.DISCUSSION...
Evening update: WV/IR satellite shows the first shortwave
disturbance moving in through eastern OR and southeast WA. Showers
and thunderstorms are numerous over Oregon, but more isolated to
scattered in nature right now over eastern WA and the lower
Panhandle. The Oregon activity will begin to expand into southeast
WA and the lower Panhandle in the next few hours. The second
shortwave on its heels is coming into western Oregon/southwest WA
at this hour, which models show will expand additional showers
across central and eastern WA and north ID late overnight into
Tuesday. A forecast update was sent to increase PoPs, as well as
to raise QPF amounts slightly, and to expand the thunderstorm
threat to a broader area of east-central and southeast WA into the
central Panhandle. This includes the Spokane/C`dA area and Palouse
south into the L-C valley. Thunder, in general, is expected to
remain isolated save for perhaps the Camas Prairie where the more
numerous thunderstorms over northeast Oregon may track. /J. Cote`

.AVIATION...
00Z TAFS: A couple weather disturbances pass through the Inland NW
over the next 24 hours. Isolated -shra will be a risk early this
evening, through 02-03Z, with a few -tsra possible near PUW/LWS in
the afternoon heating. The 1st weather disturbance with a broader
shower threat comes in between late evening and Tuesday morning,
with scattered showers possible at all TAF sites. A brief lull is
expected in the mid to late morning, before the second disturbance
approaches in the afternoon and keeps the threat of showers alive.
VFR conditions are projected, but lcl MVFR conditions possible in
any heavier showers. /J. Cote`
