The U.S. National Weather Service (NWS) issued a Winter Storm Warning about 10 p.m. Sunday for the Iowa counties of Adair, Audubon, Cass, Dallas and Guthrie. The Winter Storm Warning will remain in effect until 6 p.m. Monday.
Travel during this period is expected to be very hazardous or impossible, according to the NWS.
A significant storm system is bringing a variety of winter weather across the northwest half of Iowa on Monday and into Tuesday. Winter precipitation spread into central Iowa Sunday night and will continue Monday before diminishing by late Monday afternoon.
The NWS said areas of freezing rain developed over portions of Iowa late Sunday. The precipitation is expected to change to all snow Monday morning. Monday morning and Monday afternoon will see the heaviest snowfall, with precipitation rates diminishing into the late afternoon.
Snow accumulations are expected to range from 1 to 3 inches. Ice accumulations between .2 inches and .3 inches are expected through Monday morning before a transition to all snow occurs.
Winds will be easterly at 10 to 15 mph.
Ice and then snow accumulations will lead to hazardous travel conditions and may especially impact Monday morning commuters. The heavy, wet snow will also be difficult to shovel and remove.
There will be some threat of light freezing rain or snow Monday night and Tuesday, although amounts appear very light by that time, according to the NWS.
