A mature mesoscale convective system progressed east-southeastward across the extreme southern tip of Illinois, producing pockets of wind damage. The well-developed cold pool in the wake of the system sustained its rapid forward motion. Steep mid-level lapse rates coupled with 20 to 35 knots of mid level flow resulted in pockets of damaging winds with the complex. Weak ascent within the southern branch of the jetstream supported the formation of the system. In its wake, temperatures in the 60's in the cold pool kept the movement of the system accelerating east-southeast.
