Storm Coordination Message #1 – Thursday Night 12/23/21-Friday Morning 12/24/21 Light Snow Event/Late Friday Night 12/24/21-Christmas Day Light Icing Potential

Hello to all…

..Merry Christmas, Happy New Year, Happy Holidays to all SKYWARN Spotters and Amateur Radio Operators..

..A very light snow event overnight Thursday into Friday Morning may allow for a snow accumulation of a Coating to 2″ with the 1-2″ amounts most likely over interior locations and the higher terrain of Western and Central Massachusetts. This could cause a few slick spots on area roadways. While not a significant issue, if this snow stays on the ground and remains at a 1″ or greater level on Christmas Day at 7 AM, it would qualify as a “White Christmas” in those portions of Southern New England..
..The last White Christmas in much of the area was in 2009 where there was 1″ or more of snow on the ground in places such as Boston and Providence. In 2017, areas had snowfall on that day from a departing storm system but for many locations it was after 7 AM so by the technical definition, it was not defined as a “White Christmas” in Southern New England..
..Another storm system late Friday Night into Christmas Day could result in a period of freezing rain and icing conditions in portions of Southern New England in the morning changing to rain in many locations as the day wears on. This will bear watching for travel concerns during this period and will be detailed in future coordination messages..
..SKYWARN Self-Activation will monitor for any snowfall reports Christmas Eve Morning and then icing conditions late Friday Night into Christmas Day morning. Below is the NWS Boston/Norton Area Forecast Discussion and Snowfall Maps..
