Another late-season winter storm will affect Iowa very late tonight into Wednesday. Accumulating moderate to heavy snowfall is expected across the northern half of Iowa. Some freezing rain is also anticipated in some portions of central Iowa as well. The system should pass by Wednesday evening with improving conditions by then.

A winter storm warning will be in effect across northern Iowa from 4 am Wednesday to 1 am Thursday as heavy snow is expected. Total snow accumulations of 5 to 7 inches, with localized higher amounts, are anticipated within this warning. Some thunder may accompany the snowfall with high rates of 1 to 2 inches per hour.

Plan on difficult travel conditions, including during the morning commute on Wednesday. Expect significant reductions in visibility at times in part due to blowing snow and snowfall rates that may approach an inch per hour during periods of heavy snowfall. A Winter Storm Warning means significant amounts of snow, sleet, and ice will make travel very hazardous or impossible.
