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 National Weather Service Las Vegas NV 124 AM PDT Fri Aug 14 2026 .KEY MESSAGES... * Limited shower activity lasts through much of the morning with another batch of isolated to scattered thunderstorms expected this afternoon. Storm chances reduce into the evening, then exit by the late night. FLash Flood Watches are in affect for Northern Mohave County and most of Lincoln County. * Mostly dry conditions are expected over the weekend and into the next work week. * The weekend starts off another steady warming trend. && .DISCUSSION...We're continuing to see very light returns on the radar around the southern portions of the CWA, while Lincoln Co still has some passing storms that will weaken into the late night. Non-impactful shower activity looks to linger through the morning, with better chances for convection arriving into the afternoon. Northern Mohave County AZ will see the better chances for storms as the monsoonal flow will be slightly more focused on that side of the state line. Storm chances do look to spread west into the mid afternoon offering more widespread storm chances. Even though the moisture feed will be limited compared to previous days, localized flooding will still be a concern along with strong gusts. lightning, and maybe some hail. Shorter-term higher resolution models are showing a possible conveyer belt of storms moving through northern Mohave Co AZ in the early afternoon and again in the early evening. Portions of Lincoln Co will also have the potential for training storms. As such, a Flash Flood watch remains in effect for northern Mohave County and most of Lincoln County through 8 PM this evening. The upper level pattern will shift into Friday night with a ridge of high pressure tilting into the region. This will inhibit storm chances over the weekend, with the exception of some slight chances for isolated storms on some of the higher peaks. The high pressure will continue to build into the work week, keeping the forecast dry. Longer term models hint at the high pressure beginning to push east by the next weekend, but that could be delayed further beyond the forecast period. The building high pressure will also kick off a warm trend over the weekend with temperatures slowly rising back into the 100s and 110s by the middle of the next work week. && .AVIATION...For Harry Reid...For the 12Z Forecast Package...Light, variable winds will continue through mid-morning before light easterly winds (080 to 120 degrees true) develop by midday. Another round of convection is expected across southern Nevada by early afternoon. The best chance for direct impacts in the terminal area will be 20Z to 01Z, with the likely impacts being sudden gusty winds, heavy rainfall reducing visibility to under 5SM, and CIGs decreasing to below 8kft AGL. There is also a 30 percent chance that scattered convection will persist into the evening before ending. Light and variable winds will return overnight. Away from areas of convection, VFR conditions will prevail with SCT to BKN clouds and bases remaining AOA 10kft AGL. Temperatures are expected to remain below 100F once again today and remain below 100F through the weekend. For the rest of southern Nevada, northwest Arizona and southeast California...For the 12Z Forecast Package...Thunderstorms are expected to redevelop this afternoon across southern Nevada and northern Mohave County. Any storms could produce sudden gusty winds, lightning, heavy rain reducing visibilities to below 5SM, and CIGs decreasing to below 8kft AGL. While convection will be more limited across southern portions of the region today, an isolated storm cannot be ruled out, especially in the lower Colorado River Valley during the late afternoon and early evening. Away from convective influences, south to southwest winds of 10 to 15 knots with gusts to around 20 knots will develop. Conditions will improve across the region overnight, with both convection and winds diminishing. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Murdock AVIATION...Planz For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
