Freezing rain continued to fall in the north and west suburbs while Philadelphia, South Jersey and Delaware saw mostly rain overnight. It's all part of a winter storm that created a mess on roads throughout the region Monday into Tuesday.
Snow moved into the area Monday morning -- leaving more than 4 inches in parts of Delaware -- before slowly changing into freezing rain, creating slippery conditions on untreated roads, sidewalks and side streets.
As snow that reduced visibility in most parts of the region by midday fell, some evening schools not off for Presidents Day began calling off classes and motorists slowed down on area roads as speed restrictions on the Pennsylvania Turnpike and other roadways went into effect. Hundreds of schools then opened late Tuesday as road crews worked to clear up slippery spots.
The weather also caused nearly 90-minute delays to arriving flights at Philadelphia International Airport.
The snow changed to freezing rain, which changed to rain as temperatures rose late Monday night. The freezing rain changed to rain in Philadelphia as temperatures hit 33 degrees. However, the freezing rain continued overnight in areas north and west of Philadelphia due to temperatures in the mid-20s leading to a Freezing Rain Warning for points north and west until 5 a.m. That will change into rain by the Tuesday morning rush but some slick spots could remain.
The rain will continue, heavy at times, into Tuesday afternoon -- bringing a possibility of flooding in some spots -- before the wet weather finally clears by the evening commute.
Tuesday's high will be around 60 degrees.
By late Monday, more than 4 inches of snow had fallen in parts of Delaware and 1 inch or more had fallen in Philly, the suburbs and South Jersey. Snow amounts were limited before the change to rain outside of points to the south where snow fell while temps remained lower.
In Delaware, DelDOT dispatched as many as 500 workers in an attempt to get ahead of the storm. PennDOT dispatched crews ahead of snow falling in Pennsylvania in hopes of getting ahead of the potential icy conditions. PennDOT also reduced speeds on the Pennsylvania Turnpike and some other major area roads including the Vine Street Expressway and Route 309.
