From Meterologists Michelle Muscatello and Pete Mangione.
While the RADAR was showing snow for a while, the dry air was eating it up. Now some of the snow is making it to the ground. This trend will continue overnight.
While it’s not a major storm, by any means, it will be enough snow to make roads slick and travel slow overnight into early Thursday morning. In response, a “Winter Weather Advisory” remains in effect for all of RI and southeastern MA until 7AM Thursday.
A general 2-4″ of snow is expected for our area. There may be a little less along the immediate SW corner of RI (Westerly, Charlestown, Narragansett) and a little around Boston and Wocester.
TIMING THE SNOW:
The bulk of the accumulations will be between 11PM and 4AM. Lighter snow showers will taper off through the morning commute, with little to no additional accumulations after 5AM.
Unlike so many systems that have come through this winter with an icy mix of precipitation, this will be an ALL SNOW event. Air and pavement temperatures will be well below freezing, so it wont take long for snow to start sticking to untreated surfaces making for slick travel conditions.
The good news is the snow will be dry, fluffy and easy to clean up. A brush, leaf blower or quick pass with the snow-blower will sweep it away. That should limit the impacts to the school day and morning commute, with improving conditions after 5AM.
