The National Weather Service has issued a Hazardous Weather Outlook statement for much of Massachusetts, including Plymouth.
This morning expect a dusting of snow, totaling less than a half-inch, mainly before 10 a.m. But the main event is expected to begin Thursday night.
Here's what the NWS has to say:
Confidence continues to increase in the potential for a very significant winter storm Friday into early Saturday. While light now may have developed Friday morning, the worst of the storm looks to occur Friday afternoon into early Saturday. The exact details of the storm remain uncertain, since the event is still 72 hours in the future. However, there is the potential for a foot or more of snow in some locations. The main uncertainty at this point is how far west the heaviest snow will reach into the distant interior. The other concern is, will there be any mixing along the coastal plain that would cut down on potential snow accumulations. In addition, there is a moderate to high probability that a period of strong winds will require the need for wind headlines across portions of the coastal plain late Friday into early Saturday. Finally, there is a moderate to high probability that a round or two of minor to moderate coastal flooding will occur along the Eastern Massachusetts coastline during high tide Friday night and again Saturday morning.
Here's the forecast for the next three days.
Thursday: Increasing clouds, with a high near 25. Northwest wind 7 to 9 mph becoming northeast in the afternoon.
Thursday Night: A chance of snow, mainly after 3 a.m. Cloudy, with a low around 24. Northeast wind 5 to 7 mph becoming light and variable. Chance of precipitation is 30 percent.
Friday: Snow, mainly after noon. High near 38. Chance of precipitation is 80 percent.
Friday Night: Rain and snow, becoming all snow after 8 p.m. The rain and snow could be heavy at times. Low around 26. Windy. Chance of precipitation is 90 percent.
Saturday: A chance of snow. Mostly cloudy, with a high near 29. Blustery. Chance of precipitation is 50 percent.
