Clever commute will put you "in the know" no matter what amount of "snow" there is!
While the weather folks can't come to a consensus on how much we will get and when, it appears certain that a winter storm is coming to our area late Tuesday night through Wednesday.
If you are commuting into Boston, you should consider joining Clever Commute. In my experience commuting via the Franklin Line, Clever Commute beat the MBTA alerts most of the time.
