568 ACUS01 KWNS 250100 SWODY1 SPC AC 250059 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0759 PM CDT Tue Sep 24 2024 Valid 250100Z - 251200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF CENTRAL/SOUTHERN OK... ...SUMMARY... A few severe storms remain possible this evening across parts of central and southern Oklahoma into north Texas. Strong to locally severe storms also remain possible across parts of the Ohio and Tennessee Valleys into the southern Appalachians region. ...Central OK into north TX... A hail-producing supercell that earlier moved through the OKC metro area has weakened, but additional development is underway across central OK. A cluster of strong to locally severe storms may continue southeastward into north TX through late evening, with moderate buoyancy and relatively strong deep-layer shear continuing to support a threat for at least isolated hail and damaging wind. Increasing CINH should eventually result in a weakening trend, though a few stronger elevated storms will remain possible into the overnight hours. ...Ohio/Tennessee Valleys into the southern Appalachians... Scattered thunderstorms are ongoing this evening across parts of the OH/TN Valleys into the southern Appalachians, within a relatively moist and favorably sheared environment. A gradual decreasing trend is expected to continue with time, due to diurnal cooling and weakening instability. However, ascent attendant to a mid/upper-level trough digging southeastward from the lower MO/mid MS Valley will help to sustain multicell clusters and possibly a couple supercells into late evening, with a threat of isolated damaging gusts and hail. ..Dean.. 09/25/2024 $$
