Heat wave brings ‘favorable’ odds that new high temperature records will be set
Cooling centers open to provide relief from the heat

The National Weather Service is warning of “dangerously hot conditions” to start this week, prompting emergency management agencies to open cooling centers and some schools to dismiss classes early.
Forecasts show the heat will dissipate by the weekend, when temperatures will return to normal for late August.
The National Weather Service issued an excessive heat warning through 8 p.m. Monday, warning that heat index values could top out at 115 degrees. Tuesday will bring an excessive heat watch, with “dangerously hot conditions” and heat index values between 100 and 115.
Cory Martin, a meteorologist with the National Weather Service said the heat will start to “fade out gradually“ around Wednesday, bringing temperatures back down to typical values. Martin said at this time of the year daily high temperatures are usually around 80 degrees.
“Today we’re looking at widespread 90s to 100 degrees,” Martin said of the air temperature on Monday.
Record temperatures may be set this week
Justin Schultz, lead meteorologist with the National Weather Service’s Quad Cities bureau, said Monday the odds are “favorable” that standing high temperature records in parts of Eastern Iowa will be broken this week.
The record high temperature in Cedar Rapids on Aug. 26 is 97 degrees, set in 1924. The record high for Aug. 27 also is 97, set in 1995. The National Weather Service was predicting a high temperature of 97 degrees on Monday, and 94 degrees on Tuesday.
How many days have been above 90 in Iowa this year?
The Quad Cities typically sees 10-18 days of 90-plus degree weather each year, said TJ Gunkel, a meteorologist with the Weather Forecast Office in Davenport.
Gunkel said so far in 2024, there have been about 10 days when the temperature has reached 90 degrees or higher in Cedar Rapids. He called it “quite close to climatology.”
How to stay safe, save energy
Schutlz said the key to staying safe during the heat wave is to limit time outdoors when possible, wear loose-fitting clothing and drink fluids to stay hydrated, even if you’re not thirsty.
“We also tell people to check on their neighbors, especially if you have elderly neighbors that may not handle the heat as well,” Schultz said. “Make sure that everybody's OK.”
Alliant Energy spokesperson Morgan Hawk said the company advises customers to save energy by setting the thermostat “as high as possible” while still keeping the space comfortable. Customers also can save energy by closing shades, using ceiling fans, unplugging unused electronics, limiting TV use as background noise, changing out the air conditioner’s filter to improve air quality, and sealing windows and doors to keep cool air inside.
Hawk said Alliant has sufficient resources available to deliver energy to customers, even during extreme heat.
“We design, engineer and construct our facilities to address weather conditions,” Hawk said. “Our crews are prepared to respond to any issues that may arise.“
