St. Louis – Light rain showers dotted the region overnight, clearing out to reveal partly cloudy skies on Tuesday. Residents woke to milder conditions as temperatures climbed into the mid-60s during the day. Forecasters predict a rapid warm-up through mid-week, culminating in near-record heat, only for thunderstorms to introduce a cooler air mass late in the week.

Overnight Showers Yield to Milder Tuesday

Spotty precipitation moved through the St. Louis area late Monday into early Tuesday, leaving behind damp grounds but no major disruptions. Skies transitioned to partly cloudy as the morning progressed, allowing sunshine to boost daytime highs.

Temperatures reached the mid-60s Tuesday afternoon, a noticeable jump from recent cooler patterns. Winds remained light, contributing to comfortable outdoor conditions. This shift marked the start of a broader warming trend across the Midwest.[1]

Wednesday’s Surge Pushes into the 70s

Morning lows dipped into the 40s Wednesday, providing a crisp start before another round of heating. Daytime highs soared well into the 70s under mostly clear to partly cloudy skies, offering a taste of spring warmth.

A few isolated showers could develop overnight into Thursday morning, but they posed minimal threat. Breezes picked up slightly, stirring the air as humidity levels began to rise. Outdoor activities benefited from the pleasant conditions, though pollen counts likely increased with the sun.[1]

Thursday Delivers Scorching Conditions for Cardinals Home Opener

The warm-up peaked Thursday with breezy and hot weather dominating the forecast. Temperatures approached 90 degrees Fahrenheit, challenging the daily record high of 87 degrees. Fans heading to Busch Stadium for the Cardinals’ home opener enjoyed ideal baseball weather during the day.

Strong southerly winds fueled the heat, pushing humidity higher and creating a summer-like feel. No widespread rain interrupted the action, though scattered clouds added variety to the sky. This brief heat episode highlighted the region’s volatile spring patterns.[1]

Storms and Cool-Down Arrive Late Week
