Areas north of Interstate 80 and the ridges are under winter weather advisories because they could get several inches of snow. 

A winter weather advisory covers Mercer, Venango, Forest, Jefferson and Clarion counties from 1 a.m. until 10 p.m. Wednesday. Another covers parts of Cambria and Somerset counties as well as the higher elevations of Fayette, Westmoreland and Indiana counties from 10 a.m. Wednesday until 10 a.m. Thursday. 

There's also a blizzard warning for parts of Maryland and West Virginia from 10 a.m. Wednesday to 10 a.m. Thursday. 

Areas south of I-80 will see some snow and a mix, but little to no accumulation is expected the further south you go because temperatures will be in the mid to upper 30s and the ground will be above the freezing mark. Pittsburgh and the surrounding areas may get half an inch, but it's mainly just going to be wet and windy. The high will be right around 40 degrees for the day. 

It turns frigid again on Thursday with lows in the 20s and wind chills in the teens. A few flakes are possible both Thursday and Friday, with highs only right around the freezing mark. 

The weekend looks like the Pittsburgh area could get a good bit of snow Saturday night through Sunday. Temperatures will fall throughout the day on Sunday from the upper 20s, so what falls will stick. We could be looking at another day for kids to go outside and play in the snow.
