
temperatures and winds will remain the same for a few days. /KLE

.AVIATION...
12Z TAFS: A few lingering showers mainly over Idaho as the
monsoonal moisture band continues to shift east and exit the area
in the next few hours. A clearing trend expected as drier air
moves into the region. All TAF sites are expected to remain at VFR
conditions expected with limited impacts from haze or areas of
smoke. /JDC
