Snow ending by Sunday night


A storm system has brought snow to much of western Montana.

It will exit the state Sunday night. The WINTER WEATHER ADVISORY will expire Sunday evening in areas west of the divide, including the Missoula and Butte areas where additional light snow will be possible.

WINTER WEATHER ADVISORY through early Monday morning east of the divide, including the Bozeman area and a WINTER STORM WARNING above 5500 feet in Gallatin and Madison Counties. Snowfall of 1 to 5 inches below 5500 feet and 6 to 12 inches above 5500 feet, including Bozeman Pass, West Yellowstone and Big Sky.

Lows will drop to the single digits and 10s in the Butte and Bozeman areas and the 20s in the Missoula and Kalispell areas.

Lingering snow south of I-90 in the Bozeman area early Monday, then decreasing clouds elsewhere. Highs in the 20s to lower 30s.

Strong high pressure will build into the region the rest of the week. That means sunshine in the higher elevations and all areas east of the divide, including Bozeman.

However, inversions will develop in the valleys west of the divide. That means fog will form and in some cases, such as the Mission Valley, the sun will be blocked by low clouds and valley fog. Missoula will also be experiencing stronger valley inversions. Black ice will be possible on roadways.

Highs will be in the 20s and 30s with lows in the single digits and 10s.
