Forecast Map for Weekend Storm


Map Created: January 15, 2010
Time Period: January 17-19, 2010
Precipitation Type: Rain, Freezing Rain, Sleet, Snow

Storm set up: A storm moving to the west of the Appalachian Mountains will transfer its energy to a developing coastal low that moves close to the region.

Details: The clipper will produce snow amounts of about 3 to 6 inches up to western Pennsylvania and far western New York. The Appalachian Mountains will act as a barrier for the snow, and the clipper will then transfer its energy to a weak storm offshore. This would leave places east of the Appalachians with a light snowfall, generally less than an inch, though with cold temperatures resulting in high snow ratios, some places could be looking at locally higher snowfall amounts with up to 2 inches. The general bust zone with the smallest snow totals is currently expected to be in southern Maine extending to Massachusetts, however this could also end up extending towards New York City if the actual scenario ends up being drier than currently expected.

Forecast for NYC Tri-State Area: Light snow showers will start on Thursday night and continue through Friday, with total accumulations less than an inch of snow.
