Storm Coordination Message #3 – Sunday Evening 3/3/19-Monday Morning 3/4/19 Winter Storm Potential

Hello to all…

..Moderate to Major Snowstorm to affect Southern New England tonight through Monday Morning. Latest Models have increased snowfall amounts for much of the area but there does remain uncertainty in the Southeast coastal areas where sleet and/or rain could hold down amounts. If higher snow amounts are realized in interior central and Southeastern New England and coastal Southeast New England, wet snow damage risk would increase..
..A Winter Storm Warning remains in effect from 7 PM Sunday Evening to 10 AM Monday Morning for Northern Connecticut, All of Rhode Island Eastern Hampshire, Hampden, Worcester, Essex, Middlesex, Suffolk, Norfolk and Plymouth Counties of Massachusetts for 5-10″ of snow likely with isolated higher amounts to around 12″ possible in interior portions of the warning area. The southern and eastern parts of the warning area may see a wet snow that could cause isolated to scattered pockets of tree and wire damage and power outages particularly if higher amounts are realized..
..A Winter Weather Advisory remains in effect for Franklin and Western Hampshire Counties of Massachusetts from 7 PM Sunday Evening to 10 AM Monday Morning for 3-6″ of snow..
..A Winter Weather Advisory is now in effect for Barnstable County Massachusetts from 7 PM Sunday Evening to 10 AM Monday Morning for 3-5″ of snow as sleet and rain mix holds down amounts in this area with wind gusts between 35-40 MPH. If less mixing occurs, it would increase snow amounts with isolated pockets of tree and power line damage and power outages possible. Martha’s Vineyard and Nantucket Island are expected to see 2″ or less of snow at this time..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets will monitor for snowfall reports, precipitation type reports and any wet snow damage reports..

Another winter storm will affect the region tonight into Monday Morning. The headlines depict the current expectations which have been increased a little since the last message which has necessitated this update. As people have probably seen over the last few storms, models have struggled with the pattern and with marginal temperatures causing mixing with sleet and rain, this has affected snow totals in some areas in past storm events, however, for this storm, the trend in the models between the prior message and this message has been for a stronger storm solution with heavier snow and a storm track favorable for what is outlined about. Key factors for this specific storm remain as follows:

1.) How much rain and sleet mixes in with the snow in the southeast portions of the Winter Storm Warning at the coastline. If that mix occurs, it could hold snow amounts down. If it falls mostly as snow, it could be a heavy wet snow which would increase the potential for isolated to scattered pockets of tree and wire damage and power outages.
2.) The storm track, speed and intensification process of the storm will be another factor. If the storm track is a bit more southeast or intensification occurs later in time or further offshore, snow amounts will be on the lower end of the ranges. If the storm track holds to the same current projection or gets a bit closer and the intensification occurs a little more rapidly closer to our region, it would support the higher end of the snow total ranges particularly in the interior portions of the Winter Storm Warning are with the isolated higher amounts being a bit more widespread. As of this update, the track near the 40 North/70 West benchmark and more intensification earlier is leading to higher snowfall rates per hour which means a stronger storm solution that will bear watching for both higher end snow amounts as depicted as well as a potential greater threat for wet snow damage.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets will monitor for snowfall reports, precipitation type reports and any wet snow damage reports. This will be the last coordination message as we shift into operations mode.

Storm Coordination Message #1 – Late Friday Night 3/1/19-Saturday Evening 3/2/19 Winter Storm Potential

Hello to all…

..Coastal storm system to bring heavy accumulating wet snow storm to portions of Southern New England late tonight into early Saturday Evening. Confidence in storm solution lower than normal at this time range due to varying model solutions..
..A Winter Storm Warning is now in effect from 1 AM to 7 PM Saturday for Bristol and Plymouth Counties of Massachusetts for heavy wet snow accumulating from 4 to 8″ with isolated higher amounts possible and the heaviest snow between 4 AM and 12 PM Saturday. The heavy wet snow with wind gusts 35-40 MPH may cause isolated pockets of tree and wire damage and isolated power outages..
..A Winter Weather Advisory is now in effect from 1 AM to 7 PM Saturday for Northern Connecticut, All of Rhode Island, Cape Cod, Martha’s Vineyard, Eastern Hampshire, Hampden, Worcester, Norfolk, Suffolk, Essex and Middlesex Counties of Massachusetts for 2-5″ of snow with isolated higher amounts and those isolated higher amounts being most likely in Rhode Island and Eastern Massachusetts and the heaviest snow between 4-10 AM. Cape Cod and Martha’s Vineyard may also see higher snow amounts if no mix with sleet or rain occurs during the storm event. If snow amounts are greater than 4″, isolated pockets of tree and wire damage and power outages are possible particularly coastal areas where there could also be wind gusts between 35-40 MPH..
..Interior areas outside of the Winter Storm Warning and Winter Weather Advisory areas will receive a Coating to 2″ of snow with snow to rain on Nantucket Island..
..Another significant winter storm will affect the region Sunday Night into Monday with heavier snow in the interior and snow mixing with sleet and rain along and southeast of the Boston to Providence corridor. Details on this system will be in future coordination messages..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets will monitor this winter storm potential late Friday Night into early Saturday Evening..

An active weekend of winter weather will affect Southern New England tonight into early Saturday Evening and again late Sunday Afternoon into Monday. This message focuses on the first winter storm for tonight into early Saturday Evening. Additional coordination messages focusing on the late Sunday Afternoon into Monday winter storm will occur after the late Friday night into early Saturday Evening storm is completed. The headlines focus of the coordination message focuses on the late Friday Night into early Saturday Evening storm. Key factors for this storm includes:

1.) Model agreement this close to the storm event is lower than normal. There had been a trend towards a closer to the coast solution which has now trended a little further offshore. Any continued changes in this regard could make snowfall amounts greater in Southern New England and further west with more mixing in Southeast Coastal New England or keep the storm more focused on Southeast New England as currently depicted or even slightly further south and east if the storm tracks a bit more to the east or offshore.
2.) The amount of intensification as the storm swings through the region as well as how quickly it will swing through the area. This will affect snowfall rates per hour and may also be a factor in precipitation type along the south coastal Massachusetts and Rhode Island region. The speed of the system will also affect the duration of the heavier snowfall.
3.) Snow accumulations over 4 inches and especially over 6 inches with wind gusts in the 30-40 MPH range and those strongest wind gusts in East and South Coastal Massachusetts would have the potential to cause isolated pockets of tree and wire damage and isolated power outages. This could be a greater threat if the heavier snow amounts occur and over a more widespread area.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets will monitor this winter storm potential late Friday Night into early Saturday Evening. This will most likely be the only coordination message on this storm event unless time allows for an update and a significant change to the storm scenario occurs.
