   The severe weather threat for Severe Thunderstorm Watch 485

   SUMMARY...A threat for damaging wind gusts from 55-70 mph will
   remain probable with a small bowing cluster moving east-southeast
   towards the central Ohio Valley.

   DISCUSSION...A small bowing cluster was ongoing between the I-70 and
   I-74 corridors in the eastern IN. The Indianapolis VWP in the wake
   of this cluster continues to sample a belt of 35-50 kt mid-level
   westerlies which will aid in sustaining convective organization as
   this cluster likely tracks east-southeastward over the next few
   hours. Incipient Cb development is also occurring farther south
   closer to the OH River in southeast IN. It is plausible this may
   merge into the cluster across the IN/OH/KY border area and yield an
   overall southeast shift to convective development. This should
   spread across the I-75/I-71 corridors in southwest OH to northern
   KY. The greatest threat for damaging winds should be focused near
   the apex of the small bow.
