Storms on Thursday afternoon and evening could be more robust than previous days, with a greater concentration of strong wind gusts from northern Virginia to southwestern Massachusetts, according to AccuWeather.

Thursday's storms may contain damaging wind gusts and
spotty hail late this afternoon through late evening, likely between 3 p.m. and 11 p.m., NWS forecasters wrote.

"There is a small risk that thunderstorms become a bit more widespread, in which case damaging wind gusts could be a bit more numerous," the NWS said.

Friday will offer little reprieve from the heat, with temperatures remaining in the mid- to upper 90s and heat index values once again in the triple digits.

More numerous thunderstorms are likely on Friday afternoon and evening. Some of these storms may contain damaging wind gusts or large hail.
