While many people across the country are preparing for Christmas by shopping for last-minute gifts and hanging ornaments on the tree, others are getting ready for the coldest weather event of the season. According to a report by a federal weather prediction agency, millions of United States residents are about to experience the chilliest Christmas in 40 years.

Although the weather is already fairly cold in many parts of the country, the Climate Prediction Center believes temperatures will continue to decline. “Very cold Arctic air masses will envelop much of the central and eastern half of the nation during the two week period, including the busy holiday travel season,” the Climate Prediction Center explained in a report.

Today, certain regions of the country will experience sub-zero temperatures. “Daytime lows on Tuesday dip as low as -20 to -30 in parts of Montana, with sub-zero lows bleeding more into the central High Plains,” the agency said. “Blustery winds throughout the region are responsible for bone-chilling wind chills, ranging as cold as -30 to even -60 degrees.”

Cold temperatures have caused the release of several wind chill warnings, advisories, and watches across the northern High Plains that are expected to be in effect for most of the week. By Christmas, it’s predicted that 80 percent of the country will experience below freezing temperatures, including regions of Texas and Florida.

The severe cold will make it possible for a winter storm to develop in the coming days, according to a weather report by CNN. It’s predicted that the storm will begin to form on Tuesday and impact the central and eastern U.S. People living in those regions are expected to see heavy snow, strong winds, rain, and colder temperatures. As for that white Christmas? It’s looking more and more plausible.
