Round 1 of Severe Weather - June 3-4, 2008

June 3, 2008
Round 1 of Severe Weather - Tuesday Afternoon

The first round of severe weather came from a long-lived mesoscale convective system which originated in Illinois. The bow-shaped line of storms moved east-southeast at a high rate of speed, entering the Wilmington County warning area (CWA) shortly before 3 PM. The line of storms was responsible for wind damage in many locations, and also some marginally severe hail. Two locations which received damage of higher significance were Dillsboro, Indiana (Dearborn County) and near Mount Olivet, Kentucky (Robertson County). The line of storms exited the Wilmington CWA at around 5 PM.

Radar Pictures From Event #1

At 3:20 PM, the line of storms began pushing into Ohio. Intense reflectivities (left) were detected with the cell in southern Dearborn County, Indiana. Velocity data (right) shows velocity data, with very strong inbound (green) winds of 60-70 knots detected.

At 3:46 PM, the line continued pushing eastward. While strong winds were reported with the bowing area in Ohio, the strongest cells remained in Kentucky. Reflectivity (left) and velocity (right) data both show intense storms across Boone and Kenton Counties.

At 3:48 PM, the strongest cells as seen on reflectivity data (left) were located over Bracken, Mason, and Robertson Counties in Kentucky. Storm relative motion data (right) shows a strong MARC (mid-altitude radial convergence) signature in the mid-levels of this storm. This likely led to enhanced wind damage across northern Robertson County. Some rotation is also evident, indicating a mid-level mesocyclone, which is to be expected in an intense storm such as this one.
