A potent upper level storm system approaching New Mexico from the west interacted with deep moisture and very unstable conditions along a sharp dryline over eastern New Mexico on May 26, 2019. Dry showers and thunderstorms with strong downburst winds first developed along the Continental Divide by late morning before marching east into the Rio Grande Valley through the afternoon. Several locations within the Rio Grande Valley reported wind gusts in excess of 60 mph, including Los Lunas, Albuquerque, Santa Fe, and Taos. Wind damage was also reported as this activity moved across the central mountain chain into the Estancia Valley. Meanwhile, showers and thunderstorms fired up along the dryline in eastern New Mexico then quickly became severe with large hail, high winds, and several tornados. A violent supercell thunderstorm that moved through Union County during the late afternoon produced at least two tornadoes and three inch hail. Severe thunderstorms then evolved into a quasi-linear convective system over the Caprock region and resulted in a large area of high winds and large hail. Several more tornadoes developed along the southern edge of this line, including a spectacular wedge tornado near Dora. In addition to all the severe thunderstorms that impacted the region, many areas outside of thunderstorm activity in central and western New Mexico also reported strong southwest winds with gusts of 50 to 60 mph.

A storm chaser observed a tornado to the northwest of Clayton.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:56 UTC.

37 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
