Not only that, starting about 24 hours ago, the models started to come into agreement on a storm track that really put a walloping on the east coast but specifically in Boston. That track was pretty much confirmed this afternoon after the 12Z model runs and that is when you saw the NWS put up a blizzard warning for all of eastern Massachusetts.
Look at this GFS image at 1am early Monday morning. Once this storm hits the coast, it is really going to blow up. 980mb for a low pressure system is a really deep low. That is the equivalent of a category 1 hurricane. So winds are going to be a MAJOR issue tomorrow night. I am talking sustained winds of 35 mph with gusts over 60 mph.
The snowfall rate is serious as well. With the storm passing right over Nantucket, the watch of the rain/snow line becomes important. It is a very close pass to us. Usually, you want these storms to pass south of the islands, anything closer draws in too much warm ocean air. This one will be a troublesome thing to forecast. No models can answer those questions. If the whole area stays snow, expect 12-24 inches with some towns getting close to 30 inches of snow. Yes, 30 inches. There is THAT much moisture with this storm.
But that rain/snow line will be a big factor. I suspect we stay all snow. The overnight timing helps keep temperatures down. And winds will primarily be blowing from the north east, blocking the warmer air from penetrating further inland than Cape Cod.
It starts after noon tomorrow people and it is no joke. Top 10 snowstorm of all time is likely here. The storm will be an out and out hurricane tomorrow night and blizzard conditions will be at their peak overnight into early Monday morning. Monday morning commutes will be next to impossible. Take it very seriously.
I, for one, could not be happier! This is what it is all about. Huge blizzards. This is going to be our biggest storm of the year so enjoy it.
