What happened
The episode as NWS PHI wrote it up.
A protracted run of consecutive days with high temperatures of 90 degrees or higher started in New Jersey on July 23rd. It lasted as long as 16 days in some parts of Southern New Jersey through August 7th. Dispersed within this run were two periods of both excessive heat and humidity: from July 23rd through July 25th and again from July 29th through August 1st. A strong cold front moved through the region the afternoon and evening of August 1st. This brought in considerably drier air, the driest air since mid July. Because of the extremely dry ground conditions, diurnal temperature ranges remained larger than usual. High temperatures reached into the 90s through August 7th in southern parts of the state. That day a stronger cold front moved through and coupled with cloudy skies and light rain on August 8th brought an end to the string of consecutive days with high temperatures of 90 degrees or higher. The continued excessive heat and lack of rain parched non-irrigated farms across the state. During the summer of 1999 there were 18 heat related deaths in Northwest and Southern New Jersey; most occurred during the Independence Day Weekend.For most places the highest temperatures during this hot spell occurred on July 28th and July 31st. They included 102 degrees in New Lisbon (Burlington County), 101 degrees in Flemington (Hunterdon County), 100 degrees in Mount Holly (Burlington County), Pennsauken (Camden County) and Newton (Sussex County), 99 degrees in Estell Manor (Atlantic County), New Brunswick (Middlesex County), Trenton (Mercer County on August 1st) and White House Station (Hunterdon County), 98 degrees at the Atlantic City International Airport (Pomona), in Belvidere (Warren County), Lumberton (Burlington County) and Somerville (Somerset County), 96 degrees in Hightstown (Mercer County), Millville (Cumberland County), Wantage (Sussex County) and the Marina within Atlantic City (Cumberland County), 94 degrees in Andover (Sussex County) and 92 degrees in Long Valley (Morris County). Shore areas had some relief from the heat as seabreezes developed along the shore. The hottest days along the shore were the 25th, 28th and August 1st. New daily high temperature records were set on August 1st at both the Atlantic City International Airport (96 degrees) and the Marina within Atlantic City (94 degrees).
