After a record-breaking polar vortex, an ongoing arctic freeze will ensure that snow dominates the landscape, such as in this Tamaqua scene taken noon Thursday during a not-so-balmy high of 12 degrees. All of Pennsylvania is impacted by the polar plunge; Lake Erie reportedly is 95 percent ice-covered. Travel concerns and higher-than-normal home heating costs for many area residents will continue to be a factor as no warm-up is expected until February.
