Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0759 PM CDT Mon Aug 31 2020 Valid 010100Z - 011200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS CENTRAL/EASTERN OK AND NORTH TX... ...SUMMARY... Scattered severe thunderstorms remain possible this evening into tonight across Oklahoma and from southwest into northeast Texas. Damaging winds and large hail are the primary severe hazards. A tornado or two is also possible. ...01Z Update... ...Southern Plains... Recent surface analysis places a stalled cold front from southeast KS southwestward through southwest OK and adjacent northwest TX. Strong to severe thunderstorms have been ongoing for several hours ahead of this front across OK and into the TX Big Country. Low-level southerly flow will strengthen over the next several hours, and the expectation is for redevelopment to continue across this area as warm-air advection occurs across storm outflows. Wind profiles support organized storm structures and strong instability is expected to remain in place. As such, the potential for supercells will persist. Hail and strong wind gusts are the primary threat. A tornado or two is also possible, but the clustered storm mode and tendency for redevelopment over the same areas suggests storm interference is likely, limiting the potential for tornadogenesis. There is also some potential for eventual upscale growth into one or more organized convective lines but current radar trends suggest it could be several hours before this occurs. ...Elsewhere... A damaging wind gust or two remains possible across portions of the central Carolinas. Ongoing thunderstorms scattered across the Southeast are expected to gradually diminish over the next few hours as nocturnal stabilization continues. ..Mosier.. 09/01/2020Read more
