Hot at blazes this weekend. The National Weather Service has issued an Excessive Heat Warning for all of Cape May County from Noon on Saturday through Sunday at 9:00pm. Temperatures will easily climb into the mid to upper 90s on the mainland, and in the low 90s at the beaches. The heat index is expected to hit about 110 degrees with the chance of a thunderstorm in the evening. A front will move into our area on Monday or Tuesday which should break the oppressive humidity.
