Concerning...Severe Thunderstorm Watch 172...173...
Valid 120232Z - 120430Z
The severe weather threat for Severe Thunderstorm Watch 172, 173
continues.
SUMMARY...A threat of damaging wind and hail continues across the
watch area, and may extend into the remainder of southeast Kansas
and western Missouri this evening.
DISCUSSION...An MCS stretches from northeast KS into south central
IA as of 0230Z. Northern portions of the line previously contained
measured severe winds, but, may begin to weaken a bit as the most
unstable air remains to the southwest. The bulk of the MCS was
beginning to propagate in a more southerly direction, with locally
damaging outflow winds along with embedded hail cores. A very
unstable air mass extends from OK across eastern KS, and this air
mass should maintain the MCS as it travels across the severe
thunderstorm watch. Another watch may be needed later this evening
for portions of southeast KS and western MO, should the storms still
be severe at that time.
Farther north into central IA, the threat appears more marginal for
both wind and hail, with a gradual weakening trend expected as these
storms encounter a stabilizing air mass due to cool east winds.
