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
Amarillo Airport, TX (KAMA), launched 12:00Z, 7.6 hours before the alert went out and 80 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.

.AVIATION...
AN UPPER LOW OVER BAJA CA WILL LIFT NORTHEASTWARD AND APPROACH THE
PANHANDLES BY SATURDAY MORNING. SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS WILL BE LIKELY THROUGH TONIGHT AND INTO SATURDAY
MORNING. IFR TO MVFR CONDITIONS CAN BE EXPECTED IN AND AROUND THE
CONVECTION...WHILE VFR CONDITIONS CAN BE EXPECTED OUTSIDE THE SHOWERS
AND STORMS. SOUTHERLY WINDS OF 15 TO 25 MPH WITH HIGHER GUSTS WILL BE
POSSIBLE ACROSS THE PANHANDLES. SOME STORMS MAY REACH SEVERE LEVELS
AND ALSO PRODUCE VERY HEAVY RAINFALL WHICH COULD RESULT IN LOCALIZED
FLOODING.

.PREV DISCUSSION... /ISSUED 1227 PM CDT FRI MAR 23 2007/
UPDATE...
WILL UPDATE PRODUCTS MAINLY FOR CURRENT TRENDS AND TEMPORAL WORDING.
THE THUNDERSTORM THAT JUST MOVED ACROSS AMA IS A SIGN OF THINGS TO
COME ASSUMING WE CAN SCOUR OUT SOME OF THIS CLOUD COVER AND GET SOME
SURFACE HEATING. GFSBUFR PROG SOUNDINGS ARE SHOWING SBCAPES NEAR
2000J/KG THIS AFT ASSUMING WE CAN ACHIEVE MAX HEATING. SHEAR PROFILES
SUPPORT LARGE HAIL OVER ANY TORNADO THREAT. AN 18Z SOUNDING WILL BE
RELEASED TO SUPPORT ANY POTENTIAL SVR WX THIS PM. THE SEVERE THREAT
IS STILL EXPECTED TO TRANSITION TO A FLASH FLOODING THREAT TONIGHT AS
LARGE SCALE FORCING INCREASES WITH THE APPROACH OF THE UPPER LOW. FFA
HAS BEEN REISSUED TO COVER THIS THREAT.

DISCUSSION...
LARGE UPPER LEVEL CUTOFF LOW OVER BAJA CALIFORNIA IS EXPECTED TO
START LIFTING NORTHEAST ACROSS NORTHWEST MEXICO AND THEN ACROSS NEW
MEXICO THROUGH EARLY THIS WEEKEND. SUBTROPICAL PLUME HAS MOVED TO THE
EAST OF THE REGION...WHICH SHOULD ALLOW THE SUN TO WORK ON THE LOW
LEVEL MOISTURE THAT WILL BE BACKED ALL THE WAY UP TO THE MOUNTAINS IN
SOUTHEAST NEW MEXICO. ABUNDANT LOW LEVEL MOISTURE COMBINED WITH
DECENT MID LEVEL LAPSE RATES AND THE UPPER LEVEL JET APPROACHING
SOUTHEAST NEW MEXICO/WEST TEXAS WILL ALLOW FOR WIDESPREAD CONVECTION
TO DEVELOP THIS AFTERNOON ACROSS THE SOUTHEAST NEW MEXICO INTO WEST
TEXAS. THIS WHOLE SHIELD OF THUNDERSTORMS SHOULD THEN LIFT NORTH
NORTHEAST ACROSS THE PANHANDLES LATE THIS AFTERNOON INTO TONIGHT. WE
ALSO CAN NOT RULE OUT SOME CONVECTION DEVELOPING OVER OUR CWA IF
DAYTIME HEATING IS REALIZED. THE THUNDERSTORMS WILL PROBABLY DEVELOP
ALONG THE OLD OUTFLOW BOUNDARIES LEFT OVER FROM YESTERDAY/S
CONVECTION. SOME SEVERE STORMS WILL BE POSSIBLE GIVEN THE SHEAR
PROFILES AND THE INSTABILITY...SEE THE LATEST SWODY1 PRODUCT FROM SPC
FOR ALL OF THE DETAILS. WE WILL ALSO BE CONCERNED ABOUT HEAVY RAIN
GIVEN THE AMOUNT OF MOISTURE THAT THESE STORMS WILL BE ABLE TO FEED
ON. THE STORMS WILL ALSO TEND TO TO TRAIN GIVEN THE UPPER LEVEL WIND
PROFILES AND DIVERGENT FLOW ALOFT. THEREFORE...HAVE DECIDED TO ISSUE
A FLASH FLOOD WATCH FOR THE ENTIRE CWA FROM THIS AFTERNOON THROUGH
SATURDAY MORNING.
AGREE WITH EARLIER SHIFT THAT THIS UPPER LEVEL LOW MAY BE SLOW TO
LIFT OUT...MAYBE SLOWER THAN WHAT THE MODELS HAVE GOING. BOTH THE
NAM AND THE GFS ARE IN GOOD AGREEMENT ON THE MOVEMENT OF THE 500 MB
LOW CENTER...BUT WILL CONTINUE TO GO WITH A SLIGHTLY SLOWER
SOLUTION AND KEEP PRECIP IN THE FORECAST THROUGH SUNDAY. ALSO IT
LOOKS LIKE THE REST OF THE TROUGH THAT THE UPPER LOW LEAVES BEHIND
MOVES ACROSS THE AREA ON SUNDAY.
ONCE UPPER LOW LIFTS NORTHEAST AND AWAY FROM THE PANHANDLES...FLOW
BECOMES ZONAL AND SKIES CLEAR AND TEMPERATURES WARM UP AGAIN.
HOWEVER...ANOTHER STRONG UPPER LOW MOVES ACROSS THE CENTRAL ROCKIES
ON WEDNESDAY AND MOST OF THE PANHANDLES WILL LIKELY GET DRY
SLOTTED...BUT DRYLINE MAY HOLD IN THE EASTERN CWA LONG ENOUGH TO
GET STORMS GOING THERE...SO WILL LEAVE POPS AS IS.
OUTSIDE OF THE FIRST COUPLE OF DAYS...WENT WITH THE GFS MODEL FOR
TEMPERATURES IN THIS FORECAST.
THANKS FOR THE COORDINATION LUB AND PUB.
