Storm Coordination Message #1 – Wednesday 12/7 to Thursday AM 12/8 Storm Event
Hello to all..
..Strong and Quick Hitting Coastal Storm will bring Heavy Rain, a brief period of heavy snow to the far northwest interior and strong winds to portions of the higher terrain and coastal locations Wednesday Night through daybreak Thursday Morning..
..A Winter Weather Advisory is in effect from Midnight through 6 AM Thursday for Cheshire and Western-Central Hillsborough Counties of New Hampshire and Franklin, Western Hampshire, Western Hampden, Northern Worcester and Northern Middlesex Counties of Massachusets for 3-5″ of snow with the highest amounts in Cheshire County NH and in the higher elevations near the east slopes of the Berkshires..
..A Wind Advisory is in effect from 3 to 10 AM Thursday for Cape Cod and the Islands for sustained winds 25-35 MPH with gusts to 50 MPH. These winds may be sufficient to cause isolated pockets of tree and wire damage in the advisory area..
..Heavy Rainfall of 1.5-2.5 inches of rain may cause minor urban and poor drainage flooding during the day and tonight over portions of Southern New England resulting in flood advisory issuances..
..SKYWARN Self-Activation will be utilized to monitor rainfall totals, urban/poor draiange flood reports, snowfall totals, changeover from rain to snow in the interior and strong winds over the region. On Thursday Morning, the New England reflector system *NEW-ENG* node: 9123/IRLP 9123 system and a check of the Paxton and Pack Monadnock Repeaters will be done to collect snowfall totals from the advisory between 6-8 AM as precipitation should be ending rapidly during this timeframe. If required other SKYWARN repeaters will be checked for rain, flood and wind information..
At 740 AM, Doppler Radar shows a large area of precipitation affecting portions of Southern New England with heavier rain just offshore of the coast and affecting the islands and heavy rainfall in the Central and Eastern Pennsylvania area that will move northeast into Southern New England later today. This rain also extend back into West Virginia. Much of today will see rain heavy at times extending into tonight. The rain may cause some urban and poor draiange flooding and result in some urban flood advisory issuances over areas that receive heaviest rainfall. Rainfall totals of 1.5 to 2.5″ are expected across the area especially along and south of the Mass. Pike. As the low spins up at the coast, this will draw down colder air into northwest portions of the area bringing a changeover to wet snow which will be heavy at times but ending around daybreak and near or just before the morning commute starts. A Winter Weather Advisory is in effect from Midnight to 6 AM for Cheshire, West-Central Hillsborough Counties of New Hampshire, and Franklin, Western Hampshire, Western Hampden, Northern Worcester and Northern Middlesex Counties of Massachusetts for 3-5″ of snow with the highest amounts in Cheshire County NH and in the higher elevations of northwest Massachusetts.
Strong winds will affect coastal areas and to a certain extent in the higher terrain locations of interior Massachusetts. A Wind Advisory is in effect for Cape Cod and the Islands from 3 to 10 AM Thursday for sustained winds 25-35 MPH with gusts to 50 MPH probable. These winds may be sufficient to cause some isolated pockets of tree and wire damage. Interior high terrain locations will also need to be monitored to see if winds become strong enough to hit advisory levels or strong winds combined with 3 to 5 inches of potentially wet snow may cause isolated pockets of tree and wire damage in those locations as well.
SKYWARN Self-Activation will be utilized to monitor this storm system. Ops at NWS Taunton don’t appear to be necessary but that will be monitored. A particular timeframe that will be monitored will be between the 6 to 8 AM Thursday Morning timeframe to collect rain and snowfall totals of criteria as well as any wind measurements or damage reports of criteria. Most of the snow is expected to fall during the overnight period while heavy rainfall can be expected Wednesday Afternoon and Night into early Thursday Morning. Precipitation is expected to stop near or just prior the start of the morning commute.
