Expect the radar to be much quieter today compared to yesterday. A stray shower is possible, but anything today will be brief and isolated (10%). The bigger story will be the thick humidity. Heat index values will approach 100° this afternoon. Skies will start off cloudy and we’ll end with partly cloudy conditions.
