Watch likely. DISCUSSION...Visible satellite shows a northward advancing area of developing cumulus, associated with low-level moisture advection, over southern/southeastern Kansas into far west-central Missouri, beneath a broken layer of northeastward streaming mid-level cloud cover. Some vertical development in the low-level clouds can be noted along the stalled frontal boundary oriented from northwest Oklahoma/Texas Panhandle into northeast Kansas, particularly near an analyzed meso-low over central Kansas, and along the edge of a modified cold pool from an overnight/morning MCS, stretching from west-central to far southern Missouri. Surface temperatures have warmed into the upper 80s F within the warm sector, where dew point temperatures are in the low to mid 70s F. Consequently, the atmosphere is undergoing rapid destabilization, where MLCAPE values are now exceeding 3000 J/kg. As the area continues to destabilize, widespread convective development is anticipated over the region within the next few hours, particularly along the aforementioned baroclinic zones initially. Effective bulk shear of 35-40 kt is common across the region (lessening with southward extent), and should help to organize the convection into multicellular/supercellular structures capable of large hail and damaging wind gusts. Watch issuance can be expected soon. ..Karstens/Hart.. 06/22/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...EAX...TSA...OAX...TOP...ICT...OUN...GID... DDC...AMA...
