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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Amarillo, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 28, 6:09 PM CDT, 1 hour 28 minutes earlier.

Area forecast discussion, Jun 28, 6:09 PM CDT, 1 hour 28 minutes before

Area Forecast Discussion
National Weather Service Amarillo TX
609 PM CDT TUE JUN 28 2016

.Aviation...
00Z TAF Cycle

An upper ridge will prevail across the three TAF sites through 00Z
Thursday. Isolated convection could possibly affect the Dalhart TAF
site later tonight between about 10Z to 14Z Wednesday and should not
affect the Amarillo or Guymon TAF sites. VFR conditions will prevail
with mainly southeast to south winds 5 to 15 knots or less.

.Prev Discussion... /Issued 433 PM CDT TUE JUN 28 2016/

Discussion...
No big changes to the previous grids and forecast this forecast
package. An upper ridge will continue to build east in over the
Panhandles by Thursday and Friday. Isolated convection this afternoon
mainly across the northern and eastern Panhandles should dissipate by
late this evening with additional convection tracking southeast
across the northern and eastern Panhandles again by Wednesday
afternoon and evening. A frontal boundary stretching across southwest
Kansas will remain quasi-stationary through Wednesday will push
south into the forecast area during the latter half of the week and
into the weekend. Chances for convection will increase by late this
week and this weekend as the front pushes into the Panhandles. A few
storms could become strong to marginally severe with strong and gusty
winds along with locally heavy rainfall being the primary threats.
