DISCUSSION: In light of the upcoming coastal low pressure system projected to develop and strengthen over the course of the next 24 to 48 hours, there are a number of different impacts expected across portions of eastern New England. As shown in the graphics above, there are also areas of uncertainty which remain at this time in terms of the snowfall forecast. This is primarily due to the uncertainty tied to the exact forecast position of the aforementioned low pressure system. As the forecast picture comes into a more clear view over next 24 hours, these forecast issues should hopefully get a bit less uncertain with time. Moreover, depending upon where you are located with respect to the coastline of eastern Massachusetts, southern Rhode Island, and eastern New Hampshire, conditions will vary significantly. The primary differences will vary by the extent of the possible mixing of precipitation that may occur as well as the maximum extent of the peak wind gusts during the height of the upcoming Nor'easter.
Attached here is an excerpt from the actual Facebook post courtesy of forecasters from the National Weather Service located in Taunton, Massachusetts: "Here is the latest forecast information for the upcoming major winter storm. We are expecting a widespread 14-18 inches of snow, falling at 2-4"/hour at times Tuesday morning and early afternoon. Isolated thunder-snow is also possible. Winds will gust to 30-50 mph inland and up to 60+ mph at the coast. Minor to moderate coastal flooding is possible. Please see attached for more information."
