Pennsylvania turnpike lifts speed restriction in most areas

PHILADELPHIA - February 18, 2014

Officials said Tuesday that the limit would remain in effect "until the weather improves."

The state transportation department also imposed a 45 mph speed limit on some roads due to the winter storm.

The National Weather Service says the storm brought some rare "thundersnow" - heavy snow with embedded thunder - to western Pennsylvania.

Forecasters say 6.5 inches of snow has been reported in Butler County, 6 inches in Lawrence County and more than 5 inches in Somerset County, with 3 inches at Philadelphia International Airport.
