SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0755 PM CDT Sat Sep 23 2017 Valid 240100Z - 241200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE SOUTHEAST NEW MEXICO/FAR WEST TEXAS AREA...... ...SUMMARY... Isolated strong/severe storms -- capable of producing locally damaging wind gusts and marginal hail -- may persist for another few hours across parts of southern High Plains including far West Texas. ...Southeast New Mexico and far West Texas and vicinity... While a broad convective band extending from the north-central U.S. south-southwest to far West Texas persists, overall/gradual weakening of the convection continues with a combination of diurnal cooling/stabilization, and outflow largely undercutting storms across the northern and central U.S. The most vigorous storms are ongoing across southeast New Mexico and far West Texas at this time. In this area, ample instability (1000 to 1500 J/kg mixed-layer CAPE per objective analyses) and ample deep-layer shear indicated across the area will continue to support limited hail/wind risk. Eventually, stabilization of the boundary layer should result in a gradual ramp-down of convective organization, but marginal severe risk may linger for the next 2-3 hours or so. ..Goss.. 09/24/2017 Read more
