A couple of strong storms with gusty winds and hail remain possible this evening over southeast and east central New Mexico into a portion of west Texas, but the severe threat will remain marginal and should gradually diminish. ...Southeast New Mexico through west Texas... Overall trend has been for storms, including a few supercells, developing over the higher terrain and within upslope regime over southeast NM and southwest TX to gradually become less organized and weaken with loss of diabatic heating. The Midland 00Z RAOB indicates around 1000 J/kg MLCAPE and 46 kt sfc-6 km shear but modest (6.5-7 C/km) lapse rates and weak flow through the lowest 3 km. Isolated storms may continue through much of the evening, with a greater concentration probable within zone of frontal forcing from east central NM into a part of western TX. While a couple of storms could produce locally strong wind gusts and some hail, overall severe threat should gradually decrease. ..Dial.. 09/26/2017 Read more
