 The heat index, 102 to 105 today. Low tonight, 74. Tomorrow and Thursday, random storms back on the radar. Perhaps 30% coverage, 30 to 40 tomorrow. And maybe a little better, maybe closer to 50% coverage on Thursday. Still, no guarantee your town's going to get wet. Many towns will get skipped. 99 tomorrow, 96 Thursday. More blazing heat Friday and Saturday with perhaps the highest heat indices of the year by then.
