St. Louis, get ready to experience four seasons in just a few days! This week’s forecast will take us from frigid, frosty mornings to mild, almost spring-like afternoons—and even a chance of rain thrown in for good measure. If you’ve been waiting for warmer temperatures, they’re on the way, but not before another round of cold mornings and sharp temperature swings.
Right now, it’s clear and freezing at 28°F (-2°C), but by next week, temperatures could soar into the 70s—a huge difference in just a matter of days. The biggest challenge? Dressing for this unpredictable weather. In the mornings, you’ll need a heavy coat, but by afternoon, a light jacket or even short sleeves might be enough. If you’re not a fan of the cold, just wait a few hours—it won’t last long
What’s Causing This Dramatic Shift?
A fast-moving weather pattern is sweeping through Missouri, bringing cold air at night but allowing warmer air to build in the afternoons. This clash of temperatures is typical for early March in St. Louis, but it still catches people off guard every year.
The biggest takeaways:
- Mornings will start off freezing, with temperatures in the 20s and 30s.
- Afternoons will feel completely different, with highs in the 50s, 60s, and even 70s by early next week.
- A chance of rain arrives Friday afternoon, bringing cooler air for Saturday.
- Next week looks like a spring preview, but another cooldown could be just around the corner.

How This Weather Shift Will Affect You
- Layer Up! Mornings will be freezing, but afternoons will feel like spring. Wear layers that you can easily remove throughout the day.
- Watch for Friday Showers. While it won’t be a washout, light rain is possible in the afternoon and evening. If you’re heading out, bring an umbrella just in case.
- Be Ready for Changing Road Conditions. Icy patches could be an issue early in the mornings, especially on bridges and overpasses. By afternoon, roads should be completely dry.
- Warm Air Could Bring a Springlike Feel, But Don’t Be Fooled. Just because it’s warm next week doesn’t mean winter is over! March is known for sudden cold snaps, so don’t pack away the winter gear just yet.
- Enjoy the Sunshine While It Lasts. After weeks of gloomy skies, this stretch of sunshine will feel amazing. Take advantage of it with outdoor activities before the next system moves in.
Final Thoughts
St. Louis is in for a wild week of weather, with freezing mornings, warm afternoons, and a little bit of rain thrown in for good measure. By early next week, highs will push into the 70s, giving us a true taste of spring!
But don’t be fooled—Missouri weather changes in the blink of an eye. Enjoy the sunshine while it lasts, but keep an eye on the forecast for the next big shift
