AccuWeather: Frost Advisory and a Freeze Warning overnight

PHILADELPHIA (WPVI) -- We all wake up Friday with either a frost or freeze, then summer heat sets in.

FRIDAY: High pressure will give us a sunny Friday with temperatures rebounding back into the lower 60s. This is still a good 5 degrees or so below average.

SATURDAY: The weekend then starts off with some brief sun before clouds roll in with a warm front. This will keep out temperatures similar to Friday and could introduce a late-day shower for areas northwest of Philadelphia. High of 63.

SUNDAY: That warm front pushes through and temperatures and dewpoints are off to the races. You will feel the increasing humidity in the air as temperatures rise into the upper 70s. It won't be a totally sunny day though as a lot of clouds look to be in the mix.

MONDAY: A taste of summer! Enjoy the warmest day of the year so far under partly sunny skies, high 86. A tad humid too.

TUESDAY: It's another very warm day with sun followed by increasing clouds. A cold front approaches from the west and brings the chance for a late-day thunderstorm, high 85.

WEDNESDAY: Partly sunny and still mild, high 80.
