Scattered afternoon storms are scheduled to develop. These slow-moving storms could lead to localized flooding.

A Flood Warning has been extended through 5 p.m. for the Brandywine Creek at Chadds Ford.

On Tuesday, at least two dozen water rescues were made in Chester County after a powerful storm caused flash floods around the region.

The unstable pattern continues through Thursday when a cold front will finally progress south through the region, bringing some relief from the heat and humidity.

Temperatures also cool off drastically by the end of the week, as winds shift from the east, keeping clouds and cooler temperatures around. By Friday, we drop back into the upper 60s low 70s with a gradual warmup through the weekend.
