Summary of Severe Weather on June 5-6, 2018

Overview

Like the area saw just a few days ago (June 1, 2018 Summary), the interaction between a warm airmass over South Dakota and a cold front led to the development of severe thunderstorms that moved east across northern South Dakota.

Thunderstorms developed in western South Dakota during the evening hours of June 5th, 2018 and moved into north central SD. These initial thunderstorms produced hail up to 2.5” in diameter and winds of 60-75 mph between Rapid City and the North Dakota border. As the storms continued east into north central SD, it produced hail to the size of golf balls in western Corson County. But the main impact was the severe winds. These winds were supported by environmental conditions that were favorable for strong thunderstorm winds (very warm temperatures along with dry air in the lower and middle levels of the atmosphere).

The core of the strongest winds occurred along and to the south of U.S. Highway 12 from Walworth County east into Minnesota. This led to several outbuildings being partially or totally destroyed, damage to grain bins and silos, broken power poles, and numerous areas with tree damage. The highest reported wind gusts were measured to the east-southeast of Lowry, with measured gusts of 97 and 100 mph.
