As snow began to fall on parts of the region, the Pennsylvania Department of Transportation reduced the speed limit on several major roadways in east-central Pennsylvania because of the winter storm.
PennDOT says the speed limit Monday is now 45 mph on Interstate 78 in Berks, Lehigh and Northampton counties, Interstate 176 in Berks County, and parts of US Routes 22, 222 and 422 and state route 33 and 309.
By mid-morning there were already a slew of crashes including wrecks on the Pa. Turnpike, I-95 and other major roads.
All public schools in the School District of Philadelphia are closed Monday and nonessential employees in the governor's jurisdiction are being allowed to report up to three hours late due to the storm expected to bring a mixture of rain, sleet, freezing rain and snow to much of the commonwealth.
Forecasters expect 4 to 8 inches for Philadelphia and along the I-95 Corridor.
