Storm Coordination Message #2 – Thursday 2/18/21-Friday 2/19/21 – Moderate Snowstorm Potential

Hello to all…

..Moderate plowable snowfall expected in Southern New England Thursday into Friday..
..A Winter Storm Watch remains in effect from Thursday Morning to Friday Evening for the entire NWS Boston/Norton Coverage Area except for Cape Cod and the Islands for 4-8″ of snow. The potential for any icing or changeover in any of the Winter Storm Watch area is less at this time so the Watch area is expected to receive all snow at this time. Portions or all of Cape Cod and perhaps even the islands may also no longer see a mix of precipitation depending on model trends and this will be monitored..
..SKYWARN Self-Activation with Amateur Radio Call Up Nets are likely particularly Thursday Night through Friday. Another coordination message will be posted by 1100 PM. Below is the NWS Boston/Norton Winter Storm Watch Statement, Area Forecast Discussion, Enhanced Hazardous Weather Outlook and the Snow and Ice maps..

Storm Coordination Message #2 – Monday Night 2/15/21-Tuesday Evening 2/16/21 Icing Potential

Hello to all…

..Potential exists for significant icing across portions of interior Southern New England. Some models have trended a bit warmer but some models have colder conditions and the highest risk area for icing that could be damaging is across the east slopes of the Berkshires and Northern Massachusetts in Franklin, Northern Worcester and Northern Middlesex Counties of Massachusetts. Also, the higher terrain of Northwest Hartford County CT could also see higher levels of icing that could cause pockets of icing damage..
..A Winter Weather Advisory is now in effect from 7 PM Monday Evening to 6 PM Tuesday Evening for Franklin, Worcester, Northern Middlesex, Western Hampshire and Western Hampden Counties of Massachusetts for up to 1″ of snow and sleet and 0.10″-0.30″ of icing with isolated higher icing amounts. This amount of icing will result in hazardous road conditions and isolated pockets of tree, wire damage and power outages. If ice amounts near or around 0.50″ occur, tree, wire damage and power outages would be more widespread..
..A Winter Weather Advisory is now in effect from 7 PM Monday Evening to 10 AM Tuesday Morning for Northern Connecticut, Eastern Hampden and Eastern Hampshire Counties of Massachusetts for up to 1″ of snow and up to 0.20″ of icing with isolated higher amounts..
..A Winter Weather Advisory is now in effect from 7 PM Monday Evening to 10 AM Tuesday Morning for Central Middlesex, Essex, Norfolk, Suffolk, North-Central Bristol, North-Central Plymouth Counties of Massachusetts, Providence, Kent, Bristol and Washington Counties of Rhode Island for up to 1″ of snow and light icing glaze..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely across the Winter Weather Advisory area particularly for Western, Central and Northeast Massachusetts and Northwest Connecticut for later Monday Evening into Tuesday Afternoon to monitor precipitation type, ice accretion levels and any icing damage..

A storm system will move its way up from the Southeast United States into the Northeast. Precipitation will be spotty and light Monday Afternoon and become steadier and heavier Monday Night into Tuesday Morning. The potential for a more potent ice storm seems to be less as some reliable model guidance warms things more quickly particularly in Connecticut, Rhode Island and Southeast and South-Central Massachusetts but other model guidance is colder particularly across Western and Northern Massachusetts and Northwest Connecticut. The headlines depict the current thinking. Key factors include:

1.) How deep the column of cold air will be to determine if precipitation falls as freezing rain, sleet, snow or rain.
2.) The track of the storm as that will dictate the deepness of the cold air across the area including how much snow, sleet, freezing rain or rain falls in a given area and what areas could see the most ice accretion. Subtle differences in storm track of as little as 30-50 miles could significantly impact the areas that could see significant icing versus more snow and sleet or more rain. A bit of a warmer solution is predicted but areas of Western and Northern Massachusetts and Northwest Connecticut will bear close monitoring for a bit higher icing amounts and if that were to occur more significant icing damage could occur. Spotter reports will be important to determine that potential particularly as we get into early Tuesday Morning.

