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.

PREV DISCUSSION... /ISSUED 807 AM CDT WED MAY 14 2008/
DISCUSSION...QUICK UPDATE TO THE FORECAST FOR NEWLY ISSUED
TORNADO WATCH ISSUED FOR THE TEXAS LAKES AND PART OF CENTRAL
LOUISIANA UNTIL 20Z OR 3 PM. TWEAKED POPS JUST A LITTLE FOR
TODAY...BUT OTHERWISE NO OTHER CHANGES.
PREV DISCUSSION... /ISSUED 552 AM CDT WED MAY 14 2008/
DISCUSSION...WATER VAPOR SATELLITE/UPPER AIR ANALYSIS THIS
MORNING SHOWED UPPER RIDGE CENTERED NEAR THE TIP OF THE
YUCATAN...WITH A MEAN UPPER TROF AXIS FROM THE UPPER MIDWEST TO
THE DESERT SOUTHWEST. SHORTWAVE NOTED AT THE BASE OF THIS TROF
SPINNING TOWARD SOUTHWEST NEW MEXICO...WHILE SMALLER SCALE
PERTURBATIONS CONTINUE TO LIFT THROUGH THE SOUTHWEST FLOW ALOFT
BETWEEN THE UPPER TROF AND RIDGE.
AT THE SFC...LOW PRESSURE ANALYZED OVER SOUTHEAST NEW MEXICO WITH A
FRONTAL BOUNDARY EXTENDING TO THE EAST TO BETWEEN DALLAS AND
WICHITA FALLS...THEN NORTHEAST THROUGH SOUTHEAST OKLAHOMA AND ON
INTO MISSOURI.
KLCH 00Z RAOB SHOWED A PWAT OF 1.73 INCHES...WHICH IS FORECAST TO
CLIMB TO AOA 2 INCHES TODAY. THIS WOULD BE NEAR 2 STANDARD
DEVIATIONS ABOVE NORMAL FOR THIS TIME OF YEAR.
SEVERAL CONVECTIVE CLUSTERS HAVE BEEN ONGOING ACROSS THE SOUTHERN
PLAINS THIS MORNING...GENERALLY WITHIN THE AFOREMENTIONED SOUTHWESTERLY
FLOW BETWEEN THE UPPER RIDGE TO THE SOUTH AND UPPER TROF AXIS TO
THE WEST.
THOUGH THERE IS CONFIDENCE IN THE OVERALL SYNOPTIC FORECAST FOR THE
NEXT FEW DAYS...THE DEVIL IS IN THE MESOSCALE DETAILS. SHORTWAVE OVER
SW NM PROGGED TO LIFT OUT AND FILL OVER THE NEXT 24 TO 36 HRS...WHILE
HEIGHTS SLOWLY FALL OVER THE AREA AS RIDGE TO THE SOUTH IS PROGRESSIVELY
ERODED. MEANWHILE...FRONTAL BOUNDARY WILL CONTINUE TO MAKE SLOW
BUT STEADY PROGRESS TO THE SOUTHEAST. MOIST AND GENERALLY UNCAPPED
AIRMASS WILL REMAIN IN PLACE TO THE SOUTH OF THE FRONTAL BOUNDARY
TODAY...WITH CONVECTIVE ACTIVITY DEPENDENT ALMOST ENTIRELY ON
DIFFICULT TO FORECAST MESOSCALE BOUNDARIES...WEAK PERTURBATIONS
MOVING THROUGH THE FLOW ALOFT...OR PROPAGATION/MOVEMENT OF UPSTREAM
CONVECTION INTO THE AREA.
INHERITED FORECAST HAD 30 TO 50 POPS FOR TODAY SOUTH TO
NORTH...AND THAT CONTINUES TO LOOK GOOD ABSENT ANYTHING CONCRETE
FOR ME TO HANG MY HAT ON...OTHER THAN TO SAY NORTHERN AREAS WILL
HAVE A BETTER SHOT BEING CLOSER TO THE RING OF FIRE.
