St. Louis – Residents recently enjoyed milder weather, but a notable warm-up is underway. Temperatures climb higher midweek, with Thursday bringing the hottest conditions of the week. Storms will follow late Thursday, signaling a sharp shift to cooler air.[1]

Wednesday’s Sunny Surge Sets the Stage

Conditions turn mostly sunny to partly cloudy today. Highs reach near 80°F, marking a 20-degree jump above seasonal averages. This represents a 15-degree increase from Tuesday’s highs.

Overnight lows remain mild in the 60s. Such warmth accelerates the buildup toward peak heat. Residents notice the rapid change after cooler recent days.[1][2]

Thursday Brings Record-Challenging Heat

The Cardinals home opener coincides with breezy, hot weather. Temperatures top out around 90°F. Winds pick up, adding to the summer-like feel.

Historical benchmarks loom large. The warmest first-pitch temperature stands at 85°F from 2001. March 26’s record high is 87°F, set in 1991. St. Louis’s all-time March peak hit 92°F on March 24, 1929. Forecasters see potential to surpass these marks.[1]

Thunderstorms Threaten Late Thursday

The system delivers a stark cooldown. Friday highs dip to the low 50s, with morning showers possible. Saturday mornings near freezing mark the chilliest start in days.[1]
