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.
