St. Louis weather today is sunny and pleasant, with highs near 69°F and light southwest winds of 0 to 10 mph—a perfect setup after a chilly morning in the low 40s. This is your golden ticket to get outside before a rainy Friday arrives, so don’t waste it.
Today’s Setup
After a mostly cloudy overnight with lows around 41°F, abundant sunshine and warming air will push temperatures steadily upward through this afternoon. Southwest winds will gust as high as 21 mph, but that’s nothing that’ll ruin your plans—it’ll just keep you feeling fresh. The National Weather Service forecasts a dry day areawide, with zero chance of precipitation, so you can leave the umbrella at home.
Best Window To Be Outside
Head to Forest Park, the Gateway Arch grounds, or your favorite neighborhood park between now and sunset. This is the best day of the next three to enjoy St. Louis’s outdoor spaces.

Golfers and outdoor enthusiasts should take advantage of the calm, sunny conditions; Friday’s rain chances jump to 80 percent by afternoon.
Rain, Wind & Severe Weather Risk
Tonight stays mostly clear with lows around 50°F, but Friday brings a significant shift. A weak cold front will push through Friday morning, and by afternoon (between 2 PM and 5 PM CT), showers and thunderstorms will become likely along the boundary. The National Weather Service notes that atmospheric instability will increase as moisture pools in from the southwest, with CAPE values reaching 1000–1250 J/kg—enough to spark some organized convection. No severe weather is expected, but rain coverage will be widespread by late afternoon. Plan indoor activities for Friday if you prefer to stay dry.
What To Wear or Bring
Layer up this morning—it’s chilly at 41°F—but by midday, you’ll be comfortable in a light jacket or long sleeves. Sunscreen and sunglasses are essential; the sun will be intense. If you’re heading to tonight’s Stifel Stars on Ice at Enterprise Center or catching Frankie Valli & The Four Seasons: The Last Encores at The Factory, you’ll have clear skies for your commute. For Friday’s St. Louis Battlehawks game against Columbus Aviators at The Dome at America’s Center (an indoor venue, so no weather worries), grab Official team gear on Fanatics to show your support, and if you’re tailgating beforehand, bring a portable propane grill and plan for setup before the storms roll in around 2 PM CT.
Dinner & Grilling Ideas
Tonight is perfect for grilling. Fire up the backyard for burgers, steaks, or chicken—you’ll have clear skies and comfortable conditions through sunset. If you’re planning a casual weeknight dinner, a simple grilled pasta with fresh vegetables pairs well with the mild evening. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door. Consider picking up Amazon Fresh groceries for any last-minute items.
Next Few Days
Friday will warm to 76°F before afternoon showers and thunderstorms take over between 2 PM and 5 PM CT—a 78 percent chance of rain. Saturday will see continued warm air (upper 70s to low 80s) with another round of storm chances, then a cold front will sweep through late Sunday, dropping temperatures back into the 50s and 60s by early next week. Make the most of today’s sunshine—it’s the best day of your week.
