The heat has calmed down a bit in town, but thunderstorms have revved up Tuesday morning with potentially damaging winds and warnings of floods.

The National Weather Service has issued an urban and small stream flood advisory and severe thunderstorm watch for Evergreen Park and other Cook county towns in northeast Illinois, in effect until 9 a.m. Tuesday, temperatures are expected to reach 86 degrees with a low of 73 in the evening.

At around 6:07 a.m., the NWS's doppler radar saw thunderstorms with heavy rainfall moving toward the area producing rainfall in excess of one inch per 30 to 45 minutes. The severe thunderstorms may produce damaging winds in excess of 60 miles per hour. The NWS says runoff from the rainfall may cause minor flooding, especially near low water crossings and small streams. Officials warn residents:

• Do not attempt to cross bridges, dips or other low spots if water covers the roadway.
• Never try to cross a flowing stream, even a small one, on foot or in a vehicle.
• Move to an interior room on the lowest floor of your home or business.

"There is a small chance for severe storms Wednesday morning in areas of far northern and northeastern Illinois," says the NWS. On Thursday, a chance for severe storms is expected to spread back across the entire area.

Additionally, the temperature will have a high of 98 degrees with heat indices expected to top 105 degrees on Wednesday.
