Weather conditions in western South Dakota will begin to improve Sunday evening and into Monday morning , according to the National Weather Service.
Rapid City and the surrounding area can expect light snow through Sunday afternoon without much accumulation, said David Barber, meteorologist with the NWS in Rapid City.
Barber said the main concern will be the continuation of strong winds with up to 50 mile-per-hour gusts.
"The blowing snow will not cause too much of a problem in town, but it will be worse outside of town where it's more open and they will see reduced visibility and lots of drifting snow," said Barber.
Portions of the northwestern area of the Black Hills have reported about a foot of snow and will continue to see snow accumulation throughout the day Sunday and into Monday morning.
East of Wall, however, is much worse with blizzard like conditions covering much of the state.
Interstate 90 between Wall and Chamberlain was closed and Interstate 29 between Exit 177 at Watertown, and the North Dakota border were closed early Sunday morning.
Terry Woster with the South Dakota Department of Public Safety said other road closures were possible because the weather forecasts anticipated continued snow and increasing winds that will make travel will be difficult to impossible at times.
Conditions are expected to improve Sunday night with the winds gradually subsiding and the snow ending by Monday morning.
