What happened

The episode as NWS PHI wrote it up.

An unseasonably warm air mass for late March brought record breaking high temperatures across New Jersey from March 27th through March 31st. The warmest day for the shore was the 29th, for interior central and southern New Jersey the 30th and for northwest New Jersey the 31st.Statewide March 30th was the warmest March day of this century with a few locations reaching high temperatures of 90 degrees. Several locations across the Middle Atlantic States established new March monthly high temperature records. Morristown broke its previous March monthly record of 85 degrees set in 1977 with a high temperature of 89 degrees on the 30th. It was also the warmest March day of this century in New Brunswick with a high of 88 degrees. The Atlantic City International Airport in Pomona tied its March monthly record of 87 degrees set previously on March 29, 1945. The excessive heat contributed to a small brush fire along the New Jersey Transit lines in Middlesex County. New daily record highs were set at the Atlantic City International Airport on the 27th and 30th, at the Atlantic City Marina on the 29th and in Morristown on the 30th and 31st. Across the region, the highest temperatures included 91 degrees in Freehold (Monmouth County), 90 degrees in Mount Holly (Burlington County), Long Beach Island (Ocean County) and Belle Mead (Somerset County), 89 degrees in Morristown (Morris County), Toms River (Ocean County) and Washington's Crossing (Mercer County), 88 degrees in Cherry Hill (Camden County), Flemington (Hunterdon County), New Brunswick (Middlesex County) and Sussex (Sussex County), 87 degrees in Stewartsville (Warren County) and the Atlantic City International Airport, 86 degrees in South Harrison (Gloucester County), Seabrook and Millville (both Cumberland County), 84 degrees in Long Branch (Monmouth County) and at High Point (Sussex County), 83 degrees at Cape May Courthouse and 82 degrees at the Marina within Atlantic City.
