Missouri – Warm air is already rising over St. Louis this morning, and the pavement feels dry now, but changes are lining up fast as storms organize to the west. Temperatures climb quickly into the mid-80s, creating a summer-like setup that will fuel stronger storms within the next 24 to 36 hours.
According to the National Weather Service, St. Louis will reach near 84°F today with southwest winds increasing to 10 to 17 mph and gusts up to 32 mph. That added wind energy and moisture will help trigger scattered thunderstorms by Tuesday afternoon, with rain chances increasing sharply into the evening.
By Tuesday evening, storms may become more widespread across both Missouri and Illinois sides of the metro, including St. Louis, Clayton, and Belleville. Rain chances rise to 70%, and brief heavy downpours could reduce visibility along I-64, I-70, and I-44. Plan extra travel time and watch for sudden slowdowns.
The pattern intensifies midweek. Wednesday brings an 80% chance of rain and thunderstorms, with repeated rounds possible. Wet roads and ponding water may impact the morning and evening commutes. Localized flooding cannot be ruled out in low-lying areas.
Storm chances remain elevated into Thursday, with another 80% chance of rain and possible thunder. Temperatures cool slightly into the upper 70s, but humidity stays high, keeping conditions unsettled.
Looking ahead, early April trends warmer again, but this active storm track could bring additional alerts. Keep devices charged and stay weather-aware as conditions evolve quickly.
