High-Based Storms Set to Unleash 75 MPH Gusts on Southern High Plains

Scattered to numerous thunderstorms are firing up across portions of the southern High Plains, where extreme heat and dry air are fueling a serious wind threat.

The NWS Storm Prediction Center's Mesoscale Discussion 1047 highlights portions of extreme northeastern New Mexico, far southeastern Colorado, the northern Texas Panhandle, Oklahoma Panhandle, and southwestern Kansas. With surface temps nearing 100°F and 50°F dewpoint spreads, low-level lapse rates exceed 9°C/km and DCAPE tops 1500 J/kg. This setup supports strong evaporative cooling, priming high-based storms for severe downdrafts.

Storms developing through late afternoon could produce gusts of 58+ mph, with some exceeding 75 mph. Deeper cells might also drop hail up to 1.75 inches. An approaching 500 mb trough will aid development, and SPC pegs the odds of a Severe Thunderstorm Watch at 80%.

Most probable peaks: winds 65-80 mph, hail 1-1.75 inches, and tornadoes up to 90 mph (though less likely with high bases).

This threat builds amid ongoing Plains activity, but focuses on gusty, pulse-style storms rather than organized supercells. Monitor radar closely as cells initiate.

Stay prepared: Have a severe weather plan, secure outdoor items, and seek shelter if storms approach. Check local NWS updates and apps for watches/warnings.
