Flood — Jul 15, 2020

Moderate to heavy rain moved into the area causing some isolated minor flooding in Andrew and Macon Counties. Some isolated road closures resulted, but no damage was reported with this flooding.

Flood — Jun 9, 2020

A brief tornado formed near I-29 close to the town of Oregon, Missouri. This tornado was filmed, so while video evidence exists, there was no reported damage from this brief tornado. Ongoing moderate to heavy rain caused some roads to be closed in central Missouri through most of the day.

Widespread severe weather moved through the region on May 28. One supercell produced several tornadoes, including the Lawrence to Linwood, Kansas tornado. This storm then went on to produce an EF-2 tornado in northeastern Clay County and did damage to portions of Kearney, Missouri. Earlier in the day, through the morning and early afternoon hours several storms moved through northern Missouri c...
