Extreme heat fueling severe weather across Plains and Midwest

weather map


High heat and moisture are fueling storms for parts of the country that turn severe and create dangerous conditions for businesses along their path.

Key Highlights

Threats: Damaging winds, hail, heavy downpours

States affected: MO, AR, NE, KS, KY, IA, WI, IN, IL, PA, WV

When: Tuesday, June 21- Wednesday, June 22

Severe Weather Threat

On Tuesday, the threat of severe storms will stretch from Kansas to Wisconsin. High heat and moisture will provide an abundance of fuel for any storms that develop to turn severe. Cities such as Omaha, Nebraska; Des Moines, Iowa; and Madison, Wisconsin; could be dodging storms Tuesday afternoon or Tuesday evening. The Chicago region currently looks to be outside of the main risk area but is not entirely out of the question that a storm will make it to the city Tuesday night. If this occurs, the highest chance for storms would be in the northern and western suburbs.

While Tuesday's storms may be isolated, the extreme heat in the Plains and Midwest will heighten the severity of storms that do develop. With increasingly humid conditions and high temperatures in the 90s for most of the threat area, those without power and air conditioning in the wake of a severe storm may experience uncomfortable or even dangerous conditions.

Storms will continue to march southeastward Wednesday, stretching across much of the Ohio Valley. While the severe risk may be isolated like what is expected Tuesday, showers and storms will still be possible in places such as Louisville, Kentucky; Charleston, West Virginia; and Pittsburgh. Similar to Tuesday, hot conditions will make any power outages more impactful than normal.

Businesses in the area need to keep a close eye on this system and should:

  • Prepare for operation interruptions due to extended power outages 
  • Expect ground logistics disruption due to road closures and downed trees.
  • Ensure all employees and visitors on-site have a way to be notified of severe weather
