Todays weather in St. Louis MO - Sunday - 14 June 2026

St. Louis weather for today: a mild Sunday with a split personality. The morning carries a 23% chance of showers and thunderstorms — mostly before 10 a.m. — so commuters heading out early should keep an umbrella handy and a light layer within reach. Once that window passes, skies turn partly sunny and the afternoon settles in comfortably at a high near 78°F.Wind is out of the northwest at 8 to 14 mph, with gusts up to 23 mph — noticeable but not disruptive. Current conditions sit at 78 degrees as of this morning. Tonight looks genuinely pleasant: partly cloudy skies, a low around 58°F, and no precipitation. Northwest winds ease off overnight, making it a great night to sleep with the windows open.Looking ahead: Monday is flat-out sunny with a high near 79°F and calm winds — enjoy it. Tuesday climbs to 83°F before afternoon storm chances return after 1 p.m. Wednesday pushes toward 90 degrees and that's where things get more active. Storm chances climb through Wednesday night into Thursday, so if you have outdoor plans mid-week, now's the time to build in a backup.For today, the call is simple: umbrella for the morning commute, sunglasses for the afternoon. A fair trade for a Sunday in St. Louis.This episode includes AI-generated content.
