A major winter storm is on track to hit St. Louis, bringing significant snowfall and an Arctic blast that could make this one of the most brutal weeks of winter so far. The National Weather Service has issued a Winter Storm Watch, warning that conditions will become hazardous with accumulating snow, strong winds, and dangerously low temperatures.
With the potential for up to 10 inches of snow, bitter wind chills, and subzero overnight lows, residents should prepare now for what could be a major disruption to daily life.
How Much Snow Will St. Louis Get?
Forecasters are closely watching the incoming storm system, which has the potential to dump 4 to 10 inches of snow across the St. Louis metro area. Areas just south of the city could see even higher totals depending on how the system moves.
One of the biggest concerns is that this will be a dry, powdery snow, meaning even a small amount of precipitation could result in deeper accumulations. Typically, one inch of water produces 10 inches of snow, but with the extreme cold, that same moisture could result in 15 to 20 inches in some spots.
If you need to run errands or stock up on essentials, it’s best to do so before Tuesday, as roads are expected to become slick and dangerous.
Frigid Temperatures Will Make Conditions Even More Dangerous
Snow isn’t the only concern—bone-chilling temperatures and Arctic wind chills will create dangerous conditions throughout the week.
- Monday, February 17 – A cold start with light snow possible in the morning. High temperatures will struggle to reach 22°F (-5°C).
- Tuesday, February 18 – The storm intensifies, bringing steady snowfall throughout the day. High temperatures will only reach 14°F (-10°C), with wind chills making it feel even colder.
- Wednesday, February 19 – One of the coldest days of the winter, with a high of 16°F (-9°C) and overnight lows plunging to -1°F (-18°C).
- Thursday, February 20 – Bitter cold lingers with highs around 15°F (-9°C), but a slight break from snowfall.
- Friday, February 21 – A gradual warm-up begins, with highs in the upper 20s, but still well below normal for this time of year.
Wind chills throughout Tuesday and Wednesday could make it feel as cold as -15°F (-26°C), increasing the risk of frostbite and hypothermia for anyone exposed to the elements for too long.
How Will This Storm Impact St. Louis?
With heavy snow and extreme cold, this storm could cause major disruptions across the city.
- Travel Will Be Hazardous – Snow-covered roads, icy conditions, and reduced visibility will make driving treacherous. If you don’t have to go out, stay home.
- Flight Delays and Cancellations Likely – St. Louis Lambert International Airport could see delays or cancellations, so travelers should check with their airlines before heading to the airport.
- Power Outages Are Possible – Heavy snow and strong winds could bring down tree limbs and power lines, so residents should have backup heating options and emergency supplies ready.
- Frostbite and Hypothermia Risk – With temperatures dropping below zero, prolonged exposure can be life-threatening. Anyone who must go outside should wear layers, gloves, hats, and cover all exposed skin.
How to Prepare for the St. Louis Winter Storm
With dangerous conditions expected, here are some key steps to take now to ensure you stay safe:
- Stock Up on Essentials – Grocery stores and gas stations may become overwhelmed before the storm, so get food, water, and supplies early.
- Prepare for Power Outages – Have flashlights, batteries, blankets, and alternative heat sources ready in case of an emergency.
- Protect Pipes from Freezing – Open cabinets under sinks, let faucets drip, and insulate exposed pipes to prevent them from bursting.
- Check on Elderly or Vulnerable Neighbors – Those without reliable heating or transportation may need assistance before the storm hits.
- Stay Off the Roads If Possible – Snow-covered streets and strong winds will make driving extremely dangerous. If you must drive, go slow, keep extra distance, and carry an emergency kit in your vehicle.
When Will St. Louis Warm Up Again?
The worst of the storm will last through Thursday, but bitter cold temperatures will stick around into the weekend.
By Sunday, February 23, temperatures may finally climb back above freezing, with highs in the mid-30s to low 40s expected next week. However, snow and ice will take time to melt, so slick roads and freezing overnight temperatures could linger for several days.
Final Thoughts: Prepare Now, Stay Safe, and Stay Warm!
This winter storm is shaping up to be one of the most intense of the season, with heavy snow, frigid temperatures, and dangerous wind chills combining to create life-threatening conditions.
St. Louis residents should take this storm seriously, make preparations now, and stay indoors whenever possible once the snow and extreme cold arrive.
