Heavy snowfall will spread over parts of the Northeast starting late Monday and into Tuesday, with some areas expected to get up to two inches of snow an hour, National Weather Service forecasters said.

This is not a long lasting storm; the snow will come down quickly and in some cases pile up to a foot or more.

Even Central Park, which hasn’t been coated in a half a foot of snow or more since Jan. 29, 2022, could see the return of sledding, snowballs and snowmen by Tuesday afternoon.

Here are key things to know about the storm.

• Snow is looking more likely for New York City, with the possibility of over six inches. It will start as rain in the city and will most likely transition to snow around the morning commute Tuesday.

• There remains some uncertainty around when, exactly, the precipitation will change from rain to snow in the New York metro area, which would affect eventual snow totals.

• The band of heaviest snow will fall from northern New Jersey to southern New England. Cities like Boston are likely to receive a foot of snow or more.

• Schools are announcing closures ahead of Tuesday’s storm. Boston Public Schools will be closed, according to the district’s website, and New York City Public Schools also announced that classes would be held remotely.

Snow is likely from the Mid-Atlantic through New England.

In its latest forecasts early Monday, the Weather Service said its forecasters were confident that Connecticut and the Lower Hudson Valley would see at least six inches of snow.

The heaviest snow will fall in northern Pennsylvania and southern New York before tracking into southern New England on Tuesday, the Weather Service said. As much as a foot of snow is expected in those areas, particularly in the Catskills of New York and the Berkshires in Massachusetts, forecasters said.
