Storm Coordination Message #5 – Wednesday 11/26/14-Thanksgiving Morning 11/27/14 Coastal Storm

Hello to all..

..Coastal Storm will affect the region Wednesday into Thanksgiving Morning with strong to damaging winds along the coast line and the potential for heavy snowfall in the interior and heavy rainfall possibly changing to snow before ending across the coastal plain north and west of the Cape Cod Canal..
..A Winter Storm Warning remains in effect Through 7 AM Thursday Morning for Southern New Hampshire and Franklin, Hampshire, Hampden, Northern Worcester and Northern Middlesex Counties of Massachusetts for 8-12″ of snow with isolated higher amounts possible..
..A Winter Storm Warning is now in effect through 7 AM Thursday Morning for Northern Connecticut, Central Middlesex, Western Essex and Southern Worcester Counties of Massachusetts for 4-8″ of snow with isolated higher amounts possible and a trace of ice..
..A Winter Weather Advisory is now in effect from 7 AM Wednesday Morning through 7 AM Thursday Morning for Eastern Essex, Norfolk, Southeast Middlesex, and Suffolk Counties of Massachusetts and Providence and Kent Counties of Rhode Island for 1-3″ of slushy snow accumulation. This is the area with the lowest confidence in terms of snowfall amounts but current trends with a closer storm track has reduced snowfall amounts in this area..
..A Wind Advisory is now in effect for Eastern Plymouth County Massachusetts and Cape Cod and the Islands from 2 PM Wednesday Afternoon through 3 AM Thursday Morning for sustained winds 25-35 MPH with gusts to 50 MPH likely to possibly 55 MPH. A Wind Advisory is now in effect from 2 PM Wednesday Afternoon through 3 AM Wednesday Morning for South Coastal Massachusetts and Rhode Island including Bristol County Rhode Island for sustained winds of 25-35 MPH with gusts to 50 MPH likely. Areas north and west of the Wind Advisory area in Southeast New England will likely see wind gusts to 40 MPH. These winds have the potential to cause isolated pockets of tree and wire damage and power outages..
..Locations in the Winter Storm Warning area and possibly the Winter Weather Advisory area will be monitored closely not only for the potential of significant travel impacts (worst in the mid-afternoon/evening) but also for the potential of isolated tree and wire damage due to the snow likely being of a heavy and wet consistency. Areas outside of the Winter Storm Warning/Winter Weather Advisory issuance north and west of the Cape Cod Canal may see heavy rainfall change to a period of snow or mixed precipitation before the storm ends Thursday Morning with little to no accumulation..
..Coastal flooding is currently not expected due to lower astronomical tides and the short duration of the strong winds at the coast. Heavy rainfall in Southeast New England may lead to urban and poor drainage flooding in the typical locations..
..SKYWARN Activation with Ops at NWS Taunton will commence around 9 AM Wednesday lasting through late Wednesday Night for this coastal storm as the onset of precipitation is earlier than previously expected..
..Storm related pictures/video of snowfall and damage can be sent to our Facebook and Twitter feeds, as a reply to this message or to the pics@nsrdio.org email address with credit given to the spotter and the pictures and video shared with the media and emergency management unless otherwise indicated..

A coastal storm will affect one of the busiest travel days of the year with heavy snowfall in the interior and heavy rainfall changing to snow over portions of Eastern New England north and west of the Cape Cod Canal. The headlines of the coordination message depict the current threats and have been tweaked slightly for a slightly warmer solution and a closer to Nantucket Island storm track as there has been a trend towards this solution in the last few model runs. This has meant slightly lesser amounts of snow in southern and eastern areas of the Winter Storm Warning area but higher snowfall amounts in the western parts of the Winter Storm Warning area and much lower snow amounts in the Winter Weather Advisory area. No changes to the winter headlines given the current track. In addition to potential for significant travel impacts in the Winter Storm Watch/Warning areas, the potential for isolated tree and wire damage due to the snow being heavy and wet will also need to be monitored.

A Wind Advisory continues for Eastern Plymouth County and Cape Cod and the Islands from 2 PM Wednesday Afternoon through 3 AM Thursday Morning. This is a higher end wind advisory with wind gusts to 50 or possibly even 55 MPH possible and there is a chance of even higher wind gusts. The Wind Advisory is expanded to include South Coastal Massachusetts and Rhode Island including Bristol County RI for the same timeframe. Areas in Southeast New England just outside the Wind Advisory area could see wind gusts around 40 MPH later this afternoon and tonight. These winds may cause isolated pockets of tree and wire damage and power outages in the coastal plain.  Coastal flooding is currently not expected due to lower astronomical tides and the short duration of the strong winds at the coast. Heavy rainfall in Southeast New England may lead to urban and poor drainage flooding in the typical locations.

Precipitation is now moving into the region. Small deviations in track, speed, intensity of the system and the amount of cold air that is drawn into the system can still cause deviations to the current thinking and forecast particularly in the Boston to Providence corridor and eastern areas of the Winter Storm Warnings currently in place but the forecast based on current trends seems on track at this time.

Precipitation type and changeover information and where frozen precipitation is accumulating (paved surfaces and grassy surfaces or just grassy surfaces) will be very critical to this storm in addition to snow accumulation information. Also, if your elevation is known, that will also be helpful to draw any delineation that may be based on elevation.

SKYWARN Activation with Ops at NWS Taunton will commence around 9 AM Wednesday Morning lasting through late Wednesday Evening. This will be the last coordination message issued on this coastal storm. Storm related pictures/video of snowfall and damage can be sent to our Facebook and Twitter feeds, as a reply to this message or to the pics@nsrdio.org email address with credit given to the spotter and the pictures and video shared with the media and emergency management unless otherwise indicated.