For measuring ice accretion, please note the following graphics on how to properly measure ice on a flat surface or on an object such as tree, tree branch or other similar object as denoted by the SKYWARN training material:

Storm Coordination Message #1 – Monday Night 2/15/21-Tuesday Evening 2/16/21 Ice Storm Potential

Hello to all…

..Potential exists for significant icing across portions of interior Southern New England. If widespread icing of around 0.50″ can occur, it will have the potential to cause scattered to numerous pockets of tree, power line damage and power outages..
..A Winter Storm Watch is now in effect from Monday Afternoon through Tuesday Evening for Northern Connecticut, Northwest Providence, Western Kent Counties of Rhode Island, Franklin, Hampshire, Hampden, Worcester, North-Central Middlesex, Western Essex and Western Norfolk Counties of Massachusetts for up to 3″ of snow with the highest snow totals in Northwest Massachusetts and up to 050″ of ice across the watch area. If 0.50″ of ice is realized, pockets of tree, wire damage and power outages are likely..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely across the Winter Storm Watch area particularly later Monday Evening into Tuesday Afternoon to monitor precipitation type, ice accretion levels and any icing damage..

Storm Coordination Message #4 – Sunday 2/7/21 Coastal Storm Hazards

Hello to all…

..Coastal Storm on track to affect much of Southern New England late Sunday Morning through late Sunday Evening with a plowable to heavy snowfall. Track of system remains a bit lower confidence than normal at this time range thought model ensembles have a better a handle on this coastal storm system. Some changes to Winter Storm headlines have been made based on the latest guidance including lesser snow amounts in northwest areas of Southern New England and higher amounts of snow on Nantucket..
..A Winter Storm Warning remains in effect from through 1 AM Monday for Bristol, Plymouth and Barnstable Counties of Massachusetts and all of Rhode Island except for Block Island for 5-9″ of snow with isolated higher amounts and wind gusts particularly along the coast of 40-50 MPH. The Outer Cape could see lesser amounts of 2-5″. The snow is likely to be heavy and wet particularly in coastal areas and Southeast New England and the wet snow and wind gusts may result in isolated to scattered pockets of tree and wire damage and power outages..
..A Winter Weather Advisory is now in effect through 1 AM Monday for Tolland and Windham Counties of Connecticut, Worcester, Essex, Middlesex, Suffolk and Norfolk Counties for 3-6″ of snow with isolated higher amounts in the southern and eastern portions of the advisory area. The Winter Storm Warning for this area has been cancelled..
..A Winter Weather Advisory remains in effect through 1 AM Monday for Block Island RI, Marthas Vineyard and Nantucket for 2-6″ of snow and wind gusts to 40-50 MPH. If snow totals of 3″ or more occur given the snow being heavy and wet, the potential would exist for isolated pockets of tree and wire damage and power outages..
..A Winter Weather Advisory remains in effect through 1 PM Monday for Franklin, Hampshire, and Hampden Counties of Massachusetts and Hartford County CT for 2-5″ of snow..
..A Wind Advisory is now in effect for Nantucket Island from 2-10 PM Sunday for Nantucket Island for sustained winds of 20-30 MPH and gusts to 50 MPH. The winds and any wet snow accumulation could result in isolated pockets of tree and wire damage and isolated power outages..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely across much of Southern New England for this storm event early Sunday Afternoon through Sunday Night..

A coastal storm is taking aim on Southern New England for Sunday Morning through late Sunday Night. Model guidance is coming into gradual agreement on the track, speed and intensity of the storm but uncertainty is higher than normal for a storm system that will start impacting the area in just few hours. The headlines depict the current thinking. Key factors include:

1.) There remains some spread in the guidance a bit larger than normal regarding the northwest cutoff in precipitation over the region. At this time, a plowable snowfall is expected across much of Southern New England but a bit less than forecast so snowfall amounts have been lowered in interior Southern New England north and west of I-95.
2.) The intensity of the storm will dictate any wind issues in addition to heavy snowfall across eastern and southeastern New England. Also, temperatures will be near freezing in Southeastern and East Coastal New England which could result in a heavier wetter snow which coupled with wind gusts of 40-50 MPH could cause isolated pockets of tree and wire damage and power outages.
3.) Some models bring some mixing to some coastal areas particularly the Outer Cape and the islands and precipitation could initially start as rain before quickly changing to snow as evaporational and dynamic cooling take place. Models are a little more offshore with the storm which means a bit more colder air so less mixing may occur here. Amounts on Nantucket Island were adjusted upward and while the other island and the Outer Cape have the same snow amounts forecasted as last night, there could be higher amounts here if the trend towards less mixing verifies. This is another tough part of the forecast as just a slight shift in track or precipitation falling heavy enough to remain accumulating snow may allow for higher amounts over these areas.
4.) The storm will be fast moving starting early to mid morning Sunday and finishing by mid-evening Sunday.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely across much of Southern New England for this storm event Sunday Morning to Sunday Night. This will be the last coordination message for this storm system as we shift into operations mode.
