Mesoscale Discussion 1660 NWS Storm Prediction Center Norman OK 0837 PM CDT Mon Aug 31 2020 Areas affected...Northwest TX to Southeast KS Concerning...Severe Thunderstorm Watch 480... Valid 010137Z - 010300Z The severe weather threat for Severe Thunderstorm Watch 480 continues. SUMMARY...Isolated large hail and damaging wind threat continues. DISCUSSION...Southern High Plains short-wave trough continues its slow eastward progression into western OK/northwest TX. Surface front that settled into this region has moved little over the last few hours and there does not appear to be an adequate cold pool to significantly shunt this boundary appreciably south over the next few hours. Weak low-level warm advection will continue along the frontal corridor which should provide some assistance for renewed convection. Radar data confirms this scenario with new updrafts evolving southwest-northwest of the OKC metro. Hail remains possible with the younger-mature updrafts, then gusty winds will be the primary threat. Otherwise, very heavy rainfall remains likely with these storms. ..Darrow.. 09/01/2020 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...TSA...ICT...OUN...LUB...
