Winter Weather in Eastern Chester, Pennsylvania

Light freezing rain fell. Radar data and observations from surrounding counties confirm a brief period of freezing rain occurred.

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.
