Wider weather episode
A cold front moved through the mid-Atlantic on February 22, with a developing wave of low pressure tracking northeast along the front just inland from the Atlantic coast. This fast moving system brought a period of steady precipitation to the region mainly during the morning and midday hours on the 22nd. A cold air mass was in place ahead of the system, causing precipitation to start as snow. Southerly winds ahead of the cold front brought warmer air into the region, causing a change from snow to rain in many areas. Despite it being a fairly atypical setup for wintry precipitation in the region, a brief but intense period of snow affected much of eastern Pennsylvania and northern New Jersey. Several inches of heavy, wet snow fell in just a few hours, causing considerable disruption on area roadways.
