Madison, Wisconsin — Much of Wisconsin is bracing for a prolonged stretch of dangerous heat as forecasters warn that temperatures and humidity could combine to produce heat index values as high as 110 degrees this week.
The National Weather Service has issued an Extreme Heat Warning for large portions of the state, cautioning that the prolonged heat could create life-threatening conditions through the workweek and continue into the July 4 holiday weekend.
Officials are urging residents to limit outdoor activities, stay hydrated, and check on vulnerable family members and neighbors as the Midwest experiences one of its most intense heat waves of the summer.
Extreme Heat Warning Covers Much of Wisconsin
According to the National Weather Service, southeastern Wisconsin is expected to experience heat index values ranging from 95 to 110 degrees each day from Monday through Friday.
Forecasters also warned that overnight conditions will provide little relief, with nighttime heat index values remaining in the upper 70s, increasing the risk of heat-related illnesses.
Dangerous conditions are expected to affect communities across much of the state, making it difficult for people without adequate cooling to recover from daytime heat.
Officials continue encouraging residents to stay in air-conditioned buildings whenever possible and avoid prolonged exposure during the hottest parts of the day.
Multiple Wisconsin Cities Could See Dangerous Heat
The prolonged heat wave is expected to impact numerous communities across southern and eastern Wisconsin.
Cities expected to experience the most dangerous conditions include:
- Madison
- Milwaukee
- Kenosha
- Janesville
- Wisconsin Dells
- Fond du Lac
- Beaver Dam
- West Bend
Forecasters said Monday and Tuesday are expected to be the hottest days, although temperatures are likely to remain well above normal throughout the week.
While additional clouds and scattered thunderstorms may develop later in the week, heat index values could still remain in the upper 90s.
Communities near Lake Michigan are also expected to experience unusually warm conditions with little cooling influence from the lake.
Officials Warn Heat Can Be Deadly
Meteorologists and health officials are emphasizing that extreme heat remains one of the nation’s deadliest weather hazards. Meteorologists warned residents not to underestimate the risks.
“The heat is a silent killer. It’s one of the top weather-related killers in our country, and it certainly tops the list here in the Badger State.”
To help residents stay safe, the Milwaukee Health Department has published a list of cooling centers where people can escape the dangerous temperatures.
Officials also recommend drinking plenty of water, wearing lightweight clothing, avoiding strenuous outdoor activities during peak afternoon hours, and never leaving children or pets inside parked vehicles.
Historic Heat Wave Expands Across the Midwest and East
Wisconsin is part of a much larger weather pattern affecting much of the eastern United States.
The National Weather Service has described the event as a “significant, dangerous, and record-breaking heat wave” that could bring some locations close to all-time temperature records.
Forecasters say a strong high-pressure system is expected to remain in place over the eastern half of the country for several days, trapping hot air across the region.
Although scattered thunderstorms may develop later in the week across portions of the Upper Midwest and Great Lakes, forecasters caution that they are unlikely to provide lasting relief from the dangerous heat.
Residents Urged to Stay Weather Aware
Emergency officials continue urging residents to monitor local forecasts and take heat warnings seriously as temperatures remain dangerously high.
People without access to air conditioning are encouraged to visit public cooling centers or other air-conditioned locations during the hottest parts of the day.
With the heat expected to persist through the Independence Day holiday, officials say preparation and caution will be essential to reducing the risk of heat-related emergencies across Wisconsin.
