sweetapricity/bridgedeck-noaa huggingface dataset:
A developing strong 850-500 hPa zonal flow displaced well to the south of an anti-cyclonic feature in the northwest CONUS helped to develop convection across the region. Perturbations in the 700-500 hPa in the zonal west-east pattern developed convection off the high terrain of New Mexico. With good 700-500 mb flow of 30-50 kts in the afternoon of the 15th, this allowed the convection to be carried into the Panhandles region. With SBCAPE of 2000-3000 J/Kg along with strong effective shear approaching 50-60 kts, storms easily moved east into the Panhandles in a favorable environment. 00Z RAOB data from AMA showed also good direction shear of almost 180 degrees in the lower levels just out ahead of the convection. This lead to some storms rotating with brief funnels within some of the supercells. Damaging winds and large hail were Late report of trees up to 2 feet diameter being felled close to the trunk due to thunderstorm winds were produced with these storms before moving east out of the region very late on the 15th.
