PHILADELPHIA (WPVI) -- Smoky conditions gradually improve Saturday as we turn our attention to the threat for flash flooding and severe storms.

TONIGHT: Smoky conditions persist as a thicker plume of smoke moves back over the area lingering into early Saturday.

SATURDAY: A warm front lifts north through the region during the morning. Tropical air moves back in with dewpoints climbing well into the 70s.

A few scattered downpours and storms will be around during the morning. The best chance for this activity looks to be near the Pennsylvania Turnpike and areas north.

After lunchtime we'll be watching for the development of scattered thunderstorms.

The Storm Prediction Center has our entire area in an enhanced risk for severe storms. This is level 3/5 on the severe weather scale and means numerous severe thunderstorms are likely.

Storms will be capable of producing damaging wind gusts over 60mph. There's also the threat for flash flooding. A flood watch goes into effect starting Saturday morning and continues into early Sunday. Rainfall rates of 2-3" per hour can't be ruled out. We also have an elevated tornado risk. Have a way to get weather alerts, especially if you have outdoor plans.

SUNDAY: Sunny and more comfortable, high 85.

MONDAY: Mostly sunny and seasonable with lower humidity, high 86.

TUESDAY: Very muggy with scattered thunderstorms around, high 86.

WEDNESDAY: A storm early in the day. Otherwise, we'll be turning less humid, high 86.

THURSDAY: Bright and comfortable, high 83.

FRIDAY: Mostly sunny, high 84.
