... Winter Storm Watch in effect from Friday afternoon through
The National Weather Service in Missoula has issued a Winter
Storm Watch... which is in effect from Friday afternoon through
* Impacts/timing: a moisture plume will cause widespread
precipitation starting late Friday through Saturday. This
moisture will interact with a strong Arctic front pushing
southward out of Canada. The front will cause snow levels to
drop dramatically. Many valley locations will receive
rain... which will then change to snow... followed by very cold
temperatures. Strong easterly winds are anticipated with the
Arctic front, which could cause areas of blowing and drifting
snow. Areas east of Highway 93... from Eureka to Arlee... are
anticipated to receive the biggest impact from this system.
* Snow accumulations: valleys: 3 to 6 inches possible... locally up
to 9 inches in the Glacier park area. Mountains: 8 to 16 inches
possible by Saturday afternoon.
* Winds: east 20 to 30 mph with gusts up to 45 mph possible near
the mouth of favored canyons... such as badrock.
* Locations impacted include... Highway 93 Eureka to
Whitefish... bad Rock Canyon... Essex... Highway 83 Bigfork to
Swan Lake... Marias Pass... Polebridge... Flathead Lake... Flathead
Valley... Mission Valley... Polson... Highway 200 Bonner to
Greenough... Highway 83 Seeley Lake to Condon
