A​n East Coast storm will bring high winds, heavy snow and rain to parts of the Northeast and New England.

T​here are key forecast details, such as how much snow will fall and where, that are still yet to be determined. This is typical for East Coast storms several days away.

T​his system has been named by The Weather Channel.

S​age's Midwestern Story

B​lizzard conditions caused whiteout conditions across nearly all of North Dakota, Saturday afternoon. Numerous roadways across the state, including , were closed. Blizzard conditions were reported in Leeds and New Rockford, North Dakota, with wind gusts as high as 45 mph.

S​age is bringing gusty winds and snowfall to parts of the Great Lakes into the mid-Atlantic while bringing some rain and thunderstorms to portions of the Southeast.

C​urrent Alerts

W​inter storm warnings and winter weather advisories are in effect in parts of the Upper Midwest, where driving could be dangerous. White out conditions are possible in these areas.

W​inter storm watches will be in effect early week in portions of New England and eastern New York. Travel could be very difficult to impossible in that area beginning Monday.

Where the low tracks is key. After moving through the Midwest this weekend, we expect low pressure to form and strengthen off the East Coast beginning Monday.

This storm may become a , a type of storm that typically crawls up the East Coast with winds blowing out of the northeast ahead of it.

While not as plentiful as you might expect in the heart of winter, there appears to be just enough cold air with this system in at least parts of the interior Northeast. But it not may not be very expansive relative to a storm of this type in January, and could be scoured out by the storm in some areas.

T​iming

Monday: Snow, possibly heavy, will fall in the interior Northeast with rain closer to the Interstate 95 corridor from southeastern New England to the mid-Atlantic. Winds will likely increase along much of the Northeast Seaboard.

Tuesday: Snow, possibly heavy, will fall in most of New England and New York. That could mix with or change to rain in parts of southern and coastal New England. Strong winds are expected, particularly in coastal New England, but also in much of the Northeast.

Wednesday: Snow showers and strong winds could linger in New England at least early in the day.

P​otential Impacts

S​now

F​or now, the most probable area for heavy snow is in parts of western and northern New England into upstate and central New York state and northeastern Pennsylvania. Snowfall amounts may drop dramatically as you near the immediate Interstate 95 corridor from downtown Boston to New York City, where at least some rain is expected.

That said, any shift in the track of the low could change this forecast in the coming days.

Snow, Rain Outlook

(While it is too far out in time to specify exact forecast snowfall totals, areas in the purple and pink contours have the highest chance at heavy snowfall.)

W​ind, Coastal Flooding

A​s we mentioned earlier, winds are expected to increase along the Eastern Seaboard starting late Monday. By Tuesday, wind gusts over 50 mph are most likely along coastal and southeast New England. In these areas, power outages and at least some tree damage is possible.

Tuesday into early Wednesday, much of the rest of the Northeast could see wind gusts of at least 40 mph, at times. Those gusts, combined with the weight of heavy, wet snow, could lead to some tree damage and power outages in areas of significant snow accumulation in the interior Northeast.

T​hese onshore winds could lead to some coastal flooding at high tide in parts of coastal New England Monday night into Tuesday.

Check back frequently for updates in the coming days, including more details on how much snow, rain and wind are expected as this forecast comes into focus.
