Todays weather in St. Louis MO - Sunday - 28 June 2026

St. Louis is locked under an Extreme Heat Warning through July 3rd — and this is no ordinary summer hot spell. Today's heat index climbs as high as 109°F, with an actual air temperature of 94 degrees. Even overnight, the feels-like temperature could hit 110°F, offering little relief for anyone without air conditioning. If you have kids, elderly family members, or neighbors in vulnerable situations, today is the day to check in. The storm threat from early morning is fading fast, with skies clearing to sunny through the afternoon. Tonight stays warm with a low around 76°F, a mostly clear sky, and a south wind at 5 to 9 mph. Don't let the sunshine fool you — the danger is in the heat, not the clouds. Looking ahead, this isn't a one-day event. Monday reaches 96°, Tuesday climbs to 98°, and Wednesday holds at 97°. St. Louis is facing a sustained heat siege straight through Independence Day weekend, where the Fourth of July forecast sits near 95° with a slight afternoon storm chance. For your commute today: your parked car will be a furnace — give it time to cool before getting in. Wear light, loose clothing, drink water before you feel thirsty, and avoid outdoor activity during midday and early afternoon hours if you can shift it earlier or inside. This is a serious public health event. Stay cool, stay hydrated, and look out for each other, St. Louis. This episode includes AI-generated content.

St. Louis is under an Extreme Heat Watch through midnight Thursday, July 3rd — and this episode breaks down exactly what that means for your day, your commute, and the week ahead. Right now it's 86 degrees with a 30% chance of showers and thunderstorms. The best chance of rain falls before 7 a.m., with thunderstorms possible through early afternoon before skies partly clear by evening. Tonight stays unsettled with a 38% storm chance and a low around 73 — warm, humid, and worth planning around if you have anything outdoors after dark. Then the heat takes over. Sunday climbs to a high near 95 with heat index values reaching 113 degrees. Monday pushes to 97. Tuesday hits 98. The Extreme Heat Watch runs through Thursday morning, and mid-90s temperatures persist clear through next Friday. For your commute today, the morning window is the trickier stretch — wet roads and reduced visibility are possible if a storm cell moves through. Leave extra time and keep the drive calm. Afternoons clear enough to be manageable, but the humidity will make 86 feel heavier than it sounds. What to wear: light layers today that handle a quick downpour but breathe in the afternoon heat. Starting Sunday, go lightweight and loose — it's the only sensible answer for a week that looks like this. The heat index is the real story this week. The temperature alone is serious. The combination makes it dangerous. Stay hydrated, check on neighbors, and never leave anyone in a parked car. A YesWee production, built using AI technology.

St. Louis is under a Flood Watch until 7:00 PM this evening, and today's briefing covers everything you need to navigate it safely. Thunderstorms are already moving through the area with a 94% chance of precipitation — this is not a light rain day. The high reaches near 81 degrees with south winds of 5 to 9 mph, meaning the storm system is slow-moving and the heavy rain has time to accumulate.

Build extra time into any morning or midday travel, and remember: turn around, don't drown. Even shallow moving water can be dangerous. What to wear: skip the suede shoes and grab a rain jacket you can tie around your waist. It's warm and muggy, but a t-shirt alone won't hold up in a downpour. Tonight still carries a 65% chance of thunderstorms through the evening hours. The Flood Watch expires at 7 PM, but rain continues after. Expect a mostly cloudy night with a low near 68 degrees. Looking ahead, Saturday offers some sun before afternoon storm chances return. Then a major pattern shift arrives — Sunday climbs toward 94 degrees, and Monday could push 97. A serious heat stretch is building for next week.
