Nor' easter

Northeast storm—(Also called northeaster, nor'easter.) A cyclonic storm of the east coast of North America, so called because the winds over the coastal area are from the northeast.
They may occur at any time of year but are most frequent and most violent between September and April. Northeast storms usually develop in lower–middle latitudes (30°–40°N) within 100 miles east or west of the coastline. They progress generally northward to northeastward and typically attain maximum intensity near New England and the Maritime Provinces. They nearly always bring precipitation, winds of gale force, rough seas, and, occasionally, coastal flooding to the affected regions. So this is the official definition of a nor'easter from the AMS glossary.
Many times what I find interesting about these storms is that they tend to get stronger as they head up the eastern coast line. This week a storm system moved across the Atlantic near the Carolina coast lines before heading towards New York and becoming a 'Mega' system when it hit New England. The Great Lakes region also made a contribution to this system as low pressure moved across the area quickly yesterday and joined forces with an already strong 'nor'easter.
So far snowfall totals are anywhere from 12 to 20 inches of snowfall.

What I have noticed about these storms when I lived in Philly, PA (and the February of 78-79 is a GOOD example), is that they DO INDEED intensify after getting past the Appalachian/Pocono/Catskill mountains, and with the close proximity to the Atlantic, those mountains apparently don't allow the moisture to come all that far BACK inland (about 100 miles...tops). It all hangs out around the coast.

It was nice to get "snowed in" at my (then) girlfriend's apartment (in NJ), though, so it's never ALL that bad.
Shoveling snow up past my car's WINDSHIELD, however, WAS all that bad.
I will be watching this one.

Bobby,
78-79 were phenomenal years for snowfall here and across the entire east coast. The '78 storm is in fact a model of what the 'perfect storm' would be for this area to get heavy snowfall. Of course the nor'easter is a whole 'nother beast but you can see how systems that move through our area can have an impact on snowfall across the east.
