Tornado of March 31, 2014

Tornado season got off to an early start in 2014 with the first confirmed tornado sighting in St. Leo. A weak tornado was confirmed on Monday March 31. A few farmsteads sustained damage. There were no injuries or fatalities.

The tornado spawned ahead of an intense low pressure centered over extreme southeastern South Dakota.  A strong, narrow line of storms formed quickly over the Minnesota/South Dakota border around the 3 p.m. hour and moved north-northeast.  The tornado itself spawned around the 4 o'clock hour.
