While the track of the first major winter storm in two years isn't clear, what is clear is that it will have a major impact on Weymouth and all of Eastern Massachusetts.
The National Weather Service is calling it a "potential historic winter storm and blizzard" that's expected to drop between one and two feet of snow across much of the region Friday into Saturday.
A blizzard watch was issued for western Norfolk County Wednesday afternoon, predicting accumulations between 12 and 24 inches.
Closer to the coast, the storm is expected to drop heavy wet snow, resulting in lower accumulations that may or may not mix with rain, depending on the storm's track. Weymouth should still expect between 8 and 15 inches of snow.
According to the NWS, "heavy snow and very strong winds will bring the potential for near-blizzard conditions. The worst of the storm will be Friday night into Saturday morning. Snowfall rates of 2 to 3 inches per hour are possible. Travel may become nearly impossible with blowing and drifting snow."
Friday morning will bring light snow which will increase as the day goes on. There may be a brief change to rain near the South Coast during the afternoon, but it should switch back to heavy snow by Friday night, when the bulk of the stom is expected.
The storm will also bring very strong northeast winds between 30 and 40 mph with gusts up to 65. The heavy windblown snow will mean visibility will be down to a quarter of a mile or less at times.
The NWS has issued a high winds watch beginning Friday evening. The strongest winds are expected late Friday night and into Saturday afternoon, that could result in some structural damage. There also may be some tree damage and scattered power outages. Cape Cod could see hurricane force winds, or winds higher than 74 mph or 64 knots.
