MOUNT AYR, Iowa — Despite showers on Monday, a dangerous heat wave continues to bake Ringgold County and southwest Iowa. The excessive temperatures bring triple-digit heat index values, stifling humidity and little overnight relief as state and local officials urge residents to take precautions against heat-related illness.
Large portions of the state remain under Extreme Heat Warnings, with heat index values ranging from 103 to 115 degrees in some areas. Meteorologists say the combination of high temperatures and oppressive humidity has created hazardous conditions that can quickly lead to heat exhaustion or heat stroke.
“This isn’t just typical summer heat,” weather officials have warned. “The prolonged nature of this event, combined with warm nights, means people have fewer opportunities to recover from the heat.”
Overnight temperatures are expected to remain in the upper 70s across much of the state, offering limited relief.
The extreme conditions are being driven by a sprawling high-pressure system, often referred to as a “heat dome,” that has settled over the central United States. The system traps hot air near the surface while suppressing cloud development, allowing temperatures to climb day after day.
In Iowa, the heat has been intensified by high humidity. As cornfields across the state reach peak growing season, moisture released through a natural process known as evapotranspiration — sometimes called “corn sweat” — adds even more humidity to the air, making temperatures feel several degrees hotter than the thermometer indicates.
Emergency management officials across Iowa are encouraging residents to stay hydrated, limit outdoor activity during the hottest parts of the day, wear lightweight clothing, and check on elderly neighbors and others who may be more vulnerable to the heat. They also remind residents never to leave children or pets inside parked vehicles, where temperatures can become life-threatening within minutes.
Ringgold County officials continue to monitor the weather and are at this time not opening any dedicated cooling centers at this time.
“Historically, we have not seen a community need that would warrant them,” Ringgold County Emergency Management Director Melissa Stark said in an email. “We continue to monitor conditions and would reassess if circumstances changed, such as prolonged power outages or other factors affecting residents’ ability to stay cool.
Stark echoes statewide precautions during times of exteme heat.
“We encourage everyone to stay hydrated, limit outdoor activity during the hottest part of the day, and check on elderly neighbors and others who may be more vulnerable to the heat,” Stark said.
The heat is also placing added strain on power systems as air conditioners run continuously across the region. Health experts say those without access to air conditioning should seek out public places with air conditioning during peak afternoon hours where they are available.
In Iowa, according to research from Advance America, over 180,000 low-income households regularly go without AC at night. The report states these households regularly switch off their air conditioning at night to save money, going without cooling for an average of 11 nights per month even as summer temperatures climb.
Forecasters expect the dangerous conditions to continue before scattered thunderstorms and a gradual shift in the weather pattern may bring modest relief to parts of the state. However, any cooling is expected to be temporary, with summertime heat likely to persist into early August.
For now, officials say the message is simple: take the heat seriously.
“Heat is one of the deadliest weather hazards in the United States,” emergency officials note. “Staying hydrated, staying cool, and checking on others can save lives.”
