Valid 061106Z - 061230Z The severe weather threat for Severe Thunderstorm Watch 451 continues. SUMMARY...An isolated strong to severe wind threat persists. The need for a downstream watch remains unclear, but an extension in area to WW 451 has been made to address the short-term severe threat. DISCUSSION...A small MCS now moving across west-central into southwestern OK has produced mainly sub-severe wind gusts up to around 50 mph over the past hour or so based on Mesonet and ASOS/AWOS observations. Nearly all high-resolution guidance available indicates this cluster will slowly weaken over the next couple of hours as a southerly low-level jet diminishes. Observations have yet to show this weakening trend, and up to 1000 J/kg of MUCAPE and sufficient deep-layer shear may still support some threat for convective organization with the cluster for the next hour or two. If the MCS can maintain its intensity, then an isolated threat for strong to severe wind gusts would continue into more of southwestern OK and perhaps parts of western north TX. The need for a downstream watch remains unclear given the eventual weakening trend anticipated. But, a local extension in area to Severe Thunderstorm Watch 451 has been made to address the continued short-term severe threat. ...Gleason/Bunting.. 07/06/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!5km4kxc2tuLzQVadDwjEHNTBAvoc6LKwIDDQM5W5yDzRPUkm5mb69U0GsgAP9Nxnul1889eP9= ZLma6fdyaImcFa2iJU$ for graphic product...
