YANKTON, S.D.(WNAX)- While the current snow and ice storm exits the region, another system is taking shape for next week.

Alex Trellinger at the National Weather Service in Sioux Falls says this one will be bigger and moving slower.

Trellinger says the critical factor will be where the cold air sets up.

Trellinger says there could be areas of heavy rain and even thunderstorm.

Tim Masters at the National Weather Service in Sioux Falls says they expect a variety of precipitation.

Masters says while a winter storm, rain could be the main problem.

Masters says the storm will take its time moving through.

Some of the early maps show snow of a foot or more from Rapid City, through Pierre into the Aberdeen and Watertown areas. The storm could linger from late Monday into Thursday.
