Southeast Pennsylvania



The image is highly contrasted in photoshop to show the lower cloud feature more distinctly. At various times there were a lot of low hanging clouds like this. I hesitate to call them wall clouds because they exhibited little to no rotation.

Above & above left: The view of the line from downtown West Chester, PA (If I remember right).



To the left & right, views of the storm as we drive away (on Rt.1 west/southbound). This chase was pretty much over, but sometime the view away from the storm is cool too.
Clarksville, Maryland (Storm is ~ 40 miles north along the MD/PA border)
