Overview

An upper level low pressure system was in place across the state of Iowa Wednesday, May 29th, 2019. A surface boundary was stretched across Iowa from northwest to southeast across the state from near Storm Lake southeastward into southeast Iowa. This boundary provided the focus for thunderstorm development throughout the late afternoon and evening hours. The low levels environment provided the needed conditions for many of these storms to rotate and produce funnel clouds and brief, weak tornadoes. Many of the tornadoes that occurred were brief touchdowns in open ares with no damage. Two of the tornadoes caused damage, one in Poweshiek County and one south of Iowa Falls near Owasa.
