Long Duration Severe Weather Event Unfolds Across the Region - June 13, 2017

Weather.gov > Sioux Falls, SD > Long Duration Severe Weather Event Unfolds Across the Region - June 13, 2017

Overview

A very warm and humid airmass developed across the region during the late afternoon hours of Tuesday, June 13. A cold front moving through the Plains ahead of a very large upper level disturbance was the driving force for scattered thunderstorm development over the Missouri River valley region of central South Dakota and north central Nebraska.

Supercell thunderstorms, some of which would routinely split into two storms, quickly developed producing large hail, damaging winds, and a few very weak tornadoes/gustnadoes. These scattered storms quickly merged into a linear band of storms as they move eastward through South Dakota. As they reached the Interstate 29 corridor, rapid intensification once again took place, producing a large area of high winds as high as 60 and 70 mph as the storms moved through western Minnesota and northwest Iowa before finally weakening below severe limits.
