    A Winter Weather Advisory will be in effect Wednesday for much of the area, and a Winter Storm Warning for the mountains.

    Snow will start before sunrise south of Pittsburgh, then move north through the rest of the area during the morning.

    Roads will quickly become snow covered, and snowfall rates could be as heavy as 1 inch per hour at times. The combination of steady snow and rush hour traffic will lead to major delays as road crews try to keep roads passable.

    STORM TRACKER: Hour-by-hour look at snow, wintry mix for Wednesday

    Several inches of snow will fall, then a mixture of sleet and freezing rain will move into the area by mid-morning. A layer of snow, then a layer of ice on top will make travel hazardous through at least noon for many locations.

    Temperatures will climb above freezing by the afternoon, with the wintry mix changing to rain.

    Rain could be steady at times, and drains clogged by snow and ice could lead to ponding on roads.

    This is a tricky storm as warm air moves in from the south and snow changes to freezing rain, sleet and rain. Check back for updates from Severe Weather Team 11.
