Supercell thunderstorms developed along an outflow boundary from central Missouri into south-central Illinois along the I-70 corridor during the late afternoon and evening of May 26th. The storms eventually congealed into a line and swept eastward, causing significant wind damage across the southern portions of Clay, Richland, and Lawrence counties. Damage surveys revealed two tornadoes touched down...an EF-2 in Clay County northwest of Xenia and an EF-1 in Lawrence County south of Sumner.
