Upslope flow in eastern New Mexico underneath yet another disturbance exiting the southwestern US setup a pattern marginally favorable for supercells. One did develop northeast of Roswell, NM and drifted northeastward towards Hobbs and Tatum.
The storm became supercellular rapidly and went through several stages quickly. This view towards the due north shows the original, occluded mesocyclone in the far background, with a rain curtain wrapping around its north and west side. A new rain free base was developing directly overhead.
This storm eventually linked up with other storms in the area to form a raging squall line which slammed the Lubbock, TX area around midnight. A tornado was reported with this storm before it linked with the others, after sunset and about 15 minutes after we left it (sigh).
