Areas affected...portions of northwestern Kansas into central
Nebraska
Concerning...Severe Thunderstorm Watch 612...
Valid 170144Z - 170315Z
The severe weather threat for Severe Thunderstorm Watch 612
continues.
SUMMARY...Some severe threat will persist for a few more hours, with
severe gusts/hail the main threats.
DISCUSSION...Currently, two general areas of convection continue to
show severe potential. Firstly, a line of thunderstorms has quickly
intensified across extreme northwestern KS, along the NE border, in
association with several cold pool and convective outflow boundary
mergers. These storms will continue to propagate east-southeastward
amid a buoyant airmass characterized by 1500 J/kg MLCAPE. In central
NE, an embedded bowing structure has produced some measured 50+ kt
gusts, and this potential may continue for the next hour or so as
well. However, waning buoyancy and increasing MLCINH amid
boundary-layer decoupling should gradually reduce severe potential
over the next few hours.
