    Arctic Blast With Snow Takes Aim on Pittsburgh

    By By Alex Sosnowski, expert senior meteorologist.

    Colder air will blast into Pittsburgh this weekend with a chance of accumulating snow.

    Prior to the arrival of the arctic air, temperatures will reach the 50s Friday.

    A moist flow from the Gulf of Mexico will bring clouds with the warmup, and may bring spotty rain to the area Thursday night and Friday.

    The first push of cold air will arrive on Saturday with gusty winds and a period or two of snow.

    Temperatures will likely hold in the 30s Saturday and could actually fall during the day. Motorists should be on the lookout for slippery spots developing, especially in the higher elevations east of the city.

    A second push of cold air from the Arctic will arrive Saturday night and will be accompanied by gusty winds lasting into Sunday. Gusts can top 40 mph. RealFeel® temperatures will plunge into the teens and even the single digits at times.

    Any untreated surfaces made initially made wet by the snow will freeze.

    It is this second blast that will set up locally heavy lake-effect snow in parts of eastern Ohio and western Pennsylvania to northern West Virginia. Several inches of snow could fall where the bands of snow persist.

    Temperatures will stay below freezing (32 degrees Fahrenheit) throughout the day Sunday.

    Winds and temperatures will ease up early next week.
