A significant severe weather outbreak is expected from Arkansas/Louisiana to Alabama today with the Storm Prediction Center issuing its highest threat category for its categorical "Day 1 Convective Outlook" of "High Risk". The featured map presents the frequency of High Risk according to unofficial IEM data back to 2002 valid for the morning issuance. These events are rather infrequent with the highest values shown over northeastern Kansas with a rate of about one per every 3 years. The last high risk covering any portion of Iowa was back on 3 June 2014.
