A New England surface map for 12Z (7AM Friday Dec 12, 2008 (click image for larger map) at the height of the storm shows a low pressure center tracking along a coastal front. It is a warm front because it is being advected toward the coast by the southerly winds in the warm sector of the low pressure system. This front had been in stationary for the previous two or three days. These winds overrun the front and the White mountains of New Hampshire. Cold air remains wedged northwest of the front in the region of strong precipitation northeast of the front. Freezing rain and sleet at this point extended all the way across Vermont into Canada. The rawinsonde stations of Albany, NY (ALB), Gray, Maine (GYX) near P0rtland), and Cariboo, Maine (CAR) are marked with boxes. The station in northern New Hampshire is Littleton (HIE).
