Lake effect snowdrifts

Liverpool, NY is in the lake-effect snow belt SE of Lake Ontario.  What that means is whenever the wind flows across the lake if we are lucky it is cloudy and if we are not lucky it snows.  Because the predominant wind in the winter is from the NW snow is common, clear skies are rare.  On February 9, 2011 we had a rare clear day with a reminder of the previous night’s weather when wind-blown snow nearly filled the path with drifts.

Classic Comma Head Extratropical Cyclone over the Eastern U.S.

This extratropical cyclone shows a classic comma shaped cloud system usually associated with dangerous winter weather. In this picture we are seeing the cyclone in its mature, or occluded, stage, when the storm begins to lose its ability to deepen. Soon this storm will begin to shear into a persistent, cold-core low.
