A massive winter storm is sweeping across the United States, affecting over 60 million people in 30 states. The storm is linked to a polar vortex, a cold air system usually huddled over the North Pole. This time, it's making its way south, bringing snow, ice, and severe cold to many regions.

Some states like Kansas, Arkansas, Kentucky, and Virginia have already declared emergencies. Even Southern states like Mississippi and Florida are bracing for dangerous conditions. The storm is expected to bring the heaviest snow in over a decade to some areas. Major airports have faced delays and closures, including Kansas City International Airport, which briefly shut down on Saturday.

Interstate 70 in Kansas was also closed due to expected heavy snowfall and blizzard conditions. The National Weather Service has warned of disrupted daily life, including difficult travel and widespread closures. Cities like Cincinnati, Chicago, and St. Louis have prepared by treating roads and setting up warming centers.

As the storm moves east, it could bring severe weather to the lower Mississippi Valley. Some places might face tornadoes, damaging winds, or hail. The storm might also bring record-low temperatures to many regions. Places like Washington D. C. , Baltimore, and Philadelphia are getting ready for snowy and icy conditions. Southern states may also face severe thunderstorms.

This storm has caused thousands of flight delays. Airlines like American, Delta, Southwest, and United have waived change fees due to expected disruptions. After the storm, temperatures are expected to drop by 10 to 25 degrees below average for the next week. The northern Plains could see temperatures as low as minus 20, with wind chills around minus 40.
