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 tornado 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

Shreveport, LA (KBAD), launched 12:00Z, 11.0 hours before the alert went out and 118 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, May 24, 5:01 PM CDT, 56 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
501 PM CDT SUN MAY 24 2015

.DISCUSSION...
HAVE CANCELLED THE TORNADO WATCHES NUMBER 202 AND 204 FOR THE
FOUR STATE REGION WITH ONLY ONE STORM LEFT IN CALDWELL PARISH THAT
WOULD POSE A THREAT TO BECOMING SEVERE. EXPECTING ADDITIONAL
DEVELOPMENT TO OCCUR DURING THE REMAINDER OF THE AFTERNOON AND
INTO THE EVENING OVER PARTS OF EAST AND NORTHEAST TEXAS...
NORTHWEST AND NORTH CENTRAL LOUSIAIANA...AND SOUTHWEST AND SOUTH
CENTRAL ARKANSAS IN WAKE OF THE DEPARTING BAND THAT BROUGH
STRONG TO SEVERE THUNDERSTORMS EARLIER IN THE DAY. THERE MAY BE
SOME LOCALLY HEAVY RAINFALL WITH ANY THUNDERSTORMS THAT DEVELOP
AND WILL KEEP THE FLASH FLOOD WATCH GOING SINCE WE HAD RAIN AT
JUST ABOUT ALL SITES. THE UPPER LEVEL SHORT WAVE THAT HELPED
PRODUCE THE SHOWERS AND THUNDERSTORMS HAS SHIFTED OFF TO THE EAST
AND NORTHEAST BUT ON ITS HEELS ANOTHER ONE OVER NORTH CENTRAL
TEXAS WILL COMBINE WITH AVAILABLE MOISTURE AND REMAINING
UNSTABLE CONDITIONS TO PROVIDE FOR ADDITIONAL DEVELOPMENT.
THERE WILL BE A BREAK LATER DURING THE OVERNIGHT HOURS AND INTO
THE EARLY MORNING HOURS FROM RAIN...BUT ANOTHER STRONG SHORT WAVE
THAT WILL BECOME NEGATIVE TILTED...SHIFT EAST AND NORTHEAST ACROSS
TEXAS AND INTO THE FOUR STATE REGION...AND PRODUCE THE NEXT ROUND
OF SHOWERS AND THUNDERSTORMS. THESE LOOK TO DEVELOP AND START TO
AFFECT PARTS OF EAST TEXAS AND SOUTHEAST OKLAHOMA NEAR MID DAY TO
LATE MORNING AND THEN SPREAD ACROSS THE REMAINDER OF THE FOUR
STATE REION INTO THE AFTERNOON MONDAY AND OVERNIGHT. THE STORMS
WILL BE STRONG TO SEVERE ALONG WITH PRODUCING LOCALLY HEAVY
RAINFLL...WITH STRONG AND DAMAGING WINDS...POSSIBLY LARGE
HAIL...AND ISOLATED TORNADOES MONDAY AFTERNOON AND OVERNIGHT.
ADDITIONAL RAINFALL FROM THIS BAND OF RAIN ON MONDAY AND OVERNIGHT
WILL PROVIDE ADDITIONAL TWO TO FOUR INCHES...WITH A HIGH POTENTIAL
OF FLASH FLOODING DEVELOPING...SINCE GROUNDS WILL STILL BE NEAR
SATURATION AND HIGH WATER IN ALL RIVERS...CREEKS...AND LAKES.
HEAVY RAINFALL WILL BE POSSIBLE INTO THE AFTERNOON TUESDAY FOR THE
DEEP EAST TEXAS LAKES AREA AND ACROSS LOWER PARTS OF NORTHWEST AND
INTO NORTH CENTRAL LOUISIANA. AN UNSETTLED WEATHER PATTERN WILL
CONTINUE THROUGH THE REST OF THE WORK WEEK AS A WEAKLY AMPLIFIED
RIDGE OF HIGH PRESSURE WILL BE AFFECTED BY A SERIES OF WAVES
MOVING INTO THE SYSTEM FROM A TROPICAL DISTURBANCE OFF THE BAJA
COAST AND THEN A LONG WAVE TROUGH THAT DROPS ALONG THE WESTERN
COAST. THROUGH THE LATE WEEK A CLOSED LOW WILL DEVELOP NEAR THE
FOUR CORNERS REGION AND SHIFT OUT INTO THE ROCKIES AND INTO THE
PLAINS THROUGH THE WEEKEND. THIS WILL PROLONG THE THREAT OF
SHOWERS AND THUNDERSTORMS. /06/

