Very hot today, 95 degrees. We looked forward all day to the cold front that would bring us rain and cooler temperatures. When the front arrived at about 2:30 PM, we ended up with thunderstorms and hail. Fortunately most of the hail was pea size with a few marble size so no damage to the aircraft or the roofs. The real treat was a temperature drop from 95 to 67.  A few hours later it was back to 80 degrees.
