Expect another hot day, with temperatures soaring up near 100 degrees - the heat index had already risen to 106 by 3 p.m.
But temperatures will take a plunge overnight as a cold front arrives, bringing showers and thunderstorms and temperatures in the 70s by Tuesday afternoon, said Jennifer Schack, 6News meteorologist.

"It's going to be a hot afternoon today and a wet afternoon on Tuesday," Schack said.
At 3:15 p.m., the temperature at Lawrence Municipal Airport was 99, with a 39 percent humidity making the heat index 106 degrees. Winds were from the south at 22 mph and skies were mostly clear.
Schack said there is a frontal system to the north of the Lawrence area in Nebraska. But she doesn't expect it to reach far enough south to create any thunderstorms today in the Lawrence area. The National Weather Service says there is a 20 percent chance of showers and thunderstorms after 1 p.m.
Schack said Lawrence is more likely to get showers, thunderstorms and cooler temperatures on Tuesday. At midnight tonight, the temperature will drop to 82, then begin falling more as the cold front arrives, she said. She said the cold front will arrive about 7 a.m. Tuesday.
Overnight, there's a 50 percent chance for showers and thunderstorms, according to the National Weather Service.
Schack said cloudy skies and scattered thunderstorms are expected Tuesday. By 5 p.m. Tuesday, the temperature will have fallen to 76 degrees, with north winds 8 to 15 mph.
Temperatures will continue to fall and reach a low of 60 by early Wednesday morning. Wednesday's high will be 83, with decreasing clouds, she said.
