The heavy snow invading the Northeast will graze the Interstate 95 corridor from Washington, D.C., to New York City to Boston, but eventually rain will win out over the snow.
Cold air will be stubborn to leave the Northeast's interior and northern New England, allowing significant snow to fall.
However, the same cannot be said for the I-95 corridor from Boston southward.
While enough cold air will be present for snow and sleet to accompany the complex storm as it reaches Washington, D.C., Baltimore, Philadelphia, New York City and Boston, milder air will arrive and lead to a change over to rain much quicker than places farther inland.
Still, a coating to inch of snow in Washington, D.C., and Baltimore early Monday and 1-3 inches in Boston early Tuesday could lead to slow and slick morning commutes.
New York City will also see a coating to an inch of snow around sunset Monday. Roads will become slushy with non-paved surfaces having the greatest chance of seeing an inch of snow. Only if a burst of snow accompanies the storm into New York City will roads turn white.

With the snow and sleet reaching Philadelphia during the late morning hours of Monday, wet roads are expected with a slushy coating generally confined to grassy and elevated surfaces.
It should be noted that a prolonged period of snow and sleet will create more slick conditions for travelers just north and west of all the I-95 cities from Washington, D.C., to Boston.
Even after the changeover to rain, it will not be smooth sailing for travelers. The rain will still create less-than-ideal conditions for motorists by reducing visibility, while low-hanging clouds and the rain threaten to delay airline travelers.
There is some concern that the rain could also lead to minor flooding issues across southeastern New England, where the ground is saturated from the runoff from recent storms. Minor coastal erosion will add to the worries of residents along the eastern Long Island and New England coasts Monday night through Tuesday.
Residents of Washington, D.C., should not be surprised that a snowstorm is bypassing the region with this winter's dismal snow total standing at only 1.7 inches at Reagan National Airport, the city's official weather reporting station.
If the winter season ended with this weekend, this winter and its 1.7 inches would rank third among Washington, D.C.'s least snowiest winters. The nation's capital typically records 15.2 inches of snow by St. Patrick's Day.
On the other hand, this winter's storm track has brought numerous rounds of snow to Boston. The winter's snow total currently stands at 55.9 inches, well above the 39.0 inches that typically falls by St. Patrick's Day and the 43.9 inches the city averages a winter.
