A cold front moved through the region yesterday, producing heavy rain and flash flooding especially in western NJ and eastern PA. Temperatures will fail to cool down behind this front, however, rising back into the low to mid 80s across most of the area with mostly to partly sunny skies. A frontal boundary will affect the region from Thursday through Saturday, however, with additional scattered storms expected, followed by a cool down by next weekend and next week.
Sunday, July 28 Observations:
A slow moving cold front approached the region, producing widespread rain and thunderstorms especially west of NYC. Scattered storms initially affected eastern PA and western NJ in the morning hours, while a weakening area of scattered showers from severe storms to the south moved through NYC in the early afternoon. During the mid-late afternoon hours, a line of heavy thunderstorms developed over eastern PA, slowly moving east through western and central NJ, producing heavy rainfall and strong winds with most locations receiving 1 to 2 inches of rain; locally higher totals were reported in Morris county with localized flash flooding. Storms weakened as they reached the immediate NYC area in the evening with 1/4 to 1/2 inch of rain, and collapsed to the east of NYC with under 1/4″ in western LI/CT. Temperatures were cooler due to the cloud cover and rain, peaking in the mid 70s to low 80s across the area.
