Snow Machine
























What you're seeing in the picture above is Mother Nature's snow making machine for the east coast. This is an image I grabbed from the latest NAM forecast model showing tomorrow and that is a pwerful Nor' Easter. A "Nor' Easter," as its name implies, is a storm that travels to the northeast. These storms can bring vicious wind, powerful waves and, more importantly, lots of snow to the northeasrtern U.S. and as far inland as the Great Lakes region. When these storms sit in the "sweet spot" they can be very efficient snow-makers. The sweet spot is just offshore, right on the border between the relatively warm Atlantic and the cold surface of the continental U.S. As the Low spins in this "sweet spot" it mixes these two very different air masses resulting in a powerful winter storm.

This storm will hammer the northeastern U.S. bringing power outages, travel delays and a ton of snow! So what does this mean for us? Well, we could see a fair amount of snow over the next 24-36 hours. Snowfall totals are very tough to predict but as warm air wraps around the storm and mixes with the cool air already in place in our region the result is accumulation. Although the bulk of this snow will stay well to the east, this "wrap-around" snow could result in 2-5cm tonight with an additional 5-10cm tomorrow and the potential for a few more flakes into Friday (before changing back to rain). In short, 10-15cm's is possible over the next day or so and there is the possibility for higher totals depending on temperature and the track of this powerful Nor' Easter. Oh...and it will be windy.
