Story at a glance
- The Northeastern and Mid-Atlantic states should expect significant snowfall this week.
- The storm bringing the snowfall will move from the West Coast to the East, buoyed by moist and gusty winds.
After a record-breaking hurricane season that clobbered the Atlantic and Gulf Coasts, other parts of the eastern U.S. are gearing up for more intense weather as forecasters predict a massive snowstorm will hit the New York City metro area this week.
CBS notes that cities along the U.S.’s populous East Coast, including Washington D.C., Boston and Philadelphia, are all likely to see nor’easter snow over the next few days.
This comes after mild winters with low snowfall.
Meteorologists point out that the nor’easter set to hit the East Coast stems from a storm much further west. It is set to hit Washington state and Oregon with heavy snowfall before moving east, past the Rocky Mountains and Midwest states, where it will meet moisture from the Gulf Coast, increasing the amount of snow.

Even more damp air from the Atlantic Ocean will bring heavy snowfall to northern Virginia, Maryland and Pennsylvania by Wednesday afternoon.
The aforementioned larger urban areas will see several inches of snow soon after.
Reporters point out that what makes this storm significant is a strong, cold high-pressure system coming down from Canada that is expected to keep cold weather in place in the Northeastern U.S.
“Assuming all of those ingredients come together as shown below, we could be looking at one of the more impactful Northeast winter storms in the last couple of years,” Weather.com writes.
