.DISCUSSION...
Tonight: A shortwave trough is currently pushing across the
Inland Northwest. It is producing isolated thunderstorms and
showers along the Canadian Border and Lower ID Panhandle. The
thunderstorms have a chance of producing gusty winds, small
hail, brief heavy rain, and lightning. The gusty wind speeds
will range between 25-30 mph.  As the evening settles in over
the region, the activity will diminish with a stabilizing
environment. Overnight lows are expected to be in the 50s and
low 60s.
Monday through Thursday: Models continue to keep the upper-low
parked over the Northwest through much of the week. Temperatures
will be trending cooler with increased humidity. Just about
every day from Monday through Wednesday carries some degree of
precipitation chances. Currently, the highest probabilities for
wetting rains arrives Monday night into Tuesday when the
strongest dynamics lift into the area delivering a 40-60% chance
for a tenth or more. Precip amounts range from a tenth or two
for the lowlands and a quarter to 3 quarters of an inch for the
higher terrains. The thunderstorm threat has weakened from
previous runs but will still need to keep an eye on it. Highs
will be in the 70s. Lows will be in the 50s.
The low will fill and begin to drift out the region Friday as
another low approaches the coast. A ridge will build in between
the two lows. It will start a drying trend for the region and
into the weekend. With less sun time, temperatures are expected
to remain mild and near season normals. Highs will be in the 70s
and lows will be in the 50s. /JDC
