What happened

The episode as NWS PHI wrote it up.

A heat wave affected Central and Southern New Jersey from July 20th through the 23rd. This heat wave brought the highest temperatures of the year, mainly across the central and eastern parts of the state. The hottest days of the heat wave were the 21st and 22nd. Cloudiness on the 22nd prevented temperatures from rising even higher around the local Philadelphia area as the center of the hot air mass was over the Middle Atlantic States. A weak trough brought in slightly cooler air on the 23rd. A stronger cold front moved through the region late in the day on the 23rd and brought in a much drier and cooler air mass through the upcoming weekend (July 25th and 26th). Although a few locations still reached 90 degrees on the 24th, humidity levels were very low and tolerable. Atlantic Electric set a new usage record on the 22nd with 2,230 megawatts/hour. The highest temperatures included 98 degrees at the Atlantic City International Airport in Pomona and Pennsauken (Camden County), 97 degrees in Manahawkin and Toms River (Ocean County), and Belle Mead (Somerset County), 96 degrees at the Marina in Atlantic City (a new record for the day) and in Mount Laurel (Burlington County), 96 degrees in New Brunswick (Middlesex County) and Morristown (Morris County), 95 degrees in Millville (Cumberland County) and Freehold and Howell (Monmouth County), 94 degrees in Wertsville (Hunterdon County) and Cape May Courthouse and Dennis Township (Cape May County), 93 degrees in Piney Hollow (Gloucester County) and 92 degrees in Trenton (Mercer County).
