Mesoscale Discussion 1884 NWS Storm Prediction Center Norman OK 0747 PM CDT Sun Aug 11 2024 Areas affected...West-central Nebraska...Northwest Kansas Concerning...Severe Thunderstorm Watch 619... Valid 120047Z - 120245Z The severe weather threat for Severe Thunderstorm Watch 619 continues. SUMMARY...A threat for isolated large hail and severe wind gusts will likely continue for an hour or two, before becoming marginal. No additional weather watch issuance is expected. DISCUSSION...Mosaic radar imagery shows scattered to widely scattered strong to severe storms located from north-central Nebraska into far northwest Kansas. The storms are located to the east of an axis of moderate instability, where the RAP has MLCAPE in the 1000 to 2000 J/kg range. This, combined with moderate deep-layer shear, evident on regional WSR-88D VWPs, will continue to be favorable for severe storms over the next couple of hours. Severe wind gusts and isolated large hail will be the primary threats. However, the storms will move eastward into the central Plains, where instability is weaker and a capping inversion is present. This will result in a gradual weakening trend during the mid to late evening. ..Broyles.. 08/12/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...GID...LBF...DDC...GLD...
