An early morning low end derecho moved through the region on the 13th which caused strong to severe thunderstorms to develop across southern New Jersey. The derecho moved off the New Jersey coast by late morning leaving a boundary across parts of the region. Later in the day, a strong low pressure system brought a cold front through the region, which sparked off more strong to severe thunderstorms across the area.
