Miami County, IN Tornado

NMDA algorithm performed well on developing and descending mesocyclone that moved eastward out of Darke County and into Miami County, which ended up producing a tornado that destroyed a house. The algorithm indicated medium strength on the meso some 20 minutes before the tornado struck the area NW of Milton, IN. The temporal resolution from time step to time step gave me higher confidence that a strengthening meso was in progress.

Mesocyclone strengthening across SE Darke County eventually produced a tornado in SW Miami County. Values on the NMDA were in the ‘extreme’ range just before the reported tornado.
