Random weather...

So Andy and I went to Malley's Chocolate to at least take advantage of the $.99 hot fudge sundaes at least one time during the promotion (which btw runs until the 31st of this month!)... and it was snowing and hailing tonight. As soon as we got inside the door there was a loud thunder. How strange! Thunder with snow?? I was very confused at the thought of it and so was everyone else in Malley's. Anyone ever heard of thunder with snow or hail instead of rain?
