Storm Coordination Message #2 – 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 is on track to 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. Model alignment and confidence has increased since the prior update..
..A Winter Storm Warning is now in effect from 7 AM Tuesday Morning through 7 AM Wednesday Morning for Franklin, Northern Worcester, Northern Middlesex, Western Hampden, Western Hampshire and Western Hampden Counties of Massachusetts for 6-9″ of snow with isolated higher amounts and the heaviest amounts in the higher elevations. The snow has potential to be heavy and wet potentially leading to isolated to scattered pockets of tree and wire damage and power outages..
..A Winter Weather Advisory is now in effect from 4 PM Tuesday Evening to 7 AM Wednesday Morning for Central Middlesex and Western Essex Counties Massachusetts and for Eastern Hampshire, Eastern Hampshire and Southern Worcester Counties of Massachusetts from 7 AM Tuesday Morning to 7 AM Wednesday Morning for 3-5″ of snow. If higher amounts occur, the snow will be heavy and wet and could result in isolated pockets of tree and wire damage and power outages..
..Interior areas outside of the Winter Weather Advisory could see a coating to 2″ of snow with a period of slick travel Tuesday night into early Wednesday Morning. Coastal areas will see mostly rain with little to no snow accumulation with wind gusts of 40-45 MPH and isolated higher wind gusts possible. Rainfall amounts of 1-2″ with isolated higher amounts are also 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. An initial Amateur Radio Net Schedule for locations in the Winter Storm Warning area are posed in this update below. 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 has been reduced since the last update. The solution is slightly warmer but still warning criteria snowfall is expected in the Winter Storm Warning area and reports of snowfall measurements and changeover in precipitation type will be important during the event for any forecast changes and verification of current conditions.
2.) There is no high pressure to the north that would aid in any storm system to bring down cold air but the storm will have some dynamics to keep interior areas particularly at higher elevations as mostly snow. Lower elevations will see lesser accumulations and some mix possible as highlighted in the configuration of the Winter Storm Warning and Winter Weather Advisory areas.
3.) There will be an elevation component to this storm where higher elevations will likely have heavier snow than lower elevations even in the interior. Also, temperatures are expected to be marginally near or just above freezing but where precipitation falls as heavy wet snow, this will result in isolated to scattered pockets of tree and wire damage and 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 with wind gusts of 40-45 MPH with isolated higher gusts possible. Heavy rainfall is also likely in this area with 1-2″ and isolated higher amounts possible.
