Wintry blast closes schools, plunges temperatures in Rockies

HELENA, Mont. - Some schools in Montana took their earliest snow day in memory Monday after a blizzard dumped several feet of snow, while plunging temperatures threatened crops across other parts of the Rocky Mountains in an unusually early blast of wintry weather.

Freeze warnings were in effect in parts of Utah and Idaho, and temperatures were expected to drop into the teens and 20s in those states and Montana overnight and Tuesday morning. The cold set in with the lingering fall storm system that dumped snow for three days across much of central and western Montana, including over 4 feet (1 meter) on the Blackfeet Reservation and Glacier National Park.
