The National Weather Service has issued a Winter Storm Watch for West River and Central South Dakota from late Thursday night into Saturday.
Rapid City meteorologist Shane Egan says all of South Dakota may see impacts from this system. He says heavy snow and strong winds are possible over a wide swath of the state.
"Pierre to Wall and down into kind of Pine Ridge area, with upwards of a foot or so...maybe more. A lot of kind of South Central into Western South Dakota could see up to 60 mile per hour gusts," Egan says.
Egan says snow is forecast to begin in northwestern South Dakota and move to the east throughout Thursday morning. He says snow should leave western and central parts of the State by daybreak Saturday.
Egan says highs are forecast to top out in the 20s and 30s with lows mainly in the teens.
