The closure went into effect at 9 p.m.
Before the closure, driving conditions were labeled severe, due to "snow and ice were reported on the road, in addition to "very high winds," blowing and drifting snow, poor visibility and heavy snowfall, according to an email from Diana Walker, an MDT road reporter in Billings.
A cold front brought snow to the area Friday evening. The front has since moved on, but was followed by winds out of the northwest, said Julie Arthur, a meteorologist with the National Weather Service in Billings. Winds in the area were measured at 23 mph, with gusts of 28 mph as of about 8 p.m.
"It sounds pretty bad to be driving in," Arthur said. The temperature at Harlowton was at 18 degrees by 7 p.m. and Arthur said it's possible it has dropped into the single digits since then.
The same cold front is expected to arrive in Billings Friday night sometime between 10 p.m. and midnight. Snowfall overnight could total 1.5 inches, with an additional 1.5 possible by noon on Saturday, Arthur said.
