Heat index values will generally reach the mid to upper 90s, possibly near 100 degrees across Delmarva. Scattered storms will develop through the afternoon Monday, and with the elevated heat, more energy will be available to support the threat for some stronger storms that will be capable of producing damaging winds.

The storm threat increases a little more Tuesday as a cold front approaches and moves through the region. Scattered thunderstorms are expected, and some could become strong to severe thanks to stronger winds. The exact timing of the front remains uncertain, and if the storms arrive a little sooner, the severe threat will not be as great as Monday. 

The storms Tuesday into Wednesday will finally break the prolonged heat. By the second half of next week, temperatures should return to the 80s.
