Description:

Note the eliptical shaped fine line extending in an north-south arc along the western flank of the developing convection. This outflow boundary orginated from a strong storm that developed earlier in the afternoon over Paulding county Ohio. In addition...at the beginning of the loop...an even older left over storm scale outflow boundary had stalled out along a Goshen to Fort Wayne line. As the Ohio outflow pushed westward and collided with the stalled out outflow...low level convergence was maximized which led to rapid convective initiation of new storms along the western flank of the Ohio outflow.

The developing multicell cluster in Allen county rapidly became severe with numerous reports of nickel to quarter size hail and torrential rain. The eastern portion of this line represents the mature (severe) stage of this multicell cluster over the city of Fort Wayne while the new embryonic thunderstorm development over northeast Whitley county later becomes the next mature (severe) storm.
