Episode Narrative Western Kentucky was located in the destabilizing warm sector of a surface low across northern Missouri. Mixed layer CAPE values at or above 1000 j/kg aided thunderstorm intensification as large scale lift was maintained ahead of the surface low. Deep-layer wind shear on the order of 40 to 50 knots contributed to persistent rotating updrafts. A few tornadoes occurred with rotating storms that crossed a warm front draped across southern parts of western Kentucky.
Event Narrative A few dozen trees were uprooted, and numerous large limbs were broken. Minor shingle damage was noted on one home. A small area of corn was flattened. Peak winds were estimated at 95 mph.
