St. Louis is waking up to mostly cloudy skies this Wednesday with a slight chance of rain showers and a high near 62°F—mild spring weather that’s perfect for getting outdoors later in the day, though you’ll want to keep an umbrella handy just in case.

Today’s Setup

Overnight into early morning, there’s only a 16–20% chance of rain showers, so most of us will stay dry as we head into Wednesday. Temperatures are hovering around 45°F with light northwest winds around 2 mph. By mid-morning, clouds will begin to break apart, and we’ll see partly sunny conditions develop across the city—from Forest Park to the Gateway Arch downtown. High temperatures will reach near 62°F with winds staying light at 2 to 8 mph from the northwest.

Cardinals Game & Tailgating

If you’re heading to Busch Stadium for the St. Louis Cardinals vs. Milwaukee Brewers on Wednesday, you’re in luck with the weather. Conditions will be ideal for a ballgame—partly sunny skies, mild temps in the low 60s, and minimal rain risk. Grab a St. Louis Cardinals jersey or St. Louis Cardinals fitted cap to show your support, and consider Get tickets on SeatGeek or Find tickets on StubHub if you haven’t secured yours yet. Tailgating conditions will be pleasant; bring a hard cooler 52 quart stocked with cold drinks, and a picnic basket set for 4 if you’re making an afternoon of it in the lot.

Best Window To Be Outside

After 10 AM through early evening is your sweet spot. The sun will peek through the clouds, and with temperatures climbing into the upper 50s and low 60s, it’s a great day to take a walk along the Riverfront or spend time at Tower Grove Park. Light winds mean kites will fly sluggishly, but it’s perfect for a leisurely stroll or outdoor lunch. By evening, conditions remain dry and pleasant—mostly clear skies move in after sunset.

What To Wear Or Bring

Layer up this morning with a light jacket or sweater; you’ll shed it by afternoon as temps rise. Sunglasses are optional given the partly cloudy pattern, but an umbrella or rain jacket is smart insurance—that 16% rain chance is low, but spring showers can sneak up. If you’re planning evening outdoor activities, bring a hammock with stand and settle in under clear skies after 6 PM CT.

Tonight & Thursday Outlook

Wednesday night turns mostly clear with a low around 44°F and calm winds. Thursday looks even better—sunny skies and a high near 67°F with barely any wind. It’s shaping up to be one of the nicest days of the week.

Rainy Day Comfort (Just In Case)

If those rain showers do materialize this afternoon, embrace cozy indoor time with slow-cooker chili or beef stew simmering away. A programmable slow cooker or enameled cast iron Dutch oven makes prep effortless—set it and forget it while you handle the day. You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Thursday is your standout day—sunny, 67°F, and dry. Friday night into the weekend, watch for a warming trend as we head into May. Stay tuned to St. Louis weather forecast for updates as the pattern evolves.
