Ghiorse: Big Winter Storm Update - Monday PM

John Ghiorse
March Weather Madness Storm # 3 is just getting its act together off the coast of the North Carolina this morning. It will move toward us and pass southeast of Southeastern New England late tonight and tomorrow. 
 
This one promises to bring more snow accumulation to areas that saw very little accumulation in storms 1 and 2 mainly because it is expected to pass us farther offshore and the chances of rain mixing in or changing over is not likely except on the Cape and Islands. Of course, the accumulation forecast is very dependent on the storm track ... 50 miles one way or the other can made a big difference in the total amount of snow at any given location.

All of the weather data is not in agreement on that track thus there is a rather wide range of accumulation forecasts varying from 6" to as much as 18". My forecast falls pretty much in the middle in the range of 9"-16" with the snow beginning late tonight and extending through much of tomorrow.
 
There will be the accompanying strong, gusty northeast winds (30-50 mph) with attending coastal flooding especially along the Eastern Massachusetts and Cape Cod shorelines. Blowing and drifting snow will make travel very difficult if not next to impossible, especially for tomorrow morning's commute. 
 
I'll have another update later this afternoon or early evening as more data arrives.
