Winter-storm warnings and advisories have been issued for Thursday across most of Montana in anticipation of a storm moving in from British Columbia.
Billings and the surrounding area remained the only area not under either a warning or a watch as of Wednesday morning. That doesn't mean southcentral Montana will miss the moisture. That National Weather Service forecast for Thursday predicts three inches of snow.
But things could get ugly all around Billings. Northcentral and parts of Southcentral Montana will be under a warning from midnight tonight to 5 p.m. Thursday. The storm could bring four to eight inches to lower elevations and 16 inches in the mountains. The Weather Service warns that gusty north winds could cover roads with snow and reduce visibility to a quarter mile.
"Travel is strongly discouraged,” the Weather Service report said. "Roadways will become snow covered and slippery, with some roadways becoming impassible.”
A winter storm watch goes into effect this evening and will remain through Thursday afternoon. Four inches of snow is likely. Six inches is possible. Blowing and drifting may make driving hazardous.
In southeast Montana, the storm system will probably arrive on Thursday morning and stay until late that night. Four to six inches of snow is forecast, which may blow and drift with the winds.
Temperatures across Montana are expected to drop as the storm moves through the state.
