Dangerous Cold Plunges into United States

While we have been focused on the snow that blanketed much of Colorado this morning and continues to bring snow showers to the region through Sunday, there is another story to share regarding the bitter cold that will put much of the CONUS in an icebox for the next several days. This system is forecast to bring the coldest temperatures in years to portions of the midwest.

While Denver won't feel the brunt of it the system, it will get cold. In fact, lows both tonight and Sunday night are expected to drop into the single digits, with below zero readings possible for many locations across the region. Highs Sunday will be colder than today, with temperatures hovering in the teens along the Front Range.

Meanwhile, portions of 13 states across the midwest are now under Wind Chill Warnings posted by the National Weather Service. States like North Dakota and Minnesota are gearing up for wind chills from 45 to 75 degrees below zero over the next 48 hours. Wind chills like this can cause frostbite to exposed skin within minutes.

Temperatures will be cold almost nationwide, with overnight lows dipping below freezing for most of the United States by Tuesday. Check out this ECMWF probability map from WeatherBell showing chance for temperatures at or below 32 Tuesday (right) and below zero Monday (left). Keep in mind these are for actual temperatures, not taking into consideration the wind chill.

These are some incredible temperatures, the likes of which many locations have not seen in decades. Temperatures for Sunday's matchup between Green Bay and San Francisco Sunday will likely be one of the coldest NFL games on record. Temperatures at kickoff are expected to be about 2 degrees below zero with wind chills dipping below -20. Temperatures are expected to fall throughout the game.

If you are traveling to any of these locations over the next few days, please be aware of the weather and take necessary precautions to be out in these temperatures. Or better yet, stay home.
