It remains too early to speak with certainty on snowfall amounts with the event for later Sunday into Monday, but it's not too early to give at least a rough initial estimate of potential snowfall. The premise of this event is that a burst of moisture aloft will collide with air that will be marginally cold enough for snow, producing some Sunday afternoon and evening snow, blossoming from southwest to northeast, in Southern and Central New England. With an onshore wind, and ocean temperatures in the upper 40s, warmer air will push inland from the shore, changing snow and mix to rain for much of Southern New England and communities near the coast. The farther north and inland one is, however, the less likely a change to rain is. As such, an early estimate of minimum likely snowfall amounts can be given - but use this as guidance at this early stage...a change in precipitation amounts and/or storm development will have an impact on this forecast.
