Snow Squall Strong Wind and Wind Chill/Bitter Cold Coordination Message #1 – Wednesday 11/21/18-Thanksgiving Day 11/22/18 – Snow Squall, Strong Wind, Bitter Cold and Wind Chill Potential

Hello to all…

..On behalf of the entire NWS Boston/Norton staff and the WX1BOX Amateur Radio Team, Happy Thanksgiving to all SKYWARN Spotters and Amateur Radio Operators! We are forever grateful for all the reports that help the severe weather warning process and provide the ground truth of weather conditions actually happening on the ground during severe weather events..
..Localized snow squalls are possible today in Southern New England particularly between 3 and 8 PM. While the greatest risk for snow squalls is in Northern New England, there is a risk for these snow squalls in Southern New England with the greatest risk in Western and Northern Massachusetts nearest the more favorable environment in Northern New England though any localized area in Southern New England may see a snow squall..
..A Wind Chill Advisory is now in effect from 4-10 AM Thanksgiving Morning for Western Franklin, Western Hampshire and Western Hampden counties for wind chills as low as 15 below zero. Areas out side of the Wind Chill Advisory could see wind chills 5 above to 10 below zero overnight Wednesday into Thanksgiving morning and early afternoon making for bitterly cold conditions particularly for this time of year. Anyone doing outdoor activities Wednesday Night and Thursday should dress warmly and in layers over this timeframe..
..Winds are expected to stay below wind advisory criteria but are expected to gust in the 35-45 MPH range causing bitter cold wind chills. A pocket or two of isolated tree and wire damage may occur with these winds..
..Additional Snow squalls in the form of ocean effect are possible in the Outer Cape as very cold winds over warm ocean waters provide some enhancement tonight and Thanksgiving Day. This is expected to result right now in a coating-1 inch of snow but will be monitored in future updates..
..SKYWARN Self-Activation will monitor the strong winds and snow squall activity for Wednesday Afternoon and Wednesday Night and the strong winds through Thursday Morning. This will likely be the only coordination message on the snow squall, strong wind and bitter cold temperatures for the Thanksgiving period unless a significant upgrade occurs and time allows for an update.
