St. Louis is looking at a sunny and warm Thursday with a high near 84°F, but don’t let that fool you—a significant round of showers and thunderstorms is heading our way late tonight.
Today: Make the Most of the Sunshine
This morning starts mild around 59°F, and it’s the perfect window to tackle outdoor tasks. If you’ve been meaning to mow the lawn or apply lawn fertilizer spring before things get wet, do it now. South winds will gust between 25 and 28 mph at times, so secure anything loose in your yard—trash cans, patio furniture, and garden items should be battened down.
The St. Louis Cardinals vs Seattle Mariners game at Busch Stadium on Friday will be impacted by tomorrow’s storms, but today’s weather is ideal if you’re planning any outdoor activities along the Gateway Arch grounds or in Forest Park. Grab a portable bluetooth speaker and enjoy the afternoon—just know the winds will pick up as we head toward evening.
Tonight & Friday: Significant Weather Arrives
Here’s where it gets serious. High confidence (80–90%) from the National Weather Service indicates that widespread showers and thunderstorms will develop after 2 AM CT and continue through Friday morning. A large but decaying thunderstorm complex is moving in, and while the overall severe weather threat is low, isolated damaging wind gusts remain possible. The Storm Prediction Center is monitoring the situation, and the Weather Prediction Center notes a marginal risk of excessive rainfall across the region—flash flooding isn’t expected to be widespread, but localized heavy rain rates could exceed 1 inch per hour at times.
Friday will see showers and thunderstorms before 1 PM CT, with a 80% chance of precipitation. Highs will only reach 74°F—a sharp drop from today. If you’re heading to the St. Louis Cardinals vs Seattle Mariners game Friday at Busch Stadium, bring an umbrella and consider wearing a pollen count face mask if you’re allergy-prone; the wet pattern and wind shifts often trigger allergies. For tailgating, keep it covered and grab some Claritin non-drowsy allergy medication just in case.
For those attending events like the Psychology of Serial Killers theater show at The Pageant on Friday or Chelsea Handler’s comedy tour at The Factory on Friday, plan for wet conditions getting to and from venues.
Allergy Alert
With the warm southerly winds and moisture surge ahead of tonight’s storms, pollen counts will spike. Keep an allergy relief nasal spray handy, and if you’re sensitive, a HEPA air purifier in your bedroom will help you sleep better through the night as storms roll through.
Dinner Suggestion
With wet weather moving in, skip the grill and prepare a comforting pasta or stir-fry indoors. You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door—grab some fresh Amazon Fresh groceries and a live herb plant collection to keep basil and oregano on hand for quick weeknight meals.
Looking Ahead
Saturday clears out with cooler temps in the low 50s. Another round of showers and thunderstorms remains very likely late Sunday through Monday, so stay tuned to your NOAA weather radio for updates. The wet pattern continues through the weekend, so plan indoor activities—board games and family card game sets are perfect for rainy days with the kids.
