Big Storm On The Way!

This winter has been very entertaining, to say the least, here in the NYC metro area. We had a huge snowstorm in mid December, which dumped record snows across parts of Long Island. We had a storm that was so close, you could literally taste it, but did not quite make it all the way up to our area.

The mid-atlantic has seen record snowfall this season with tremendous snow storms, dropping several feet of snow. Even the deep south has had unusual snow events.

When I think about the winter that Florida had, this was may be the most interesting aspect of all, being a traveler to the state many times and having family there. Florida had a record stretch of cold weather in early January. Snow fell in areas that had not seen anything of the likes since 1977.

Much of this winter was dominated by the negative phase of the North Atlantic Oscillation (-NAO). What's interesting is that it hasn't really been brutally cold, but it was the meridional extension of how far the cold air was able to penetrate south this winter which was truely amazing.

I also think about the blocking of storms just to our south and how most of new england has wondered what has happened to the snow, while those to the south were buried. Well, that is until this week.

So, here we are again, on the verge of another significant snow event. Though this storm will likely be the most intense of the season, it might or might not be the biggest snowfall of the season, depending on where you live. Every storm is unique in some way. This storm will be unique in it's long duration. It will track to a favorable position that generally gives the tri-state heavy snow, but will then stall out and perhaps retrograde north and west slightly, before finally weakening and move out to sea.

Temperatures are just cold enough to support snow across a good portion of our area. This will be a heavy wet snow, that will be a pain to shovel.

Below is the projected snowfall accumulation map.
