Another Potentially Travel-Complicating Snow Burst For Major Northeast Cities Tuesday

December 9th, 2013

* Another significant burst of snow is likely Tuesday for major urban centers from Washington D.C. and Baltimore to Philadelphia and New York.  Slightly lesser amounts across southern New England and metro Boston.

* Band of 3-6″ likely D.C. to Philadelphia with locally heavier 6″+ amounts possible; best chance of snow morning and midday hours. I expect 2-4″ in metro New York City. Expect significant air delays and cancellations from Dulles and Reagan National in D.C. to La Guardia, Newark and JFK in New York City Tuesday.

* Impacts to air/land travel likely – I envision extremely slow commutes. Little or no ice expected; the atmosphere should be cold enough for all-snow

Brewing Tuesday Travel Headaches. Major interstates are in fairly good shape this evening, but this will change, dramatically, within 12-15 hours as another surge of snow pushes across the Mid Atlantic Region into southern New England. Click here for real-time traffic reports, courtesy of Google.

Narrow Band Of Significant Snow. Our internal models show as much as 6-8″ for the western and southwestern suburbs of Washington D.C., a band of plowable snow from Charlottesville and D.C. to Baltimore, Wilmington, Philadelphia, much of New Jersey and metro New York City.

Advisories and Warnings. NOAA has issued Winter Storm Warnings for the Delaware Valley, which may have to be extended into Baltimore and Washington D.C. Winter Weather Advisories are in effect from the Virginia and Maryland into eastern Pennsylvania, New Jersey and New York City.

A Nagging Frontal Zone. Winter Weather Advisories extend from southeast Arkansas and northern Mississippi into eastern Kentucky and the Shenandoah Valley of Virginia, calling for a couple of inches of additional snow and ice.

Summary: A few weeks ago we warned of an active and wintry pattern for much of the East Coast, and that forecast seems to be verifying as a series of storms ripple along the leading edge of Arctic air. One such ripple of low pressure will squeeze out plowable amounts of snow from northern Virginia to New York City, with lesser amounts for Providence, Hartford and Boston. I’m especially concerned about Washington D.C. and suburbs, where mere flurries can wreak havoc. Tuesday will be a very forgettable travel day in the nation’s capital, with considerable impacts into Philadelphia and even metro New York City.
