The radar
The Altus AFB radar (KFDR), 65 km from the middle of the area, began a volume at 06:19 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
Fort Worth, TX (KFWD), launched 00:00Z, 6.3 hours before the alert went out and 170 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.

Area forecast discussion, Mar 26, 9:28 PM CDT, 3 hours 48 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 928 PM CDT SAT MAR 26 2016 .DISCUSSION... APPEARS PART OF NORTHWEST OKLAHOMA WILL SEE MAINLY A WET SNOW AFTER 1-2 AM. OVERALL IMPACT SHOULD BE REDUCED VISIBILITY WITH SNOW ACCUMULATIONS CONFINED TO GRASSY AREAS. RAIN MAY ALSO CHANGE TO SNOW AS FAR EAST AS ENID AND PONCA CITY PER RAP SOUNDINGS. MAIN AREA OF PRECIPITATION SHOULD MOVE INTO FAR WESTERN OKLAHOMA BETWEEN 10-11 PM. A FEW STRONG TO SEVERE STORMS WILL LIKELY FORM OVER SOUTHWESTERN OKLAHOMA AND WESTERN NORTH TEXAS AS WELL. && .PREV DISCUSSION... /ISSUED 241 PM CDT SAT MAR 26 2016/ DISCUSSION... PRECIPITATION CHANCES AND STRONG TO SEVERE STORM POTENTIAL TONIGHT ARE THE MAIN CONCERNS. TONIGHT...MOISTURE AND LIFT WILL INCREASE ACROSS THE ENTIRE AREA AHEAD OF THE MID/UPPER LEVEL DISTURBANCE CURRENTLY OVER COLORADO. SHOWERS AND PERHAPS THUNDERSTORMS WILL MOVE INTO WESTERN OKLAHOMA SOMETIME IN THE 9 PM TO MIDNIGHT TIME FRAME. ADDITIONAL THUNDERSTORMS MAY FORM AHEAD OF THIS ACTIVITY NEAR THE 850 MB FRONT ACROSS SOUTHWESTERN OKLAHOMA AND WESTERN NORTH TEXAS IN THE 10 PM TO 1 AM TIME RANGE. OVERALL...INCREASED RAIN CHANCES TONIGHT IN MANY AREAS. SOME LOCATIONS COULD GET 0.50 TO 1 INCH OF RAIN. AS FAR AS SEVERE THUNDERSTORM POTENTIAL IS CONCERNED TONIGHT...THINK A FEW SEVERE STORMS WITH LARGE HAIL UP TO HALF DOLLARS COULD OCCUR OVER MAINLY THE SOUTHERN HALF OF OKLAHOMA AND WESTERN NORTH TEXAS. FORECAST MUCAPE IN THE 500 TO 1000 J/KG COMBINED VERY STRONG 0-6 KM SHEAR OF 45-75 KT SUPPORT MAINLY ELEVATED SUPERCELLS AND MULTICELLS CAPABLE OF LARGE HAIL. CANNOT COMPLETELY RULE OUT A DAMAGING WIND GUST OR TWO OF AROUND 60 MPH...ESPECIALLY SOUTHEAST OF A WICHITA FALLS TO PURCELL TO SEMINOLE LINE WHERE SURFACE DEWPOINTS WILL BE HIGHEST NEAR AND JUST SOUTHEAST OF A DEVELOPING COLD FRONT. NOT EXPECTING MANY SEVERE REPORTS. APPEARS MOST...IF NOT ALL...SEVERE STORMS SHOULD STAY SOUTH OF THE OKLAHOMA CITY METRO AREA...WHICH SHOULD BE AFFECTED BY STORMS IN THE 2 TO 5 AM TIME FRAME. ONGOING SPC MARGINAL RISK AREA IN THE 11 PM TO 7 AM TIME FRAME APPEARS TO BE VERY REASONABLE. THERE IS A CHANCE FOR RAIN TO MIX WITH OR TURN OVER TO SNOW IN NORTHWESTERN OKLAHOMA AFTER MIDNIGHT TONIGHT. KEPT THIS MENTION NORTH OF A CHEYENNE TO WATONGA TO PONCA CITY LINE...PER LATEST MODEL GUIDANCE...RELYING MORE HEAVILY ON THE LATEST HRRR/RUC13 RUNS. RIGHT NOW...NOT EXPECTING ANY IMPACTS FROM ANY SNOW...BUT COULD NOT COMPLETELY RULE OUT A DUSTING UP TO AN INCH IN SOMEWHERE. ANY SNOW WOULD HAVE A DIFFICULT TIME ACCUMULATING DUE TO WARM GROUND CONDITIONS. SUNDAY...PRECIPITATION MAY LINGER BEFORE 10 AM NEAR AND EAST OF I-35. RAPID CLEARING CAN BE EXPECTED LATE MORNING INTO EARLY AFTERNOON. MODEL GUIDANCE HIGHS IN THE UPPER 50S TO LOWER 60S SEEMED TO BE REASONABLE. NORTH SURFACE WINDS WILL DECREASE THROUGH THE AFTERNOON HOURS. SUNDAY NIGHT...CLEAR AND COLD CONDITIONS ARE FORECAST WITH A SURFACE HIGH OVERHEAD. FREEZING OR SUBFREEZING TEMPERATURES MAY BE POSSIBLE IN RURAL LOCATIONS...ESPECIALLY IN NORTHERN OKLAHOMA. FOR NOW...DID NOT ISSUE A FREEZE WATCH DUE TO SOME UNCERTAINTY ON HOW COLD IT WILL GET. WENT BELOW MODEL GUIDANCE LOWS THINKING CALM WINDS...CLEAR SKIES...AND DRY AIR WILL ALLOW FOR EXCELLENT RADIATIONAL COOLING. MONDAY...SOUTHERLY SURFACE WINDS WILL FORM AND INCREASE... ESPECIALLY IN WESTERN OKLAHOMA. DRY AND SLIGHTLY WARMER CONDITIONS ARE FORECAST. TUESDAY THROUGH THURSDAY...WILL MONITOR FOR VERY HIGH WILDFIRE CONCERNS AND STRONG TO SEVERE THUNDERSTORM POTENTIAL DURING THIS TIME FRAME. A DRYLINE WILL LIKELY BE OVER THE SOUTHERN PLAINS WITH HOT...DRY...AND WINDY CONDITIONS WEST OF IT...AND WARM AND HUMID CONDITIONS EAST OF THIS LINE. POTENTIAL INSTABILITY WILL INCREASE EAST OF THE DRYLINE...WHICH COMBINED WITH STRONG SHEAR...WOULD FAVOR SOME SEVERE THUNDERSTORM POTENTIAL...PARTICULARLY WEDNESDAY AND WEDNESDAY NIGHT AS A MID/UPPER TROUGH APPROACHES THE SOUTHERN PLAINS. WILL CLOSELY MONITOR. TEMPERATURES WILL REMAIN ABOVE AVERAGE. FRIDAY AND NEXT SATURDAY...DRY AND COOLER WEATHER IS FORECAST... THOUGH CONFIDENCE IS RATHER LOW. MBS FIRE WEATHER...
