Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Jun 30, 3:29 PM CDT, 1 hour 7 minutes before

Area Forecast Discussion
National Weather Service Hastings NE
329 PM CDT Sat Jun 30 2018

.SHORT TERM...(This evening through Sunday)
Issued at 328 PM CDT Sat Jun 30 2018

A few thunderstorms have developed along a front that is nearly
stationary across far southern Nebraska this afternoon. Otherwise,
there are mostly cloudy skies for much of the area. Temperatures to
the south of the front are in the upper 80s to lower 90s and to the
north are mostly in the upper 70s and 80s.

The initial period will be the most interesting. The front should be
the focus of thunderstorms during the late afternoon hours. This
area has dew points around 70 degrees. These will be mainly wind and
hail as they affect the area this afternoon into the evening. Later,
mainly during the evening hours, an upper level wave will move into
the area and bring a line of thunderstorms into the area. These
should develop on the high plains and move into the area during the
evening. These storms will have mainly wind as the storms move
through. All of the storms should be through the forecast area by
morning.

A surface high moves into the area behind the thunderstorms and
clears things out for Sunday. The skies will become sunny, but
temperatures will be a little cooler with highs only in the 80s.
This will be cooler than much of the last week has been.

.LONG TERM...(Sunday night through Saturday)
Issued at 328 PM CDT Sat Jun 30 2018

Sunday night through Monday should be a dry period, with
temperatures warming up a little. The surface high moves to the east
Sunday night and by Monday the winds turn to the south and will help
temperatures warm a little.

The south winds will continue to bring in warmer temperatures
through Tuesday. There is a weak upper level wave that moves through
the area Monday night and there could be a few thunderstorms.

For the period Tuesday night through Saturday there will be an upper
level ridge across the central and eastern part of the CONUS. There
are a few mainly weak upper level waves that move around the ridge.
There could be a few thunderstorms, but they should be more on and
off and not very widespread. Temperatures will be fairly warm with
highs in the upper 80s and 90s across the area.

&&

.AVIATION...(For the 18Z KGRI/KEAR TAFS through 18Z Sunday)
Issued at 1224 PM CDT Sat Jun 30 2018

The MVFR ceilings should be relatively short lived and there could
be a little clearing during the afternoon, just enough to get more
thunderstorm development for later this afternoon and into the
evening. The thunderstorms should move out of the area late
tonight and clearing is expected behind the thunderstorms as a
surface high builds into the area.
