.DISCUSSION...A very slow moving low pressure system is spinning
over the Northern Rockies. Afternoon heating has triggered
numerous showers and thunderstorms over the region.The main
impact will be the potential for heavy rain in a short time.
which will die off after sunset. .

Thursday will be another showery day across the Northern Rockies.
The best chances for lightning will be east of Hwy 93. Any storms
that form will again be slow-moving since flow aloft is weak.

Chances for precipitation remain for Friday through the weekend,
as moisture moves along a weak ridge. These showers will be less
widespread than on previous days. By Sunday, temperatures will
warm, and Missoula, Kalispell, and the Camas Prairie of Idaho
could see 80 degrees for the first time this year.

A low pressure system moves into the Oregon coast on Monday.
Ahead of this system, southwest flow and a weak jet streak aloft
will put north central Idaho and western Montana in a favorable
situation for stronger thunderstorms. This threat lasts into
Tuesday, but thunderstorms will follow their diurnal cycle, with
the strongest possible in the late afternoons and evenings.


&&

.AVIATION...Scattered showers and thunderstorms will occur at all
terminals through 28/0400z. Some storms could produce significant
brief heavy rains as well as mountain obscurations.
