New watch issuance will be issued soon. DISCUSSION...The cap has been breached across south-central KS, with explosive development recently noted with a supercell in south-central KS. An extremely unstable airmass is present in a narrow corridor along/west of outflow from prior convection across southeastern KS. With 4000-5000 J/kg of MLCAPE and 50+ kt of deep-layer shear, any supercell which can be sustained will pose a threat for very large hail of 2-3+ inches in diameter along with severe/damaging outflow winds. Although the number of supercells which will develop remains uncertain, the very favorable thermodynamic and kinematic environment, along with ongoing intense convective development, will require new Severe Thunderstorm Watch issuance soon. ...Gleason/Bunting.. 07/17/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!_dSW1KnzD12w2LP4slSOw8dQLs4rlRH4hPTuw3P4U7rdxbcr5TC5FBZ5ZMsza0TiQIbsQHAOV= vdgH4zsJ6LFWq2SNDs$ for graphic product...
