Warmer temperatures will push back into the region over the weekend with highs both Saturday and Sunday in the lower 90s.  The humidity levels will also remain high, which will drive the heat index values this weekend into the mid 90s.  Each afternoon a stray shower or thunderstorm is possible, but much of the weekend will be dry.  Temperatures will remain in the lower 90s on Monday and then will drop back into the lower 80s by Tuesday as a cold front pushes through.
