SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0741 PM CDT Wed Sep 29 2021 Valid 300100Z - 301200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF NORTH-CENTRAL/CENTRAL TEXAS... ...SUMMARY... A few strong/locally severe storms remain possible across parts of northern/central Texas for the next couple of hours. Gusty winds and hail remain the primary threats. ...Southern Plains... Early-evening water-vapor imagery depicts a short-wave trough stretching from western OK into north-central TX. This feature is ejecting northeast across the southern Plains and appears to be partly responsible for scattered convection that developed earlier this afternoon, which continues at this time from central TX into northwestern OK. 00z sounding from FWD exhibits modest instability with steep low-level lapse rates. While deep-layer shear is not that strong, adequate buoyancy continues across north-central/central TX for robust updrafts to persist for the next couple of hours. Lack of strong inflow into this activity, along with the ejecting short wave, suggest any boundary-layer cooling should contribute to weakening convection by 03-04z. ..Darrow.. 09/30/2021 Read more LIVE: spc.noaa.gov
