Using SPC Meso-analysis reveals favorable environment for storm development. CAPES in the 1500-2000 J/kg range.Over the GLD CWA and surrounding counties expect storms in southern Nebraska to move southeast into the forecast area, most likely along the outflow boundary that was approaching from eastern Kansas and from the isolated thunderstorms just developing in eastern Colorado.  Looked at the RGB in which the color curve highlights the lower level clouds in southeast Kansas to southern Missouri(magenta in lower right image). Too much cloud development by this time for 10.33-12.33 to show any moisture convergence not already seen in the visible.
