Philadelphia weather: Monday evening forecast

FOX 29 meteorologist Kathy Orr looks at current conditions and breaks down the 7-day forecast. 

A sunny and pleasant start to the week will be interrupted by a round of scattered storms on Tuesday that could turn severe.

Severe weather threat increases Tuesday with multiple rounds of storms 

What we know:

Forecasters say temperatures will stay mild on Monday with highs expected to remain in the low 80s with plenty of sunshine. 

A round of weekend rain paired with the favorable conditions on Monday will help the air quality continue to improve.

Scattered to numerous thunderstorms are expected Tuesday, with the potential for damaging winds, tornadoes, flash flooding, and large hail. 

The National Weather Service says multiple rounds of storms could impact the region throughout the day and into the night. 

A Flood Watch is in effect from Tuesday morning through late Tuesday night for parts of northern Delaware, New Jersey, and southeast Pennsylvania. 

The watch includes cities such as Philadelphia, Wilmington, Trenton, Camden, and Norristown. 

The National Weather Service says rainfall rates could reach up to 2 inches per hour at times, increasing the risk for flash flooding in low-lying, flood-prone, and urban areas.

Flooding may occur in poor drainage areas, creeks, streams, and rivers, which could impact travel and property. 

The National Weather Service urges residents to remain alert for changing weather conditions and to seek shelter indoors if thunder is heard. 

Officials recommend having multiple ways to receive weather warnings and to monitor later forecasts in case Flash Flood Warnings are issued. 

The Flood Watch covers a wide area, including New Castle County in Delaware, several counties in New Jersey such as Camden, Mercer, and Monmouth, and Pennsylvania counties including Philadelphia, Chester, Montgomery, and Bucks.

How to stay safe during severe storms and flooding 

The National Weather Service recommends seeking shelter indoors if you hear thunder and having more than one way to receive weather warnings.

Monitoring local forecasts and being ready to act quickly if conditions worsen can help keep you and your family safe. 

If you live in a flood-prone area, consider moving valuables to higher ground and reviewing your emergency plan. 

Avoid driving through flooded roads, as even a small amount of water can be dangerous.
