PITTSBURGH (KDKA) -- It's finally a dry start to the day, but we won't get to enjoy it for very long as rain showers will begin moving in after 4 p.m.
Rain and snow showers are expected to continue through the overnight hours.
Rain, a wintry mix, and snow is expected later this evening. Here is an onset time graphic when precipitation will return. Warm ground conditions should help keep winter impacts low; areas near I-80 may receive 1-2 inches of snow. pic.twitter.com/mDeVVrqAr8

The set-up tonight is a little interesting as the rain and snow will be due to a warm front lifting in from the south. As it slides through, some areas will start with snow, quickly turning over to rain.
A Winter Weather Advisory has been issued for Mercer, Venango, Forest, Clarion, and Jefferson Counties in northwest PA for tonight into Thursday morning. Snowfall accumulations between 2-4" will be possible, with the heaviest snow falling around midnight. pic.twitter.com/hOl64fozLr
