The on again, off again snow event for Tuesday and Tuesday night is on again, and it looks like it will bring a borderline plowable snow to some places in Rhode Island and Southeastern Massachusetts. Snow or a mix of rain and snow should begin by late Tuesday morning, and it will likely change to all snow by late in the day then continue through most of the night.
The temperature will be above freezing during the afternoon, so any accumulation on the road is unlikely through late in the day. Once the sun sets, however, there is a better chance of the snow starting to stick on untreated surfaces. The evening commute could be slowed by some light to moderate snow and temperatures in the low 30s. The best chance of accumulating snow is Tuesday evening as the storm intensifies while passing southeast of Nantucket. The steadiest precipitation will be in Southeastern Massachusetts Tuesday night, but all of Rhode Island will also see snow until late at night. The temperature may fall into the 20s by late Tuesday night, leading to some slick untreated roads and sidewalks early Wednesday.
This will not be a major storm, but some areas could pick up 3-4″ of snow by early Wednesday morning. The best chance of seeing those amounts is in interior SE MA and in RI away from the immediate coast.
Dry and chilly weather is likely from midday Wednesday through Friday.
