Hail in Champaign-Urbana

Here is a shot of the hail dents on our hailpad at the Illinois State Water Survey in Champaign from this morning’s storm. Most of the dents where in the 1/4 to 1/2 inch range.

To construct a hailpad, we use sections of flourist or floral foam covered with aluminum foil. It is low tech but an excellent way to record hail sizes and density, especially when no one is around.