WILL SPREAD OVER THE AREA WITH ANOTHER AREA OF SHOWERS AND
THUNDERSTORMS DEVELOPING AND MOVING OVER THE FOUR STATE REGION.
STILL LOOKING FOR ANOTHER STRONG NEGATIVE TROUGH TO MOVE ACROSS
WEST TEXAS AND THE SOUTHERN ROCKIES DURING THE DAY MONDAY
PRODUCING ANOTHER ROUND OF STRONG TO POSSIBLY SEVERE THUNDERSTORMS
MONDAY AND MONDAY NIGHT ACROSS THE FOUR STATE REGION. LOCALLY
HEAVY RAINFALL WILL ALSO ACCOMPANY THIS ROUND OF POSSIBLE SEVERE
WEATHER AND RESULT IN ADDITIONAL TWO TO FOUR INCHES OF RAIN. THIS
HEAVY RAINFALL WILL PRODUCE FLASH FLOODING. /06

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTH CENTRAL
ARKANSAS...SOUTHWEST ARKANSAS...NORTH CENTRAL LOUISIANA...
NORTHWEST LOUISIANA...SOUTHEAST OKLAHOMA...EAST TEXAS AND
NORTHEAST TEXAS.

.DAY ONE...TODAY AND TONIGHT...

SHOWERS AND THUNDERSTORMS WILL INCREASE ACROSS THE REGION
TODAY...AHEAD OF A STRONG UPPER LEVEL DISTURBANCE THAT WILL LIFT
NORTHEAST ACROSS THE AREA THIS AFTERNOON AND TONIGHT. DAYTIME
HEATING WILL HELP TO DESTABLIZE THE AIR MASS AHEAD OF THIS
DISTURBANCE...ESPECIALLY OVER DEEP EAST TEXAS...NORTH LOUISIANA
AND SOUTHWEST ARKANSAS...AS STRONG SHEAR AND FORCING ALOFT AHEAD
OF THIS DISTURBANCE SPREADS INTO THE REGION. ISOLATED TO SCATTERED
SEVERE THUNDERSTORMS ARE POSSIBLE...WITH DAMAGING WINDS AND
ISOLATED TORNADOES POSSIBLE. HOWEVER...THE PRIMARY THREAT FROM
THESE THUNDERSTORMS WILL BE LOCALLY HEAVY RAINFALL...WHICH WILL
FALL OVER GROUNDS THAT STILL REMAIN SATURATED FROM EXCESSIVE
RAINFALL THAT FELL EARLIER THIS PAST WEEK. ONE TO THREE INCHES OF
RAIN...WITH ISOLATED HIGHER AMOUNTS...WILL BE POSSIBLE...WHICH
WILL CONTRIBUTE TO INCREASED RUNOFF AND THE POTENTIAL FOR FLASH
FLOODING. THE HEAVY RAIN AND ISOLATED SEVERE THUNDERSTORM THREAT WILL
DIMINISH FROM WEST TO EAST THIS EVENING...ALTHOUGH SCATTERED
SHOWERS AND THUNDERSTORMS WILL PERSIST OVERNIGHT MAINLY OVER DEEP
EAST TEXAS AND NORTH LOUISIANA.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY...

SHOWERS AND THUNDERSTORMS ARE EXPECTED TO INCREASE ONCE AGAIN
MONDAY AFTERNOON AND EVENING OVER THE REGION...AHEAD OF ANOTHER
STRONG UPPER LEVEL DISTURBANCE THAT WILL MOVE INTO THE SOUTHERN
PLAINS. DAYTIME HEATING WILL CONTRIBUTE TO AIR MASS DESTABILIATION
MONDAY AFTERNOON...SUCH THAT SCATTERED SEVERE THUNDERSTORMS
CAPABLE OF PRODUCING DAMAGING WINDS AND ISOLATED TORNADOES WILL BE
POSSIBLE OVER EAST TEXAS...SOUTHWEST ARKANSAS...AND NORTH
LOUISIANA. HOWEVER...THE PRIMARY THREAT WILL AGAIN BE LOCALLY
HEAVY RAINFALL...WITH ADDITIONAL AMOUNTS OF TWO TO IN EXCESS OF FOUR
INCHES LIKELY. THIS WILL RESULT IN RAPID RUNOFF AND ENHANCE THE
POTENTIAL FOR FLASH FLOODING OVER MUCH OF THE REGION.

THE HEAVY RAINFALL THREAT WILL DIMINISH TUESDAY MORNING WITH THE
DEPARTURE OF THIS DISTURBANCE. SCATTERED SHOWERS AND THUNDERSTORMS
WILL REMAIN POSSIBLE WEDNESDAY THROUGH SATURDAY.

.SPOTTER INFORMATION STATEMENT...

ACTIVATION OF EMERGENCY MANAGERS...SKYWARN NETWORKS...AND AMATEUR
RADIO OPERATORS...MAY BE NEEDED THIS AFTERNOON AND TONIGHT FOR THE
POTENTIAL FOR ISOLATED SEVERE THUNDERSTORMS AND FLASH FLOODING...AS
WELL AS RAINFALL REPORTS.
