Another hot and very humid air mass moved into New Jersey on the 28th. In most areas this hot spell produced some of the highest heat indices of the summer as they reached around 105F during the afternoon of the 29th. Even shore areas baked on the 29th and 30th as westerly winds kept the sea breeze from forming. July 30th was the hottest day (99 degrees) of the summer at the Atlantic City Marina. A cold front moved through the region during the night of the 30th. While temperatures on the 31st still reached into the 90s, dew point temperatures and the moisture content of the air mass was considerably lower. The apparent temperature (or heat index) matched and did not exceed the afternoon high temperatures. More humid air again moved in during the start of August. The string of days with high temperatures of 90 degrees or higher for inland locations did not end until August 5th or 6th. There were several reports of heat related illnesses, most were along the shore. Cooling centers for senior citizens were opened in Middlesex County. The hot weather and high humidity levels taxed electric utilities and the PJM Interconnection issued a usage advisory . Both Jersey Central Power and Light and Conectiv Power Delivery asked customers to use electricity prudently.
