Two rounds of strong to severe thunderstorms impacted central Illinois during the afternoon and evening of July 11th.  The first round developed along an outflow boundary from previous convection that had tracked across northern Illinois around midday.  These cells formed along the I-74 corridor and brought large hail and locally heavy rainfall during the late afternoon hours.  Hail as large as tennis balls or 2.5 inches in diameter was reported in Bartonville in Peoria County.  Meanwhile, hailstones as large as 2 inches in diameter caused considerable damage to car dealerships in Savoy and numerous roofs on the east side of Urbana in Champaign County.  The second round of storms developed over eastern Iowa, then swept southeastward across much of the area during the evening bringing damaging wind gusts.
