Concerning...Severe Thunderstorm Watch 485...
Valid 292130Z - 292300Z
The severe weather threat for Severe Thunderstorm Watch 485
continues.
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.
