A rare powerhouse storm system is sweeping into New England, bringing chilly temperatures, strong winds, and heavy rain this weekend. Meteorologists warn of accumulating snow, especially in the high peaks of Vermont, New York, and New Hampshire, raising the possibility of snow showers in Massachusetts as well. Forecasts indicate that parts of Maine and New Hampshire could also see some snow later in the week, as an Omega Block influences the late spring weather pattern. Residents should prepare for a gloomy, rainy weekend as the region rounds out spring, with significant impacts expected from the wintry storm.
