Mesoscale Discussion 1507 NWS Storm Prediction Center Norman OK 0928 PM CDT Sat Aug 15 2020 Areas affected...Northern Oklahoma Concerning...Severe Thunderstorm Watch 442... Valid 160228Z - 160400Z The severe weather threat for Severe Thunderstorm Watch 442 continues. SUMMARY...Isolated strong/severe thunderstorms will move west across northern Oklahoma over the next few hours. Some hail and wind remain possible. DISCUSSION...Small cluster of thunderstorms that developed over southwest MO earlier this afternoon have propagated west-southwest over the last few hours, and continue at roughly 20 kt. Despite the lack of large-scale forcing, these updrafts have largely continued due to moisture/strong buoyancy observed across northern OK. However, over the last hour or so it appears updraft intensity has weakened considerably. Given these trends, marginally severe hail and winds generally less than 50 mph may be noted with this small cluster as it spreads toward the western edge of ww442 by 04z. ..Darrow.. 08/16/2020 ...Please see www.spc.noaa.gov for graphic product...
