High Plains Severe Threat Builds: 80 MPH Winds, Golf Ball Hail Possible

Storms igniting over the Rockies and High Plains are ramping up fast this afternoon, putting a broad swath from eastern Wyoming through northeast Colorado, southwest South Dakota, the Nebraska Panhandle, far northeast New Mexico, the Oklahoma and Texas Panhandles, and southwest Kansas at risk for severe weather. The Storm Prediction Center (SPC) has issued two Mesoscale Discussions (MDs) highlighting this growing danger, with a 60% chance of severe thunderstorm watches in both areas.

In the northern zones—eastern Wyoming, northeast Colorado, far southwest South Dakota, and the Nebraska Panhandle—thunderstorms are bubbling up along the Colorado Front Range and northeast Wyoming. These storms are poised to push into the High Plains amid steep lapse rates and 1,000-1,500 J/kg of MLCAPE. With 30-40 kt of wind shear, expect multicell clusters and some supercells producing 1-1.75-inch hail initially, transitioning to 55-70 mph wind gusts as they upscale this evening.

Farther south and east, along the Sangre de Cristo Mountains and Raton Mesa, new storms are firing near a warm front stretching into the Oklahoma/Texas Panhandles and southwest Kansas. Here, even richer instability (1,500-2,500 J/kg MLCAPE) supports clusters capable of 70-80 mph gusts as the main threat. Models hint at these regimes merging over southwest Kansas tonight, amplifying the severe wind potential.

What’s a Mesoscale Discussion? For everyday folks, an MD is the SPC’s early alert: severe thunderstorms are developing on short timescales (1-6 hours) in a specific area, and a watch—meaning conditions favor widespread severe weather—could drop soon. Keep an eye on radar and local NWS updates.

Peak hazards include quarter-to-golf ball hail and damaging straight-line winds that could down trees, power lines, and cause outages. Stay prepared: Charge devices, secure outdoors, have a safe room ready, and monitor warnings via NOAA Weather Radio or apps. High Plains, buckle up—this could get rowdy into evening.
