J&J Storm Chasers | Missouri Severe Weather Update | Issued Sept 12, 2026
Missouri has a conditional severe-weather threat today, with the greatest concern currently focused across western and central portions of the state.
Western and Central Missouri -
A few strong to severe thunderstorms could develop today into tonight. The overall coverage remains uncertain, but storms that become severe could produce:
• Large hail
• Damaging wind gusts
• Frequent lightning
• Locally heavy rainfall
The National Weather Service currently has a Marginal Risk for severe thunderstorms across portions of western and central Missouri. Confidence in storm coverage and exact timing remains relatively low.
Northern Missouri -
The immediate widespread severe-weather threat appears limited, but isolated strong storms cannot be ruled out. Looking ahead, multiple rounds of thunderstorms could affect northern Missouri next week, bringing the potential for significant cumulative rainfall.
Southern Missouri -
The Missouri Ozarks have a Marginal Risk for severe storms, particularly west of Highway 63. Large hail and damaging winds are the primary severe threats. Extreme heat will also remain a concern, especially where storms do not develop.
Looking Ahead -
The bigger concern may develop next week as repeated rounds of showers and thunderstorms become possible across Missouri. Some areas, particularly northern Missouri, could see several rounds of rainfall and potentially heavy cumulative totals.
South of the heavier rainfall corridor, temperatures could climb back into the low to middle 90s.
Today’s threat is NOT expected to be a widespread, high-confidence severe-weather event across the entire state. However, the environment could still support isolated severe storms, so localized impacts are possible.
The forecast will likely become clearer as storms develop and additional data comes in.
We will continue monitoring Missouri weather conditions, radar trends, warnings, and forecast changes throughout the day.
Have multiple ways to receive warnings and stay weather aware.
