Northern Massachusetts is expected to bring heavy snow with blizzard-like conditions on Tuesday

A potential blizzard could bring arable snow to Massachusetts on Tuesday. Here’s the latest forecast for the Boston area from the WBZ NEXT weather team.

BOSTON — Chances are rising that a high-impact nor’easter will hit southern New England on Tuesday, with blizzard-like conditions possible in locations.

Since this storm is still several days away, nothing is certain yet. However, confidence has increased that we will see some very real impacts here.

Snow storm tracking

Looking at the different storm track scenarios, the far north track (closest to southern New England) seems the least likely at the moment…say about 10%.

That meant a milder and wetter storm (rain in parts of the area).

There is still a good chance that the storm will move too far south to be considered a “trigger” here. I would say there is about a 30% chance that we will be “fringed” or caught by the northern edge of the storm. This will likely bring some snow to our area, especially south of Boston, but it will spare us the full impact.

Finally and unfortunately, the most likely scenario as of Friday appears to be a more classic New England storm track.

When will the snow storm start in Massachusetts?

Much of our area is more likely to see snow on Tuesday, good winds and coastal flooding.

The schedule will likely need to be adjusted, but for now, plan for snow starting early Tuesday morning and continuing through most of the day. Tuesday may be one of those scenarios where schools have to make a “game time” decision when it comes to snow — there will only be light layers by early Tuesday morning before the storm actually intensifies.

The latest snowfall forecast calls for 6-12 inches widespread across much of the interior, including Worcester County and Middlesex in the Merrimack Valley. Smaller amounts of snow are expected along the coast, where marginally warmer waters will lower totals slightly, especially through the south shore.

Boston has a current streak of 715 days since the last 4 inches or higher of snowfall, the longest such streak on record. It is very likely that we will break this line on Tuesday evening.

Fears of coastal flooding with the storm

Perhaps worryingly, the storm may strike during one of the highest tidal cycles of the year. The absolute highest astronomical tides occur from Saturday to Monday. By Tuesday, these levels have come off their peak but are still very high. So, a Nor’easter-type storm wouldn’t be good news for people living along the Nor’easter River East facing coast.

There were a few locations that saw some minor coastal spots this morning during high tide. Tides are expected to be at or above flood level over the next few days.

The biggest concern is the high tide early Tuesday afternoon.

If this coincides with the peak of the storm, moderate to major coastal flooding may occur in some areas.

Regardless of whether Tuesday’s storm is successful or not, we are about to enter a colder period and possibly snowfall.

The next few weeks (at least) are likely to be cold and windy at times. Sorry Phil But your forecast for the beginning of spring does not look good at the moment!
