Blizzard/Storm Coordination Message #3 – Thursday 2/9/17 Major Winter Storm/Blizzard Potential
Hello to all…
..After a mild spring-like day Wednesday, conditions will get colder and a coastal storm will organize bringing a significant snowfall for Southern New England with strong to damaging winds along the coast and in Eastern New England and a period of blizzard conditions for Eastern Plymouth County and Cape Cod and the Islands and near blizzard conditions in portions of Eastern New England early Thursday Morning through Thursday Evening..
..A Blizzard Warning is now in effect from 9 AM to 8 PM Thursday for Cape Cod and the Islands including Block Island Rhode Island and Eastern Plymouth County Massachusetts for 8-14″ of snow with isolated higher amounts or a band of higher amounts of 14-18″ of snow except on Nantucket where 6-12″ of snow is expected. In the Blizzard Warning area, sustained winds of 20-40 MPH with wind gusts of 50-60 MPH. With the heavy snowfall and strong to damaging winds, this will have the potential to create blizzard conditions and isolated to scattered pockets of tree and wire damage and isolated to scattered power outages..
..A Winter Storm Warning is now in effect from 4 AM Thursday Morning to 8 PM Thursday Evening for Northern Connecticut, Franklin, Hampshire, Hampden, Worcester and Northern Middlesex Counties of Massachusetts for 7-14″ of snow with isolated higher amounts and wind gusts in the 20-35 MPH range..
..A Winter Storm Warning is now in effect from 6 AM Thursday Morning through 8 PM Thursday Night for all of Rhode Island and Eastern Massachusetts not covered by the blizzard warning for 8-14″ of snow with isolated higher amounts or a band of higher amounts of 14-18″ possible and sustained winds of 10-20 MPH with higher sustained winds closer to the coast of 20-30 MPH and wind gusts in the 40-50 MPH range with the higher gusts at the coast. The winds and snowfall may cause isolated pockets of tree and wire damage and isolated power outages along with considerable blowing and drifting snow and near blizzard conditions likely..
..A Coastal Flood Advisory is in effect from 8 AM-1 PM Thursday for East Coastal Massachusetts including Cape Cod and the Islands for minor coastal flooding of shore roads at the time of high tide and potentially extending a couple hours after high tide. Minor splashover could occur at the Thursday Evening high tide cycle…
..SKYWARN Activation with Ops at NWS Taunton will likely commence no later than 6 AM Thursday Morning and last through Thursday Evening..
After a mild spring-like day will occur Wednesday, colder air will be entering the region Wednesday Night. As conditions get colder, a coastal storm will develop and bring a widespread significant snowfall to the region. The headlines depict the current thinking in terms of snowfall amounts and strong to damaging winds in Eastern New England and especially along the coast line including blizzard conditions for Eastern Plymouth County Massachusetts and Cape Cod and the Islands and Block Island where a Blizzard Warning is in effect. Near blizzard conditions are likely in eastern parts of the Winter Storm Warning area especially near the coast and Southeast Massachusetts in South Coastal Rhode Island. Heavier bands of snow are likely and some delineation of those areas are noted. Also, more of a widespread minor coastal flood event has resulted in a coastal flood advisory for East Coastal Massachusetts and Cape Cod and the Islands for the Thursday Morning high tide cycle. Key factors that will determine possible heavier bands of snow and stronger winds and extent of minor coastal flooding and damage from snow and strong winds are as follows:
1.) As stated previously, this will be a coastal storm and the track of the storm will determine where the heaviest snow and possibly a band or two of heavier snow beyond the current ranges will occur within the NWS Taunton coverage area. It will also determine where a wetter snow may occur which coupled with strong winds could result in isolated tree and wire damage and isolated power outages. At this time, the consistency of the snow is expected to start as a wet snow and then get drier as colder air continues to move into the region. Since the last coordination message, heavier snowfall on Nantucket is looking more likely and that along with strong to damaging winds has resulted in a Blizzard Warning being issued for Nantucket along with the other islands, Cape Cod, and Eastern Plymouth County.
2.) There now appears to be the potential for a bigger build up of seas or waves for a bit more of a widespread minor coastal flood event resulting in a Coastal Flood Advisory for East Coastal Massachusetts, Cape Cod and the Islands for the Thursday Morning high tide cycle. Shore road flooding is the biggest threat for coastal flooding Thursday Morning. More minor splashover and isolated coastal flooding is expected for the Thursday Evening high tide cycle as winds turn more offshore by that time.
3.) The track and intensity of the storm and the pressure gradient has meant a bump up in the strength of the winds over Coastal areas of Southern New England and extending into Southeast New England.
SKYWARN Activation with Ops at NWS Taunton will likely commence no later than 6 AM Thursday Morning and last through Thursday Evening. This will be the last coordination message for this storm system unless time allows and a significant change to the situation occurs.
