South Dakota is facing one of the coldest and most dangerous weather events of the season as a powerful polar vortex grips the state. The National Weather Service has issued extreme cold warnings and winter storm alerts, warning residents to prepare for life-threatening temperatures and heavy snowfall. Temperatures have already begun to drop sharply. In Sioux Falls, the current reading sits at -10°F (-23°C), but forecasters say it’s about to get much worse. By tonight, lows will plummet to -19°F (-28°C), and with powerful winds sweeping through the state, wind chills could reach a staggering -40°F (-40°C). At these levels, frostbite can occur in just five minutes on exposed skin, and hypothermia is a major risk for anyone caught outside without proper winter clothing.
Major Snowstorm to Dump Several Inches Across the State
Adding to the brutal cold, a major snowstorm will sweep across South Dakota over the next few days, dumping 6 to 12 inches (15 to 30 cm) of snow in some areas. Rapid City is already seeing light snowfall, with forecasters predicting that it will intensify by Tuesday. Combined with gusty winds up to 40 mph, visibility will drop to near zero in some locations, creating blizzard-like conditions and extremely hazardous roads. Authorities are strongly advising against travel, warning that roads will become ice-covered and nearly impassable due to blowing snow and drifting. If you must drive, officials recommend carrying an emergency winter survival kit in your car, including blankets, food, and water, in case you get stranded.
How This Storm Will Disrupt Daily Life
The combination of extreme cold and significant snowfall is expected to cause major disruptions across the state.
- Power Outages Possible: High winds, ice buildup, and increased demand for heating could lead to power failures in some areas. Residents should charge devices, stock up on batteries, and have alternative heat sources ready.
- School and Business Closures: Many districts may cancel classes, and businesses could close due to dangerous commuting conditions. Check local alerts before heading out.
- Grocery Stores Could Be Emptied: Panic buying may lead to shortages of essential supplies, so it’s best to stock up now before roads become unsafe.
How to Stay Safe in This Extreme Cold and Snow
- Limit Outdoor Exposure – Wind chills of -40°F can cause frostbite in minutes. If you must go outside, wear multiple layers and cover all exposed skin.
- Prepare for Power Outages – Keep flashlights, extra batteries, food, and water in case of extended outages.
- Avoid Travel – If you must drive, carry emergency supplies in your vehicle and let someone know your route.
- Check on Vulnerable Neighbors – The elderly and those without proper heating are at the highest risk. Make sure they have a warm place to stay.
This Storm Should Not Be Underestimated
South Dakota has seen harsh winters before, but this storm is one of the most dangerous in recent years. With brutally cold temperatures, fierce winds, and heavy snow, the next few days could be a serious test for anyone caught unprepared. Take action now—stock up on supplies, limit travel, and stay indoors as much as possible. The worst is yet to come, and only those who are fully prepared will get through this storm safely. Stay warm, stay informed, and most importantly, stay safe.
