Snow to create slick travel over parts of northeastern US into Tuesday

As colder air sweeps into the northeastern United States, snow will create slippery travel in some communities into Tuesday.

After experiencing an early taste of spring this weekend, residents will once again be reaching for snow shovels across parts of the Northeast in the final days of January.

Two main areas of snow will affect the Northeast on Tuesday.

Enough snow to cause slippery travel and disruptions to daily routines is expected. That is especially true when untreated roads and sidewalks are coated at night and in the early morning hours and/or when snow falls heavily even during the daylight hours.

Several inches of snow fell around Lake Erie with up to a couple of inches coating parts of the central Appalachians.

A coating to an inch of snow can lead to slow and slippery travel in the vicinity of Baltimore and Philadelphia, before diminishing by the early afternoon.

Part of the area from eastern Pennsylvania to Delmarva and southern New Jersey can expect a burst of moderate snow during the middle part of the day before the storm departs.

Airline passengers should expect additional delays due to aircraft deicing activity.

Moderate snow began to fall on southeastern New England and central and eastern Long Island, New York, during late Monday night and was in progress on Tuesday.

Snow from the coastal storm will continue to impact New York City and southeastern New England into the midday hours. Enough snow to shovel and plow has already fallen east of New York City.

"A return to much colder conditions is certain across the Northeast Tuesday into Wednesday," Pydynowski said.

In many communities from the Midwest to the Appalachians, temperatures may not climb above freezing on Tuesday. Temperatures may crack the freezing mark in New York City, Philadelphia and Washington, D.C., this day, but only by a few degrees.

Plunging temperatures on Tuesday night can cause any lingering wet or slushy areas in the mid-Atlantic to turn icy on untreated surfaces.

Temperatures may rise ahead of the next storm due to arrive Thursday night and continue into Groundhog Day. However, fresh cold air is likely to catch up with the storm fast enough to produce a swath of snow across the Northeast.
