Tornado in November?

OK, so why do tornadoes have to happen when I'm on a roll? About 4 o'clock this afternoon, I had 2 of the 3 kids napping, and I'm cranking out fundraiser packets when I get a call from my almost frantic hubby telling me there's a huge storm on the way, and we are under a tornado warning. Yes, that is right, a tornado warning on November 14th. It shouldn't really be that shocking since it was almost 70 degrees today, and we live in Indiana. Since we have no basement or any rooms without windows in our house, I stop what I'm doing, wake up the girls and load up the family and head over to my grandma's. It turned out to be nothing, but you never know. So, the storm passed, we ended up eating supper and then I rush off to a meeting, making it home after 9:30 to a house that was left as it was this afternoon - dishes on the counter, toys all over the floor, fundraiser packets strewn across the dining room table, laundry in the washer and dryer. Good thing I have nothing to do tomorrow.
