It could be another icy commute for travelers early Thursday morning.
The National Weather Service in Pittsburgh has issued a special weather statement, advising of the possibility of hidden ice on roadways in most of Western Pennsylvania, southeastern Ohio, northern West Virginia and part of western Maryland.
The weather service said that water from melting snow yesterday accumulated in some spots on roads. With temperatures below freezing, that standing water has frozen and caused patches of so-called black ice.
Motorists should pay particular attention to secondary roads, and bridges and overpasses on all highways. Roads that look wet actually could be covered by a thin sheet of ice.
Temperatures across the region are not expected to climb higher than freezing until about 10 a.m.
