Hail does happen in warmer weather. It is associated with severe thunderstorms. You must be thinking sleet which is colder weather.
I just saw the two inches, and the guy using the snow blower. It didn't seem to be melting!
One summer day, I was speeding down the interstate, when all of the sudden, it was like I was driving on marbles. A recent thunderstorm had just deposited several inches of hail on the road. It was very strange to have an icy road condition on such a hot day.
