Winter Weather in Middlesex, New Jersey

Light freezing rain fell. A COOP observer near Milltown reported 0.02 inches of ice accretion. Numerous motor vehicle accidents occurred, reportedly several dozen in Middlesex County alone, including a fatal accident on Route 34 in Old Bridge.

A developing wave of low pressure brought light precipitation to the mid-Atlantic on the morning of January 5, 2022. Warm air advection caused rising temperatures aloft over the region. However, surface temperatures were initially sub-freezing, and in some cases took several hours after precipitation began to move above freezing. This caused freezing rain to fall. A widespread light icing event transpired across the eastern mid-Atlantic as a result of this. While ice accumulations were no more than several hundredths of an inch, this event caused significant travel impacts during the busy morning commute hours of January 5.
