St. Louis, Missouri – Severe storms could move into the St. Louis area after midnight Monday, bringing the potential for damaging winds, large hail, and isolated tornadoes into early Tuesday morning.
According to the National Weather Service in St. Louis, Monday’s severe threat is primarily focused north and west of the city. However, the risk grows locally after midnight, with strong to severe storms possible through daybreak. Thunderstorms could produce hail over two inches in diameter, wind gusts topping 60 mph, and heavy rain along major corridors such as I-70 and I-64.
Residents across St. Charles, Jefferson, and Franklin counties should prepare for rapidly changing conditions overnight. Emergency managers advise securing loose outdoor objects, ensuring mobile devices are charged, and having multiple ways to receive weather warnings. If traveling early Tuesday, motorists should expect possible delays or hazardous conditions on major highways.
This system is part of a broader severe weather outbreak impacting the Upper Midwest, similar to late April storm patterns seen in recent years. Additional watches and warnings could be issued overnight as storms develop.
Severe weather threats in eastern Missouri are expected to taper by mid-morning Tuesday, but residents should stay alert for updates throughout the night.
