LINCOLN, Illinois — This weekend is not the time to be caught outside without a plan.
Central Illinois is heading into a dangerous stretch of heat and storms that forecasters say could push heat index values well above 100 degrees for several days in a row.
Thursday brings the first wave of dangerous heat
Temperatures Thursday are expected to climb between 80 and 90 degrees — but what it actually feels like outside will be far worse.
The National Weather Service is forecasting afternoon heat index values of around 106 in Quincy, 109 in Pittsfield, and as high as 112 near Edwardsville.
Springfield could feel like 100 degrees. Litchfield may reach close to 105.
On top of the heat, there is a 40 to 60 percent chance of thunderstorms Thursday afternoon, with some storms potentially turning strong to severe.
Friday stays dangerous before Saturday peaks
Friday brings highs between 85 and 95 degrees with heat index values ranging from 95 to 105.
Overnight lows will only drop to between 70 and 75 degrees — meaning there will be little relief even after the sun goes down.
A 30 percent storm chance remains in the forecast.
Saturday is the most dangerous day of the weekend
Saturday is shaping up to be the peak of this heat event.
Actual air temperatures are expected to reach into the 90s, with heat index values forecast between 105 and 110 degrees across much of the area.
Thunderstorms remain possible Saturday as well, which means residents could be dealing with both extreme heat and severe weather on the same day.
Sunday offers little relief
The heat does not break heading into Sunday.
Highs will again range from 85 to 95 degrees, with heat index values between 95 and 105 and another 30 percent chance of storms.
What you should do right now
If you are working outdoors or have plans outside this weekend, take this seriously.
Drink water consistently throughout the day — do not wait until you feel thirsty. Limit strenuous activity during peak afternoon hours between noon and 4 p.m. Know where your nearest cooling center is in case your home loses power or becomes too hot.
If thunderstorms move into your area, get inside immediately and stay away from windows.
Forecasts may shift as the weekend gets closer, so keep checking updated information from the National Weather Service.
