These “headlines” were issued by the National Weather Service because of expected freezing rain (icy glaze) tonight.

Communities in the warning area have the potential to see significant icing this evening, tonight and Tuesday. The communities in the advisory area could have some travel issues because of freezing rain.

The most significant freezing rain will occur in the ridges, and this looks to happen overnight into Tuesday.

When all is said and done, some areas in the higher terrain could see 1/4 inch of ice. This could lead to dangerous travel and power outages. Counties north of Pittsburgh likely will not see that much icing, but a thin glaze of ice could lead to potential travel issues.

The precipitation will start wrapping up later Tuesday. While Tuesday’s temperatures will be mild in Pittsburgh, at least for January, it will get much colder for the second half of the week and into the weekend.
