EF1 tornado in McCracken County, Kentucky

Peak winds were estimated near 100 mph. The damage began as trees were snapped just east of Melber on County Road 1820. Further northeast, a home near U.S. Highway 45 suffered damage as the garage was blown in and the porch was lifted up and damaged. This caused some damage to an interior wall inside the home. Numerous trees were snapped or uprooted, and tree limbs were broken off. Other homes near U.S. Highway 45 received shingle, siding, and gutter damage. Just south of St. Johns on the east side of Route 45, a camper was blown over and a few more homes had minor roof damage. Trees and tree limbs were blown down.

An outbreak of severe thunderstorms and isolated tornadoes occurred ahead of a cold front. Thunderstorms increased in coverage over southeast Missouri and then spread east-northeast into southern Illinois and western Kentucky during the late afternoon and evening. A surface low pressure wave over the Ozark Mountain region accelerated eastward in advance of a compact upper-level shortwave over the southern Plains. A mid-level dry slot overspread the surface warm sector, where dew points were in the low to mid 60's. Extremely strong wind shear compensated for weak instability. Strong forcing along the front and a moist low level air mass contributed to a forced line of storms, including some without lightning.
