...Severe Weather Affects the Region Once Again- May 13, 2009...

May 13, 2009 Event Overview

 A line of strong to severe thunderstorms developed and pushed across southeast Kansas and southwest Missouri during the afternoon and evening hours of May 13, 2009.  Thunderstorms rapidly developed and became severe as a slow moving cold front interacted with a warm, moist, and very unstable atmosphere Wednesday afternoon.  Storms initially took on both supercell and line segment characteristics with large hail, damaging winds, and heavy rainfall.  As slightly stonger vertical wind shear worked its way into the thunderstorm environment, a few of these storms began to exhibit strong rotation and a few reports of tornadoes were received (See Storm Reports Below).  The storms eventually merged into a solid line of thunderstorms with damaging wind and large hail being the primary threats, and eventually moved off into Arkansas and southeast Missouri.  NWS Storm survey crews are assessing the damage today.
