BOSTON (CBS) – Snow, coastal issues, and gusty winds will be an issue for many in southern New England on Tuesday.

TIMING

Roads are slick and snow covered for the morning commute.

Expect a more steady snowfall across southeastern Mass through central Mass, up to Cape Ann and the New Hampshire coast.

Some forecast models have the snow out of most locations after 10 a.m. Some later runs keep the snow around longer, say through noon.

SNOW TOTALS

We expect 2-to-5 inches of snow accumulation across southeastern Massachusetts, Cape Cod, Martha’s Vineyard, and Nantucket.

Depending on where the heaviest snow bands set up, we could see isolated spots of 6 inches.

A coating to 2 inches of snow in Boston, to southeastern New Hampshire, Worcester County, Providence, to eastern Connecticut.

A winter weather advisory is in effect until 10 a.m. Tuesday for the South Shore, coastline around Buzzards Bay, Cape Cod, Nantucket and Martha’s Vineyard.

Snowfall rates of 1 inch per hour will be possible Tuesday morning in the advisory areas.

WIND

As the center of low pressure passes well offshore, we will get scraped with the outer bands of wind.  Speeds of 15-25 mph and gusts up to 30-35 mph from the northeast.

The wind stays strong through Tuesday morning. As we approach high tide (between 9-10 a.m.) the seas will be churned up offshore and the north, northeast direction may bring splashover or minor pockets of flooding.

Peak gusts around 35 mph. Again, not a major wind issue on the coast, but it does contribute to the flood impacts. Inland we see peak gusts of 20-25 mph. Colder air starts to funnel in from the north.  Temps will be in the 20s further northwest.

A north, northwest wind will push 30 mph across southeastern Mass Tuesday evening.

This wind direction change will bring colder temperatures, falling into the teens Tuesday night into Wednesday morning.

COASTAL FLOODING

We have higher astronomical high tides this week thanks to a super moon on Wednesday (also a “blue moon”).

This means we have to watch for the Tuesday morning high tide for the coastal flood potential.  With a northeast wind pushing the waves onshore, we will see splash over and perhaps some minor coastal flooding.

Nothing like what we had during the last major flood event on January 4 though.
