A powerful pacific winter storm system will spread heavy snow across the region late today through Saturday. Snow will impact Western Montana this morning, spreading eastward through the day. Highs will be in the 30s to low 40s, with rain, or a rain/snow mix possible during the day. A cold front swings through the area this evening, and then we get serious about making some snow.
Temperatures will drop to the single digits above and below zero overnight, with colder wind chills. Areas of gusty winds, especially east of Billings, will cause blowing snow and bitter wind chills.
Snow totals will vary from between 6 to 16 inches across Southern Montana, with a foot to two feet in the mountains.
The snow will start to pull out of Billings by late in the day Friday, but could linger snow showers in Eastern Montana through Saturday morning. As the snow leaves, the cold will remain.
