A clipper system moving into the upper Midwest coupled with low pressure across Southeast caused severe thunderstorms to develop during the early morning hours of February 18th across south central Kentucky. A dry slot moved across the area during the morning hours and sufficient heating allowed the atmosphere to destabilize as a cold front moved across central Illinois into Indiana and Kentucky. Thunderstorms redeveloped during the late morning and afternoon hours. Severe hail was the biggest threat with these storms despite a few tornado warnings being issued. Areas most effected were across south central Kentucky near the Kentucky and Tennessee border with a few reports just south of Lexington. Hail size reports ranged from penny size to golf ball size.
