Good morning everyone,

Here is the latest thinking about the coastal storm which will pass southeast of New England today into early Tuesday. It will bring snow to much of the area this afternoon before a change to rain Monday night. This is expected to be a minor snowfall event, with the exception of the higher elevations of western and central MA, where as much as 8 inches of snow is possible.

NEW:

Northwest Middlesex County changed from a Winter Weather Advisory to a Winter Storm Warning

What/Where/When:

Snow develops from west to east across much of southern New England Monday afternoon, except near the South Coast, Cape Cod, and the Islands where mainly rain is expected.
Snow is expected to be heavy at times late Monday afternoon into evening, especially in the Berkshires and northern Worcester Hills. Heavy snowfall rates could lead to snow-packed roads and difficult travel.
Snow mixes with and changes over to rain from south to north. The higher elevations of northern Worcester County and the Berkshires are expected to remain mostly snow.
The consistency of the snow will be heavy and wet.

Uncertainty:

Snow amounts will be highly elevation-dependent, leading to potentially significant countywide differences in snow totals.

Portions of northwest Hartford County may see 3-5" with quickly diminishing amounts to the south and east.

If the coastal storm passes farther offshore, snowfall totals will be less, especially across the interior.
Conversely, if the storm tracks closer to southern New England, there would be less snow across most of the region, since the higher accumulations would shift to the northwest of MA.