SPC HAS AREA WITHIN SLIGHT RISK ON THE DAY ONE OUTLOOK...AND THAT
IS REASONABLE GIVEN THE SHEAR ENVIRONMENT. WILL ALSO HAVE TO BE
ALERT FOR LOCALIZED HEAVY RAINFALL/FLOODING EVENTS...SINCE THE
EXCEEDINGLY HIGH MOISTURE CONTENT OF THE ATMOSPHERE WILL RESULT IN
VERY EFFICIENT RAIN PRODUCING THUNDERSTORMS.
FOR TOMORROW...EVEN THOUGH THE SHORTWAVE WILL HAVE LIFTED
OUT...MEAN TROF AXIS WILL REMAIN TO THE WEST...KEEPING THE
SOUTHWESTERLY FLOW ALOFT IN PLACE. IN ADDITION...FRONTAL BOUNDARY
WILL CONTINUE DRAW CLOSER TO THE AREA THROUGH THE DAY...AND FINALLY
PROGRESSING THROUGH THE AREA THURSDAY NIGHT. LIKELY POPS ARE ON
TARGET AS THE AXIS OF CONVECTIVE DEVELOPMENT SHOULD SHIFT FARTHER
TO THE SOUTH. INCREASED RAIN CHANCES A LITTLE THURSDAY...AND
THURSDAY NIGHT WITH THE SURFACE BOUNDARY PASSING THROUGH. LEFT
FRIDAY ALONE FOR THE TIME BEING...THOUGH A LINGERING CHANCE MAY BE
WARRANTED OVER SOME INLAND AREAS IN ADDITION TO THE COASTAL WATERS
THAT ALREADY HAVE A SLIGHT CHANCE.
THE WEEKEND LOOKS FINE AS SFC HIGH PRESSURE SETTLES IN BEHIND THE
FRONT. FORECAST BEYOND THIS IS FRAUGHT WITH UNCERTAINTY...THOUGH I
GENERALLY FOLLOWED THE ECMWF...WHICH SHOWS A WARMING PATTERN EARLY
NEXT WEEK WITH MINIMAL RAIN CHANCES.
AVIATION...CLOUDS GENERALLY VFR TODAY...WITH PERIODS MVFR THIS
MORNING. SHRA/TSRA POSSIBLE TODAY...BUT LOW CONFIDENCE IN TIMING
AND PLACEMENT PREVENT INSERTING ANYTHING OTHER THAN VICINITY...EXCEPT
KAEX WHERE A PROB GROUP WAS USED FOR THIS AFTERNOON.
MARINE...MODEST SOUTHERLY FETCH WILL CONTINUE UNTIL FRONT PASSES
THROUGH COASTAL WATERS THURSDAY NIGHT INTO FRIDAY MORNING. HOISTED
SCEC FOR WATERS BEYOND 20NM FOR TODAY...AND WILL REMAIN NEAR THIS
THRESHOLD UNTIL FROPA. MODEST OFFSHORE FLOW WILL DEVELOP IN THE
WAKE OF THE FRONT...WITH WINDS AND SEAS BOTH SUBSIDING OVER THE
WEEKEND AS SFC HIGH PRESSURE PREVAILS.

THE PRIMARY THREATS FROM ANY SEVERE STORMS THAT DEVELOP WOULD BE LARGE HAIL AND DAMAGING WINDS...BUT ISOLATED TORNADOES CANNOT BE RULED OUT.

LOCALIZED FLOODING COULD BE POSSIBLE...ESPECIALLY IN URBAN AREAS AND WHERE TRAINING STORMS OCCUR. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY THE CHANCE FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE THURSDAY INTO THURSDAY NIGHT...UNTIL A COLD FRONT MOVES THROUGH THE AREA LATE THURSDAY NIGHT INTO FRIDAY MORNING.
