Several strong thunderstorms have popped up across the northern 2/3 of the Tri-States. The strongest cell is near Macomb, with another cell near Lima and a third cell east of Rushville. While these are diurnally driven by daytime heating, a very cold pool of air aloft at 20,000 FT can enhance stretching of updrafts in these thunderstorms and cold air funnel cloud are not out of the question. If you see one go inside to a safe place until the storm passes, although they rarely touch down. Torrential rainfall can lead to flooding of low lying creeks and streams too.
