SIDNEY - While snow across the Sidney area tapered off Sunday morning, the cold temperatures did not go anywhere as a massive arctic air mass grips the central United States.

The National Weather Service says over 150 million Americans are currently under winter storm warnings, ice storm warnings, winter storm watches, winter weather advisories, wind chill warnings or wind chill advisories.

"Many areas east of the Rockies and west of the Appalachians to witness dangerous and record-breaking cold into the first half of the upcoming week," according to the Weather Service. "Hundreds of daily low maximum and minimum temperatures will be broken with some February and even all-time low temperature records in jeopardy."

Wind chill warnings and advisories are in effect through 11 a.m. Monday in the Nebraska Panhandle, northeast Colorado and southeast Wyoming. The NWS says the "feels like" temperature could be as low as 25 to 40 degrees below zero, especially Sunday and Monday mornings. 

Wind chill values Sunday morning ranged from 25 to 35 degrees below zero.

"Bundle up, limit time outdoors and carry a winter survival kit in your vehicle," the Weather Service said in a statement. "Remember that frost bite and hypothermia can set in rapidly when wind chills fall below zero. These cold temperatures will be especially hazardous for newborn livestock."

Wind Chill Advisories extend as far south as the Southern Plains and as far east as the Ohio Valley, according to the NWS. Single digit highs stretch as far south as the Texas Panhandle.
