Areas affected...portions of central and eastern Nebraska

Concerning...Severe Thunderstorm Watch 592...594...

Valid 180421Z - 180545Z

The severe weather threat for Severe Thunderstorm Watch 592, 594
continues.

SUMMARY...A brief bout of severe hail or a gust may still occur with
one of the stronger embedded cells within the broader thunderstorm
cluster. However, the overall severe threat should diminish with
time tonight.

DISCUSSION...A loosely organized MCS continues to propagate eastward
as cold pools with surrounding supercells and multicells merge. 04Z mesoanalysis depicts increasing MLCINH, indicating a gradually
decoupling boundary layer. Ongoing storms should continue to become progressively elevated with time, which will further limit the
severe threat. In the next 1-2 hours though, isolated severe hail or
wind may accompany the stronger storm cores given over 2000 J/kg
MUCAPE and 40+ kts of effective bulk shear in place.
