 An excessive heat watch goes into effect Sunday afternoon coming up. First for today, we'll have sunny to partly cloudy skies. An isolated shower chance late in the day with highs in the upper 80s. For tonight, a chance for some showers and storms. We'll drop back to a low of 71. Saturday, any showers and storms ending early in the day, a high of 93. And hot and muggy into the day on Sunday with highs in the upper 90s. I'm weatherology meteorologist Michael Caro on KMA. Currently at 69.
