The radar

The Norman radar (KTLX), 43 km from the middle of the area, began a volume at 08:27 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 flash flood 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

Norman, OK (KOUN), launched 00:00Z, 8.4 hours before the alert went out and 40 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, Jun 4, 12:51 AM CDT, 2 hours 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
ISSUED BY NATIONAL WEATHER SERVICE TULSA OK
1251 AM CDT TUE JUN 4 2013

.AVIATION...
TSRA WILL BE ONGOING TONIGHT...WITH THE NORTHERN TAF SITES FOR THE
FIRST FEW HOURS WITH TEMPO MVFR CIGS AND VSBYS. STORMS SHOULD
DISSIPATE WITH TIME...WITH ALL SITES VFR FOR MOST OF THE TAF PERIOD.
ADDITIONAL CHANCES FOR STORMS WILL COME AFTER 00Z...AND WILL INCLUDE
A PROB GROUP FOR AFTER 00Z.

&&

.PREV DISCUSSION... /ISSUED 407 PM CDT MON JUN 3 2013/

SHORT TERM...TONIGHT THROUGH WEDNESDAY.
THE NEXT FEW DAYS WILL BRING CHANCES FOR STORMS AS A SERIES OF
SHORTWAVE TROUGHS MAKE THEIR WAY THROUGH OUR WEAK RIDGE. THERE
WILL BE ENOUGH INSTABILITY AND WIND SHEAR FOR SOME OF THESE STORMS
TO BECOME SEVERE. TONIGHT...THE GREATEST CHANCES FOR STORMS WILL
BE IN WESTERN OKLAHOMA. TUESDAY AND WEDNESDAY THESE CHANCES WILL
SPREAD TO THE REST OF THE REGION.

AS WE MOVE INTO WEDNESDAY AND THURSDAY MORNING...THE THREAT OF
FLASH FLOODING WILL INCREASE. LOCATION IS STILL UNCERTAIN...BUT A
FLASH FLOOD WATCH WILL LIKELY BE NEEDED IN FUTURE FORECASTS.

TEMPERATURES WILL CONTINUE ALONG A SLIGHT WARMING TREND UNTIL A
COLD FRONT COMES THROUGH ON WEDNESDAY DROPPING TEMPERATURES BELOW
NORMAL.

LONG TERM...THURSDAY THROUGH MONDAY.
WILL BEGIN THE MEDIUM RANGE PERIOD WITH WIDESPREAD SHOWER AND
THUNDERSTORM ACTIVITY. A SLOW MOVING COLD FRONT WILL CONTINUE TO
TRANSLATE SEWD AS AN UPPER WAVE MOVES INTO THE SOUTHEAST U.S.
MOIST TRANSPORT UP AND OVER THIS BOUNDARY MAY LEAD TO HEAVY
RAINFALL POTENTIAL EARLY THURSDAY...PARTICULARLY FOR LOCATIONS
SOUTH OF THE INTERSTATE 40 CORRIDOR. FLASH FLOODING MAY CONTINUE
TO BE A THREAT DURING THIS TIME AS PERSISTENT HEAVY RAINFALL IS
EXPECTED IN A FEW LOCATIONS. THE FRONT WILL CLEAR THE AREA BY
FRIDAY...ALLOWING FOR DRIER MORE STABLE AIR TO MOVE INTO OKLAHOMA
AND NORTH TEXAS. THIS SHOULD PREVENT MUCH IN THE WAY OF SHOWER AND
THUNDERSTORM ACTIVITY. THIS RESPITE WILL BE SHORT
LIVED...HOWEVER...AS SFC RIDGING MOVES EAST AND AN UPPER IMPULSE
SURGES THROUGH THE AREA. THIS WILL BRING SHOWER AND THUNDERSTORM
CHANCES INTO WESTERN OKLAHOMA AND WESTERN NORTH TEXAS AS EARLY AS
SATURDAY MORNING. WILL KEEP CHANCE POPS INTO SUNDAY AS LONG RANGE
MODELS CONTINUE TO DEPICT AN ACTIVE LATE SPRING RAINFALL PATTERN.
AS FOR TEMPERATURES...EXPECT SEASONABLY WARM WEATHER OVER AREAS
WHERE APPRECIABLE RAIN HAS FALLEN...GENERALLY IN THE 70S AND 80S.
FARTHER SOUTH...IN DROUGHT STRICKEN SOUTHWEST OKLAHOMA AND WESTERN
NORTH TEXAS...ARID EARTH WILL CONTRIBUTE TO MUCH WARMER AFTERNOON
TEMPERATURES...WHERE LOW TO MID 90S WILL BE COMMON. ONE BIT OF
GOOD NEWS...THE OVERALL THREAT OF ORGANIZED OR WIDESPREAD SEVERE
WEATHER LOOKS TO REMAIN LOW THROUGH THE EXTENDED PERIOD.
