The St. Louis region is about to experience its first snowstorm of the 2024-2025 winter season this Saturday, with several inches of snow expected to blanket the northern portions of the area. Snow will begin early in the morning and continue through the day, impacting travel and everyday activities. The storm is forecasted to peak between 9 AM and 4 PM, so residents and commuters need to plan ahead for potentially hazardous conditions.
In this article, we’ll dive into the specifics of the storm, including expected snowfall amounts, areas likely to see rain instead of snow, and the safety precautions to take. Whether you’re braving the roads or simply preparing for the cold, this guide has everything you need to know about Saturday’s storm.
Key Weather Details for Saturday
The big weather story for Saturday is, of course, the snowstorm heading for the St. Louis region. Snow will begin falling early in the morning, moving from the northwest to the southeast. For those in the northern parts of St. Louis County and surrounding areas, it’s a full-on snowstorm. Snowfall rates will be moderate at times, especially between 9 AM and 4 PM, which is expected to be the peak period for snow accumulation.
While northern areas are set to see a proper snowstorm, things won’t be so wintery for areas south of a line from Rolla to Potosi to Perryville, Missouri. These regions are expected to get little to no snow, and instead, residents will likely see light rain. With temperatures hovering above freezing throughout the day, snow is unlikely to stick in the southern parts of the region.
Snowfall Amounts: What to Expect
For those expecting snow, here’s what you can anticipate:
- Along I-70/I-64: This corridor, including metro St. Louis, will likely see 2 to 4 inches of snow.
- Northwest of St. Louis: Some areas could see up to 5 inches, especially on cold, grassy surfaces.
- Surrounding areas: A broader swath of the region will see 1 to 2 inches, but the snow may accumulate more on untreated surfaces like sidewalks and roads.
It’s important to remember that temperatures on Saturday will be near or just below freezing, which means the snow could stick to untreated roads and highways. This could lead to hazardous driving conditions, particularly for those heading out during peak snowfall times. It’s a good idea to slow down, give yourself extra time, and stay safe.
Areas Likely to See Rain Instead of Snow
Not everyone will be digging out the snow shovels this weekend. For those in the southern parts of the St. Louis metro area, including cities like Rolla, Potosi, and Perryville, rain is more likely than snow. This is because temperatures in these areas are expected to stay above freezing for much of the day, preventing snow from forming.
While this region might miss the snowstorm, it’s important to be prepared for light rain and potentially slippery roads. Even rain can lead to slick surfaces, especially when it falls on already cold pavement. If you’re traveling through these areas, drive cautiously, and be aware that conditions can change rapidly.
Impact on Travel and Road Conditions
As the first significant snowstorm of the season moves in, it’s crucial for everyone to prepare for winter driving conditions. MoDOT (Missouri Department of Transportation) has already started preparations for the snowstorm. Crews will begin working overnight to treat state-maintained highways and roads, so you can expect to see plows and salt trucks working through the day.
However, even with the road treatments, it’s important to remain cautious. Snow can accumulate quickly, especially on untreated surfaces, making travel hazardous. Drivers are advised to slow down, leave extra space between vehicles, and avoid distractions like texting while driving. Bridges and overpasses can freeze faster than other roadways, so be especially cautious when driving over these elevated surfaces.

Winter Weather Advisory and Safety Precautions
A Winter Weather Advisory has been issued for the City of St. Louis from 6 AM to 6 PM Saturday. This advisory is in place to alert residents to the potential for hazardous weather conditions, particularly snow and ice accumulation on roads. If you have plans to be on the road, take extra precautions.
The National Weather Service suggests the following safety tips:
- Slow down and increase the following distance between your car and others.
- Pack emergency supplies in your vehicle, including blankets, extra clothes, and non-perishable snacks.
- Check road conditions before leaving home, especially if you’re traveling long distances.
What to Expect After the Snowstorm: Cold Weather and More
Once the snowstorm winds down Saturday evening, conditions will improve, but it’s not the end of the cold snap. Expect clear skies and a few lingering flurries, but Sunday and Monday will bring very cold temperatures. Wake-up temperatures will dip into the teens, and highs will only reach the low 30s. If you thought the snow was the worst part, brace yourself for even colder weather.
How the Cold Will Affect St. Louis
The drop in temperatures can be just as dangerous as the snow itself. With temperatures in the teens, it’s important to take precautions. Frostbite and hypothermia become more of a risk during extreme cold, so make sure you’re dressed in layers and avoid prolonged exposure to the cold.
The Impact on Local Events and Travel Plans
For those with travel plans or attending events this weekend, it’s a good idea to double-check your plans. The snowstorm and cold temperatures could impact holiday travel or outdoor gatherings. If you’re traveling, expect some delays, especially on major highways.
Preparing for the Season’s First Snowstorm
It’s always a good idea to be prepared for the first snowstorm of the season. Check your car’s tires, windshield wipers, and fluid levels. Make sure your home is stocked with essentials like food, water, and extra blankets, in case the cold snap lasts longer than expected.
Why This Snowstorm Is Different
While it’s common to get some early-season snow in St. Louis, this storm is noteworthy because it’s one of the stronger early snowstorms in recent memory. This is a good reminder that winter weather can hit hard and fast, even before December rolls around. Be sure to take this storm seriously and prepare accordingly.
Snow vs. Rain: What Happens When It Rains Instead of Snows
Some areas will see rain instead of snow due to warmer temperatures near the surface. This happens because the rain droplets freeze as they fall, creating slippery surfaces. So, while it might not be snowing in your area, icy conditions could still pose a risk.
Preparing for Future Snowstorms
It’s not just this snowstorm you need to think about—winter is just beginning. Make sure you’re prepared for future snowstorms by having snow removal tools ready, keeping your home winterized, and staying informed about upcoming weather events.
