Severe Thunderstorm Outlook Warns of Potential EF-3 Tornadoes Across Mid-Mississippi Valley and Mid‑South

The National Weather Service’s Storm Prediction Center escalated its alert level Monday morning, issuing a Public Severe Weather Outlook warning that numerous severe thunderstorms could bring a dangerous mix of hazards across parts of the Mid-Mississippi Valley and Mid-South through the evening, including the potential for multiple strong to intense tornadoes. The outlook, issued at 7:52 a.m. CDT, said the threat could include EF-3 or stronger tornadoes, along with widespread damaging winds and very large hail.

The areas listed in the outlook were southern and central Illinois, central and eastern Missouri, western Kentucky, western Indiana, northern and central Arkansas, and western Tennessee. In the outlook, the Storm Prediction Center said the expected hazards included “several tornadoes, a couple intense,” “widespread damaging winds,” and “scattered large hail, some baseball size.” In its summary, the center warned: “Numerous severe thunderstorms are expected from the mid Mississippi/lower Ohio Valleys into the Mid-South through this evening, with a threat for multiple strong to intense tornadoes (EF-3+), widespread severe/damaging wind gusts, and scattered large to very large hail.”

A Public Severe Weather Outlook is a higher-profile, plain-language product the Storm Prediction Center uses when an especially significant or widespread severe weather event is expected. It is meant to alert the public early to unusually dangerous conditions and to emphasize the seriousness of the forecast before individual storms prompt more localized alerts.

The outlook is a forecast product, not a report that tornadoes or storm damage have already been confirmed. In severe weather terminology, a public outlook is a broad alert, a watch means conditions are favorable for dangerous weather, and a warning means a threat is occurring or imminent. If tornadoes do occur, any official Enhanced Fujita rating such as EF-3 would be assigned later through post-storm damage surveys.

The Storm Prediction Center urged residents in the threatened corridor to prepare before storms develop. “Review your severe weather safety procedures for the possibility of dangerous weather today,” the agency said. “Stay tuned to NOAA Weather Radio, weather.gov, or other media for watches and warnings.”
