The radar

The Tulsa radar (KINX), 90 km from the middle of the area, began a volume at 08:14 UTC, the scan nearest the moment this went out.

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 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 nearest sounding before it

Norman, OK (KOUN), launched 00:00Z, 8.3 hours before the alert went out and 208 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.

National Weather Service Tulsa OK
1202 AM CDT WED OCT 12 2016

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Scattered showers and thunderstorms will remain possible overnight
across parts of Northeast Oklahoma into far Northwest Arkansas as
a cold front approaches. Also overnight into Wednesday...southerly
winds could help to transport areas of MVFR ceilings into
Southeast Oklahoma and Northwest Arkansas. During the day
Wednesday...showers and thunderstorms will continue to be possible
mainly over Northeast Oklahoma into Northwest Arkansas ahead of
the front...with scattered rain chances behind the front into
Wednesday evening. The front is forecast to move into Northeast
Oklahoma mid morning Wednesday and exit Southeast Oklahoma and
Northwest Arkansas toward the end of the TAF period. Behind the
front...breezy northerly winds and IFR/MVFR ceilings look to be
possible.

.PREV DISCUSSION... /Issued 835 PM CDT TUE OCT 11 2016/

..UPDATE...

DISCUSSION...
A few showers/thunderstorms have developed across northwest
OK...east of the dryline and south of the approaching cold
front in a ribbon of higher dewpoint air. Recent runs of the
HRRR eventually shift this activity east toward northeast OK
later this evening...with some increase in coverage overnight
as the cold front nears.

Overnight forecast is in reasonable shape...although introduced
some low PoPs the remainder of the evening for the far northwest
portions of the forecast area.
