Missouri starts the day under a cool, gray sky, but a dramatic warm-up is already building across St. Louis and surrounding areas.
According to the National Weather Service, temperatures hover in the low 40s early with light north winds. Sunshine increases through late morning, pushing highs to around 54°F. Roads remain dry, but the brisk air keeps conditions feeling cooler during early travel.
Across the metro, including I-64, I-44, and I-70 corridors, the biggest shift comes over the next 48 hours. Temperatures surge into the low 60s Tuesday, then jump sharply to the mid-70s by Wednesday. By Thursday afternoon, highs approach 90°F, marking one of the warmest stretches so far this season.
This rapid warm-up reflects a broader central U.S. pattern, where temperatures climb 25 to 35 degrees above average. Residents will feel a quick transition from light jackets to short sleeves in just a few days.
A weak disturbance may bring a brief sprinkle chance late Tuesday, but most of the week stays dry. The next notable impact arrives late Thursday into early Friday, when showers and thunderstorms develop. Rain chances climb to around 70%, and wet roads could affect late-night travel.
Meteorologists note the sharp temperature swings could also stress infrastructure and increase fatigue for outdoor workers. Stay hydrated as heat builds and prepare for changing conditions late in the week.
For now, expect calm, warming days ahead with one eye on late-week storms. Are you ready for near-summer heat this early in spring?
