Reporter morgan radford, nbc news, newark, new jersey. As youve probably heard, theres snow in the forecast, for many people in the east, on the first day of spring. Meteorologist dylan dreyer has been studying the forecast models. Good evening, jose. It looks like this storm will stay farther out to seas which the american model, ironically, has been saying this whole time. The european model had this developing. The whole storm system is still organizing itself. It will strengthen really throughout the day on sunday. We have winter storm watches in rhode island and southeastern massachusetts, because as this storm stays to the southeast of nantucket, thats where we could see accumulating snow, especially the arm of cape cod. Into sunday morning, this area of low pressure develops, scattered rain showers through virginia and north carolina. Into sunday night, the storm intensifies off of southeastern massachusetts. Eastern long island, southeastern massachusetts, and rhode island have the best chance of seeing accumulating snow with outer parts of cape cod seeing as much as 6 inches of snow. The european model still hanging on to 1 to 2 inches possible in new york. The american model doesnt have a lot of accumulating snow for the big cities, just mountain snow in the appalachians. I do think this is going to be a near miss. Most of it is going to stay offshore and southeastern mass has the best chance of snow. Dylan, thanks so much.
