Storm Coordination Message #2 – Sunday Evening 12/11/16-Monday After 12/12/16 Winter Storm Potential

Hello to all…

..Plowable snowfall expected for much of interior Southern New England Sunday Night through midday Monday with a fairly rapid snow to ice to rain transition along coastal areas from the Boston to Providence corridor south and east and a slower transition of snow to ice to rain across Northern Connecticut, Northwest Rhode Island and Northeast Massachusetts to near the I-495 corridor with mostly snow and ice north of the Mass Pike and west of I-495. The Monday Morning commute will have wintry impacts particularly from the I-495 corridor north and west and from just south of the Massachusetts/Connecticut/Rhode Island border and points north..
..A Winter Weather Advisory is now in effect from 7 PM this Sunday Evening to 1 PM Monday for Northern Connecticut, Northwest Providence County Rhode Island and from Essex and Southeast Middlesex Counties westward to the Berkshires. Total snowfall of 3-6″ is expected along and north of the Mass Pike and along and west of I-495 with up to one tenth of an inch ice near I-495 and the Mass Pike. Total snowfall of 2-4″ is expected for much of Northern Connecticut, Northwest Rhode Island and interior Northeast Massachusetts between the I-95 and I-495 corridor with a tenth of an inch of ice. A coating to 2″ of snow is expected along and south and east of I-95 from the Boston to Providence corridor south and east. Model solutions have varied on how long cold air will hold in the region and this may result in snow accumulation adjustments and possibly ice accumulation adjustments..
..SKYWARN Self-Activation will monitor for snowfall and icing reports and changeover in precipitation type reports for this storm event. Some Amateur Radio call-up nets on local SKYWARN repeaters are possible later Sunday Evening or Monday Morning depending on storm timing and snowfall amounts..

The first widespread snowfall of the season is expected across much of Southern New England and especially interior locations of Southern New England. The headlines of this coordination message depict the current thinking and has not changed. A Winter Weather Advisory is now in effect from 7 PM this Sunday Evening to 1 PM Monday for Northern Connecticut, Northwest Providence County Rhode Island and from Essex and Southeast Middlesex Counties westward to the Berkshires. Key items for this storm continue to include:

1.) Timing of the onset of the storm. It will initially be cold and if snow is able to reach the ground Sunday Evening, it will be a light fluffier snow which could allow for more accumulation. If it is too dry, it may take time for thing to moisten up to allow snow to reach the ground.
2.) How long the cold air is able to remain entrenched in the region and how deep the cold air will be. This will determine if snow is able to last longer particularly in interior locations and how much any ice accumulation could be in the area. It is noted that temperatures were colder than expected this morning and that will need to be monitored to see how much warming occurs during the day and this could affect snow and ice amounts.
3.) Storm track and how quickly secondary low formation occurs and where it tracks. This could impact the amount of cold air in the region as highlighted in item 2.

SKYWARN Self-Activation will monitor for snowfall and icing reports and changeover in precipitation type reports for this storm event. Some Amateur Radio call-up nets on local SKYWARN repeaters are possible later Sunday Evening or Monday Morning depending on storm timing and snowfall amounts. Another coordination message will be posted by 1000 PM Sunday evening. Below is the NWS Taunton Winter Weather Advisory statement, Hazardous Weather Outlook and Winter Weather Graphics:
