From January 13 to 16, 2024, a wide-ranging winter storm, unofficially named Winter Storm Heather by The Weather Channel and news outlets, caused significant impacts across much of the continental United States, particularly in the Southern regions of the country. Originating as an extratropical cyclone over the northeastern Pacific Ocean on January 12 moved ashore the following day, bringing heavy snowfall and ice accumulations to areas closer to the coastline than usual. The winter storm then weakened over the Rocky Mountains, and leftover energy combined with an arctic front settling in near the Gulf Coast resulted in wintry precipitation in states that rarely receive it such as Texas, Louisiana, and Florida. The system then consolidated and intensified slightly as it began to move northwards towards the Mid-Atlantic states. It then moved just offshore and brought accumulating snowfall to most of the region as well as New England on January 16–17 before it moved into Canada soon after.

Widespread, significant and deadly impacts were observed from coast to coast in the U.S. due to the winter storm, as areas that normally did not receive frozen precipitation were affected adversely. In the Northwest, ice accumulations and high wind gusts knocked out power to many as the system moved ashore, in addition to later triggering avalanches in the mountainous regions of the states of Colorado and Utah the following day. Further east, bitter cold combined with the winter storm resulted in at least 30 deaths in the South, in addition to wintry weather resulting in closures and traffic delays across a large portion of the Southern United States. In the mid-Atlantic and New England, cities like New York City, Washington D.C. and Philadelphia saw their first accumulating snowfall over in nearly two years, ending a record 700-plus-day streak with no such accumulation.
