Wider weather episode

An area of high pressure remained centered over Nevada, but abundant moisture and moderate instability across New Mexico provided the necessary ingredients for a round of numerous showers and thunderstorms on July 11, 2021. Sufficient deep layer shear also was supportive of organized thunderstorm development and large hail. Thunderstorms initially formed over the high terrain areas with outflow allowing thunderstorms to move onto lower elevations. Several reports of hail were received across eastern New Mexico with a couple thunderstorms producing two inch hail. Meanwhile, flash flooding was once again a concern, especially in south central New Mexico where soils were primed from previous days of heavy rainfall. The most significant flash flooding of the day was reported in Roswell where numderous roadways, yards, and ditches were flooded.
