Northeast Forecast Sunday Night
Dion initially produced snow in Washington, California, Nevada and the Four Corners states during the first half of the weekend.
Now, Dion is spreading snow and ice from theMidwest to the Mid-South, Ohio Valley, Middle Atlantic and Northeast.
Here's a look at the forecast through the beginning of the new work week.
Megalopolis: D.C. to Boston
Washington, D.C.,Baltimore and Philadelphia can expect light snow accumulations Sunday followed by a transition to sleet and freezing rain, starting in D.C. in the afternoon and spreading to Baltimore and Philadelphia in the evening.
Hazardous travel conditions are possible, particularly on bridges and overpasses. This wintry mix will eventually changeover to rain in all three of these cities by midnight Sunday night (but earlier in D.C.).
A wintry mix will also develop in and around New York City Sunday night before changing to rain. The changeover will occur before the morning commute Monday except in parts of the Hudson Valley, where icy conditions may await early commuters.
For all four of these cities, it is expected to be the season's first measurable snow, meaning 0.1 inch or more of accumulation. The average date of the first measurable snow ranges from Dec. 14 in Baltimore to Dec. 18 in Philadelphia and Washington.

Boston and much of southern New England can expect some light snow late Sunday night before mixing with and changing to rain Monday. Only minor snow accumulations, in most cases less than an inch, are expected.
