Arctic air grips Central, Mid-South regions

An arctic blast is set to bring some of the coldest temperatures of the winter across various regions of the United States, including Idaho, Central Texas, and the Mid-South. In Idaho, temperatures are expected to drop significantly, with Martin Luther King Jr. Day marking the coldest day, as a back-door cold front settles in, extending a dry spell. Central Texas is bracing for temperatures to plunge into the low 30s with wind chills in the teens, while the Mid-South will experience highs in the 20s and 30s, with wind chills feeling even colder. A cold weather advisory has been issued in multiple areas, urging residents to take precautions against frostbite and hypothermia due to dangerous wind chill factors. Additionally, some regions could see light snowfall or a mix of precipitation early next week. Overall, the frigid weather is expected to persist, with temperatures below freezing for several days.
