An unseasonably hot and humid day produced high temperatures in the mid to upper 90s in most of New Jersey. South of the Interstate 80 corridor, the combination of heat and humidity levels, produced maximum hourly heat indices that reached between 100F and 105F.  The heat and humidity set the stage for the powerful derecho that affected the southeast part of the state later that night. High temperatures on the 29th included 99 degrees in Mansfield (Burlington County), 98 degrees in Lumberton (Burlington County), 97 degrees in Sicklerville (Camden County), 96 degrees in Andover (Sussex County) and Seaside Heights (Ocean County), Trenton (Mercer County) and Lakehurst (Ocean County), 95 degrees in Somerville (Somerset County), Belmar (Monmouth County), New Brunswick (Middlesex County), Woodstown (Salem County), Clayton (Gloucester County) and Millville (Cumberland County), 94 degrees at the Atlantic City International Airport (Atlantic County) and 93 degrees in Kingwood (Hunterdon County), Stewartsville (Warren County), Wildwood (Cape May County) and the Marina in Atlantic City (Atlantic County). While some high temperatures on the 30th reached into the lower 90s, the derecho brought in slighter drier air in its wake.
