Two more days of unseasonably hot and humid weather in central and southern New Jersey occurred on the 27th and 28th.  Most high temperatures reached in the mid to upper 90s both days and combined with the humid air mass to produce afternoon heat indices of around 100F. Thunderstorms and then a cold front that moved through the area ended the excessive heat. Highest temperatures included 99 degrees in Berkeley Township (Ocean County), 98 degrees in Chatsworth (Burlington County), 97 degrees at the Atlantic City International Airport, Lumberton (Burlington County), Hillsborough (Somerset County), 96 degrees in Trenton (Mercer County), Millville (Cumberland County), Somerdale (Camden County), Seaside Heights (Ocean County), New Brunswick (Middlesex County) and Cream Ridge (Monmouth County) and 95 degrees in Rio Grande (Cape May County).
