What happened
The episode as NWS OUN wrote it up.
A warm front/dryline triple point was present across far northwestern Oklahoma during the daylight hours. As a weak shortwave moved across the Southern Plains, strong flow aloft overspread the region. Daytime heating and the influence of the upper wave lifted the cap, allowing for scattered severe thunderstorm development.
What forecasters said that day
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Norman, OK wrote its last area forecast discussion before the first event at Apr 8, 1:40 PM CST, 1 hour 35 minutes earlier.
Area forecast discussion, Apr 8, 1:40 PM CST, 1 hour 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 240 PM CDT WED APR 8 2015 .DISCUSSION... THE MAIN CONCERNS THIS FORECAST WILL CENTER AROUND SEVERE WEATHER POTENTIAL ACROSS PARTS OF OKLAHOMA AND NORTH TEXAS LATE TODAY THROUGH TONIGHT...AND A CONTINUED RISK OF SEVERE WEATHER ALONG WITH HEIGHTENED WILDFIRE POTENTIAL TOMORROW. WIDESPREAD MID LEVEL CLOUDINESS CONTINUES EARLY THIS AFTERNOON IN ASSOCIATION WITH LIFT SUPPLIED BY AN UPPER WAVE EARLIER TODAY. THIS HAS LIMITED HEATING TO SOME DEGREE SOUTH OF A NEARLY STATIONARY FRONTAL BOUNDARY EXTENDING FROM NEAR ARNETT TO CHEROKEE. HOWEVER...WITH STRONG SOUTHERLY FLOW...AND SPORADIC SHOWER ACTIVITY...MOISTURE APPEARS TO BE INCREASING SOUTH OF THIS BOUNDARY ACROSS PORTIONS OF NORTH CENTRAL AND NORTHWESTERN OKLAHOMA. THIS FRONT...ALONG WITH A DRYLINE ACROSS FAR WESTERN OKLAHOMA INTO THE TEXAS PANHANDLE...WILL BE THE FOCUS OF INITIAL THUNDERSTORM DEVELOPMENT LATER THIS AFTERNOON THROUGH THIS EVENING. DESPITE SLOW WARMING ACROSS MUCH OF THE WARM SECTOR...AMPLE MOISTURE AND A STOUT CAPPING INVERSION...ALONG WITH STEEP MID LEVEL LAPSE RATES HAVE LED TO SUBSTANTIAL INSTABILITY ACROSS MUCH OF THE REGION. AS A POTENT MID LEVEL JET OVERSPREADS THE REGION THROUGH THE REMAINDER OF TODAY AND TONIGHT...WIND SHEAR WILL BE ON THE RISE. THESE PARAMETERS WILL BE MORE THAN FAVORABLE FOR A SUPERCELLULAR STORM MODE...WITH POTENTIAL FOR VERY LARGE HAIL AND DAMAGING WINDS WITH ANY STORM. IN ADDITION...A NOTED TORNADO THREAT WILL EXIST...ESPECIALLY NEARER THE STALLED FRONTAL BOUNDARY OVER NORTHERN OKLAHOMA TOWARD SUNSET AS LOW LEVEL WIND SHEAR INCREASES. THIS IS CERTAINLY THE AREA WITH THE HIGHEST CONFIDENCE IN STORM COVERAGE. FURTHER SOUTH...STORM INITIATION WILL LARGELY BE DRIVEN BY MIXING ALONG THE DRYLINE. STORMS MAY INITIALLY BE RATHER HIGH BASED...BUT CLOUD BASES SHOULD LOWER AS STORMS MOVE INTO THE MOISTURE RICH ENVIRONMENT EAST OF THE DRYLINE. HIGH RES MODELS DEPICT STORMS MAY STRUGGLE TO PERSIST WITHIN A STRONGLY CAPPED ENVIRONMENT OVER CENTRAL AND SOUTHERN OKLAHOMA EAST OF THE DRYLINE...BUT A THREAT OF AT LEAST ISOLATED SUPERCELL STORMS WILL EXIST INTO THIS EVENING AND EARLY TONIGHT. WHILE SOME TORNADO POTENTIAL WILL STILL EXIST WITH ANY STORM THAT CAN MOVE INTO CENTRAL OR SOUTHERN OKLAHOMA THIS EVENING/OVERNIGHT...THE MORE SUPPORTIVE ENVIRONMENT WILL REMAIN ALONG AND NORTH OF A STILLWATER TO CLINTON LINE...NEAR THE AFOREMENTIONED STATIONARY FRONT. OVERNIGHT...ADDITIONAL STORMS MAY DEVELOP AS MORE UPPER LEVEL ENERGY OVERSPREADS THE SOUTHERN AND CENTRAL PLAINS. THE SEVERE THREAT MAY PERSIST WITH THESE STORMS THROUGH AROUND MIDNIGHT...THOUGH THE PRIMARY HAZARDS WILL LIKELY TRANSITION TO MORE OF A HAIL AND WIND THREAT AS THE BOUNDARY LAYER GRADUALLY STABILIZES. A STRONG FRONT WILL SWEEP THROUGH OKLAHOMA AND NORTH TEXAS OVERNIGHT TONIGHT INTO TOMORROW. ELEVATED WILDFIRE POTENTIAL WILL EXIST IN THE BREEZY WARM POST-FRONTAL AIRMASS ACROSS WESTERN OKLAHOMA THURSDAY AFTERNOON. A RISK OF SEVERE STORMS WILL ALSO EXIST AHEAD OF THE FRONT OVER MAINLY SOUTHEASTERN OKLAHOMA. LARGE HAIL AND DAMAGING WINDS WILL BE THE PRIMARY CONCERNS. A BRIEF RESPITE IN SHOWERS/STORMS LOOKS TO TAKE PLACE FRIDAY...BUT AN ACTIVE PATTERN WILL BECOME REESTABLISHED BY SATURDAY AS SEVERAL UPPER TROUGHS ROLL ACROSS THE SOUTHERN AND CENTRAL PLAINS IN A MOIST AND UNSTABLE ENVIRONMENT. SOME SEVERE POTENTIAL WILL LIKELY EXIST ON CERTAIN DAYS NEXT WEEK...BUT MODELS REMAIN TOO INCONSISTENT TO POINT TO ANY PARTICULAR DAYS. AUSTIN && .PRELIMINARY POINT TEMPS/POPS...

