The National Weather Service in Tulsa issued a Severe Thunderstorm Warning for northeastern Osage County, Oklahoma early Sunday morning, as a radar-confirmed storm carrying 60 mph wind gusts and penny-size hail pushed east through the region.
At 6:52 a.m. CDT, the storm was located over Pearsonia, moving east at 30 mph. The warning remains in effect until 7:30 a.m. CDT.
Hazards
The National Weather Service flagged two primary threats: wind gusts of 60 mph and penny-size hail. The agency warned specifically of damage to roofs, siding, and trees — typical outcomes when gusts reach that level in a summertime convective event.
The warning is radar-indicated, meaning forecasters at NWS Tulsa detected the storm’s intensity via radar rather than from a ground-spotter report. That is a routine procedure during early-morning warnings when spotter networks have limited visibility across rural terrain.
Who Is Affected
The warning covers northeastern Osage County, a largely rural section of northeastern Oklahoma. With the storm tracking east at 30 mph, conditions can deteriorate rapidly for communities directly in its path. The warning window — from the time of detection at 6:52 a.m. through expiration at 7:30 a.m. CDT — spans less than 40 minutes, but the storm’s approach can bring severe weather with very little lead time.
The National Weather Service advises anyone in the warned area to move immediately to an interior room on the lowest floor of a building. Those caught outside or in a vehicle should seek substantial shelter before the storm arrives. Avoid windows.
What Comes Next
NWS Tulsa is monitoring the storm’s eastward progression for signs of additional development or intensification. While the current warning is confined to northeastern Osage County, communities along the storm’s eastward track should remain alert to any new advisories as the cell continues to move through.
Residents near Tulsa weather and across northeastern Oklahoma should keep a close eye on local radar through the morning hours. Severe weather situations in this region can shift quickly, and the National Weather Service may issue updated or expanded warnings as the storm evolves.
Alerts are available through NOAA Weather Radio and local emergency broadcast systems. The National Weather Service will cancel or update the warning as conditions warrant.
