AI Summary

The Storm Prediction Center issued Severe Thunderstorm Watch 506 for parts of far southeast Indiana, far northern Kentucky, central and southern Ohio, southwest Pennsylvania, and West Virginia, effective Tuesday afternoon from 1:10 p.m. to 8:00 p.m. EDT. The watch highlights scattered damaging wind gusts up to 70 mph as the primary threat, with the possibility of large hail up to 1.5 inches in diameter and a low probability of one or two brief tornadoes. Thunderstorm activity is expected to increase as a pre‑frontal trough and cold front move through the region, creating strong to severe environmental conditions. The linear convective mode favors damaging gusts, while low‑level shear could support isolated, line‑embedded tornadoes.
