Omaha = City of the Tornadoes?

Tonight in and around Omaha, NE, there have been numerous tornadoes in one of the largest storms I've ever witnessed. The IPF seminarians were just about to begin a holy hour when the sirens went off the first of three times. We had a storm drop about 2-3" of rain over the Omaha metro area, and there were reported deaths and injuries as a result of this storm. Below is a picture of the storm just a little while after the bulk of it passed through Omaha:

Since I've come here, there's been a storm (major or minor) about once every other day! I'm surprised, and apparently native Omaha residents are, too, to have such activity during the month of June.
