You may recall the unusually early nor'easter that brought snow to a good chunk of the area a few weeks ago. As we delve deeper into fall, and soon begin the winter season, these storms become more frequent. We know very well they can be difficult to forecast even a couple days away from their arrival. This is more often than not due to the proximity of the storm to the coast--- where as little as a 30-mile shift can make or break a snowfall forecast for any location. Here's a very good interactive map I was able to find that shows how this type of storm develops. It shows the key ingredients present during the late fall, winter, and early spring months that helps this unique storm form.
