A tornado watch has been issued for Sunday afternoon and evening in the Pecos Valley of southwest Texas, as a powerful upper-level storm system rotates into the Southern Plains. A strong low-level jet, sufficient moisture, and cold air aloft will contribute to the explosive development of supercells. Given 0-1 km helicity values of 150+, tornadoes will also be possible with any isolated supercells.
As can be seen in the 21z RUC analysis below, the best 0-1 km helicity and CAPE is located over the central Pecos Valley, just south of the extreme southeast corner of NM. However, it is likely this favorable area for tornadoes will extend over the remainder of the S Texas Plains this evening. As can be seen in the surface wind barbs below in the CAPE map, a SSW to NNE surface boundary is also located across the western Pecos Valley. If a storm can move along this boundary, the low-level vorticity could be locally enhanced. We will keep you updated if any storms become tornadic in the next 4-6 hours.
