LANCASTER – If you have to drive this morning, be alert as temperatures in the teens and yesterday’s snow have caused slick conditions on area roadways. Main roads have some snow and icy spots while secondary and back roads are the most challenging. Be alert for the possibility of black ice on roads, bridges, and overpasses. Allow extra travel time for your morning commute. Slow down and allow plenty of room between vehicles and you should make it to your destination. Road crews are out treating area roads.
