The National Weather Service says there was a brief touchdown of an “EF-U” tornado on Sunday in St. Joseph County.
The touchdown was what is called a “landspout,” and it made contact with the ground on Sunday. It touched down briefly in an open field near New Carlisle. A spotter reported that it stayed in almost the same spot and picked up dirt.
The National Weather Service declared it an EF-U tornado since no damage occurred and there was no maximum speed or width measured.

A Landspout Tornado is a weather pattern not associated with rotation from a parent thunderstorm. They are similar to waterspouts, very difficult to forecast and detect, and are also usually much weaker than the more typical supercell-related tornadoes.
