The radar

The Columbus AFB radar (KGWX), 53 km from the middle of the area, began a volume at 10:36 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 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

Little Rock, AR (KLZK), launched 00:00Z, 10.6 hours before the alert went out and 130 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.

NWS Memphis, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 4, 4:09 AM CDT, 1 hour 27 minutes earlier.

Area forecast discussion, Jun 4, 4:09 AM CDT, 1 hour 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
409 AM CDT MON JUN 4 2012

.DISCUSSION...

.SHORT-TERM (TODAY THROUGH THURSDAY NIGHT)...

AN ACTIVE WEATHER MORNING CONTINUES ACROSS THE MID SOUTH AS
THUNDERSTORMS HAVE REDEVELOPED ALONG A CONVECTIVE OUTFLOW BOUNDARY
THAT IS STRETCHED FROM NORTHEAST ARKANSAS INTO WEST TENNESSEE.
THESE STORMS HAVE FORMED IN RESPONSE TO A MID LEVEL SHORTWAVE
MOVING INTO THE AREA IN NORTHWEST FLOW ALOFT. TODAYS FORECAST WILL
BE DRIVEN PRIMARILY BY MESOSCALE BOUNDARIES AND CONVECTIVE
INFLUENCES. THE AIRMASS TO THE SOUTH OF THE CURRENT CONVECTIVE
ACTIVITY HAS RECOVERED FROM SUNDAY EVENING THUNDERSTORM ACTIVITY
AND INSTABILITY CONTINUES TO INCREASE IN RESPONSE TO THE
SHORTWAVE. DEWPOINTS ACROSS THESE AREAS REMAIN NEAR 70 DEGREES AND
THIS HAS RESULTED IN CAPE VALUES BETWEEN 1000-1500 J/KG...LI/S
BETWEEN -3C AND -5C...AND MID LEVEL LAPSE RATES NEAR 7.0 C/KM AS
PER LATEST SPC MESOSCALE ANALYSIS. IN ADDITION...THERE HAVE BEEN
RECENT SPOTTER REPORTS OF WIND DAMAGE (POWER POLES DOWN) AND LARGE
HAIL (QUARTER SIZE) FROM NORTHEAST ARKANSAS AND WEST TENNESSEE
WITH THE ONGOING CONVECTIVE ACTIVITY.

CONVECTION SHOULD CONTINUE TO SURGE SOUTH FROM NORTHEAST ARKANSAS
AND SOUTHWEST TENNESSEE INTO FAR NORTH MISSISSIPPI DURING THE
MORNING HOURS AND MAY EVENTUALLY LAY OUT AN OUTFLOW BOUNDARY
ACROSS THE REMAINDER OF EASTERN ARKANSAS AND NORTH MISSISSIPPI BY
EARLY AFTERNOON. SURFACE HEATING THIS MORNING COMBINED WITH NEAR
70 DEWPOINTS SHOULD RESULT IN MODERATE INSTABILITY TO THE SOUTH OF
THE BOUNDARY/CONVECTION. AS THE MID LEVEL SHORTWAVE PIVOTS ACROSS THE
AREA...STORMS SHOULD EITHER CONTINUE OR REDEVELOP ACROSS SOUTHERN
PORTIONS OF THE FORECAST AREA FOR THIS AFTERNOON. LIKELY POPS THIS
MORNING ALONG THE I-40 CORRIDOR AND FAR NORTHERN MISSISSIPPI WILL
TRANSLATE SOUTHWARD INTO THE REMAINDER OF EASTERN ARKANSAS AND
NORTH MISSISSIPPI FOR THE AFTERNOON HOURS. MODERATE
INSTABILITY AHEAD OF THE BOUNDARY/CONVECTION...AN ESTABLISHED COLD
POOL...AND DEEP LAYER SHEAR ON THE ORDER OF 30-40 KTS SHOULD
MAINTAIN A SEVERE THREAT ACROSS THE SOUTHERN HALF OF THE FORECAST
AREA. TEMPERATURES WILL OBVIOUSLY BE MODULATED BY CONVECTIVE
ACTIVITY BUT SHOULD RECOVER TO THE NORTH OF THE MORNING CONVECTION
ACROSS THE NORTHERN HALF OF THE FORECAST AREA. FURTHER
SOUTH...TEMPERATURES WILL LIKELY WARM THIS MORNING BUT MAY BE
KNOCKED DOWN THIS AFTERNOON BY ANY ONGOING CONVECTION.

