A thick grey fills the windscreen as Matthew Dux, a meteorologist at the National Weather Service in Sioux Falls, drives down a road, street lights, road signs and other vehicles only appearing at close quarters.
"It is not great at all out there!" Dux said in the Twitter post accompanying the video, which he said was taken south of the Sioux Falls airport. "Far too many people on the roads. No lights on, driving way too fast."
