Central Illinois, including Champaign and surrounding areas, is experiencing intense heat this week. Temperatures are rising into the mid-90s, with heat index values reaching as high as 107°F, making the heat feel even more unbearable. Along with the extreme heat, scattered thunderstorms are expected daily through Thursday, raising concerns about safety and power outages.
Heat Advisory in Effect Across Central Illinois
A Heat Advisory is in effect for Champaign County and much of central Illinois as the region faces dangerously high temperatures. With highs in the mid-90s, the heat indices, which factor in humidity, will be between 100°F and 107°F from Wednesday through Thursday.
The combination of hot temperatures and high humidity can lead to heat-related illnesses, especially for those who work outside or lack air conditioning.
Thunderstorms to Provide Temporary Relief
Although the heat will remain intense, there is a chance for scattered thunderstorms to form each afternoon and evening. These storms will have a coverage of 30% to 50%, meaning they may not affect every area but could bring brief rain and cooler air. The storms, however, could also cause local flooding, particularly in low-lying areas, and disrupt power supply due to brief outages.
Safety Tips for Dealing with the Heat
Residents in Champaign, Urbana, Mahomet, and other nearby towns are urged to limit outdoor activities between noon and 6 p.m., the hottest parts of the day. It’s important to stay hydrated, wear light clothing, and avoid strenuous outdoor work.
If possible, stay inside and use air conditioning. For those who don’t have air conditioning, it’s vital to find cooler places such as shopping malls or public buildings.
Power Demands and Flooding Risks
As temperatures rise, electricity usage will increase, especially with air conditioners running at full capacity. Power outages are possible, particularly during thunderstorms. Additionally, heavy rain from the storms could cause localized flooding, especially in low-lying streets and areas prone to water accumulation.
