Storms Expected This Week: Stay Alert

Midwest United States, USAMon Jun 15 2026
A weather warning has been issued for Wednesday, as a low‑pressure system moves over the Upper Midwest and Great Lakes. The shift will push winds southward into Mid‑Missouri, setting the stage for possible severe storms. Late Tuesday night, a cluster of storms could form near the cold front and travel northeast into Illinois. This activity may leave an outflow boundary that could spark more storms on Wednesday afternoon. The air south of the boundary will be hot and humid, creating an unstable environment that fuels powerful thunderstorms. Strong low‑level winds beginning late Tuesday will add moisture, while wind shear from the lower and middle layers supports rapid storm intensification.
If an outflow boundary is present, early afternoon storms could develop into isolated supercells capable of producing large hail and tornadoes. By the evening, a cold front will likely trigger a line of storms with damaging winds as the main threat. These storms are expected to move from north to south, fading after midnight. While isolated afternoon storms may pose various hazards, the primary concern for the evening will be strong winds and heavy rainfall. High atmospheric moisture could result in 1–2 inches of rain through Thursday morning. The Storm Prediction Center has placed most of Mid‑Missouri at a level 3 out of 5 for severe weather risk on Wednesday. Residents should stay informed and prepare accordingly.
