Synopsis...
a slow moving low pressure system will bring scattered afternoon
and evening thunderstorms to the inland northwest today through
Wednesday. Locally heavy downpours, frequent lightning, and small
hail will be possible the next several days. Low pressure will
gradually depart by Thursday bringing a decrease in precipitation
chances. Next weekend looks like it will be quite warm with
afternoon temperatures well into the 80s.

Discussion...
just a quick update for today. An upper level low sits just north
of the Cascades. Main frontal band is pushing across north Idaho
with scattered mid level showers with embedded thunderstorms.
Expect convection to increase through midday especially in the
vicinity of the low as it drops into north central Washington
numerous showers and isolated/scattered thunderstorms are
expected. Main threat from these slow moving storms will be heavy
downpours and possible ponding of water, along with lightning,
small hail and gusty winds. The thunder threat will decrease
slightly this evening, although the close proximity of the low
will keep showers through the night. /Rfox

Aviation...
18z tafs: a mid level cold front will exit north Idaho by midday,
allowing the band of showers with embedded thunderstorms to push
east into Montana. The moist boundary layer and dewpoints in the
mid 40s to lower 50s will aid in the redevelopment of convection
behind the front. The best areas for convection will be across the
northern mountains, but as the storms drift south-southeast,
expect some activity reaching the taf sites this afternoon and
early evening. Isolated to scattered showers will persist over
much of the region through 18z Tuesday as the low center remains
over the region. /Rfox
