Snow showers to produce quick accumulations Sunday


Scattered showers packing heavy snow will begin to impact areas north and west of Missoula Saturday night and continue through Sunday.

WINTER STORM WARNING for I-90 from Lookout Pass to Haugan, Evaro Hill, and Highway 200 from Plains to the Idaho state line through Sunday morning for quickly accumulating snow. Snowfall rates of 1 to 2 inches per hour with these showers will cause rapidly changing conditions out on the roads. Lookout Pass to Haugan will see 4 to 8 inches by midday Sunday while Valleys will see 1 to 4 inches.

The same snow that will impact Mineral and Sanders counties will also impact the Flathead. A WINTER WEATHER ADVISORY is in effect for Flathead, Lincoln, Missoula, and Lake counties through Sunday morning. Most valleys will see 1 to 4 inches while Glacier Park and the Swan Valley could see up to 6 inches.

In southwest Montana light snowfall is possible through the day and accumulations will be less than further north, around an inch with up to 2 inches under the heaviest showers. Bozeman will see a mix of rain and snow.

Temperatures will be around freezing Sunday morning and rise to the upper 30s to mid 40s in the afternoon. Colder weather is coming for Monday with highs only the 20s and 30s. That means that the scattered showers around the region on Monday will be all snow.

We begin to warm again midweek ahead of another storm that will once again impact mainly the Flathead Wednesday and Thursday. A cold front late Thursday or early Friday will switch us over from rain to snow and set us up for what could be a snowy couple of days next weekend.
