The radar

The Memphis radar (KNQA), 131 km from the middle of the area, began a volume at 17:45 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

Little Rock, AR (KLZK), launched 12:00Z, 5.7 hours before the alert went out and 74 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, Jul 22, 9:40 AM CDT, 3 hours 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
940 AM CDT MON JUL 22 2013

.DISCUSSION...

A SHORT WAVE IS PUSHING INTO NORTH CENTRAL ARKANSAS ATTM. THIS
FEATURE HELPED TO KICK OFF THE MCS THAT IS NOW MOVING THROUGH THE
MEMPHIS METRO AREA WITH HEAVY RAIN...FREQUENT LIGHTNING AND GUSTY
WINDS. THE MCS WILL CONTINUE TO PUSH SE OVER THE NEXT FEW HOURS.
LOOKS LIKE THE BEST CHANCE FOR PRECIP THROUGH EARLY AFTERNOON WILL
BE ACROSS NE MS AS NORTHERN AREAS WILL HAVE BEEN FAIRLY WORKED
OVER FROM THIS MORNINGS ACTIVITY. UPDATE OUT.

.PREV DISCUSSION... /ISSUED 453 AM CDT MON JUL 22 2013/

AN UPPER LEVEL SHORT WAVE EMBEDDED IN A BROAD AND UNSEASONABLY
DEEP UPPER LEVEL TROUGH WAS PUSHING INTO THE MIDSOUTH THIS MORNING
INTERACTING WITH A MOIST AND UNSTABLE ATMOSPHERE. NUMEROUS AREAS
OF THUNDERSTORMS DEVELOPED OVERNIGHT FROM NORTHWEST TN INTO
NORTHERN AR AND SOUTHERN MO. THE THUNDERSTORMS WERE TRACKING EAST
SOUTHEAST AND TRAINING ACROSS SOME LOCATIONS LEADING TO HEAVY
RAINFALL. A REPORT WAS RECEIVED FROM A STORM SPOTTER THAT 3 1/2
INCHES OF RAIN OCCURRED IN BIGGERS AR IN RANDOLPH COUNTY LEADING
TO FLOODING. ADDITIONAL RAINFALL HAS OCCURRED SINCE THE REPORT
WITH DUAL POL PRECIP ESTIMATES FROM THE 88D RADAR INDICATING ABOUT
4 1/2 INCHES OF RAIN IN THAT AREA.

A BROAD AND UNSEASONABLY DEEP UPPER LEVEL TROUGH WILL SET UP OVER
THE EASTERN UNITED STATES THE NEXT FEW DAYS. EMBEDDED SHORT WAVES IN
WEST NORTHWEST FLOW ALOFT WILL AFFECT THE MIDSOUTH AS THEY ENCOUNTER
THE MOIST AND UNSTABLE AIR IN PLACE ACROSS THE REGION. IN
ADDITION...A COLD FRONT WILL PUSH INTO THE AREA WEDNESDAY. TRYING TO
PINPOINT THE TIMING OF THE SHORT WAVES AND THE COLD FRONT MAKES THIS
A DIFFICULT FORECAST...BUT IT DOES LOOK WET..AND VERY WET IN SOME
SPOTS...ALONG WITH THE POSSIBILITY  OF STRONG TO POSSIBLY SEVERE
THUNDERSTORMS OVER THE NEXT FEW DAYS.

AN UPPER LEVEL SHORT WAVE WILL SWING THROUGH THE MIDSOUTH TODAY
CAUSING SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS. A FEW
STRONG THUNDERSTORMS ARE POSSIBLE WITH WIND GUSTS TO NEAR 50
MPH...SMALL HAIL...AND HEAVY RAINFALL THAT MAY CAUSE LOCALIZED FLASH
FLOODING. WILL NEED TO MONITOR FOR A FLASH FLOOD WATCH OVER THE NEXT
FEW DAYS...BUT WILL HOLD OFF FOR NOW SINCE STILL UNCERTAINTY HOW
THE SITUATION WILL EVOLVE. ALSO...FLASH FLOOD VALUES ARE FAIRLY HIGH
WITH THE RECENT DRY WEATHER...AND FOR TODAY CANNOT PINPOINT A
PARTICULAR AREA WHERE WIDESPREAD FLASH FLOODING IS EXPECTED. DID
MENTION HEAVY RAINFALL IN THE ZONES AND GRIDS FOR THIS MORNING
ACROSS PORTIONS OF WEST TN...THE MO BOOTHEEL...AND A PORTION OF
NORTHEAST AR.

