.DISCUSSION...Widespread rain showers and scattered thunderstorms
will continue to develop and move from the northeast,to southeast
across the Northern Rockies this afternoon and evening. Some of 
these thunderstorms, especially in western Montana, could become 
strong, producing half inch size hail and gusty winds up to 35 
mph. Activity will diminish quickly after sunset, but wouldn't 
count out a couple stray showers produce a few lightning strikes 
across southwest Montana and Lemhi County through Wednesday 
morning.

A Canadian cold front will be sliding south across western Montana
Wednesday morning, that will bring cold enough air to produce
light snow for elevations above 6000 feet for southwest Montana 
and Lemhi County. Areas with the best chance for seeing any snow 
showers, will be Homestake and Lost Trail Passes, as well as 
Gilmore Summit and Bannock Pass in Lemhi County. Little to no 
accumulations are expected on the roadways, just be mindful of 
reduced visibility if traveling in these areas.

Wednesday will be slightly cooler throughout the region, as northeast
winds usher in a cool Canadian airmass. Scattered rain showers 
and thunderstorms are again expected, but not as widespread as 
today.

Thursday a ridge will build over the forecast area. Expect sunny 
skies and warming temperatures. It's been since Sept 9th last year
Missoula has hit 80 degrees. There is potential several areas
across western Montana will warm into the 80s. The lowest 
elevations of north- central Idaho, such as Riggins and Pittsburg 
Landing, could see temperatures into the low 90s those days.

.AVIATION...Expect Mostly cloudy conditions with scattered 
showers in the vicinity of all terminals. The possibility of VCTS
for MSO, BTM, and SMN will be present through 08/0100Z. Expect 
gusty erratic winds in and around showers. Overnight conditions 
will dry out, with showers redeveloping Wednesday afternoon.
