Area Forecast Discussion
National Weather Service Spokane WA
1130 AM PDT Mon May 25 2020

.SYNOPSIS...
Rain will return for Memorial Day across Eastern Washington and
North Idaho with a chance of rain in Central Washington. Showers
will linger over north Idaho on Tuesday. A strong warming trend
is expected later this week with many locations expected to reach
the upper 80s to mid 90s. A chance of thunderstorms will develop
for the weekend.

.DISCUSSION...
Morning update to nudge down rainfall amounts a little bit. Latest
suite of model guidance from the 12Z runs have trended a little
bit drier. Accumulations will be highly orographic as there isn`t
much synoptic scale forcing to squeeze out rainfall out of this
fairly robust moisture plume. The mountains in the Panhandle will
see decent accumulations of around a quarter of an inch this
afternoon into tonight. The valleys across the Panhandle are
expected to see up to a tenth of an inch. Clouds will continue to
thicken up through today even across eastern Washington, but
rainfall will be very light with up to a few hundredths into
extreme eastern Washington and more like sprinkles out towards
Ritzville to Wenatchee. /SVH

.AVIATION...
18Z TAFS: A plume of Pacific moisture will be directed into the
region today, but rain will be very light over much of the region.
The Idaho Panhandle will see a better chance for rainfall and low
ceilings with MVFR conditions possible. I also can`t discount a
brief period of MVFR conditions out into KGEG, KSFF and KPUW late
this afternoon. The weak disturbance moving in aloft will push
across rather quickly with rain dissipating late this afternoon
across eastern Washington. Upslope showers will then continue
over the Panhandle into this evening. Expect mountain obscurations
with lowering ceilings through the afternoon. Low stratus with
MVFR conditions will be possible at KGEG, KSFF, KCOE and KPUW with
fog forming in the mountain valleys overnight as well. /SVH
