North Dakota and Western/Central SD are getting the worst of it. Sioux Falls is just getting a bit of wind and maybe some snow, so we're OK.
Governor Rounds of SD is meeting with staff. Interstate 90 (major east-west route across the state) is closed. I-29 (north-south) might close in a bit. Reports of snow several feet deep in the Black Hills, with wind gusts up to 70 mph on parts of the Plains.
Please pray for all people here, and for public safety, utility and transportation folks.
