The heat and humidity will continue to build over the weekend with temperatures expected to climb into the mid and upper 80s.  The humidity levels will also be on the rise and by Sunday afternoon dewpoints will rise well into the mid 60s.  This will result in a heat index into the lower 90s.  Other than a stray thunderstorm on Saturday, it's looking like a dry first half of the weekend.  A better chance for afternoon thunderstorms will develop on Sunday.
