It took awhile but att noon light snow was falling northwest of the city and a mix of snow and rain was detected at Philadelphia International Airport as the precipitation finally battles through a wall of dry air.
As precipitation falls into the dry air, temperatures should drop. They fell from 42 at 11 a.m. to 38 at noon at the airport.
The National Weather Service continues its winter advisories for the region and is calling for 4 to 6 inches from this premature winter storm.
In the morning discussion, the weather service says that all the models now see a so-called "trowal" setting up over eastern Pennsylvania and South Jersey.
