   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
   THE SOUTHERN AND CENTRAL PLAINS INTO THE LOWER TO MID MISSOURI
   VALLEY...

   ...SUMMARY...
   Isolated severe thunderstorms, with a primary threat of large hail,
   are possible this evening into tonight from parts of the southern
   and central Plains into the lower to mid Missouri Valley.

   ...Southern and Central Plains/Lower to Mid Missouri Valley...
   A mid-level ridge will move eastward across the Great Plains today,
   as a surface low develops across northern Nebraska. In the wake of
   the ridge, moisture advection will increase across the southern and
   central Plains from late afternoon into the evening. By
   00Z/Thursday, a moist axis will be located from central Oklahoma
   into central Kansas where surface dewpoints are forecast to be
   mostly in the 50s F. Early this evening, a 40 to 50 knot low-level
   jet is forecast to rapidly develop from western Oklahoma into
   west-central Kansas. Lift associated with the jet and low-level
   convergence near the dryline may be enough for isolated convective
   initiation. If storms can initiate and grow upscale, then isolated
   large hail and marginally severe gusts will be possible, aided by
   steep 700-500 mb lapse rates. During the mid to late evening, the
   potential for isolated thunderstorms capable of producing hail will
   likely develop eastward across parts of east-central Kansas and
   southeast Nebraska. As warm advection increases overnight, the hail
   threat may eventually affect parts of western Missouri and southwest
   Nebraska.
