Another Hail Storm Strikes Northwest Iowa

445pm radarThe National Weather Service in Sioux Falls has issued a new Severe Thunderstorm Warning for Lyon, O’Brien, Osceola and Sioux Counties.  As you can see in the radar image from 4:45pm, a very strong thunderstorm with a prominent hail core is moving through this area.  This storm has a history of producing large hail over the last hour or two.

More storms are expected to develop tonight and will bear some watching.  A tornado watch is now in effect for a large portion of Nebraska and a Severe Thunderstorm Watch remains in effect for portions of northern Iowa for about another hour.
