DETAILED FORECAST:

TONIGHT: Mostly clear skies. Warmer with lows in the lower 70s, according to Storm Center 7 Weather Specialist Nick Dunn.

MONDAY: Partly cloudy skies with highs in the middle 90s. This will be dangerous heat with heat index values near or just over 100.

A few spotty showers or thunderstorms may develop in the afternoon and evening to provide brief relief from the heat. Heavy rain is the main threat from any storms that do develop. Overnight lows will be in the 70s, providing little relief.

TUESDAY: Heat wave continues with highs in the lower to middle 90s. Heat index values as high as 100. A couple pop-up showers or storms possible to provide brief relief from the heat in a few spots. Overnight lows will be in the 70s providing little relief.

WEDNESDAY: Staying hot and a bit muggy with highs in the mid 90s and heat index values may exceed 100 at times. Overnight lows will be in the 70s providing little relief.

THURSDAY: More heat. Partly cloudy with highs in the middle to potentially upper 90s. Heat index values over 100 possible. Overnight lows will be in the 70s providing little relief.

FRIDAY: Continued heat and no sign of relief with highs in the middle 90s. Heat Index values around 100. Overnight lows will be in the 70s providing little relief.

SATURDAY: Remaining hot with lows in the lower 90s. Heat index may fall below 100 here, but overall heat effects will continue due to the long duration of heat so I will maintain a Level 2 here for the time being.

SUNDAY: An isolated shower or thunderstorm may develop. Otherwise, a touch cooler with highs near 90.
