2 adult and 4 children missing in Nevada snow

(CNN) -- Frigid weather gripping much of the United States led to a frenzied search in northwest Nevada, where rescue teams are scouring a mountainous area for two adults and four children who went to play in the snow and never returned.

James Glanton, 34, and Christina MacIntee, 25, are missing, along with Glanton's two children and MacIntee's niece and nephew. The children range from 3 to 10 years old, the Pershing County Sheriff's Office said.

The group set out Sunday for Seven Troughs mountain range and haven't been seen since.

Fears intensified as the temperature plummeted to below zero.

More snow and ice

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. 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.
