Both excessive heat and more humidity returned to central and southern New Jersey starting on Independence Day and lasted until the 7th.  The heat and humidity taxed people in the southeastern part of the state that still had  no power from the Derecho that went through overnight on June 29th.
High temperatures on the 2nd and 3rd were around 90 degrees and humidity levels were relatively low.  High temperatures on the 4th reached into the lower and mid 90s and combined with more humidity produced afternoon hourly heat indices of near 100F.  High temperatures on the 5th and 6th were generally in the lower to mid 90s, with hourly afternoon heat indices near 100F. The heat and humidity peaked on the 7th with high temperatures around 100F and afternoon hourly heat indices peaking around 105F. A thunderstorm complex  preceding a cold front helped bring lower temperatures during the evening of the 7th and the cold front cleared the southern part of the state during the morning of the 8th.  Coupled with more cloudiness, high temperatures were no higher than the lower 90s on the 8th and below 90F in most places on the 9th.
Highest temperatures all occurred on the 7th and included 101F in Lumberton (Burlington County) and Cherry Hill (Camden County), 100F in Trenton (Mercer County), Toms River (Ocean County), Wildwood (Cape May County) and Atlantic City (Atlantic County), 99F in Belmar (Monmouth County), South Harrison (Gloucester County) and New Brunswick (Middlesex County), 98F in Somerville (Somerset County) and Lakehurst (Ocean County), 97F in Woodstown (Salem County) and Kingswood (Hunterdon County) and 96F in Barnegat Light (Ocean County).
