Mesoscale Discussion 2015 NWS Storm Prediction Center Norman OK 0246 PM CDT Tue Aug 27 2024 Areas affected...central into eastern Lower Michigan Concerning...Severe Thunderstorm Watch 656... Valid 271946Z - 272145Z The severe weather threat for Severe Thunderstorm Watch 656 continues. SUMMARY...Storms over central Lower Michigan continue to pose a strong to severe wind threat, with gusty wind potential spreading east over the next several hours. DISCUSSION...Storms with extensive outflow have pushed across Lake MI and into western MI, producing locally severe gusts. Although current radar presentation shows rather broken cell structures, fast-moving outflow continues to push east. Given the strongly unstable air mass developing ahead of the outflow, some severe potential will likely spread eastward through the afternoon, with strong to locally severe gusts. Shear remains weak but new development is possible along the outflow with some degree of forward propagation expected. Also aided downdraft potential are precipitable water values in excess of 1.75" and steepening low-level lapse rates into the peak heating hours. ..Jewell/Guyer.. 08/27/2024 ...Please see www.spc.noaa.gov for graphic product...
