(CNN) — As a major storm system moves across the central US and Great Lakes regions, Boston and New York City are on track for their biggest snow events of the season after an unusually warm winter, according to CNN meteorologists.

Both cities are under a winter weather advisory as snow and ice are expected to move in later Monday, according to the National Weather Service.

It could easily be New York’s biggest snow event of a nearly snowless season. The weather service is forecasting 4 to 6 inches of snow and ice in New York City from Monday evening through midday Tuesday, along with winds gusting to 35 mph.

“Better late than never! New York City has only received 0.4″ of snow so far this winter (since Dec 1), about 2 feet under their average,” CNN meteorologist Brandon Miller said. “But that looks to change on THE LAST DAY of meteorological winter (which runs Dec 1 – Feb 28).”

Boston is forecast to get up to four inches of snow through Tuesday night, which would be its biggest snowfall of the season as well. The city’s largest snowfall so far was just 2.3 inches on January 23. Boston has seen less than a third of its normal snowfall this winter, about 10 inches total compared to a normal of 3 feet, Miller said.

The unusually snowless winter prompted Mayor Gary Christenson of Malden, Massachusetts, just north of Boston, to declare winter over on February 8, when he tweeted the city was lifting all winter parking restrictions for its roughly 65,000 residents.

“This year, winter parking rules began on February 1st but were quickly removed due to a warmer-than-average weather pattern in February,” the city announced on its website.

Winter weather expected across the Northeast through midweek

Winter weather alerts, which include both winter storm warnings and winter weather advisories, are in effect for parts of central Pennsylvania through central Maine through Tuesday, according to the weather service. The highest snow amounts are expected across interior portions of New York, Connecticut and into the Berkshire mountains in Massachusetts, where up to a foot of fresh powder is possible.

Mixed precipitation is expected in parts of central Pennsylvania, including 1-2 inches of snow and sleet in the valleys and 2-4 inches on higher ground; ice accumulation is also expected. Parts of central and upstate New York could see 2-5 inches of snow and up to a quarter inch of ice.

“Plan on slippery road conditions. The hazardous conditions could impact the morning or evening commute,” the weather service warned.

The threat of snow and ice moves into New Hampshire and Maine starting Tuesday morning through Wednesday morning.

Drought isn’t a concern

Despite the minimal snow this season, the Northeast is not under threat of drought, and if anything, the situation is improving.

“Essentially, the snow drought is not equaling an actual drought for the Northeast,” according to Miller, who added the region is experiencing the normal number of storms and amounts of precipitation, it’s just falling as rain, rather than snow, due to the warm temperatures.

Weather Prediction Center Branch Chief Greg Carbin told CNN in January “the East is certainly in a snow drought with some locations that normally have snow, down by as much as one to more than three feet.”

The period between snow events is also likely to increase as the climate warms, and it may be especially true for coastal Northeastern cities. As the Northeast temperatures warm, the rain-snow line shifts farther north, leading to more rainy winter days along the coast and less snow, according to the US National Climate Assessment.

And it’s not just the Northeast. Meteorological winter, which spans December, January, and February, is also the fastest-warming season for 75% of 238 US locations, according to Climate Central’s data analysis.

While much of the Northeast, with the exception of western New York, has had nearly no snow this winter, the western US is a different story as feet of snow blanketed parts of southern California over the weekend, with blizzard warnings and winter storm warnings in effect again Monday.

Boston and New York City are gearing up for their biggest snow of the season — and it’s not even that much
