The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

The nearest sounding before it

N. Platte/Lee Bi, NE (KLBF), launched 12:00Z, 11.4 hours before the alert went out and 68 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jun 10, 2:33 PM MDT, 2 hours 53 minutes before

Area Forecast Discussion
National Weather Service North Platte NE
333 PM CDT FRI JUN 10 2016

.SYNOPSIS...
Issued at 327 PM CDT Fri Jun 10 2016

Closed low over the Pacific Northwest Hudson Bay and Greenland
with jet stream well north. There is a ridge over the desert
southwest into the northern plains with upper trough from Iowa
into the Texas panhandle.

&&

.SHORT TERM...(This evening through Saturday)
Issued at 327 PM CDT Fri Jun 10 2016

Tonight...Main concern is a week frontal boundary that continues to
slowly sag southeast from northwest Nebraska extending back across
southwest Nebraska. This may generate a few isolated showers and
thunderstorms as it pushes through...have added isolated pops this
evening. However none of these storms are expected to be severe.

Tomorrow...Heat will be the major concern for the short term...a
heat advisory has been issued for parts of north central Nebraska
where highs will be in the upper 90s and heat indices will be around
100. Heat advisory will be in effect from 18z until 02z Saturday
evening. Areas across the rest of the Sandhills will still see highs
in the 90s but at this time do not warrant a heat advisory.

.LONG TERM...(Saturday night through Friday)
Issued at 327 PM CDT Fri Jun 10 2016

Models in fair agreement in the near and long term. Strong upper
low over the Pacific northwest and the ridge through the northern
plains will continue to be main forecast challenges through the
mid and extended forecast. Saturday night will continue very warm
with lows around 70 over most of the forecast area. Heat advisory
continuing into the early evening over north central Nebraska from
Valentine to Oneill. Very slow recovery on temperatures and dew
points in the mid to upper 60s. Strong cap to continue with 15C to
16C at 700mb. Front timing issues will keep Sunday time frame
somewhat in question. Have delayed precipitation over western
Nebraska until Sunday afternoon and have gone with cooler
temperatures to the northwest for highs on Sunday only in the 80s
over northwest with 90s ahead of the front. Day3 has western
Nebraska in Marginal. With strong temperature gradient and
strength of front may have to be upgraded. Front passing through
Sunday night with best forcing and a half inch QPF. Upper wave
moves out of 4 corners through the first part of the work week and
closes off over western Nebraska Tuesday afternoon and Wednesday.
Upper ridge building back in Wednesday through Friday with highs
near normal in the 80s and dry.

&&

.AVIATION...(For the 12Z TAFS through 12Z Saturday morning)
Issued at 659 AM CDT Fri Jun 10 2016

Vfr conditions the next 24 hrs at the klbf and kvtn terminals.
there will be a weak frontal boundary between oga and anw which
will help to focus isolated thunderstorms. any storm which do
develop should remain outside the klbf and kvtn vicinity.

&&

.HYDROLOGY...
Issued at 327 PM CDT Fri Jun 10 2016

Moderate flooding will continue along the North Platte River at
North Platte and the North Platte River at Lewellen. River levels
will remain elevated along the South Platte River at Roscoe and
North Platte. Elevated river levels also continue along the Platte
River at Brady and the North Platte River at Lisco.
