   Areas affected...I-70 corridor from northern Kansas into northwest
   Missouri

   Concerning...Severe Thunderstorm Watch 154...

   Valid 270639Z - 270815Z

   The severe weather threat for Severe Thunderstorm Watch 154
   continues.

   SUMMARY...Elevated supercells will continue to pose a large hail and
   isolated damaging wind threat while spreading eastward along the
   I-70 corridor.

   DISCUSSION...Clusters of elevated supercells, with a recent history
   of hail up to 2 inches in diameter, continue to spread eastward
   along the I-70 corridor in north central and northeast KS.  This
   area is within the left-exit region of a 100 kt jet at 300 mb, and
   along the north edge of the steep midlevel lapse rates where strong
   low-level warm advection is ongoing.  The updrafts appear to be
   rooted near 850 mb with MUCAPE near 3000 J/kg.  The combination of
   large buoyancy and strong cloud-layer/effective shear will continue
   to favor supercells capable of producing very large hail (near or
   above 2 inches in diameter).  These storms will also be capable of
   producing isolated wind damage given the steep midlevel lapse rates
   and moderately large DCAPE.
