Weekend Snow in the Northeast

December 12, 2013; 7:29 AM ET

Thursday morning

As very cold air crossed the mountains in Pennsylvania overnight, snow showers came along as well. Philadelphia had some of those during the morning commute. In the Buffalo area, the afternoon rush hour is a real nail biter. A band of heavy lake-effect snow is inching northward through the South Towns and could reach downtown Buffalo just as people are trying to get home. Wherever the band winds up, it will cause whiteout conditions and rapid accumulation. However, just outside the band it is just dry and very cold.

Here is my morning video. It includes two of several storm track scenarios.

The stronger the storm becomes, the heavier the snow on the cold side. However, a stronger storm will also tap much warmer air. This morning's NAM model suggests Philadelphia and New York City could get a few inches of snow late Saturday followed by a decisive change to rain. In Boston, however, the cold air appears more resilient, and this could result in a foot of snow. The GFS model last night portrayed a weaker storm with more cold air standing its ground.
