The National Weather Service has issued a Winter Weather Advisory for parts of South Dakota, including Sioux Falls. The advisory is in effect from 8:00 AM until 6:00 PM on Thursday.

A winter weather system is expected to move into the area Thursday, bringing a wintry mix of rain, freezing rain, slee,t and snow. This could create icing on roads and make travel difficult.

"More wintry precipitation will spread into the area by later Wednesday night and Thursday. While precipitation will start as light snow, many areas near and east of the James River valley will see a mix or change to light freezing rain which is likely to result in a glaze of icing on Thursday. Some shifts to locations of expected ice and snow are still possible. Be sure to keep an eye on road conditions," - NWS
