Forecasters are tracking a developing weather system that could trigger severe thunderstorms across parts of the Midwest this Sunday, with meteorologists warning of conditions favorable for hail and damaging winds.
A low pressure system is expected to move through Illinois and Indiana on Sunday, becoming the primary driver of severe weather through the afternoon and evening hours. The system is drawing in a strong surge of moisture from the south, a pattern forecasters say tends to fuel stronger storm activity.
This moisture is forecast to push northward across Missouri, Illinois, Indiana, and into Kentucky, raising humidity levels and atmospheric instability ahead of the storm system’s arrival. That combination is what meteorologists watch closely when assessing severe weather potential.
A corridor stretching from Missouri through southern Illinois and Indiana into Kentucky has been identified as an area of increasing risk. Surface temperatures in the upper 60s to low 70s are expected to pool across the region, creating conditions that could support storm development as the system advances eastward.
While the broader pattern is becoming clearer, specific details on storm timing, hail size, and wind speeds are still being finalized. Forecasters say those elements will likely come into sharper focus in updates over the next few days as Sunday approaches.
Residents across the four-state region are being urged to stay alert to forecast changes heading into the weekend, particularly those in the highlighted risk corridor. Severe weather in this part of the Midwest can develop quickly, and conditions can shift with little notice once the system moves in.
Local officials typically recommend having a way to receive emergency alerts, identifying a safe shelter location in advance, and avoiding travel during active storm warnings. Residents are encouraged to monitor official weather updates as the system approaches and to take any watches or warnings issued for their area seriously.
