While starting nice, the Fourth of July weekend will end on a rough note around Chicago due to powerful thunderstorms.

A surge of warmth and humidity on Sunday is setting the stage for strong thunderstorms to erupt as the holiday weekend comes to a close.

"The biggest threat for severe weather appears to be after dinnertime and into the first part of Sunday night with a line of thunderstorms approaching from the northwest," stated AccuWeather.com Meteorologist Bill Deger.

"Strong, damaging winds will be the greatest threat faced from the thunderstorms, along with hail and flooding downpours," Deger continued.

An isolated tornado cannot be ruled out.

The thunderstorms will depart by Monday, but heat and humidity will remain with temperatures soaring to the upper 80s.

Another line of thunderstorms will cross Chicagoland on Monday night. However, all the ingredients for severe thunderstorms are likely not to be present.

Residents should still prepare for downpours to slow down travel and frequent lightning.

While another shower or thunderstorm will linger through Tuesday, lowering humidity in the afternoon will be a sign of nicer days ahead.

Wednesday and Thursday are shaping up to be great days for outdoor activities with an area of high pressure promoting low humidity, highs near 80 F and partly to mostly sunny conditions.

Baseball fans may be wishing that the city's White Sox and Cubs were not on the road these two days.
