Concerning...Severe Thunderstorm Watch 297...
Valid 312253Z - 010030Z
The severe weather threat for Severe Thunderstorm Watch 297
continues.
SUMMARY...Scattered strong/severe thunderstorms will persist across
ww297 this evening.
DISCUSSION...In the absence of any appreciable mid-level short-wave
trough, it appears frontal convergence and weak low-level warm
advection atop the boundary will be the primary forcing mechanisms
for convection this evening. While surface heating proved
instrumental in thunderstorm development across ww297 late this
afternoon, southerly 850mb flow is expected to increase across the
TX South Plains into northern OK later this evening. This should
contribute to some southward propagation, although the primary storm
motion will remain easterly around 20kt. Most robust updrafts are
producing severe hail and this is expected to continue for at least
the next several hours. With time, thunderstorms may spread/develop
across southeast/east-central KS along the nearly stationary
boundary that is draped across this region.
