Weather Authority: Overnight showers lead to cool, cloudy Tuesday

PHILADELPHIA - Tuesday will not be as warm and sunny as Monday as cool temperatures and clouds make their way through the Delaware Valley. 

The morning's rain is due to a low-pressure system moving in from the south and a high-pressure system to the north bringing in air off the ocean, according to FOX 29's Sue Serio. 

As a result, it will be cloudy even when it is not raining. 

Temperatures are expected to be in the 60s with a chance to hit 70 degrees in some parts of the Delaware Valley. 

Looking ahead, the next significant chance of rain is Friday and there's a low chance of rain for Saturday and Sunday.
