A warm front lifting northward into central Illinois triggered clusters of strong to severe thunderstorms during the late evening of May 6th into the early morning of May 7th.  The initial cluster tracked through the Illinois River Valley east-southeastward toward Champaign...generally along and north of I-72.  Additional cells developed in its wake along and north of the front, eventually congealing into a linear structure that dropped southeastward into Indiana by mid-morning.  Scattered wind damage and hail as large as quarters occurred with the storms.  In addition, isolated flash flooding was reported across southern McLean County where training cells dropped 2 to 3 inches of rain.
