Springfield, IL – Residents across central Illinois are facing sweltering conditions today, with heat indices climbing near 100 degrees, according to the National Weather Service. Forecasters warn the unseasonably warm stretch will dominate the region through mid-week before a slight cool-down arrives.
According to the National Weather Service Central Illinois office, temperatures Sunday are expected to reach between 90 and 97 degrees, with the most intense heat occurring in the afternoon hours. While an isolated storm cannot be ruled out in west-central Illinois today, dry and hot conditions will remain the main story through Wednesday.
Highs Monday through Wednesday are forecast in the low-to-mid 90s, with little overnight relief. Forecasters say the warm pattern will persist until Thursday, when temperatures are expected to dip slightly into the mid-to-upper 80s. Thursday also carries a 30 percent chance of showers and thunderstorms, offering the first significant break in the heat.
Meteorologists emphasize that while September typically brings more moderate conditions, this week’s forecast marks a continuation of unusually warm air across the region. Residents are advised to limit outdoor activity during the hottest parts of the day, stay hydrated, and check on vulnerable neighbors and pets.
This extended heat comes at a time when many are heading outdoors for fall harvest activities and local events, raising concerns for both workers and families spending long hours outside.
