It will be a mild start to the weekend.  As skies clear overnight, low temperatures will fall into the upper 50s and lower 60s.  From that mild start, another heat wave begins.  High temperatures will be in the upper 80s and lower 90s on Saturday and in the middle 90s on Sunday.  100 degrees is in the forecast for Monday and the rest of next week will be hot and humid and in the 90s.  Scattered storm chances return Tuesday-Thursday.
