Winter Storm Dion 2013 Update: More Snow Hits Northeast

Heavy, fast-moving snow has hit the Northeast once again, forcing schools to close and creating messy morning commutes.

Winter Storm Dion, the fourth winter storm of the 2013-14 season, brings more snow and ice to the Great Lakes and Northeast on Tuesday.

Dion produced snow in Washington, California, Nevada and the Four Corners states during the first half of the weekend before bringing light ice to parts of the south-central U.S. It also brought snow to the Mid-Atlantic--Philadelphia in particular--as well as to the Midwest.

Areas hit by snow and ice on Monday are expecting additional snow and/or ice through Tuesday morning, Weather.com reports.

Snow fell overnight in the Ohio Valley, including Louisville, Ky. and parts of West Virginia. Amounts were not heavy, but there was enough snowfall to cause problems for the morning commute.

Driving conditions will worsen on Tuesday morning for parts of the Mid-Atlantic, including the I-95 corridor from northern Virginia to New Jersey. Snowfall rates could reach 1 inch per hour, which could lead to snow-covered roads for hours.

Philadelphia, Washington D.C. and Baltimore will see 2 to 5 inches of snow, although some areas in that region could see accumulations of over 6 inches. A winter storm warning is in place for those areas.

The Philadelphia School District has closed, as have other schools in the surrounding region.

Some light snow could extend into New York City and southern New England. Although those areas will see light accumulations, it is likely to slow traffic. It is expected to be the season's first 1-inch snowfall for New York City.

Most of the snow will be out at sea by the Tuesday evening commute. However, some light snow may linger in Long Island and southern New England, which could affect commuting home.

Dion's after-effects will send cold air blowing across the Great Lakes, which could create lake-effect snow in those areas Tuesday through Thursday. The snow could be heavy east of Lake Ontario, north of Syracuse, where snow could be well over a foot.
