Area Forecast Discussion
National Weather Service Spokane WA
225 AM PDT Thu Aug 25 2022
.SYNOPSIS...
Scattered showers and thunderstorms will impact the Inland
Northwest through Thursday evening. While some areas may not see
a drop of rain, other areas may see strong storms with heavy
downpours, hail, gusty winds and lightning. Drier and locally
breezy weather arrives Friday through the weekend. Temperatures
will remain warm into Friday, cooling off over the weekend, and
then warming up again next week.
&&
.DISCUSSION...
Today through Friday Night: A closed low over the Spokane area
early this morning will lift northeast into N Idaho this
morning...and then into southern Alberta in the evening. Elevated
instability ahead of the low will continue to trigger scattered
showers with embedded thunderstorms into the early morning before
this activity begins to push out of the area. Then attention
shifts to afternoon convection. Plenty of lingering moisture with
PWAT's near 150% of normal, afternoon heating, and steep lapse
rates will lead to surface based convection in the form of
scattered showers and thunderstorms. The best focus will be over
the northern mountains into the ID Panhandle. The northwest flow
on the back side of the low will likely allow some of this
activity to come off the higher terrain into the Upper Columbia
Basin and Spokane/Coeur d'Alene areas by late this afternoon into
the evening. The instability isn't quite as great as yesterday
with HREF showing CAPE values of 500-800 J/KG, but the slow
movement will lead to locally heavy rain. This convection will die
down after sunset with the loss of daytime heating, as well as a
short wave ridge moving over the region overnight into Friday
morning. The short wave ridge will lead to a drier day on Friday,
although still enough residual moisture and instability over far
NE WA/ID Panhandle for a threat of a few showers or thunderstorm
mainly in the mountains. A weather system dropping down over
Vancouver Island Friday night will help tighten the cross-Cascade
pressure gradient leading to breezy winds in the lee of the
Cascades. Relative humidity looks to remain above critical
thresholds but the winds will result in the potential for
increased fire spread with any new or existing fires. JW
Saturday and Sunday:
Temperatures briefly return to late August averages near 80
degrees this weekend as an upper level low over SW OR moves SE
into our area. 24 percent of the ensemble (primarily GEFS members)
has the trough axis many hundred miles east in central ID. If
that were the case, our high temperatures may not exceed 70 in
some spots Saturday. There may be some showers in the higher
terrain of the cascades, but PWATs and forcing with this trough
are meager. Winds will be breezy through the morning and early
afternoon, but decreasing in the late afternoon/early evening.
Sunday will also remain on the cooler side, especially if the low
lingers in our region. Uncertainty rises with high temperatures
Sunday since it highly depends on the position of the low. 87
percent of the ensemble (primarily GFS and Euro members) develop a
very deep trough SE of Alaska which positively amplifies the
downstream height field.
Monday through Thursday:
Ridging keeps our temperatures approximately 8 to 15 degrees above normal
through Wednesday. High temperatures would range from the mid 80s
to near 100 degrees. We will remain dry and sunny during this
period. Thursday becomes more uncertain with an upper level low
looming off the coast, but will likely be cooler as height falls
occur. /db

.AVIATION...
12Z TAFs: As the best elevated instability shifts east of the
region this morning attention will turn to the redevelopment of
showers and thunderstorms this afternoon. The bulk of the activity
is expected over the northern mountains into the ID Panhandle but
the northwest flow may allow some storms to come off the mountains
into the Spokane/Coeur d'Alene areas. VFR conditions are expected
over the region except for some visibility restrictions under
heavier showers and thunderstorms. This activity will diminish
after sunset. JW
