Storm Coordination Message #1 – Monday 2/1/21-Tuesday 2/2/21 – Coastal Storm Potential

Hello to all…

..Coastal Storm has the potential to bring significant snow to much of Southern New England with a snow/sleet/freezing rain and rain mixture across Southeast New England, strong to damaging winds in coastal areas and the potential for widespread minor with areas of moderate coastal flooding at the time of high tide across East Coastal Massachusetts, Cape Cod and the Islands..
..A Winter Storm Watch is now in effect for Northern Connecticut, Franklin, Hampshire, Hampden, Worcester, Middlesex, Essex, Suffolk, Norfolk, Northern Bristol Counties of Massachusetts, Providence, Kent, Washington and Bristol Counties of Rhode Island from Monday Morning through Tuesday Afternoon for 6-12″ of snow with isolated higher amounts and wind gusts of 35-40 MPH with isolated higher gusts closest to the coast. The snow will have the potential to be heavy and wet with isolated to scattered pockets of tree and power line damage and power outages possible..
..Areas of Southeast New England will see several inches of snow before a mix to changeover rain and then back to snow before the system pulls away Tuesday Evening..
..Areas of widespread minor with areas of moderate coastal flooding are likely during the time of high tide Monday Night and Tuesday and this could require a Coastal Flood Watch in future forecasts. Flooding of shore roads is potentially likely along with beach erosion and perhaps minor structural coastal flood damage..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets likely Monday into Tuesday for multiple weather hazards including snowfall totals, precipitation changeover, wet snow/wind damage reports and coastal flood road closures and damage reports. Pictures of storm damage can be posted as a reply to this message, via our WX1BOX Facebook and Twitter feeds or via the email address pics@nsradio.org..

A coastal storm will impact Southern New England with a myriad of weather hazards across Southern New England late Monday Morning through Tuesday Afternoon with significant snowfall, strong to damaging winds along and near the coast and the potential for widespread minor with areas of moderate coastal flooding at the time of high tide across East Coastal Massachusetts, Cape Cod and the Islands. The headlines depict the current thinking. Key factors include:

1.) The rain/snow line and coastal front setup. This will depict which areas see the heaviest snow as areas along and north and west of that coastal front will receive the heaviest snow while areas south and east of that line will see a snow to wintry mix to rain changing back to snow before ending.
2.) Models indicate areas of Southern New England particularly nearest to that coastal front that sets up could see a heavy, wet snow that combined with any winds could result in isolated to scattered pockets of tree and wire damage and power outages.
3.) Strong to damaging winds at the coast and the strength of those winds. That will determine the extent of any wind damage and have some impact on the coastal flood potential.
4.) Extent of coastal flooding based on the track, speed and intensity of the storm and the timing of the strongest winds with the high tide cycles. If confidence increases, Coastal Flood Watches will be posted for the next couple of high tide cycles.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets likely Monday into Tuesday for multiple weather hazards including snowfall totals, precipitation changeover, wet snow/wind damage reports and coastal flood road closures and damage reports. Pictures of storm damage can be posted as a reply to this message, via our WX1BOX Facebook and Twitter feeds or via the email address pics@nsradio.org. The next coordination message will be posted at 1030 AM Sunday Morning.
