The severe weather threat for Severe Thunderstorm Watch 174
SUMMARY...Storms forming north of the supercell in Clark County, KS
should congeal into one or two supercells this evening. These storms
will pose a risk for large hail and damaging winds, but are expected
to wane after dark which will likely preclude the need for a severe
thunderstorm watch north of watch 174.
DISCUSSION...In addition to the persistent supercell along the
Oklahoma/Kansas border and a cluster of supercells northeast of
Amarillo, storms are starting to form further north along the
stationary front in Kansas. Given the very unstable environment and
effective shear around 35 to 40 knots, expect the developing cells
in Kansas to organize into one or two dominant supercells with large
hail and damaging winds as the primary risk. This new development
will likely wane shortly after sunset with the better organization
relegated to areas further south within WW 174 where storms are more
likely to congeal and the threat may persist into the early
overnight hours. Given the short duration of the threat, a severe
thunderstorm watch is not expected for areas north of Severe
Thunderstorm Watch 174.
