PHILADELPHIA - The National Weather Services has issued a preemptive Flash Flood Watch for all of southeastern Pennsylvania, part of the Lehigh Valley, and northern New Jersey from Thursday afternoon until Friday morning.
Forecasters say heavy downpours in eastern Pennsylvania could cause localized flooding of creeks and streams and ponding in areas of poor drainage. The weather service predicts that rainfall totals could be between 1-2 inches in southeastern Pennsylvania and up to 4 inches in the Lehigh Valley.
While severe weather is not the main area of concern associated with Thursday nights storms, the weather service says there is a small chance of some severe thunderstorms with damaging straight-line winds and isolated tornadoes.
Leftover showers will move offshore on Friday ahead of a gorgeous weekend with highs in the mid-70s.

THURSDAY: Clouds, showers. High: 76, Low: 62
FRIDAY: Am shower, p.m. sun. High: 73, Low: 60
