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
Lamont, OK (KLMN), launched 00:00Z, 3.6 hours before the alert went out and 61 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.

.PREV DISCUSSION... /ISSUED 649 PM CDT SUN APR 3 2011/
AVIATION...
TIMING OF COLD FRONT/WIND SHIFT IS ADJUSTED TOWARD CONSENSUS OF
LATEST NAM RUC HRRR AND LOCAL WRF MODELS. GIVEN THE STRENGTH OF
THIS FRONT... THERE WILL LIKELY BE A PERIOD OF RELATIVELY
LIGHT/VARIABLE WINDS IN SOME AREAS FOR AN HOUR OR SO BEFORE THE
STRONGEST N/NNW WINDS DUE TO PRE-FRONTAL TROUGHS/WINDSHIFTS.
CONVECTION SHOULD REMAIN E OF THE TAF SITES TONIGHT BUT WE WILL
ADD SOME SHRA WITH THE FRONT IN THE KPNC VICINITY. SATELLITE
LOOPS SHOW A DECENT AMOUNT OF BLOWING DUST HEADED TOWARD SW OK SO
WE WILL MAINTAIN SOME SLIGHT VISIBILITY RESTRICTIONS AHEAD OF THE
FRONT EARLY THIS EVENING. RH PROGS AND CURRENT OBS SUPPORT A
PERIOD OF LOWER-END VFR OR BORDERLINE MVFR CIGS SEVERAL HOURS
AFTER THE FRONT... FOLLOWED BY CLEARING MONDAY. SFC WINDS
REMAINING QUITE STRONG OVERNIGHT INTO MONDAY BEFORE STARTING TO
DECREASE IN THE AFTERNOON.
PREV DISCUSSION... /ISSUED 237 PM CDT SUN APR 3 2011/
DISCUSSION...
THE DRYLINE... LOCATED ACROSS PORTIONS OF NW AND WEST-CENTRAL OK
THIS AFTERNOON... IS EXPECTED TO MOVE A LITTLE FARTHER EAST THROUGH
SUNSET BEFORE BECOMING STATIONARY A LITTLE WEST OF OKC AND SPS.
THE DRYLINE WILL THEN HOLD ITS POSITION... OR POSSIBLY DRIFT A
LITTLE BACK TO THE WEST... BEFORE A COLD FRONT OVERRUNS IT
TONIGHT.
RAIN/T-STORM CHANCES STILL LOOK NIL FOR THIS AFTERNOON AND PRETTY
SLIM FOR TONIGHT. A STRONG CAP WILL LIKELY HOLD THROUGH THE
REMAINDER OF THE AFTERNOON BEFORE WEAKENING LATER TONIGHT WITH THE
APPROACH OF THE UPPER LEVEL TROUGH. WE WILL MAKE ONLY SMALL
ADJUSTMENTS TO THE CURRENT FORECAST WHICH FAVORS THE HIGHEST POPS
IN THE EAST. PROVIDING THE CAP CONTINUES TO SUPPRESS ANY T-STORM
DEVELOPMENT ALONG THE DRYLINE THROUGH EARLY EVENING... WE ARE
THEN LOOKING AT A SCENARIO WHERE STORMS DEVELOP NEAR THE FRONT IN
EASTERN KS THIS EVENING AND BUILD SW ALONG THE FRONT... POSSIBLY
TO NEAR THE I35 CORRIDOR IN NORTHERN OK. THERE WILL ALSO BE ANOTHER CHANCE
FOR STORMS IN OUR AREA LATE TONIGHT AS THE FRONT MOVES INTO SOUTH
CENTRAL/SOUTHEAST OK. MEANWHILE... A FEW HIGH-BASED SHOWERS WILL
BE POSSIBLE ACROSS NORTHERN OK LATE TONIGHT AS LIFTING AHEAD OF
THE UPPER WAVE ACTS ON AN AREA OF MID LEVEL MOISTURE. HOWEVER MOST
OF THIS ACTIVITY WILL LIKELY WEAKEN AS IT MOVES EAST OFF THE
HIGHER TERRAIN IN THE WEST.
TEMPERATURES THIS EVENING WILL REMAIN QUITE MILD AHEAD OF THE
FRONT... ESPECIALLY EAST OF THE DRYLINE... BEFORE COOLING FAIRLY
QUICKLY AFTER FRONTAL PASSAGE. THE COLD FRONT SHOULD MOVE INTO NW
OK THIS EVENING AND REACH THE FAR SE PART OF THE CWA MONDAY
MORNING. PERSONNEL STILL WORKING ANY WILDFIRES TONIGHT WILL WANT TO
MONITOR THE PROGRESS OF THE FRONT AS THE WINDS WILL SHIFT SHARPLY
TO THE NORTH BEHIND IT AND GUST 35 TO 45 MPH. WE WILL CONTINUE THE
RED FLAG WARNING THROUGH THE EVENING. THE HIGH WINDS WILL CONTINUE
INTO MONDAY MORNING BEFORE GRADUALLY DECREASING IN THE AFTERNOON.
ALTHOUGH WIND SPEEDS MAY FALL BELOW WIND ADVISORY CRITERIA FOR A
WHILE THIS EVENING... THEY WILL JUMP BACK UP BEHIND THE FRONT.
IN THE LONGER TERM... GUSTY SOUTH TO SOUTHWEST WINDS ARE EXPECTED
TO DEVELOP TUESDAY AFTERNOON AS THE SURFACE RIDGE SHIFTS TO THE
EAST WHILE THE SURFACE TROUGH DEEPENS OVER THE SOUTHERN HIGH
PLAINS. THE GUSTY WINDS ALONG WITH WARMING TEMPERATURES AND LOW
HUMIDITIES WILL AGAIN RAISE FIRE WEATHER CONCERNS.
A WEAK FRONT WILL MOVE INTO THE AREA ON WEDNESDAY WHICH SHOULD
DECREASE THE SURFACE WINDS... HOWEVER... RAIN CHANCES WILL BE
NIL WITH THIS SYSTEM. A STRONGER SYSTEM WILL MOVE ACROSS THE AREA
ON THURSDAY BUT ONCE AGAIN IT APPEARS THAT ANY PRECIP WILL LIKELY
BE JUST EAST OF THE FA. RAIN CHANCES WILL IMPROVE SOMEWHAT FRIDAY
NIGHT... AND CONTINUE INTO THE WEEKEND... AHEAD OF A LARGE UPPER
LOW OVER THE SW US.

INTO CENTRAL OKLAHOMA IF THE CAPPING INVERSION WEAKENS SUFFICIENTLY
THIS EVENING AND OVERNIGHT. THE MOST LIKELY AREA FOR THUNDERSTORM
DEVELOPMENT WILL BE EAST OF INTERSTATE 35. IF THUNDERSTORMS DO
DEVELOP... INSTABILITY AND WIND SHEAR WILL BE SUFFICIENT FOR THESE
THUNDERSTORMS TO BECOME SEVERE... CAPABLE OF PRODUCING LARGE HAIL
AND DAMAGING THUNDERSTORM WINDS.
PROBABILITY TABLE...
VALID THROUGH 700 AM CDT MONDAY APR 4.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
NWS NORMAN COUNTY WARNING AREA...30 PERCENT.
