Valid 040823Z - 041000Z The severe weather threat for Severe Thunderstorm Watch 453 continues. SUMMARY...Localized severe gusts and isolated hail remain possible through the early morning. DISCUSSION...Earlier intense supercells have evolved into a small bowing segment across far northeast CO as of 0815 UTC. This small cluster has a history of producing observed severe gusts, and may continue to pose a severe-wind and isolated hail threat as it moves into far northwest KS. Extensive downstream convection near and southeast of Goodland may eventually limit the longevity and eastern extent of the severe threat of this cluster. The strongest storms within the warm-advection regime may also pose a threat for isolated hail and localized strong to severe gusts, given the presence of moderate elevated buoyancy and sufficient effective shear. ..Dean.. 07/04/2026 ...Please see www.spc.noaa.gov for graphic product...
