CHEYENNE, Wyo. (AP) — The first major winter storm of the season is headed to the Rockies, bringing snow and bitter cold to Montana and Wyoming.

The National Weather Service has issued winter storm warnings for most of Montana. Winter weather advisories are posted for the northern half of Wyoming.

Rain changing to snow will be the story Monday as the remnants of a Pacific typhoon that blasted Alaska with winds close to 100 mph work their way into the region.

Much of Montana will see several inches of snow, with upward of 10 inches possible in the mountains. Lesser amounts are forecast in Wyoming before the storm moves out by Wednesday.

Temperatures region wide will dip below zero, with highs in the teens and single digits forecast through Thursday.
