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 TULSA OK
357 AM CDT SAT APR 14 2012

.DISCUSSION...
TORNADO WATCH THIS MORNING FOR NORTHEAST OKLAHOMA. STRONG TO
SEVERE CELLS MOVING INTO NORTHEAST OKLAHOMA...WITH OCCASIONAL
CIRCULATIONS EVIDENT. WILL CARRY HIGH LATE NIGHT POPS WITH THE
WEATHER BUT LOWER POPS LATER IN THE DAY AS DIURNAL CYCLE SHOULD
PERMIT CONVECTION TO WEAKEN. MODELS ALSO INDICATE THIS. A CHANCE
OF STORMS DURING THE AFTERNOON...MAINLY NORTH...THE MAIN EVENT
WILL OCCUR TONIGHT. EXPECT FIRST ACTIVITY TO ENTER OSAGE AND
PAWNEE COUNTIES...AND WORK TO THE SOUTHEAST THROUGH THE NIGHT.
SEVERE STORMS LIKELY SOMEWHERE...WITH DISTINCT POSSIBILITY FOR
TORNADOES.

UPPER TROUGH SWINGS OUT OF ROCKIES...PUSHING CONVECTION EAST ON
SUNDAY. KEPT HIGH POPS IN WESTERN AR ON SUNDAY MORNING...WITH
DIMINISHING POPS THROUGH SUNDAY NIGHT.

GENERALLY ENHANCED POPS UP AND DOWN BASED ON MODEL AND HPC QPF
FIELDS. LEFT TEMPS PRETTY CLOSE TO MAV MOS...WITH SOME ADJUSTMENT
TO ECMWF AND PREVIOUS FORECAST. MODEL COMPARISONS WERE VERY CLOSE
THROUGH MID WEEK...AS WERE GFS ENSEMBLES.

...SEVERAL ROUNDS OF SEVERE WEATHER POSSIBLE TONIGHT THROUGH THE
WEEKEND...

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...TONIGHT.
TORNADO.
	RISK...ELEVATED.
	AREA...ALONG AND NORTH OF INTERSTATE 44.
	ONSET...ONGOING.

SEVERE THUNDERSTORM.
	RISK...ELEVATED.
 	AREA...NORTHEAST OKLAHOMA.
	ONSET...ONGOING.

FLASH FLOOD.
	RISK...LIMITED.
	AREA...NORTH OF INTERSTATE 44.
	ONSET...AFTER MIDNIGHT.

HEAVY RAIN.
	RISK...ELEVATED.
	AREA...NORTH OF INTERSTATE 44.
	ONSET...AFTER MIDNIGHT.

DISCUSSION...

A CLUSTER OF THUNDERSTORMS OVER NORTH CENTRAL AND NOW INTO
NORTHEAST OKLAHOMA WILL HAVE THE POTENTIAL OF BECOMING SEVERE
WITH THE POTENTIAL FOR LARGE HAIL TO GOLFBALL SIZE. AN ISOLATED
TORNADO THREAT EXISTS THROUGH THE EARLY MORNING WITH ANY DISCRETE
SUPERCELLS THAT CAN GET GOING.

THERE IS A SLIM CHANCE THAT SUPERCELL STORMS OVER SOUTHWEST OK
WILL MAKE IT OVER INTO EASTERN OK AFTER MIDNIGHT. IF THEY
DO...LARGE HAIL TO GOLFBALL SIZE AND ISOLATED TORNADOES WOULD BE
POSSIBLE.

SOME LOCALLY HEAVY RAIN AND POSSIBLE FLOODING IS
POSSIBLE...MAINLY NEAR THE KANSAS BORDER...IF STORMS OVER NORTH
CENTRAL OK END UP TRAINING OVER THE SAME AREAS.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
ACTIVATION OF THE REGIONAL SPOTTER NETWORK LIKELY.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY AND SUNDAY...SEVERE THUNDERSTORM POTENTIAL...HIGH WIND
POTENTIAL.
MONDAY THROUGH THURSDAY...NO HAZARDS.

EXTENDED DISCUSSION...

ANOTHER ROUND OF SEVERE WEATHER IS EXPECTED LATE SATURDAY AS
THUNDERSTORMS DEVELOP ALONG THE DRYLINE DURING THE AFTERNOON OVER
CENTRAL OKLAHOMA AND MOVE INTO EASTERN OKLAHOMA BY EVENING. STRONG
SHEAR AND INSTABILITY WILL ALLOW STORMS TO BECOME ORGANIZED AND
ROTATE. LOW LEVEL SHEAR WILL BE STRONGER ON SATURDAY...INCREASING
THE POTENTIAL FOR TORNADOES WITH ANY DISCRETE CELLS. THERE IS SOME
POTENTIAL FOR STRONG AND LONG-TRACK TORNADOES WITH THESE STORMS.

A SQUALL LINE WILL EVENTUALLY DEVELOP AFTER MIDNIGHT AS THE
PACIFIC FRONT SWEEPS EAST AND OVERTAKES THE DRYLINE. DAMAGING
WINDS BETWEEN 70 AND 80 MPH WILL BE POSSIBLE...ALONG WITH LARGE
HAIL TO 2 INCHES IN DIAMETER. GIVEN THE STRONG LOW LEVEL
SHEAR...SOME ISOLATED TORNADOES ARE POSSIBLE WITHIN THE LINE. STORMS
WILL SWEEP EAST ACROSS EASTERN OKLAHOMA LATE SATURDAY NIGHT INTO
SUNDAY MORNING AND INTO NORTHWEST ARKANSAS DURING THE DAY
SUNDAY...EXITING THE AREA BY SUNDAY NIGHT.

EMERGENCY MANAGEMENT PLANNING STATEMENT...

EMERGENCY MANAGERS AND FIRST RESPONDERS SHOULD CONTINUE TO MONITOR
THE WEATHER THROUGH THE WEEKEND AS SEVERAL ROUNDS OF POTENTIALLY
SIGNIFICANT SEVERE WEATHER COULD OCCUR OVER PORTIONS OF EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS.
