A powerful storm system is barreling across the U.S., bringing severe thunderstorms, heavy snow, and damaging winds that could disrupt travel, knock out power, and trigger flash flooding. Here’s what you need to know about the timing, risks, and how to stay safe.
The Storm’s Two-Phase Assault
This isn’t a single weather event—it’s a prolonged, two-phase crisis that will evolve over 72 hours, affecting nearly every region east of the Rockies. The system has already proven its destructive potential, with Thursday’s storms generating wind gusts over 80 mph and confirmed tornadoes in Oklahoma. Now, the threat is shifting eastward and intensifying.
Phase 1: Friday’s Severe Weather and Snow
Severe Thunderstorms: The most immediate danger on Friday will be in the South, where a Level 2 out of 5 risk for severe weather has been issued for cities like Birmingham, Alabama; Jackson, Mississippi; and Baton Rouge, Louisiana. Damaging winds, large hail, and isolated tornadoes are possible, particularly in the Lower Mississippi Valley and Tennessee Valley. The storms could persist into Friday night, keeping the threat alive well after dark.
Snowfall: Meanwhile, snow will continue to blanket parts of the central and southern Rockies, extending into the High Plains, including southern Colorado, northern New Mexico, western Kansas, and the Panhandles of Oklahoma and Texas. While accumulations are expected to remain light to moderate, the snow will be accompanied by strong winds, reducing visibility and creating hazardous travel conditions.
Phase 2: Saturday’s Expanding Threats
By Saturday, the storm’s impacts will broaden dramatically:
- Snow: The focus shifts to the western Great Lakes and upper Midwest, where accumulating snow could disrupt travel in cities like Minneapolis and Chicago.
- Heavy Rain and Flooding: Soaking rains will spread eastward, reaching as far north as New England. The Deep South, still reeling from Friday’s storms, faces the highest risk of flash flooding, with flood watches already in effect from Middle Tennessee to southern Louisiana.
- Damaging Winds: The most widespread hazard will be strong wind gusts exceeding 40 mph across the Midwest and East. These winds could down tree limbs, knock out power, and make driving treacherous, especially in areas with wet or snow-covered roads.
- Severe Storms: While the primary severe weather threat will have shifted east, isolated strong to severe thunderstorms could still develop as far north as the mid-Atlantic, including parts of the Carolinas and southern Virginia.
Why This Storm Is Different
This isn’t just another winter storm—it’s a complex, multi-hazard event with several unusual characteristics:
- Unseasonably Warm Air: Despite being early January, the lack of bitterly cold air means this system won’t be a major snowmaker east of the Rockies. Instead, the clash between mild, moist air from the South and the storm’s cold front will fuel severe thunderstorms and heavy rain.
- Prolonged Wind Threat: Unlike typical storms where winds subside quickly, this system will maintain strong gusts through Sunday, prolonging the risk of power outages and travel disruptions.
- Rapidly Shifting Threats: The storm’s two-phase evolution means communities will face different hazards in quick succession—first severe storms, then flooding, then wind, and finally snow in some areas.
What’s Already Happened
The storm system has already left its mark. On Thursday, severe thunderstorms erupted in the Southern Plains, producing:
- Wind gusts up to 88 mph in Wynona, Oklahoma, causing roof damage and destroying outbuildings.
- An 81 mph gust near Independence, Kansas, downing power lines and poles.
- A confirmed tornado near Purcell, Oklahoma, which overturned a semi-truck on Interstate 35 and damaged structures.
- Penny-sized hail and 60 mph winds in the Oklahoma City metro area.
These early impacts serve as a warning of the storm’s potential as it moves eastward.
How to Stay Safe
With multiple hazards unfolding over several days, preparation is key. Here’s what you can do:
- Severe Weather: If you’re in the South, have a way to receive warnings (e.g., a weather radio or smartphone alerts) and know your safe place in case of a tornado. Avoid driving during storms, as high winds can make roads dangerous.
- Flooding: Never attempt to drive through flooded roadways. Just 6 inches of moving water can knock a person off their feet, and 12 inches can sweep away a car.
- Wind and Power Outages: Secure loose outdoor items that could become projectiles. Charge devices and have backup power sources ready. If you rely on electric medical equipment, have a plan in place.
- Snow and Travel: If you must travel in snowy areas, pack an emergency kit with blankets, food, water, and a flashlight. Check road conditions before heading out.
The Bigger Picture: Climate and Extreme Weather
This storm is part of a broader trend of increasingly volatile weather patterns. While no single event can be directly attributed to climate change, the rising frequency of high-impact, multi-hazard storms aligns with scientific predictions. Warmer air holds more moisture, fueling heavier rainfall and more intense storms. At the same time, shifting jet streams can lead to prolonged periods of severe weather.
For the U.S., this means more events like this one—where severe thunderstorms, flooding, snow, and damaging winds occur in rapid succession, straining emergency response systems and leaving communities little time to recover between hazards.
As this storm unfolds, stay informed with the latest updates and prioritize safety. The next 72 hours will test the resilience of millions, but with the right preparation, the risks can be minimized.
