The National Weather Service today (July 5) issued a heads-up for excessive heat and humidity and the threat of scattered to numerous thunderstorms in eastern North Carolina beginning Wednesday afternoon and evening.

This will begin an active, several-day period of severe storm possibilities as a very unstable air mass sits over the region with a stalled front in the vicinity.

Damaging winds, large hail, torrential downpours with localized flooding, and frequent lightning are possible with the thunderstorms.

The combination of hot temperatures and very humid conditions will set the stage for potential heat indices reaching 105 degrees or higher on Wednesday, although more inland than on the coast, and possibly through the end of the work week.
