Wow, prayers up for this in effected area. Two inch hail will break stuff for sure.
I just came in from taking the clothes off of the line here in SE Ohio and I can smell rain coming. Hoping that the hail goes the other direction!
Heading right for Notre Dame!
We’re a little north of the current watch area. The air doesn’t have that severe weather feel, but certainly the area from Lafayette to St. Louis looks in some trouble...

I just checked the radar in motion, and you’re right. The biggest wad has South Bend in its sights. Luckily we’re a little east of that path (about 40 miles)...

Is it going in the direction?
Is Indianapolis affected?
The warning lasts until 2 AM anyway ~ plenty of time for some Wrath of God action.
