Watch NBC 4 free wherever you are WATCH HERE WATCH HEREThe temperature, combined with the high dew points, will result in heat indices near 100 degrees both Thursday and Friday. Expect the heat index to peak in the mid to upper 90s through Tuesday. Along with the heat, expect a few showers and storms to bubble up during the afternoon and evening hours. In addition, some of the storms could produce heavy downpours, so there is a low risk of flash flooding, too.
