Storm Coordination Message #1 – Tuesday 12/2/25-Early Wednesday AM 12/3/25 – Coastal Winter Storm Potential

Hello to all…

..We hope everyone had a great Thanksgiving holiday weekend period! A coastal storm will impact Southern New England likely bringing a plowable snowfall to interior Southern New England Tuesday Morning through late Tuesday Night with heavy rainfall and strong wind gusts to coastal Southern New England. Snowfall amounts are more uncertain than normal at this time range given model solutions are not completely aligned on the track, speed and intensity of the system..
..A Winter Storm Watch is now in effect from Tuesday Morning through late Tuesday Night for Franklin, Hampden, Hampshire Worcester, Northern and Central Middlesex and Western Essex Counties of Massachusetts for 6″ or more of snow. Areas of Northern Connecticut through Northwest Rhode Island through Western Norfolk and Southeast Middlesex Counties of Massachusetts should monitor for similar impacts if the storm track is far enough offshore. Some area of the Winter Storm Watch area could have a heavy wet snow which could result in isolated pockets of tree and wire damage and power outages..
..Coastal areas of Southern New England are likely to see mostly rain with perhaps a period of snow at the start and possibly at the end of the storm. Depending on the intensity, there could also be a period of strong to damaging winds that will bear watching. Rainfall amounts of 1-2″ with isolated higher amounts are possible..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Tuesday into Wednesday Morning for snowfall amounts and any rain gauge, wet snow damage/wind damage reports. Pictures and videos of storm damage and rain related flooding can be sent as a reply to this message via the WX1BOX Facebook/X/Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

A coastal storm will bring the region’s first more widespread, plowable snowfall to a good portion of interior Southern New England. the headlines depict the current thinking. Key factors include:

1.) Model spread is larger than normal at this time range with some reliable models stronger and closer to the coast while other reliable models are weaker and further offshore. This will impact the heaviest snowfall area and total amounts.
2.) There is no high pressure to the north that would aid in any storm system to bring down cold air. This means a further offshore track will still likely result in mostly rain at the coast line and perhaps interior Southeast New England depending on how heavy the precipitation is and if the heavier precipitation falls during daylight hours or at night.
3.) There could be an elevation component to this storm where higher elevations may have heavier snow than lower elevations even in the interior. Also, if temperatures are marginally near or just above freezing but precipitation falls as heavy wet snow, this could result in isolated pockets of tree and wire damage and isolated power outages.
4.) Coastal areas are expected to see mostly rain but depending on the track and intensity of the storm could see a period of strong to perhaps damaging wind gusts as the storm moves through later Tuesday and Tuesday Night through early Wednesday AM. Heavy rainfall is also likely in this area with 1-2″ and isolated higher amounts possible.
