Norman, OK – Millions across the Midwest and Great Lakes should prepare for multiple rounds of severe thunderstorms Wednesday, with forecasters warning that damaging winds up to 80 mph could accompany the strongest storms.
According to the National Weather Service’s Storm Prediction Center (SPC), an active weather pattern is expected to produce several rounds of severe storms across portions of Nebraska, Iowa, South Dakota, Minnesota, Wisconsin, northern Illinois, northern Indiana, Michigan, and surrounding states throughout Wednesday, July 1.
The greatest concern is widespread damaging straight-line winds, with some storms capable of producing gusts up to 80 mph. Those winds could down trees and power lines, damage buildings, and lead to scattered power outages.
The SPC also warns that all severe weather hazards are possible, including:
- Damaging wind gusts up to 80 mph
- Large hail
- Isolated tornadoes
- Frequent lightning and torrential rainfall
A broad Enhanced Risk (Level 3 of 5) covers much of southern Minnesota, central and eastern Wisconsin, and parts of Michigan’s Upper Peninsula, while surrounding areas remain under a Slight Risk (Level 2 of 5) for severe weather.
Forecasters cautioned that the exact timing and development of each round of storms remains uncertain. However, confidence is high that several areas across the Midwest and Great Lakes will experience severe thunderstorms at some point during the day.
Residents are encouraged to monitor the latest forecasts, enable Wireless Emergency Alerts, and have multiple ways to receive weather warnings. Those with outdoor plans should be prepared to seek sturdy shelter quickly if severe thunderstorm or tornado warnings are issued.
The SPC said forecast details, including the timing and location of the strongest storms, may continue to evolve as Wednesday approaches.
