(Radio Iowa) – A Snow Squall Warning was issued this (Thursday) morning for parts of western and central Iowa, due to visibility being greatly reduced by heavy snow. The D-O-T says many roads across Iowa’s western half are completely snow-covered. National Weather Service meteorologist Brooke Hagenhof says the storm system is headed east, roughly following Highway 30 and Interstate 80. “We’re looking at between two to four inches of snow falling across the area this morning, it’s going to fall very quickly within that band,” Hagenhoff says. “The heaviest snow looks to be along or maybe just north of that I-80 corridor as it moves across the state of Iowa.” She says a second winter storm may be looming this weekend.
