Summary
An Old Fashioned Winter, or at least December 2007, ended on a snowy note across Vermont and northern New York. A fast moving coastal storm passed offshore of southern New England during the morning of December 31st, yet it was enough to deliver a moderate snowfall to much of Vermont and the Champlain Valley of New York. Snowfall totals from this "end of the year" storm ranged from 2 to 4 inches in the St. Lawrence River Valley to 3 to 7 inches in the Adirondacks and Champlain Valley of New York as well as much of Vermont. These snowfall totals added to an already significant December snowfall throughout the North Country, including the Champlain Valley where Burlington's December snowfall of 46.2 was the 4th highest December total since records have been kept in 1883.
On Sunday morning (30th), a stationary frontal boundary was draped across the southeast United States with weak low pressure slowly developing along this boundary. This frontal boundary tapped moisture from the Gulf of Mexico and was the focus for much needed rainfall in the drought affected areas of the southeast United States during Sunday. Eventually, a surface low lifted out of the southeast United States to the Mid-Atlantic coast Sunday night and then quickly moved east of Cape Cod by Monday morning.
Snow began to overspread New York and Vermont around Midnight Monday (31st) with snowfall rates rapidly increasing to near an inch per hour at times, but this was a quick-hit storm with steady accumulating snowfall ending across much of Vermont and northern New York by mid-morning.
Meanwhile, another strong disturbance moved from the Pacific Northwest on Sunday (30th) to the Mississippi River Valley by Monday afternoon (31st) with a New Years Day arrival expected across New England and New York.

Surface low pressure traveled near the 40 degree north latitude, 70 degree west longitude coordinates early Monday morning before moving into the Gulf of Maine. Climatologically, the heaviest snowfalls for Vermont and northern New York occur when surface low pressure travels north and west of this 40N/70W benchmark, preferably between Cape Cod and Boston, Massachusetts.

Much needed rains in drought stricken parts of the southeast United States on Sunday (12/30) lift northeast reaching southern New England as mixed snow and rain Sunday night. Snow overspreads Vermont and northern New York around Midnight (EST) on Monday (12/31), but quickly exits the much of the region by mid-morning Monday.
Infrared Satellite and Surface Time Lapse
Saturday Night at 7pm EST (12/29) to Monday Afternoon at 1pm EST (12/31)
Click on image to enlarge
Abundant moisture tapped from the Gulf of Mexico traveled along a frontal boundary draped across the Gulf coast and the southeast United States Saturday night and continued Sunday. This brought some much needed rainfall to drought stricken portions of the southeast United States and Carolinas. Eventually, this moisture and surface low would move to the Mid-Atlantic coast Sunday night and affect New England late Sunday night and Monday morning. Meanwhile, another energetic disturbance has moved from the Pacific Northwest on Sunday (12/30) into the Mississippi River Valley by Monday afternoon (12/31) and will eventually affect the Northeast on New Years Day 2008.
