St. Louis residents can expect summer heat to make a comeback this week, with highs climbing toward the 90s starting Tuesday. Afternoon commutes along I-70 and I-64 may feel more like July than September, raising concerns for drivers and outdoor workers.
According to the National Weather Service in St. Louis, temperatures will rise to around 83 on Tuesday, then spike into the upper 80s Wednesday. By Thursday, the region will see highs near 94, with little chance of relief from rain. Calm winds will provide minimal cooling, and nighttime lows will stay in the 60s and 70s, limiting overnight comfort.
The heat could stress vulnerable populations, especially those without reliable air conditioning. Residents are urged to stay hydrated, limit strenuous outdoor activity in the afternoon, and check on elderly neighbors. Public transit riders in St. Louis should prepare for longer waits in direct sun.
While skies remain mostly sunny through the week, the stretch of hot, dry weather may dry out soils quickly across Missouri. Outdoor events and school sports in the St. Louis metro should plan for above-normal heat during practices and games through the weekend.
The pattern holds into early next week, with no strong signs of rain relief. Authorities warn that additional air-quality alerts may be issued if stagnant conditions worsen.
