The National Weather Service (NWS) offices in Johnston have upgraded their forecast to a winter storm warning for the Perry area from 6 a.m. Monday to 6 a.m. Tuesday, with 8-12 inches of blowing snow.
Heavy snowfall rates are particularly likely Monday afternoon, the NWS said, and increasing northeast winds might gust over 30 mph at times and cause moderate blowing and drifting.
The NWS said three winter systems will impact Iowa through midweek, with the first two, and especially second, the most significant. The first storm front will produce light to moderate snow, possibly switching to a wintry mix, across central and northern Iowa Sunday night.
The second and larger winter storm will follow Monday, with widespread moderate to heavy and blowing snow across central and southern Iowa. A third, weaker system is also anticipated late Tuesday into Wednesday morning.
Monday travel could be very difficult, the NWS said. Blowing snow could significantly reduce visibility. The hazardous conditions could especially hamper the Monday evening commute.
Along with Dallas County, Iowa counties in the winter storm warning include Polk, Jasper, Poweshiek, Cass, Adair, Madison, Warren, Marion, Mahaska, Adams, Union, Clarke, Lucas, Monroe, Wapello, Taylor, Ringgold, Decatur, Wayne, Appanoose and Davis.
Along with Perry, cities in the winter storm warning include Waukee, Adel, Des Moines, Newton, Grinnell, Atlantic, Greenfield, Stuart, Adair, Fontanelle, Winterset, Earlham, Indianola, Norwalk, Carlisle, Pella, Knoxville, Oskaloosa, Corning, Creston, Osceola, Chariton, Albia, Ottumwa, Bedford, Lenox, New Market, Mount Ayr, Lamoni, Leon, Corydon, Seymour, Allerton, Humeston, Centerville and Bloomfield.
