For days, temperatures have plunged across a large portion of the United States, accompanied by a storm system that’s brought sleet, snow, ice or a combination of all three. The weather has been a factor in several deaths, and has also caused treacherous travel conditions and numerous flight cancellations.

IOWA

The state’s first widespread snow of the year caused 20-car pileup on Interstate 80 in Des Moines, with no serious injuries reported and the road cleared by noon Sunday.

Most of Iowa is expected to see 2 to 4 inches of snow.

MARYLAND

State officials have asked motorists to stay at home while bands of expectedly heavy snow move across the state. A state Highway Administration spokeswoman said snow was heavier than forecasted and falling at a rate of an inch an hour in some parts of Maryland.

Baltimore officials cancelled the mayor’s annual Christmas parade on Sunday because of snow and dangerous road conditions.

MINNESOTA

Temperatures will stay well below freezing throughout Minnesota on Sunday, and another 2 to 5 inches of snow is in the forecast.

In northern Minnesota, the low was 35 below zero in Hibbing. Windy conditions could make it feel even colder in west-central and central Minnesota — with wind chills as much as 25 below to 30 below zero Sunday night into Monday morning.

NORTH CAROLINA

North Carolina is expected to see a range of wintry weather on Sunday. The north-central part of the state was under a winter storm warning through late Sunday afternoon and could see a mix of freezing rain and rain.

Elsewhere, Winston-Salem and Greensboro are under an ice storm warning, with accumulations of up to a quarter of an inch. A freezing rain advisory was issued for the Triangle area as well as the mountains and foothills.

PENNSYLVANIA
Up to 6 inches of snow were in the forecast for Philadelphia and southeastern Pennsylvania on Sunday. The snow was so heavy in Philadelphia that yard markers at Lincoln Financial Field were completely obscured during the Eagles’ game against the Detroit Lions.

Other parts of the state could see 1 to 3 inches before the precipitation changes over to sleet and freezing rain later Sunday and into Monday.

TEXAS

North Texas may start to thaw out a little on Sunday with some sunshine and temperatures that are slightly above freezing.

However, more than 400 departing flights were cancelled at Dallas-Fort Worth International Airport on Sunday. And road graders were called in to break up the thick ice on Interstate 35 north of Dallas, which has had many long traffic delays since the storm began Thursday night.

VIRGINIA

Freezing rain and sleet coated tree limbs and power lines throughout most of Virginia on Sunday morning, with the worst concentrated from Richmond to southwestern and western parts of the state.

Officials warned a major ice storm was possible in Virginia’s Appalachian region along the busy Interstate 81 corridor.

WASHINGTON, D.C.

Scattered delays affected airports near the nation’s capital, with runways needing treatment at Ronald Reagan Washington National Airport on Sunday afternoon. Baltimore-Washington International Thurgood Marshall Airport had plow crews standing by.

WISCONSIN

Snowy conditions contributed to numerous multi-car accidents in southeastern Wisconsin on Sunday, including a fatal rollover on Interstate 94 near Racine.

Up to 5 inches of snow is forecast to fall in southern and eastern Wisconsin by Monday.
