BOSTON (CBS) – Get ready for some new snow this week.

Light snow will fall on the Massachusetts coast Monday, but there's a storm coming Wednesday.

A localized threat for ocean-enhanced snow showers will bring light accumulation and difficult travel along the coast during both commutes Monday.  A winter weather advisory is up for most of Plymouth County and eastern Norfolk County until 10 p.m. Monday.

TIMING

Localized bands of snow will develop Monday morning anywhere from Cape Ann to Boston to the South Shore.

Snow continues across Quincy, and will start to pick up across Cape Cod for the lunch hour.

During the afternoon the few light bands may taper off, then a heavier band looks to bring snow across the south shore and as far inland as Rhode Island for the evening.

A north, northeast wind, moving across the warmer ocean water gives us this snow potential. The evening commute will be tough especially along Route 3 where the snow band is.

As you drive from Boston to the South Shore, you could have a clear sky, then run into that band with near zero visibility and quick accumulation.

These are the events that cause car accidents.

TOTALS

Along the immediate coast 1-3 inches. Dusting to 1 inch farther inland.

There could be a very localized area that may get 3+ inches. Accumulation will be gradual from Monday morning to Monday night.

IMPACTS

Highest impact will be felt across the South Shore and southeastern Massachusetts.

Low visibility, light accumulation and a tough morning and evening commute especially along Route 3.

OUR NEXT STORM:

The next storm coming in will have a more widespread impact to the region. Winter storm watches have now been posted north and west of Boston and will be upgraded to warnings as we get closer to the onset of this event.

Snow will develop Tuesday overnight, expanding through the pre-dawn hours of Wednesday. Both the morning and evening commutes will be impacted on Wednesday; expect snow covered roads, slippery travel, reduced visibility and difficult travel.

The heaviest snow will be from mid-morning until the early evening hours. The biggest uncertainty at this point is how far north the rain/snow line will come on Wednesday afternoon.

With temperatures in the 30's for many Wednesday, the consistency of the snow won't be fluffy – think more along the lines of a more "snowball making" type.

Our early thinking in terms of accumulation is for a widespread 3-to-6 inches, although less in southeast Mass. and potentially more than 6 inches north and west of Boston.

We will be tweaking this map over the next 24 hours, so stay tuned to WBZ-TV and CBS Boston.com for updates.

Thankfully, there won't be any coastal or wind concerns with this disturbance.
