Winter Weather Advisory Issued

PITTSBURGH — Another round of snow is on the way and will bring the threat of snowy roads and icy travel as the week comes to a close. Snow will arrive before sunrise Friday with steady snow at times, making it difficult for crews to clear the roads. The Friday morning commute will be slow and school delays will be possible with several inches of new snow expected by Friday evening. Colder temperatures blow in behind the system this weekend with high temperatures again struggling to get out of the teens. The National Weather Service has issued a Winter Weather Advisory beginning at 1 a.m. Friday until Saturday at 10 a.m.
