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 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 Elko, NV wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 26, 3:04 PM PDT, 4 hours 11 minutes earlier.
Area forecast discussion, Jul 26, 3:04 PM PDT, 4 hours 11 minutes before
Area Forecast Discussion National Weather Service Elko NV 304 PM PDT Wed Jul 26 2017 .SYNOPSIS...Showers and thunderstorms will persist into the evening. Brief moderate to heavy rain is possible in the storms, along with hail and gusty outflow winds. Afternoon thunderstorm activity lingers over portions of the region later this week, however activity will be slightly less. && .SHORT TERM...Tonight through Friday. Showers and thunderstorms have started a little earlier than yesterday. Storms are tracking a little faster today which will lead to a lessened flood threat. The activity will continue into the evening hours. Main threats continue to be wind gusts to 60 mph along with brief moderate to heavy rain and small hail. For tomorrow, moisture levels will decrease slightly, helping to limit convective activity. Still, have kept mainly isolated showers and thunderstorms across the area. Highs will be in the 90s. Thursday night and Friday. The slight drying trend continues, but still cannot rule out isolated storms for the afternoon. Highs will be in the 90s. .LONG TERM...Friday night through next Wednesday. Upper ridge will gradually rebuild over the Great Basin this weekend into next week. Moisture and weak instability will remain under this feature which will keep the threat of thunderstorms developing each day across portions of central and eastern Nevada. Extent of moisture would support scattered storms through the heart of the CWA on Saturday, some of which might be capable of producing locally heavy rainfall and flash flooding. Available moisture and subsequent storm coverage is trending to be more isolated through the middle of next week. Temperatures will continue above normal with daytime highs in the 90s and lows at night in the mid 50s to mid 60s. && .AVIATION...Given available moisture and instability, scattered showers and thunderstorms will redevelop once again this Wednesday afternoon around and en route of all TAF sites. Scattered storms will persist through mid- evening before diminishing to light rain showers and finally dissipating overnight. Outflow winds over 35 knots, locally heavy downpours, and small hail along with reduced visibilities to below MVFR are likely in the vicinity of stronger convective cells. There is also an increased risk today of isolated severe gusts/wet microbursts to 50 knots associated with a few of the more intense descending storm cores per SPC Day 1 convective outlook/discussion that has northern and central Nevada in the heart of a marginal area for severe weather. && .FIRE WEATHER...The scattered showers and thunderstorms will continue to affect the area this evening. Some slight drying will take place tomorrow with fewer storms possible, mainly in the isolated category. These will be located in the eastern counties of Elko and White Pine counties. && .LKN WATCHES/WARNINGS/ADVISORIES... None. && 86/95/95/86