AS STATED EARLIER...THE AIRMASS ACROSS NORTHERN AREAS MAY RECOVER
BY THIS AFTERNOON BEHIND THE MORNING ACTIVITY. LATEST MODEL
GUIDANCE INDICATES THAT ANOTHER MID LEVEL SHORTWAVE IN NORTHWEST
FLOW ALOFT WILL DROP SOUTH OUT OF THE MIDDLE MISSISSIPPI VALLEY
THIS EVENING AND DRIVE ANOTHER MESOSCALE CONVECTIVE SYSTEM (MCS)
INTO WEST TENNESSEE TONIGHT. THE AIRMASS SHOULD BE UNSTABLE ENOUGH
COMBINED WITH DEEP LAYER SHEAR AROUND 40 KTS TO SUPPORT A DAMAGING
WIND THREAT TONIGHT WITH THE MCS. THIS SHOULD AGAIN FORCE AN
OUTFLOW BOUNDARY SOUTH INTO SOUTHERN PORTIONS OF THE MID SOUTH BY
TUESDAY AFTERNOON WITH ADDITIONAL STORMS LIKELY TO INITIATE OVER
PORTIONS OF EASTERN ARKANSAS AND NORTHERN MISSISSIPPI. ONCE
AGAIN...A STRONG STORM CANNOT BE RULED OUT DUE TO MODERATE
INSTABILITY BUT WEAKER SHEAR ALONG THE CONVECTIVELY REINFORCED
COLD FRONT.

LATEST MODEL GUIDANCE CONTINUES TO SHIFT SOUTH WITH THE FRONT
INCLUDING THE LATEST ECMWF...FORCING IT TOWARDS THE NORTHERN GULF
COAST. THEREFORE HAVE MAINTAINED THE DRY FORECAST OVER THE MID
SOUTH FROM WEDNESDAY THROUGH THE END OF THE WEEK. TEMPERATURES
SHOULD BE SEASONABLE BEHIND THE FRONT WITH LOWER HUMIDITIES
EXPECTED.

JLH

.LONG-TERM (FRIDAY THROUGH SUNDAY)...

00Z GFS/ECMWF LONG TERM MODELS INDICATE HIGH PRESSURE WILL BUILD
INTO THE MID SOUTH FOR FRIDAY AND SATURDAY. SOUTHERLY WINDS AND
LOW LEVEL MOISTURE WILL RETURN TO THE MID SOUTH FROM THE GULF OF
MEXICO BY SUNDAY. THIS WILL RESULT IN CHANCES FOR SHOWERS AND
THUNDERSTORMS RETURNING FOR SUNDAY INTO EARLY NEXT WEEK.

CJC

&&

.AVIATION...

06Z TAF CYCLE

MCS GETTING READY TO EXIT THE REGION LEAVING BEHIND SOME QUICKLY
DIMINISHING STRATIFORM RAIN. EXPECT A FEW QUIET HOURS BEFORE
UPSTREAM DEVELOPMENT OVER NE OK/NW AR/SW MO BEGINS TO MOVE INTO
THE REGION. THE BOUNDARY THAT HAS BEEN LAID DOWN BY THE CURRENT
MCS MOVING THROUGH THE MIDSOUTH MAY ENCOURAGE THE NEXT MCS TO TAKE
A MORE SOUTHERLY TRACK. AS A RESULT CONFIDENCE IN THE LATE NIGHT
TEMPO GROUP FOR TSRAS HAS DECREASED. HAVE DECIDED TO JUST GO WITH
VCTS FOR NOW AT KMEM...KJBR AND KTUP ROUGHLY FROM 04/08Z-04/15Z.
KMKL IS LOCATED IN THE HEART OF THE COLD POOL SO PULLED MENTION OF
THUNDER THERE AFTER 04/07Z. KMKL COULD HAVE SOME LOW CLOUDS/FOG
TOWARD SUNRISE. CONCERNING REDEVELOPMENT MONDAY AFTN...CONFIDENCE
NOT PARTICULARLY HIGH WITH REGARD TO TSRA CHANCES OR TIMING SO
OPTED TO LEAVE OUT MENTION FOR NOW .
