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

Slidell Radar S, LA (KSIL), launched 00:00Z, 0.5 hours before the alert went out and 87 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.

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 10, 3:46 PM CDT, 3 hours 42 minutes earlier.

Area forecast discussion, Jun 10, 3:46 PM CDT, 3 hours 42 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
346 PM CDT FRI JUN 10 2011

...THE HEAT IS RETURNING TO THE REGION...

.UPDATE...HAVE UPDATED THE FORECAST TO REFLECT THE DIMINISHING
COVERAGE OF CONVECTION THIS EVENING. ISOLATED STORMS WILL REMAIN FOR
THE NEXT COUPLE OF HOURS BUT THE RISK OF SEVERE IS DECREASING
RAPIDLY WITH THE APPROACH OF SUNSET. STILL LOOKING FOR THE AREA TO
BE RAIN FREE BY 10 PM.

&&

.DISCUSSION...CONVECTION HAS HAD A LATER START TODAY...BUT THERE
ARE SOME CONVECTIVE CLUSTERS ONGOING ACROSS SOUTHERN AL WHICH ARE
MOVING WESTWARD AND SHOULD INTERACT WITH TOWERING CU ACROSS THE
E-CENTRAL/SE PORTION OF THE CWA LATER THIS AFTERNOON/EVE. CURRENT
POP FORECAST HANDLES THIS WITH LINGERING ACTIVITY GOING UNTIL 8-9
PM. SAME THINKING GOES FOR THE INTENSITY OF THIS ACTIVITY...THERE
REMAINS ENOUGH LAPSE RATE OUT THERE TO SUPPORT SOME STRONG STORMS
WITH A COUPLE SVR STORMS NOT OUT OF THE QUESTION.

LOOK FOR SKIES TO CLEAR WITH ANY CONVECTIVE DEBRIS ALSO GOING AWAY
BY 10 PM. OVERNIGHT LOWS WILL BE SIMILAR TO THIS MORNING AND GUID
WAS PRETTY GOOD. HOWEVER...DID OPT TO LOWER A SITE OR TWO BASED OFF
PERSISTENCE.

SATURDAY WILL BE VERY SIMILAR TO TODAY. THE CONVECTIVE ACTIVITY WILL
BE ISOLATED AND WAIT UNTIL LATER IN THE AFTERNOON TO FIRE AND MAINLY
OCCUR ACROSS THE SE/S PORTION. STEEP LAPSE RATES WILL AGAIN EXIST
AND LIKE TODAY...A FEW STRONG/POSSIBLE SVR STORM COULD OCCUR. SFC
TEMPS WILL BE IN THE MID 90S AND THIS WILL SERVE TO SUPPORT A BIT
MORE INSTABILITY THAN TODAY ALONG WITH MORE INVERTED V SOUNDING
PROFILES.

FOR SUN-WED...THINGS BECOME MORE INTERESTING AND HOTTER. BY LATER IN
THE WEEKEND...WE WILL SEE THE UPPER RIDGE BUILD A BIT TO OUR WEST
AND PLACE US ON THE EASTERN PERIPHERY OF THIS FEATURE. THIS RIDGE
WILL NOT BE AS AMPLIFIED/STRONG AS LAST WEEK...BUT WILL SERVE TO
HEAT THINGS UP IN THE LOWER LEVELS. LOOK FOR TEMPS TO RANGE FROM
95-98...IF NOT A TAD WARMER IF THINGS SET UP JUST RIGHT. LOW LEVEL
TRAJECTORIES WILL HAVE SOME SORT OF NORTHERLY COMPONENT AND THAT
USUALLY LEADS TO 95-100 DEGREES. AT THIS TIME...TWEAKED GUID UP A
BIT...BUT DID NOT GET TOO AGGRESSIVE DUE TO PERSISTENT CONVECTIVE
CHANCES. ON THAT NOTE...THE SUN-WED PERIOD LOOKS TO BE A BIT ACTIVE
IN THE CONVECTIVE DEPARTMENT. AT THIS TIME...POPS ARE ONLY RUNNING
20-30%...BUT WITH ANY STORM...THE POTENTIAL WILL EXIST FOR SVR
WEATHER. THE DEVELOPING NW FLOW TYPICALLY SUPPORTS MORE ACTIVE
SUMMER TYPE STORMS AS LAPSE RATES WILL BE VERY STEEP.
ADDITIONALLY...GUID IS INDICATING A WEAK(BUT PERSISTENT) SFC TROUGH
LINGERING ACROSS A PORTION OF THE CWA NEXT WEEK. THIS WILL SERVE TO
PROVIDE A LOW LEVEL FOCUS AND USUALLY RESULTS IN VERY WARM TEMPS.
THE COMBINATION OF UPPER 90S TEMPS...STEEP LAPSE RATES...SBCAPE 3000
J/KG AND POTENTIALLY SOME MID LEVEL FLOW >20KTS...WILL LEAD TO SVR
STORMS. AT THIS TIME...BEING ON THE EDGE OF THE UPPER RIDGE MAKES IT
A TOUGH FORECAST BECAUSE IT WILL BE A FINE LINE BETWEEN NO STORMS
AND SVR STORMS. EITHER WAY...THE POTENTIAL IS THERE AND WE WILL
BEGIN TO MENTION THIS RISK FOR AT LEAST ISO SVR STORMS SUN-WED IN
THE HWO.
/CME/

&&

.AVIATION...VFR CONDITIONS WILL CONTINUE TO PREVAIL INTO TONIGHT.
EXPECT CONVECTION TO END SHORTLY AFTER SUNSET THIS EVENING...WITH
PATCHY FOG FORMING TOWARD DAY BREAK EARLY SATURDAY MORNING. /19/
