Severe Storms, Heavy Rain Today
Monday, June 16, 2014 @ 6:18 am
Severe thunderstorms and heavy rain are possible across much of our region again today. Storms will develop in two rounds. The first will develop across Nebraska early this morning and move northeast into south-central and southeast South Dakota by mid morning. Large hail and damaging straight-line wind gusts will be the primary severe threat with storms that develop this morning.
Round two will happen this afternoon as storms redevelop across eastern South Dakota and move into southern Minnesota and northern Iowa. Development of afternoon storms will depend largely on what happens with our first round of storms this morning. If the morning storms hold together, they could flush out some of the potential energy for storms this afternoon. If not, explosive development of thunderstorms is possible this afternoon and evening.
The atmosphere will be very unstable and packed with moisture this afternoon and the dynamics will be present for strong, supercell thunderstorms capable of producing large hail, damaging wind gusts, and tornadoes. In addition to severe weather, the significant amount of moisture in the atmosphere means the potential for very heavy rain in places that have already had more than they can handle. Flash flooding will, once again, be possible in many places.
Stay weather aware today. Be sure you have a means of staying in touch with changing weather conditions because things could happen very quickly later today.
