Valid 100149Z - 100245Z The severe weather threat for Severe Thunderstorm Watch 679 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 679. Large hail is the main threat with the stronger storms. DISCUSSION...Multiple supercell thunderstorms are persisting across eastern WY, with MRMS MESH indicating severe hail occurring with multiple storms (perhaps exceeding 2 inches in diameter with the storm in northern Platte County). Though boundary-layer decoupling is in progress, strong vertical shear, steep mid-level lapse rates, and associated residual CAPE atop the boundary layer will support a continued severe hail threat for at least a few more hours. ...Squitieri.. 09/10/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!-1536lhoSiV8MNtXluwREVxM1UMOO7k-fHwxl7PV4XsGcsHjFXxfOABuTI_lLrzmzSGXKNWjJ= u9vFvLb-Mdj3Zrhi3k$ for graphic product...
