Late-season Thunderstorms

Apparently, we have some rigorous updrafts out there. We've had some lightning and thunder outside our windows here in Grand Forks, and we even had a 0.75 inch report of hail down in Stutsman County (near Ypsilanti) earlier this afternoon. With freezing heights fairly low that doesn't surprise me.

The abundance of lightning is, however; especially this far north. In my forecast last night, I had thunderstorms as a pType in my grids along the frontal boundary, but scaled things back fairly quickly as the afternoon/evening progressed and the boundary lifted northward. So, that part of the forecast busted!
