Areas affected...Central Plains

Concerning...Severe Thunderstorm Watch 539...

Valid 232333Z - 240130Z

The severe weather threat for Severe Thunderstorm Watch 539
continues.

SUMMARY...Strong-severe thunderstorms will advance steadily east
this evening.

DISCUSSION...Slow-moving upper disturbance that drifted across
northeast CO appears to be aiding a considerable amount of
convection, along/behind a surface front that is draped across the
central Plains early this evening. Over the last few hours,
thunderstorms have gradually increased in areal coverage along/near
the frontal zone, extending from northwest KS into northern NE. An
elongated, frontal MCS appears to be evolving, and this activity
should propagate downstream as the synoptic boundary sags southeast
this evening. Some increase in the LLJ will likely assist this
propagation. Hail is the primary risk, along with some threat for
wind.
