With storms back in the forecast, it's important to clear up the difference between a tornado watch and a tornado warning.

This time-lapse video from our Society Hill Sky 6 camera shows the storm that hit Philadelphia on Tuesday evening.

Severe storms moved through the Philadelphia region on Tuesday, July 8 bringing heavy rains, strong winds, hail and several tornado warnings.

In Phoenixville, Chester County, the situation was far more serious. The rectory at St. Basil the Great Parish caught fire. Staff said a lightning strike caused the fire. In Douglassville, Berks County, a tree was uprooted and landed on a house, but as of Tuesday night, injuries weren't reported.

Downpours set off flood warnings Wednesday night for Philly and surrounding areas, and most of Chester County and northern Delaware. These conditions may be around until Monday, maybe longer.

An updated tornado warning was issued by the National Weather Service on Tuesday at 5:52 p.m. in effect until 6:30 p.m. for Bucks, Montgomery and Philadelphia counties.

A tornado warning issued for Bucks, Montgomery, Chester, and Delaware counties, and Philadelphia has expired. No tornados have been confirmed to have touched down as of Tuesday afternoon.

We’ve got tornadoes, flash flood warnings, and geyser manholes:

Flood waters are subsiding after Wednesday's rain, but there are more storm chances in the Philly region on Thursday.
