 An excessive heat warning is in effect until 8 o'clock this evening. The high today soaring to 100. The heat index around 111 adding to humidity. As temperatures climb, there will be a slight chance for a shower or thunderstorm, otherwise a mix of clouds and sunshine. And then overnight, a cloudy sky with light winds and a low down to 77. Another hot day tomorrow with sunshine, but the humidity level should be a little bit lower with winds out of the north and a high of 96. Then an occasional afternoon shower or thunderstorm popping up for Monday with a high near 94 degrees. I'm Jeff Marr from the Weather Channel for Talk Radio 680 WCBN.
