PITTSBURGH — Allow some extra time to scrape the windshield and watch for a few icy spots as you head out early for Black Friday Deals. Temperatures dropped below freezing overnight and wet roads and sidewalks may become icy. Scattered snow showers will also move through the area with a coating to less than an inch of snow possible. You’ll need the extra layers too, with high temperatures below freezing and wind chills in the teens. Gusty winds will make it feel even colder early Saturday and Sunday morning with wind chills in the single digits and a continued stretch of below freezing weather is expected through the middle of next week.
