Today will be as hot as yesterday across the Ozarks. I see most areas reaching into the middle nineties. On Monday, Springfield reached 94°.
Of course, it’s the humidity which is making things worse. The combination of heat and humidity will cause Heat Index (HI) values to reach to 100-105° today commonly. A few areas will see the HI climb close to 110° by late afternoon.
An excessive heat warning was issued by the National Weather Service for all of southwest Missouri today.
A cool front will start to change things on Wednesday. This front will shave temperatures back a tad starting on Wednesday and will also spark a few showers or thunderstorms in the Ozarks. Overall, the threat of rain is not very high in connection with this front.
After the front passes, temperatures will be cooler for the rest of the week with highs staying in the upper eighties and lows finally dropping below seventy.
