My neighbor accused me of enjoying all these snowstorms. I enjoyed all the fluff bombs in January but I HATED the cement I shoveled for the last 36 hours. Whether I like it, whether you hate, whether you are indifferent is irrelevant to mother nature. Another snowstorm is on the way tomorrow night. Now if you live outside of 495 it may track far enough offshore so that only 1-3" of snow falls. The Cape and Southeast MA will not be so lucky. The details...
General Overview
Here is the 4 PM surface chart. The low is located along the IL/IN/KY border

This storm is going to explode when it reaches the coast.
Timing, Impacts, Accumulation
Light rain/snow will move across Southern New England between 1-4 PM tomorrow. By 7 PM the storm will be located south of Cape Cod and will be gaining strength

| WPC Surface Forecast 7 PM Saturday |
The radar at the same time shows moderate to heavy snow across Eastern MA, the Cape, and Martha's Vineyard. Nantucket looks to be mainly rain for this event

It should be noted that several models are closer to the coast. That would put Central MA in play for heavy snow. As of now I think Bristol, Plymouth, and Barnstable Counties get the most snow/highest wind and the National Weather Service agrees, having posted Winter Storm Warnings and Blizzard Watch in these areas

| 02/14/14 NWS Headlines |
Power outages are likely across SE MA. Snow should be done by 5-6 AM on Sunday. If the storm is closer it will linger longer. I am in complete agreement with the NWS on this so here is their snowfall accumulation expectation

I will update as needed tomorrow
