Delaware is in store for a heat wave, thunderstorms over holiday weekend. What to expect

Fourth of July weekend is finally here, but before you continue celebrating, make note of the intense weather Delaware will experience in the next few days and plan accordingly.

The National Weather Service warns the public about a “dangerous heatwave” across the western United States and hazardous heat in the Southeast and Mid-Atlantic.

The National Weather Service cautions the Mid-Atlantic region about intense heat present in the area on July 5 and July 6.

Above-average temperatures in the mid- to upper 90s are expected in the region, with warm overnight conditions offering little relief. The weather service emphasizes that this can lead to a dangerous situation for those without access to adequate cooling.

Along with the heat, thunderstorm chances are present for the Mid-Atlantic.
