6/19/2018 1:05 PM The larger hail has a solid white core. Some of the larger hail was hat shaped, with a smooth bottom and the top consisting of many small bumps or growths the size of bee bees. Very pretty. I was driving south on Federal from Hamden and could see the hail colored clouds. There was also a significant updraft on the leading edge of the cloud (east Side). You could see lower clouds being sucked int the larger cloud. Very interesting.
