- A storm system is expected to run along the northeast coast on Saturday.
- Rain, heavy winds and snow are expected, especially in New England.
- The nor’easter leaves quickly for Sunday.
Over the weekend, an east coast storm called nor’easter develops, bringing rain, wind and snow to parts of the northeast.
Like the storm earlier this week, dubbed Winter Storm Dane by The Weather Channel, this weekend the nor’easter is expected to evolve from combining the energy of two jet streams.

However, the weekend storm will lead much further east than at the beginning of the week.
This means that in some areas that were soaked by heavy rain earlier in the week, there may be more snow. There may be little rainfall in other areas hammered with snow earlier this week. However, in some areas, soaking is again experienced over the weekend, as before.
Winter storm hours have been issued by the National Meteorological Service for parts of New England from Massachusetts to Maine, where heavy snowfall can make travel conditions difficult, if not dangerous.
We also expect this low-pressure system to intensify on Saturday near the East Coast, probably fast enough to meet the bomb cyclone criterion later, Saturday.
Let’s start by determining the timing of the storm and then forecasting the snow, rain, and wind.
The low-pressure system begins to strengthen as it moves east.
During the day it will rain in the southeast and some thunderstorms and will cover parts of the mid-Atlantic. Isolated strong or severe thunderstorms can occur in the Florida Panhandle and the Eastern Carolinas.
On Friday night, the rain will spread from Florida to the south of New England. Along the northern rim, some of the precipitation associated with the cold front may fall as snow in some parts of the northeastern interior and in the appalaites.
The low pressure near the central Atlantic coast, off the coast of New England until evening, can be intensified and monitored.
Accurate tracking of lows is crucial in determining impacts. This includes the structure of the rain-snow line and the wind strength that can be generated by the system.
The chances of wind-driven rain will be in coastal and south-east New England as well as Long Island. However, rain later, on Saturday and Saturday nights, could turn into some snow in the south of New England.

The rain should end in the afternoon from New Jersey to the southwest.
It is most likely to extend north from the south of New England to parts of Vermont (New Hampshire, northern, central and western Maine).
Strong winds are likely in the North East, especially off the coast of New England as this system intensifies near the coast. There may be power outages.
By Sunday morning, most computer models would suggest that the low pressure would head to New Brunswick, Canada, or Nova Scotia.
Prolonged snow is expected in some parts of Maine, possibly in northern New Hampshire and northern Vermont.
Wind gusts can linger in New England and possibly other parts of the North East.
Snow, rain forecast
There is still some uncertainty about the exact trajectory achieved by nor’east near the northeast coast, which can affect the exact location of both the rain / snow line and the heaviest snow.
With a higher chance of snowfall over 6 inches, the greatest chance is in most of Maine, except the direct coastline as well as New Hampshire. In intensive, small-scale snow lanes, 1-2 inches of snow per hour is possible.

Most of the uncertainty about the amount of snowfall is in the south of New England, given the uncertain low footprint and marginal supply of cold air.
If precipitation has previously turned to snow and / or the low lane is slightly further east, more snow will fall in the south of New England, especially in Massachusetts. For now, we expect mostly rain in downtown Boston, but we can expect at least some snow accumulation in the western and northern suburbs.
Milder snow accumulations are expected in much of Vermont, upper New York, central and western New York, and the Appalachian Islands.
Rain is expected along Interstate 95 Corridor, from New York to Washington DC. Heavy rains are possible locally, but only isolated, minor heavy flooding is expected.

The National Meteorological Service issued windy afternoon and evening hours in southeastern Massachusetts, including Cape Cod, Martha’s Vineyard, and Nantucket, where gusts between 50 and 60 km / h could knock down trees and beat electricity.
Strong gusts above 50 mph on Saturday and Saturday night are also possible on Long Island, in the higher terrain of New England and along the coasts of Maine.
Power outages and tree damage are also possible due to the weight of heavy, wet snow and wind in the aforementioned parts of the North of England.
