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.

some storms capable of producing large hail and damaging wind.
Storms are expected to undergo a weakening trend as they move east

remain northwest of I-44. Locally heavy rainfall can be expected,
especially locations northwest of Interstate 44 and likely will
result localized, quick-onset flash flooding.

EXTENDED DISCUSSION...

northeast Oklahoma, but overall storm coverage looks to be lower.

this system will have the potential for significant severe
weather and flooding threat.
