Southern Missouri Storms Ramp Up for 70 MPH Gusts, Golf Ball Hail — SevereWX

An ongoing cluster of thunderstorms in southern Missouri is showing signs of strengthening, raising the risk for isolated damaging wind gusts up to 70 mph and large hail around 1.75 inches (golf ball size) as it tracks east-southeastward.

SPC's Mesoscale Discussion 1121 highlights this activity downstream of a mid-level circulation (MCV) over southeast Kansas. Recent satellite and lightning data show increased lightning flashes and cooling cloud tops over the past hour, amid a destabilizing environment in northeast Arkansas and nearby areas with ample low-level moisture.

While high-resolution models struggle with the details, sufficient shear (25-30+ knots) supports potential for the cluster to persist and intensify through late afternoon. This could impact portions of the mid-Mississippi and lower Ohio Valleys, including southeast Missouri, southern Illinois, western Kentucky, and northeast Arkansas.

A Severe Thunderstorm Watch carries a 40% probability within the next couple hours if trends continue. Peak threats include 55-70 mph winds capable of downing trees and power lines, plus hail that could dent vehicles.

Stay alert if you're in the path—monitor local NWS updates and radar. Have a severe weather plan: identify a safe spot, charge devices, and secure outdoor items. Preparedness saves lives.
