Philadelphia woke up Monday, July 6, to a cloudy, muggy start with temperatures parked in the low to mid 70s, and the atmosphere is not done with us yet. A Flood Watch remains in effect through 8 p.m. Monday, with additional rounds of showers and thunderstorms expected to fire up by midday and hang around into the evening. Any heavy downpours could trigger urban flash flooding and slow commutes across the metro area.
Afternoon Storms And Flood Risk
Forecasters are calling for a high near 80°F with a northeast breeze around 5 to 10 mph. The odds of showers and thunderstorms climb by midday and stay elevated through the afternoon. Many neighborhoods can expect roughly three quarters of an inch to about an inch of new rain, while localized downpours with rainfall rates over 2 inches per hour remain on the table.
The overall flash flood threat is lower than it was yesterday, but it has not disappeared. Quick runoff and street flooding are still possible, especially in poor-drainage spots and areas that are already saturated.

Timing And Commute Impacts
There may be a relative lull in the morning before showers regroup and become more widespread from around midday through the evening commute. Heavier pockets of rain can quickly slow traffic on city streets and major highways and may strand smaller vehicles in standing water. Build extra time into your trip and skip any tempting shortcuts that take you through flooded roadways.
Transit riders should keep an eye on service alerts before heading out, since localized slowdowns and delays are likely for bus lines and regional rail…
