Sunshine will fade behind increasing clouds Saturday, but temperatures will remain unseasonably warm.  Our 5 Degree Guarantee is 88.  While a stray shower can't be ruled out, most will remain dry.  Thunderstorms will become more likely on Sunday as a cold front drops through the region.  We're expecting highs on Sunday in the lower 80s with high humidity.  Isolated thunderstorms are possible on Memorial Day with temperatures remaining in the 80s.
