Winter Storm Maps Show Where State Could Be Hit With 7 Inches of Snow

Residents of Montana could be hit by unseasonably cold weather and snow starting on Sunday, the National Weather Service (NWS) has reported.

Montanans in some parts of the state can expect chilly temperatures and snow throughout Sunday and into early next week. Winter weather advisories are in place across numerous areas currently, while temperatures are expected to drop close to or below freezing.

From 6 p.m. on Sunday, those in Big Belt, Bridger and Castle Mountains, Elkhorn and Boulder Mountains, Little Belt and Highwood Mountains, Gallatin and Madison County Mountains and Centennial Mountains, and Northwest Beaverhead County can expect up to 7 inches of “heavy, wet snow,” particularly at higher elevations above 6,000 feet, according to a winter weather advisory issued by the NWS.

“Travel could be difficult, especially on backcountry roads. Those in the backcountry should ensure they have appropriate knowledge and gear and may want to consider alternate plans,” the advisory reads. “The heavy, wet nature of snow can bring down tree limbs and power lines.”

Another advisory warns of 6 inches of snow for those in the East Glacier Park Region and along the Southern Rocky Mountain Front, particularly in areas between 6,000 and 8,000 feet. Both advisories are currently in place until Tuesday evening.

Those in Missoula and Bitterroot Valley are also subject to a winter storm watch advisory, with 3 inches of heavy, wet snow expected to fall on Sunday night through to Monday morning. During the same period, 1 to 5 inches of snow is forecast at Georgetown Lake, Macdonald Pass and along Highway 12, with five to 12 inches possible in the highest terrain.

Similar conditions are also expected overnight on Sunday along several roads, including the I-90 East Missoula to Bearmouth, Highway 200 from Bonner to Greenough, and Highway 83 from Seeley Lake to Condon. Motorists are encouraged to “slow down and use caution” while on the road.

Residents of the areas covered by the warnings are warned of the risk of hypothermia if heading out unprepared, with temperatures expected to drop to the low 30s. Overnight, the NWS X, formerly Twitter, account said “temperatures will be dropping into the 30s tonight across valley areas,” which could also have an adverse effect on plants as frost forms.

While Montanans feel the chill, other parts of the U.S. are expecting more predictable warm weather for this time of year. Excessive heat watch warnings are in place in the Midwest, and also Connecticut, Indiana, Maine, Michigan, Ohio, Pennsylvania, and West Virginia. Further south in Texas and New Mexico, heat advisories are also in place.
