Conditions over the next 12 hours in the Pittsburgh area KDKA Weather Center

Monday will be a chilly one with morning lows feeling the teens, highs back in the upper 30s (near normal), and then we get back into the mid to upper 40s for Christmas Eve! 

Monday night and early Tuesday morning, we do have the chance for a wintry mix and possibly a brief period of light freezing rain for areas east. It'll all depend on timing and temperatures. 

Precipitation chances over the next week KDKA Weather Center

If the ground is freezing or below, the rain showers that fall will freeze on contact, and if it's colder for some higher elevations, we could see a mix. Just be aware that some slick spots are possible. Tuesday, we warm up in the upper 40s with rain showers.

Temperatures will be in the 40s for Christmas Eve and mostly cloudy, and then the 50s for Christmas Day with a few rain showers in the morning, so unfortunately, it's not looking like a white Christmas but just a soggy one.
