In the middle of the week it is becoming more likely that there will be a major snowstorm on the east coast The Weather Channel – Articles about the weather channel


  • A winter storm on the east coast by mid-week is becoming more likely.
  • Colder air can lead to heavy snow near Interstate Corridor 95, or just north and west of it.
  • The storm will be at its peak from Wednesday to Thursday, but much uncertainty remains.

From a larger Norwegian eastern Wednesday, it is increasingly likely to cause heavy snowfall, strong winds and coastal flooding in parts of the central and northeastern Atlantic. Significant winter storm impacts are possible not only in the northeast, but also on parts of the Interstate 95 from Boston to New York, Philadelphia, and Washington DC

The top-level energy that caused the East Coast storm is now shifting to the western U.S., where it will spread snow to the Rockies until Monday.

Once this energy reaches the eastern states on Wednesday, it will promote and strengthen the low-pressure area near or near the east coast. At the same time, strong high pressure in eastern Canada is expected to bring fresh, cold air to the Northeast.

If all the ingredients come together as follows, we can see one of the worst winter storms in the Northeast in recent years.

As usual a few days before the storm, this forecast still contains some uncertainties. This includes the exact trajectory of the low surface and how strong and persistent the cold air will be along its path.

Here’s what we know about timing and expected monthly aggregation. Considering the uncertainty mentioned above, expect changes in the forecast over the next few days.

Forecast timing

Before this mid-week storm occurs, there will be a minor weather system that will bring light snow and rain to parts of the Northeast on Monday. Click here for more details about the system.

Tuesday-Tuesday night

The top-level energy that triggered the development of the East Coast storm will move from the plain to the Southern and Ohio Valley on Tuesday and Tuesday evenings.

Mostly light snow is expected at this time from the Central and Southern Plains to the Ozarks and Ohio Valley.

Some mixed rainfall may occur in the eastern central and southern Appalachian Islands as early as Tuesday night when the cold air will be cupped to the south. This can lead to frosty rain, snowfall, or snowfall in western North Carolina.

Wednesday-Wednesday evening

Wednesday and Wednesday evening is the period when most areas will hit peak due to this east coast storm.

Significant heavy snowfall and strong winds are likely at this time in the central Appalachian Islands, the mid-Atlantic, and the Northeast. This may include parts of the Interstate 95 corridor from Boston to New York, Philadelphia, Baltimore and Washington DC

A mixture of tin rain and frosty rain can occur up to western Piedmont in north-north Carolina and southern Virginia.

In larger east coast cities, the possibility of more snow depends largely on the exact trace of the storm, which determines whether certain areas have turned to winter mix or precipitation, especially near New York City or from south to south.

Near or north of New York City and south of New England, places are likely to stay cold enough to see all the snow. However, the storm’s more distant sea track could reduce the chance of snowfall in the south of New England.

In addition to heavy snowfall and strong winds, coastal flooding can also occur from the mid-Atlantic to New England.

Wednesday evening outlook

Thursday

The storm begins to linger from the Northeast on Thursday morning.

At least part of Thursday in the northeast may miss snow and wind. In most places, weather conditions are expected to improve by the second half of Thursday.

How much snow?

An extensive area of ​​the central Appalachian Islands, the mid-Atlantic, and the Northeast should see at least accumulating snowfall due to this storm.

The totality of storms of 6 inches or more may spread to some parts of these regions and some areas will exceed the foot. However, it is too early to determine exactly where these heavier amounts may fall compared to the Interstate 95 Corridor.

For now, don’t focus on the exact snowfall locations or total values, but take the figure below to see that higher-end snowfall may occur on the northeast coast, possibly somewhere in the northeast megapolis.

Check back often for forecast updates, as key details will be highlighted over the next day or two.

Chance of snow

(While it is too far to pinpoint the total amount of snowfall forecast, areas with purple and pink outlines have the highest chance of heavy snowfall.)
