Hail
A few minutes ago I heard the longest burst of Thunder I've ever heard before. It must have lasted 60 seconds - which is a long time for thunder. Then a few minutes after the thunder my little dogs goes tearing down the hallway barking and growling, and ran back. I thought he was afraid of the washer (which was in the spin cycle) so I took him to the garage to show him what the noise was. But no, it started to hail. It hailed for only 3 minutes or so, but the hail was just about as large as marbles. I know hail can get big, in Texas, but we always have small hail here. Skippyjon didn't seem to know whether to be afraid or to attack the weather!
