This is not going to be a major storm by any means, with relatively light precipitation amounts, very little wind and no coastal concerns. The timing of the wintry precipitation is the major concern with this event, starting around midnight tonight and continuing through the Monday morning drive.
It will begin as snow for all of Southern New England…just before midnight along the South Coast and just after midnight in the Boston area and points north. The snow will be mainly light, accumulations only a dusting to 2″ for the entire area. Warming at upper levels of the atmosphere will begin to work from south to north early Monday morning changing the snow over to a mix of sleet, freezing rain and eventually plain rain. This will happen first along the South Coast and in southeastern Massachusetts…here there will just be a brief period of ice before the change to rain around dawn.
In Boston the change will likely occur between 6am and 8am, a short period of an icy mix and to all rain by the tail end of the commute. Areas north and west of Boston will take the longest to warm above freezing at all levels. Snow will change to sleet and freezing rain mid to late morning and eventually to plain rain by midday in places like Northern Worcester County and Southern New Hampshire. This is where travel will be trickiest, but again, with relatively light precipitation amounts (well under 0.5″), major issues are not expected.
All of Southern New England gets above 32 degrees by afternoon and the rain will taper by late afternoon. Other than a few rain or snow showers on Tuesday, the rest of the week will be quiet and dry but very cold. Most areas will be near or below freezing from Wednesday through the start of the weekend.
