An icy wintry mix replaced snow by the time most of Philadelphia and the suburbs stirred from their beds Saturday, creating dangerous conditions on the region's roads and delays at Philadelphia International Airport.
Temperatures rose -- though slowly -- throughout the morning and into the early afternoon as rain began anew.
From the overnight hours, when snow fell for a few hours, drivers and travelers were urged to take as much precaution and time as possible if they had to leave their homes at all.
The airport said the icy conditions forced dozens of flight cancellations by 7 a.m. Throughout the morning, the airport maintained a "delayed ground stop," which led to delays for numerous flights.
SEPTA Regional Rail experienced 30-minute delays throughout the day on several lines.

The dramatic change from icing conditions to nothing but clouds and rain comes courtesy of a steady flow of warmer air from the southwest. These winds continued Saturday night into Sunday. By Sunday morning, when another round of wet weather moves in, it will be even warmer, ensuring that only rain will fall.
The warmer air won't last, though, as a shift in the wind will drop readings back into the 40s.
