Snow Squall Coordination Message #2 – Saturday Afternoon/Evening 2/19/22 Snow Squall Potential

Hello to all…

..A line of snow squalls associated with an arctic cold front will sweep through the region between about 2-8 PM Saturday from west to east. They will bring briefly heavy snow, strong wind gusts potentially up to 35-40 MPH and a quick coating to 1″ of snow with isolated amounts of 2″ but in the timeframe of an hour or less. These type of snow squall situations with an arctic cold front can cause rapidly lowered visibility with a brief period of whiteout conditions, icy roads and the potential for car accidents due to rapidly changing road conditions. Spotter reports for Snow Squalls will be very helpful for this situation..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely similar to a summer time thunderstorm situation where nets will be brought up as the line of snow squalls move through the area on Saturday. The traditional reporting criteria of a final snowfall amount, thundersnow, measured wind gusts 40 MPH or greater and any wind damage will be helpful and in addition to those reports, per the snow squall reporting criteria, visibility of 1/4 mile or less and where possible pictures and/or videos of to show those conditions and any reports of accidents during or shortly after the snow squall has passed..
..This will be the last coordination message as we shift into operations mode. Pics/videos of the snow squalls can be sent via our WX1BOX Facebook/Twitter feeds or to the email address Below is the NWS Boston/Norton Area Forecast Discussion and the Storm Prediction Center (SPC) Mesoscale Convective Discussion (MCD)..
