Tornadoes, large hail, and severe wind gusts are expected with a midday tornado watch issuance. DISCUSSION...15Z surface analysis placed the composite cold front/dryline across southwest NE into far western KS. A lobe of large-scale ascent indicated by a patch of upper-level cirrus along the KS/CO border will rapidly spread northeast and likely aid in convective development along the KS/NE border area during the next few hours. A plume of at least moderate buoyancy is already present, with earlier MLCIN noted in 12Z LBF/DDC soundings waning. Enlarged/elongated hodographs will favor supercell structures, especially with southern extent where a couple strong tornadoes will be possible. Linear frontal forcing and potential for pinching of the northeast portion of the surface-based buoyancy plume should yield greater potential for upscale growth earlier with northern extent. A mix of tornadoes, large hail, and severe wind gusts is expected. ...Grams/Smith.. 05/06/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!96kbYMb2BeXZ7dsLoWiPjoMLoDzCPGPW9wdXPUQ2OdmUXPXA185_94WcyqiM2DRzMmb0wyaji= fztXtOoh75szrGsqtg$ for graphic product...
