Forecast: Afternoon Storm Will Bring Some Rain, Sleet Or Snow To Boston

A chilly but dry start to today means there won't be any weather issues during your morning commute.

The morning will be sunny, but clouds will increase as the day goes on. Eventually, a period of snow, sleet and freezing drizzle will slicken up the roads, but it might be just late enough that some of you are already home.

A weak and fast-moving weather system will bring a shot of precipitation into the area later this afternoon and evening. The precipitation will come in the form of a wintry mix or even just rain. As the precipitation falls harder, it appears there will be a burst of snow or sleet. It looks like a mess will move in between 4 and 8 p.m.

I am not expecting much accumulation at all from this system, something on the order of a coating to 2 inches from south to north. I did put 3 inches on the map just in case some areas ends up with slightly more.

In Boston, road crews will likely just need to sand the roads, rather than plow them. But plows will likely need to be out to treat roads further north and west of Route 128 and the Mass Pike.

Roads are much warmer than they were during last week’s weather system. The snow and wintry mix will end overnight and leave us with a cold and raw day on Wednesday. The morning commute will be slow, especially on side streets.

A second weather system brings rain and wind back on Thursday. Winds during the day could gust over 50 miles per hour with scattered power outages and possible street flooding from heavy rain. Drier weather returns to end the work week.
