A strong storm system lifted northeast into the region from Oklahoma, during the late afternoon and early evening hours on February 28th. The dynamics from this storm system provided the lift for rapid thunderstorm development along and north of a warm front by the early evening hours. There were numerous reports of hail with the storms, as well as some flash flooding.
In addition, two tornadoes were observed. They were associated with a supercell severe thunderstorm, which earlier had produced an EF4 tornado in Linn county Kansas. The first EF1 tornado was observed in Bates county between Amsterdam and Adrian and moved northeast. Damage was to one structure with telephone poles down as well. The second EF1 tornado was near Blairstown in Henry county, over open country.
