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. 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. ..Lyons/Smith.. 06/10/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...ILN...LMK...IWX...IND...ILX...
