Arkansas Thunderstorms Cluster for 70 MPH Gusts, Quarter-Size Hail — SevereWX

Thunderstorms are firing across parts of southern and central Arkansas, northern Louisiana, and northeast Texas, with the risk of damaging wind gusts ramping up through the evening.

A weak surface boundary and low-level confluence are sparking storm development amid intense afternoon heating. Dewpoints in the lower 70s combined with steep midlevel lapse rates are fueling 3000-3500 J/kg of MLCAPE, setting the stage for strong downbursts. While deep-layer shear remains weak—favoring outflow-dominant storms—the focused ascent ahead of a midlevel low could lead to loosely organized clusters packing scattered 55-70 mph gusts and occasional 1.25-inch hail.

SPC's Mesoscale Discussion 1525 notes convective trends are under close watch, with a 40% chance of a severe thunderstorm watch. Storms should peak in the next few hours, primarily threatening populated areas in the AR/LA/TX corridor.

Key Threats:

• Winds: 55-70 mph (most probable peak)
• Hail: Up to 1.25 inches

Monitor radar closely if in the area—outflow boundaries may shift storms unpredictably. Check SPC's MD graphic for the latest outlook.

Preparedness Tip: Secure outdoor items, stay weather-aware via NOAA Weather Radio or apps, and have a shelter plan ready for sudden severe gusts.
