Severe thunderstorms developed from Minnesota through Arkansas on the late afternoon of March 6th and marched eastward into the night. A quasi-linear convective system (QLCS) had evolved across central to eastern Iowa, and continued east into northern Illinois. While this showed a gradual weakening trend across the forecast area, it still had scattered severe winds (60+) among widespread 40-60 mph winds. |
