||A persistent upper level ridge was oriented southwest/northeast from the eastern Pacific Ocean into the central U.S. plains. A persistent shear axis remained entrenched over much of central and eastern Texas. West Texas and southeastern New Mexico was sandwiched between these two features several days prior to June 23rd. At the surface, a trough situated from the Texas Panhandle extended west-southwestward into southwestern New Mexico, then south roughly along the Rio Grande River.
An upper level disturbance moved south between the aforementioned upper level features during the afternoon into a moderately unstable airmass. Thunderstorms developed in the afternoon over the higher terrain of eastern New Mexico and west Texas, and along the surface trough over the Texas Panhandle. Convection organized into a linear Mesoscale Convective System (MCS) by that evening over eastern New Mexico as it moved southeastward into a low level jet. The MCS began to bow southeastward as it moved into the southeastern New Mexico plains. Wind gusts as high as 61 kt were reported over Lea county.
