900 ACUS11 KWNS 242217 SWOMCD SPC MCD 242216 TXZ000-242345- Mesoscale Discussion 0958 NWS Storm Prediction Center Norman OK 0516 PM CDT Sat May 24 2025 Areas affected...Parts of west TX Concerning...Severe potential...Watch possible Valid 242216Z - 242345Z Probability of Watch Issuance...40 percent SUMMARY...Isolated severe storms are possible into this evening, with potential for localized severe gusts and hail. DISCUSSION...High-based storm development is underway across parts of the TX Trans-Pecos and Big Bend regions, within a hot and well-mixed environment. WV imagery suggests that a weak shortwave trough is moving across southeast NM and west TX, which may aid in additional storm development into the early evening. Within the high-based regime into parts of the Permian Basin and South Plains, where dewpoints are in the 40s-50s F and temperatures have generally increased above 100 F south of a quasi-stationary front, MLCAPE has increased into the 500-1500 J/kg range. Deep-layer flow/shear is generally weak, but at least transient vigorous storms are possible, with a threat of localized downbursts and perhaps some hail. Farther northeast into parts of the Big Country and northwest TX, MLCAPE has increased above 2000 J/kg along/ahead of a diffuse moisture gradient/dryline, with dewpoints increasing through the 60s F. Some building cumulus is noted from northwest of San Angelo to southeast of Childress, and isolated storm development is possible within this region into this evening. Somewhat backed low-level flow east of the diffuse dryline will support relatively stronger deep-layer shear, with some potential for organized multicells and perhaps a supercell or two if deep convection can mature in this region. Large hail and isolated severe gusts would be the most likely hazards within this regime, though a tornado cannot be ruled out if any supercell can persist into the increasingly moist environment east of the diffuse dryline this evening. ..Dean/Mosier.. 05/24/2025 ...Please see www.spc.noaa.gov for graphic product...
