Discussion...
minor update to adjust pops across the southeast zones and the
Lower Basin. Regional radar mosaic shows a persistent band of
showers and thunderstorms tracking northeast from the NE blue
mts, across the Idaho Palouse and into western Shoshone County.
There are also a few cells popping up over the Lower Basin with
quite a bit of convection to the south that will track north over
the next few hours. Cells are generally weakening as they move
north into the forecast area. So far only light to moderate
showers over the Cascade fires. There may be some stronger cells
tracking over the fires later tonight or they may track just
barely to the east of the fires. /Kelch

Aviation...
00z tafs: a low pressure system circulating off of southeast British Columbia
will continue to push moisture across the inland northwest with
showers and thunderstorms affecting all taf sites. The strongest
thunderstorms are expected to develop over northeast or and track
into southeast Washington and into the central portions of the Idaho
Panhandle. Gusty outflow winds and small hail will be possible
with these thunderstorms through the evening. Scattered showers
and isolated thunderstorms will continue overnight but confidence
is low that they will affect any particular taf site. -Tsra will
be more widespread Wednesday afternoon with thunderstorms capable
of producing heavy rain, small hail and gusty outflow winds. /Ek
