Highest Heat Index Value Around 105 degrees This Afternoon…
July-like heat and humidity will continue to dominate the area this afternoon with high temperatures rising into the low to possibly mid 90s. The hot temperatures combined with the high humidity levels will produce heat index values as high as 105 degrees in a few areas this afternoon across central, east central and southeast Illinois.
Heat index values this high increase the risk of developing heat illnesses. Even though the calendar says we are in the middle of September, dress for Summer, drink plenty of fluids and limit time outdoors today. Check on the elderly and pets, as well as those without access to air conditioning.
Heat illness develops quickly and can overtake you with little warning.
