One of the harshest arctic outbreaks in years occurred in New Jersey on the 7th. Some record calendar day low temperatures occurred and combined with strong northwest winds produced wind chill factors as low as 15 to 25 degrees below zero in most areas that morning. Low temperatures were near zero. High temperatures struggled to reach double digits. The excessive cold caused many schools to either cancel classes or have delayed openings. Some delayed opening also occurred on the morning of the 8th in the northwest part of the state. AAA Mid-Atlantic reported an 81 percent increase in service calls, mainly for dead batteries. Amtrak reported extensive delays in its rail service. The cold weather also affected power supplies. PJM Interconnection, the agency that oversees the electric grid supplying the region, said electricity suppliers were struggling to keep up with surging demand as the cold forced some power plants to shut. An all-time winter record usage was recorded at 8 a.m. EST on the 7th, 138,600 megawatts surpassing the previous record from 2007. Utilities asked their customers where possible to switch to diesel or fuel oil.
While some low temperatures were higher than what occurred on January 4th, the wind made it feel much colder than the air temperatures. Low temperatures included 8 degrees above zero in Stone Harbor (Cape May County), 6 degrees above zero in Woodbine (Cape May County) and Ship Bottom (Ocean County), 5 degrees above zero at the Atlantic City International Airport and Millville (Cumberland County), 4 degrees above zero in Cherry Hill (Camden County), 3 degrees above zero in Belmar (Monmouth County), Berkeley Township (Ocean County), Mount Laurel (Burlington County) and South Harrison (Gloucester County), 2 degrees above zero in Trenton (Mercer County) Somerville (Somerset County) and New Brunswick (Middlesex County),  1 degree above zero in Morristown (Morris County), zero in Sussex (Sussex County), 1 degree below zero in Hackettstown (Warren County) and Kingwood and 4 degrees below zero in Netcong (Morris County).
Lowest hourly wind chill factors included (they all occurred during the morning of the 7th) 21 degrees below zero in Kingwood (Hunterdon County), 20 degrees below zero in Wantage (Sussex County), Berkeley Township (Ocean County) and Basking Ridge (Somerset County), 19 degrees below zero in Belmar (Monmouth County) and Morristown (Morris County), 18 degrees below zero in Trenton (Mercer County),  at the Atlantic City International Airport and McGuire Air Force Base (Burlington County), 16 degrees below zero in Millville (Cumberland County) and 12 degrees below zero in Wildwood (Cape May County).
