Scattered strong storms, a few possibly severe, will continue this evening from southwestern Texas toward the DFW Metroplex. Gusty winds and marginally severe hail are the primary threats. ...TX... Upper troughing has settled into the southwestern States this evening with one notable short-wave trough ejecting across the southern High Plains. This feature appears partly responsible for scattered convection that currently extends from the international border in Val Verde County, northeast across McCulloch into Erath County. This activity should continue to propagate slowly east this evening where buoyancy has yet to be overturned. 00z sounding from DRT exhibited 3000 J/kg MLCAPE while FWD was considerably less unstable if lifting an elevated parcel north of the frontal zone. Deep-layer flow appears sufficient for organized multicell updrafts and gusty winds and hail remain the primary threats. Over the next few hours the main corridor of strong convection should extend from north of DRT-Brady-FTW. ..Darrow.. 10/01/2021 Read more LIVE: spc.noaa.gov
