Ice pellets!?

I looked at the weather forecast and for Wednesday it says that the best current guess at what will be falling out of the sky is “Ice Pellets.” I saw that and thought that where my Mother lives, in southern Arizona, “Ice Pellets” would be made by a machine, and you might pick up a bag of them at the store if you were going camping or something and wanted to pack some food in an ice chest. Here, “Ice Pellets” fall right out of the sky for us. How convenient!
