NWS Storm Prediction Center has 36 preliminary tornado reports for March 6, 2017 from Kansas, Iowa, Missouri and Illinois. Most of them occurred in Missouri where 18 injuries were reported in Jackson and St. Charles counties. A confirmed tornado touched down near Princeton and Zimmerman, Minnesota, damaging homes and downing trees. It was the earliest tornado in the history of the state. The outbreak comes less than a week after deadly tornadoes struck the Midwest.
The storms unleashed damaging winds, heavy rain, large hail and isolated tornadoes but there were no reports of casualties this time. Powerful winds extended as far south as the Ozark Mountains in Arkansas, where a post office and church were damaged, and as far north as Minnesota where NWS confirmed the earliest tornado in the history of the state.
Wind damage was reported across much of Missouri, where most of the tornadoes occurred. Baseball-sized hail was also reported in parts of the state.
At least 15 people have been injured after a tornado moved through Oak Grove, MO on Monday night. Officials said 483 homes there sustained some type of damage, along with 10 to 12 commercial buildings.
"It looks like the injuries are minimal so, based on some of the damage I've seen, it's rather amazing," Oak Grove Mayor Jeremy Martin said in a Tuesday morning press conference.

A powerful wave of thunderstorms and hurricane-force winds swept through Iowa, spawning several tornadoes, damaging buildings and knocking out electricity. There had been no reports of injuries, NWS said.
