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 flash flood 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
Norman, OK (KOUN), launched 00:00Z, 1.4 hours before the alert went out and 231 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 National Weather Service Tulsa OK 712 PM CDT Thu May 28 2026 ...New AVIATION... .KEY MESSAGES... Updated at 655 PM CDT Thu May 28 2026 - Medium to high (40-80%) precipitation chances will continue through tonight across far northwest Arkansas, with lessening chances elsewhere by this evening and overnight. Locally heavy rainfall, minor flooding, and isolated flash flooding will be possible, especially in far northwest Arkansas. - Daily rain and storm chances continue through the weekend and into next week. Locally heavy rainfall will remain the primary concern, which could lead to isolated flash flooding. A limited severe weather threat will also occur. - Temperatures warming to above normal over the next several days. && .SHORT TERM... (Through tonight ) Issued at 1139 AM CDT Thu May 28 2026 Low level circulation just north of Tulsa will continue to lift north this afternoon and tonight. Showers and isolated thunderstorms will continue to develop and rotate around this circulation, with the greatest coverage of showers and storms expected across far northwest Arkansas by this evening and overnight. Locally heavy rainfall may occur, especially in far northwest Arkansas, which may lead to some localized flooding concerns, especially in parts of Carroll county Arkansas. && .LONG TERM... (Tomorrow through Thursday) Issued at 1139 AM CDT Thu May 28 2026 Precipitation coverage will be much lower, but non zero, in the coming days. With added sunshine, temperatures will also be on the rise, with most locations warming into the upper 80s to near 90 by the weekend. While shower and thunderstorm coverage will be less, instability will be greater, so a conditional risk for severe storms will exist Friday through the weekend, despite marginal wind profiles. The greatest severe weather threat may be late Saturday afternoon and especially Saturday evening as an upper level storm system passes to our north. Locally heavy rainfall will be possible with any storms that do occur. Heading into next week, not much change is expected, with daily low shower and thunderstorm chances. Slow moving storms will continue to result in a locally heavy rainfall potential and a very limited severe weather threat. && .AVIATION... (00Z TAFS) Issued at 712 PM CDT Thu May 28 2026 VFR conditions will prevail outside of showers and storms before coverage drops aft 01Z or 02Z. Guidance has low clouds overspreading most of the TAF sites overnight toward Friday morning, with cigs expected to ultimately drop to IFR levels. Latest short-term models develop spotty showers and storms by Friday morning across NE OK, with activity increasing in coverage and spreading east and south into NW AR and SE OK later in the day. Used prob30 groups to cover the potential for now. Cigs should rebound back to VFR by Friday afternoon. Lacy && .PRELIMINARY POINT TEMPS/POPS...
