Residents in Mount Pleasant and across Henry County are being urged to prepare for dangerous heat as the National Weather Service has issued an Extreme Heat Watch beginning Sunday afternoon and continuing through Tuesday, with the potential for it to stretch deeper into next week.
Forecasters say heat and humidity will build quickly, with heat index values expected to range from 100 to 110 degrees across southeast Iowa. Nearby forecast points, including Fairfield and Burlington, show heat indices climbing above 100 each day from Sunday through at least Wednesday, meaning Henry County can expect similar oppressive conditions.
High temperatures in the Mount Pleasant area are expected to push into the low to mid-90s, but the humidity will make it feel significantly hotter. Health officials warn heat-related illnesses become much more likely in these conditions, especially for older adults, young children, and those working outdoors.
Residents are encouraged to stay indoors when possible, drink plenty of water, take frequent breaks if outside, and never leave children or pets in vehicles.
Before the heat arrives, the National Weather Service recommends checking air conditioners, stocking up on water, and making plans for possible power outages. Checking in on neighbors, family members, and pets during the hottest part of the week is also encouraged.
There is also a slight chance for isolated strong storms late tonight into early Sunday morning, mainly south of Highway 34. While the severe weather threat has decreased, gusty winds and small hail remain possible.
KILJ will continue to monitor updates from the National Weather Service as the heat wave approaches.
