Areas affected...parts of far eastern Illinois and central and
southern Indiana

Concerning...Severe potential...Watch unlikely=20

Valid 100005Z - 100200Z

Probability of Watch Issuance...5 percent

SUMMARY...Scattered strong storms may produce occasional damaging
gusts this evening. Storm organization will be limited and a WW is
unlikely.

DISCUSSION...As of 00 UTC, regional radar data showed a cluster of
stronger thunderstorms near a remnant MCV over parts of the upper
Wabash Valley. The environment is moderately unstable, owing to mid
70s F surface dewpoints. However, vertical shear is not particularly
strong. With bulk shear generally below 25 kt, the observed
cluster/multicell storm mode should continue this evening.=20

Storms will move eastward across central and southern IN toward the
OH/KY border later this evening. Some upscale growth may support a
risk for occasional damaging gusts with water-loaded downdrafts.
However, the lack of broader organization should keep storm
organization and the overall severe risk isolated. These storms
should also begin to weaken with the loss of diurnal heating later
tonight. Thus, while some risk for damaging winds is possible, a WW
is unlikely.
