Northeast Braces for Another Round of Snow and Freezing Temperatures

The pre-winter wintry weather isn't over yet. Temperatures in storm-stricken parts of the country are expected to stay about 10 to 20 degrees below normal for the rest of the week, the National Weather Service said.

Federal offices in Washington are closed Tuesday as more sleet, snow and freezing rain are expected,CNN's Chris Lawrence reports.

And a swath of 2 to 6 inches of snow is expected to fall Tuesday from Virginia to the New England coast, forecasters said.

Philadelphia can expect to get 3 to 5 inches of snow on Tuesday; New York, a little less than that.

The storm will finally leave the East Coast late Tuesday, but the mercury won't rise above freezing until at least Friday, the National Weather Service said.

Elsewhere across the country, Portland, Oregon, and Chicago will see snow and freezing rain this week.

Even St. Louis has been colder than Anchorage, Alaska.

"It's very unusual," CNN meteorologist Dave Hennen said. "This literally spreads across the entire U.S."
