A winter storm watch has been issued for central and southwestern Montana, with higher elevations expected to see up to a foot of fresh, summer snow.
...WINTER STORM WATCH REMAINS IN EFFECT FROM THIS EVENING THROUGH WEDNESDAY MORNING ABOVE 6000 FEET... * WHAT...Heavy snow possible above 6000 feet. Total snow accumulations of up to 8 inches. Locally higher amounts exceeding 12 inches are possible above 7500 feet. * WHERE...Elevations above 6000 feet in Beaverhead, Madison, Jefferson, and Gallatin Counties. * WHEN...From Tuesday evening through Wednesday morning. * IMPACTS...Travel could be difficult along roads entering mountain areas. Hazardous backcountry conditions. The weight of the snow on branches with foliage could cause them to break and produce isolated power outages. * Note...This Winter Storm Watch does not include the cities of Bozeman, Ennis, or Dillon.
The large, slow-moving storm system will produce widespread rain and mountain snow across the region through Thursday. The storm watch is in effect from 6 pm this evening through Thursday. Most of the precipitation today and tonight will spread across Southwest into central Montana as low as 5,500-feet.
Nonetheless, with most backcountry areas open to recreation, snow accumulations of even a few inches should be considered significant for this late in the season.
Temperatures will range from about 10 to 15 degrees below average.
