The January 13–16, 2024 North American winter storm brought wide-ranging and 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, the system, unofficially named Winter Storm Heather by The Weather Channel, 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.