WESTERN...CENTRAL...AND SOUTHERN OKLAHOMA...AND WESTERN NORTH TEXAS. .DAY ONE...THIS AFTERNOON AND TONIGHT... .THUNDERSTORMS... THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING ACROSS A SMALL PART OF NORTH CENTRAL OKLAHOMA. THE REST OF NORTHERN...WESTERN AND CENTRAL OKLAHOMA AND NORTH TEXAS ARE IN AN ENHANCED TO SLIGHT RISK AREA. TORNADOES ARE POSSIBLE. LOCATION... AREAS ALONG AND EAST OF WAKITA AND ENID AND NORTH OF ENID AND RED ROCK ARE IN THE MODERATE RISK AREA. AREAS EAST OF WOODWARD AND CLINTON...AND GENERALLY NORTH OF CLINTON AND OKLAHOMA CITY ARE IN THE ENHANCED RISK. THE SLIGHT RISK COVERS NORTH TEXAS AND THE REST OF CENTRAL AND WESTERN OKLAHOMA TO THE NORTHWEST OF HOLDENVILLE AND ARDMORE. TIMING... 4 PM TO MIDNIGHT IMPACTS... HAIL TO TENNIS BALL SIZE...WIND GUSTS TO 70 MPH AND A FEW TORNADOES. DISCUSSION... SCATTERED SHOWERS AND A FEW THUNDERSTORMS WILL MOVE ACROSS CENTRAL AND EASTERN OKLAHOMA DURING THE EARLY TO MID AFTERNOON. SMALL HAIL AND OCCASIONAL LIGHTNING ARE POSSIBLE WITH SOME OF THE STORMS. BY LATE AFTERNOON...ISOLATED THUNDERSTORMS WILL FORM ALONG A DRYLINE IN FAR WESTERN OKLAHOMA AND ADJACENT AREAS OF NORTH TEXAS. OTHER STORMS ARE EXPECTED TO DEVELOP IN FAR NORTHERN OKLAHOMA NEAR A WARM FRONT. STORMS THAT DEVELOP WILL LIKELY BECOME SEVERE AND MOVE NORTHEAST AROUND 25 MPH. MODERATE TO STRONG CAPE AND INCREASING DEEP LAYER SHEAR WILL SUPPORT THE DEVELOPMENT OF VERY LARGE HAIL AND DAMAGING WINDS. BY EARLY EVENING... LOW LEVEL WIND SHEAR WILL INCREASE WITH THE DEVELOPMENT OF A LOW LEVEL JET. THIS WILL INCREASE THE CHANCE OF TORNADOES...ESPECIALLY IN NORTH CENTRAL OKLAHOMA. STORMS THAT FORM IN WESTERN OKLAHOMA WILL APPROACH CENTRAL AND SOUTHERN OKLAHOMA AFTER 8 PM. BY MIDNIGHT...STORM INTENSITY WILL GRADUALLY DECREASE AND STORMS SHOULD MOVE NORTH AND EAST OF THE AREA. .SPOTTER AND EMERGENCY MANAGEMENT STATEMENT... STORM SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL ACROSS NORTHERN AND CENTRAL OKLAHOMA SHOULD PREPARE FOR SEVERE WEATHER OPERATIONS LATE THIS AFTERNOON AND EVENING. .FIRE WEATHER... THERE IS A RED FLAG WARNING FOR THIS AFTERNOON AND EARLY EVENING IN WESTERN OKLAHOMA. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY... A COLD FRONT WILL MOVE INTO SOUTHEAST OKLAHOMA THURSDAY AFTERNOON WITH FAVORABLE MOISTURE AND UPPER LEVEL SUPPORT FOR THUNDERSTORMS. THERE IS A SLIGHT RISK FOR SEVERE THUNDERSTORMS EAST OF DURANT AND ATOKA. A CHANCE OF THUNDERSTORMS CONTINUES UNTIL TUESDAY.
