Philadelphia weather: Rounds of rain, storms expected throughout the week

Weather Authority: Monday night forecast

FOX 29's Kathy Orr breaks down the rainy weather and lingering humidity to come this week.

PHILADELPHIA - A muggy Monday with afternoon and evening showers will set the tone for a pattern of unsettled weather that forecasters believe will clear up by the weekend.

FOX 29's Kathy Orr expects more humidity and more showers to continue in the area this week with temps in the 80s that will feel much warmer and uncomfortable.

A flash flood warning was issued in Southern Delaware until 12:45 a.m. Tuesday along with a tornado warning for Sussex County, including Dewey and Rehoboth Beach.

Showers will move into the parts of Pennsylvania and New Jersey overnight into Tuesday, with a relatively rain-free day.

Forecasters expect dense cloud cover to continue on Tuesday, but showers will be much more isolated and return by early Wednesday morning.

The rainy weather pattern is ahead for Thursday with lingering humidity.

Forecasters expect the gloomy spell to end on Friday when the sun reemerges and stays out for the weekend.

Due to the storms, Philadelphia International Airport announced departing and arriving flights are experiencing delays. Flights heading to PHL were placed in a ground stop Monday afternoon. Travelers are urged to check with their airlines for the latest flight updates.