THE SHORT WAVE IS FORECAST TO PUSH TO THE SOUTHEAST BY TONIGHT
LEADING TO A TEMPORARY DECREASE IN THE CONVECTION. THE GFS INDICATES
THAT A MESOSCALE CONVECTIVE SYSTEM MAY APPROACH THE MIDSOUTH LATE
TONIGHT FROM THE NORTHWEST AND MOVE INTO THE AREA TUESDAY. THE ECMWF
DOES NOT SHOW THIS FEATURE. FOR NOW...KEPT POPS AT 50 PERCENT FOR
TUESDAY...BUT IF THE GFS IS CORRECT...POPS WILL NEED TO BE RAISED
FOR MUCH OF THE AREA. MID LEVEL LAPSE RATES ARE FORECAST TO DECREASE
LEADING TO GREATER INSTABILITY. THUS MAY SEE A BETTER CHANCE FOR
SEVERE THUNDERSTORMS TUESDAY INTO WEDNESDAY WITH DAMAGING WINDS AND
LARGE HAIL BEING THE MAIN SEVERE WEATHER THREAT. HEAVY RAINFALL WILL
ALSO BE A PRIMARY THREAT AS PRECIPITABLE WATER VALUES CONTINUE NEAR
2 INCHES.

WEDNESDAY LOOKS TO BE A VERY WET DAY WITH A COLD FRONT PUSHING INTO
THE AREA FROM THE NORTH WHILE UPPER LEVEL SHORT WAVES AFFECT THE
AREA IN NORTHWEST FLOW ALOFT. HEAVY RAINFALL ALONG WITH THE THREAT
OF STRONG TO SEVERE THUNDERSTORMS WILL CONTINUE. THE ECMWF IS SLOWER
IN THE MOVEMENT OF THE COLD FRONT THAN THE GFS WITH THE NAM BEING A
NICE COMPROMISE.

DRY WEATHER IS FORECAST TO RETURN THURSDAY AS THE COLD FRONT PUSHES
TO OUR SOUTH. TEMPERATURES WILL BE A LITTLE BELOW NORMAL FOR THIS
TIME OF THE YEAR.

FOR THE LATTER PART OF THE FORECAST...GENERALLY COMPROMISED BETWEEN
THE GFS AND ECMWF LEANING A LITTLE MORE TOWARD THE ECMWF. ANOTHER
UNSEASONABLY DEEP TROUGH AND AN ASSOCIATED COLD FRONT IS FORECAST TO
SWING THROUGH THE MIDSOUTH SATURDAY WITH A CHANCE OF SHOWERS AND
THUNDERSTORMS. POPS WILL NEED TO RAISED IN LATER FORECASTS AS THE
TIMING BECOMES MORE CERTAIN. COOLER AND DRY WEATHER IS EXPECTED
SUNDAY.

.AVIATION...
12Z TAFS

TSRA COMPLEX EAST OF JBR AND 50N OF MEM WAS MOVING SOUTHEAST
AROUND 35 KTS... BUT HAD TAKEN ON A BIT OF A SOUTHWARD PROPAGATION
SINCE 11Z. HAVE BROUGHT FORWARD THE TIMING INTO MEM A BIT. IF THE
TRENDS AT 1130Z HOLD...MEM WOULD BE ON THE SOUTHWEST FLANK OF THE
TSRA COMPLEX...BUT MAY SEE ADDITIONAL WESTWARD DEVELOPMENT ALONG
THE SOUTHWARD SINKING OUTFLOW BOUNDARY.

06Z NAM MODEL CONTINUES TO POINT TOWARD SOME REDEVELOPMENT AROUND
21Z... NEAR AND WEST OF MEM. NOT CONFIDENT ON THIS...GIVEN THE
STRENGTH OF THIS MORNING/S TSRA COMPLEX. BETTER TSRA CHANCES WILL
LIKELY OCCUR TOWARD TUP AFTER 18Z.

LOOKING OUT TO TONIGHT...06Z NAM POINTS TOWARD ADDITIONAL SHRA/TSRA
OVERNIGHT...EMBEDDED IN NORTHWESTERLY FLOW ALOFT. SIGNATURE IS WEAKER
WITH THE PARENT UPPER LEVEL WAVE...MAY GET BY WITH PREDOMINATE
SHRA AFTER 06Z TONIGHT. DAYSHIFT WITH FURTHER EVALUATE.
