Bands and clusters of strong to severe thunderstorms produced isolated reports of damaging winds and tornadoes. A fast-moving upper level trough tracked east-northeastward from the central Plains into the upper Midwest. Strong south-southwesterly low level winds across the Mississippi Valley transported Gulf moisture rapidly northward. Thunderstorms increased along and south of a warm front draped across southern Illinois extending into northern Kentucky. Low level shear was moderately strong in the vicinity of the warm front, contributing to the isolated tornadoes.
