Strong low pressure moving from southern Minnesota to central Wisconsin pushed a cold front into the Ohio Valley during the late morning and afternoon hours of Leap Day 2012.  Temperatures were 10 to 15 degrees warmer than normal, in the 60s, with moist air flowing northward from the Gulf of Mexico.  Meanwhile, winds aloft were coming in from the west at speeds over 100 mph from southern Missouri to southern Indiana.  The atmosphere became very unstable and storms erupted early in the day.  By the time the event was over, six tornadoes had touched down in central Kentucky.  Click here for an overview map of the entire event and for details of each tornado.

We also received the following photos, from other storms that formed that day (click on an image for a larger version):
