Parts of Iowa, Nebraska slathered with slushy snow

May 2nd, 2013 by Ric Hanson

OMAHA, Neb. (AP) – A spring storm has slathered a heavy icing of slushy snow on parts of eastern Nebraska and western and north-central Iowa.  Our 24-hour snowfall total in Atlantic as of 7-a.m. was 2-inches.

In the past 12 hours, more than 6 inches has been recorded in isolated parts of Iowa, including Harrison County near Omaha, Neb., and along the Minnesota border in northern Iowa.  Nebraska totals are generally lower.

National Weather Service meteorologist Josh Boustead called the May storm “really, really unusual.”  He says that in Omaha, for example, measurable snow has fallen only four times since 1884.  The storm is moving east and is expected to lay a wet blanket on Des Moines later Thursday.
