St. Louis is baking under dangerous heat today, Wednesday June 10, with a high near 95°F and a heat index as high as 101°F — keep outdoor plans to the morning hours, stay hydrated, and do not ignore the two-day severe weather window the National Weather Service has flagged starting this evening.
Today’s Setup
Mostly sunny with southwest winds of 6 to 12 mph and gusts to 21 mph. Lower humidity from downsloping off the Ozarks keeps conditions just below Heat Advisory criteria, but 101°F “feels like” is still dangerous. Forest Park, the Gateway Arch grounds, and any open exposed area become no-go zones from roughly noon to 6 PM CT. Get outdoor chores, a walk along the Katy Trail, or a morning at Creve Coeur Lake done before 10 AM CT. Check the St. Louis weather forecast for real-time updates throughout the day.
Severe Storm Threat: Tonight and Thursday
This is the story of the week. The National Weather Service is flagging two rounds of strong to severe thunderstorms:
- Tonight (Wednesday evening): Storms are possible with damaging wind gusts and large hail as the primary threats.
- Thursday afternoon and evening: A cold front arrives — and this is the bigger, more dangerous event. Forecasters explicitly warn of damaging wind gusts, large hail, and tornadoes. Thursday night carries a 90% chance of showers and thunderstorms between 7 PM and 1 AM CT, with wind gusts to 25 mph and temps dropping to near 68°F. The Weather Prediction Center has placed portions of the Midwest under a Slight Risk for excessive rainfall — storms capable of 2 to 3 inches per hour are in this setup.
Before Thursday hits, charge your battery backup phone charger, have a NOAA weather radio within reach, and consider staging a go bag emergency evacuation kit near the door. These are not overreactions for a Thursday-night tornado threat in St. Louis.
Heat and Fire Danger
Thursday’s combination of 96°F heat, wind gusts to 28 mph, and lowered humidity creates elevated fire weather conditions across the region. Keep a LED emergency flashlight and your go bag emergency evacuation kit accessible, and make sure any outdoor grills or fire pits are completely extinguished well before Thursday’s storms roll in.
Event Weather Watch
Tonight’s Joe Jackson + Band at The Pageant (June 10) is indoors — safe once you’re inside, but watch the radar before you leave.
Thursday’s Jamey Johnson at Chesterfield Amphitheater (June 11) is an outdoor show sitting right in the severe weather window. Get tickets on SeatGeek if you haven’t yet, but have a plan B and monitor conditions closely before heading out Thursday evening.
Friday looks dramatically better — high of 86°F and just 14% precipitation chance after the front clears. That makes outdoor shows like Billy Currington & Kip Moore at Saint Louis Music Park and “Weird Al” Yankovic at Ozarks Amphitheater (both June 12) far more manageable. Find tickets on StubHub for either.
Saturday brings Megan Moroney: The Cloud 9 Tour at Enterprise Center (June 13) — indoors, so no weather concerns. Rep the show in a Megan Moroney t-shirt or Megan Moroney hat. Looking further out, the St. Louis Cardinals host the San Diego Padres at Busch Stadium on June 15 — grab Official team gear on Fanatics before gameday.
Beat the Heat: Meal Idea
Skip the stove entirely today — a cold Thai noodle salad, a build-your-own wrap bar, or smoothie bowls are perfect for a 101°F heat index afternoon. A high-powered blender makes smoothie bowls fast and keeps the kitchen from heating up further. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
- Thursday: Peak of the heat wave at 96°F with a heat index near 107°F — then severe storms with tornado potential arrive in the evening. Take this seriously.
- Friday: Real relief — high drops to 86°F and storm chances fall to just 14% after the front sweeps through.
- Weekend: Warmer but calmer. Stay connected to local alerts as the pattern settles.
Browse outdoor gear deals ahead of the weekend, and make sure your phone’s weather alerts are active before tonight’s storm window opens.
