The snow that made a mess of Tuesday morning's commute has turned to sleet and freezing rain, which made for a rough evening commute as well.
Snow will continue to fall, and accumulate, during the evening commute in parts of northern Vermont, northern New Hampshire, and much of Maine. That’s where air temperatures will remain well below freezing.
In parts of southern New Hampshire, southern Maine, and areas north and west of Boston in Massachusetts, temperatures will be falling back below freezing. That means anything that melted during the day or fell as rain will re-freeze and create very slick travel during the evening drive.
Some freezing drizzle is also likely, adding even more slick areas. Expect similar conditions in parts of northern Connecticut.
Spotty showers will turn to drizzle south and east of Boston, but temperatures there will remain a bit above freezing during the evening commute.
