Cool, mild weather for Saturday

It may be the end of July, but the weather outside has it feeling more like the end of October.
It is unseasonably mild for late July, a time when heat and humidity typically are at a high. But don't expect this to last.
Saturday has a high of 77 degrees and temperatures will gradually increase through Monday.
Starting on Tuesday, temperatures go to the mid- to upper-80s through the rest of the week.
