 There's some relief on the way from this week's 90-plus degree temperatures, but when it comes to the humidity, it'll stay up with thunderstorms in the mix. A break in temperatures will not get to Delaware until closer to the weekend, but showers and thunderstorms will accompany the lower temperatures in the mid to upper 80s. Delaware National Weather Service lead meteorologist Paul Fitzsimmons explains why the heat and humidity is showing up early this summer.
