Areas affected...central Nebraska

Concerning...Severe Thunderstorm Watch 579...

Valid 130350Z - 130545Z

The severe weather threat for Severe Thunderstorm Watch 579
continues.

SUMMARY...Severe potential continues within WW579.

DISCUSSION...A slow moving cluster of thunderstorms continues to
evolve eastward along north/south combining outflow boundaries.
Occasional gusts of 50-60 mph have been reported. Ahead of the
ongoing convection, a precipitation shield has developed. Nocturnal
cooling and increasing MLCIN are noted ahead of the line across
central Nebraska. Nonetheless, 00z observed sounding from OAX would
suggest that appreciable MUCAPE is available downstream. VAD
profiles across Oklahoma and Kansas are starting to sample the
increasing 30-35 kt southerly low-level jet (LLJ). This is forecast
to further increase and nudge into portions of southern Nebraska
over the next couple of hours. Hi-res and ensemble guidance continue
to suggest that some increase in intensity of convection will be
possible as this occurs, with potential for damaging wind to
continue across central Nebraska after 06z.
