Sunny, dry Tuesday in Philly, but rain chances increase later this week

PHILADELPHIA (CBS) -- After a lovely, sunny Monday to cap Labor Day weekend, the pleasant weather continues Tuesday as you head back to work or get ready for back to school.

We start off with a morning chill, and you'll probably want a light jacket or sweatshirt for yourself if you're heading out early for a workout — or for the kids on the way to school.

The next few mornings are the same story, with overnight lows in the 50s before sunshine warms us up.

Sunshine will be in full effect for our Tuesday, which will help warm temperatures back into the mid-upper 70s in the afternoon. Wednesday will feature another cool and crisp morning with a sunny and mild afternoon.

A little more warmth begins to return through the second half of the week, but temperatures will still be near or slightly cooler than normal with highs in the low 80s by Wednesday into Thursday. Not a drop of rain is expected for the majority of the week.

Rain looks to stay out of the forecast through Thursday, but clouds will be on the increase for Friday.

Friday late afternoon to evening is when our next system moves in. An approaching low pressure from the Mid-Atlantic will meet up with a cold front from the west.

This brings us a decent chance of rain from Friday evening through Sunday, with clearing skies expected behind the system by the beginning of next week.
