PITTSBURGH — Winter weather alerts have been posted for much of the area into Friday as a blast of winter weather barrels into the area.
A Winter Weather Advisory is in effect for Armstrong, Butler, Indiana and Lawrence counties. A Lake Effect Snow Warning is in effect for the I-80 corridor and a Winter Storm Warning for the mountains. A Winter Storm Warning is in effect for portions of Westmoreland and Fayette counties until 7 a.m.
The first round of snow arrives later this evening and may start as rain in spots initially with temperatures several degrees above freezing. However, much colder air blasts in overnight, which could lead to icy spots and a quick accumulation of snow for the morning commute.
Lake-effect snow showers will continue off and on throughout the day, especially north of Pittsburgh and east into the higher elevations, where several inches of snow will accumulate. Winds may gust over 35 mph at times throughout the day (even higher over the mountains), which will keep wind chills in the single digits most of the time.
Lake effect snow showers will taper off Friday before a warm up later in the weekend.
