After several days of chasing generally junky High Plains storms due to poor moisture and instability, we finally had a fairly decent chase setup on May 4th. \u00a0We had to get ourselves down from the Oklahoma Panhandle and into southwest Texas, though. \u00a0SPC liked the area from about Hobbs, NM, to Sanderson, TX, near the Rio Grande. \u00a0 I liked it, too! \u00a0Storms developed a little on the early side, near Pecos, while we were making our way south in the vicinity of Hobbs. \u00a0This discussion by SPC sets the stage nicely:<\/p>\n

A tornado watch was issued shortly after this mesoscale discussion went out. \u00a0We passed a cell near Hobbs that was electrically active and difficult to ignore, but I wanted to be farther to the south, in the better air. \u00a0Near Wink, I had to choose between a developing cell to our west and a bigger beast to the southwest. \u00a0Most chasers had their eyes on the supercell that was slowly moving east along Interstate 10, west of Fort Stockton. \u00a0But I wanted to give the one that was in western Loving County a chance. \u00a0We quickly found ourselves south of the storm base along U.S. 285, west of Mentone. \u00a0This supercell looked like a decent tornado candidate for 10 \u00a0minutes or so, but as it drifted to the ENE, north of Mentone, it began to shrivel up and weaken.<\/p>\n

It was not difficult to figure out what to do next. \u00a0We blasted down to Fort Stockton to get in front of the big HP beast which was swallowing up traffic along Interstate 10. \u00a0We made it to the town before the storm and squeezed in a pit stop and fuel fill-up.<\/p>\n

The Fort Stockton supercell tracked over the town as we watched on the south side along 285. \u00a0Hail with the storm was copious, with stone diameters to 2.5 inches. \u00a0We stayed out of that! \u00a0The storm had plenty of scary lowerings and splendid structure, but was perhaps a tad too out-flowy for a tornado. \u00a0We went back into Fort Stockton after the storm had cleared, and had to navigate through flooded streets. \u00a0It was getting dark by this time, and time to check into the motel after a long and interesting chase day.<\/p>\n","protected":false},"excerpt":{"rendered":"
