What looks like to me in the photos above is a landspout tornado that formed between about 5:15 PM and 5:30 PM MDT yesterday, between Carlsbad and the airport. Landspout tornadoes are fairly common in New Mexico. Whether all of these photos is of the same landspout, or if there were more than one, I really am not sure. I didn't see it so I can't say for sure. 

-------------------------------------------------------------

A landspout is a slang term coined by meteorologist Howard B. Bluestein in 1985 for a kind of tornado not associated with the mesocyclone of a thunderstorm.^[1] The Glossary of Meteorology defines a landspout as

"Colloquial expression describing tornadoes occurring with a parent cloud in its growth stage and with its vorticity originating in the boundary layer.

The parent cloud does not contain a preexisting midlevel mesocyclone. The landspout was so named because it looks like a weak Florida Keys waterspout over land."^[2]

Known officially as "dust-tube tornadoes" by the National Weather Service,^[3] they form during the growth stage of convective clouds by the ingestion and tightening of boundary layer vorticity by the cumuliform tower's updraft.

 Landspouts most often occur in drier areas with high-based storms and considerable low-level instability. They generally are smaller and weaker than supercellular tornadoes, though many persist in excess of 15 minutes and some have produced F3 damage.

 They bear an appearance and generative mechanism highly similar to that of waterspouts, usually taking the form of a translucent and highly laminar helical tube. Like waterspouts, they are also technically considered tornadoes since they are defined by an intensely rotating column of air in contact with both the surface and a cumuliform cloud. Not all landspouts are visible, and many are first sighted as debris swirling at the surface before eventually filling in with condensation and dust.
