The radar

The Jackson/Brandon,MS radar (KDGX), 60 km from the middle of the area, began a volume at 20:48 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

Jackson, MS (KJAN), launched 12:00Z, 8.7 hours before the alert went out and 53 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 10, 3:15 PM CDT, 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
315 PM CDT THU JUL 10 2014

.SHORT TERM...
MORNING MCS HAS PUSHED E INTO AL. DIFFUSE OUTFLOW BOUNDARY EXTENDS
WNW FROM THIS COMPLEX FROM NEAR KHBG TO KTVR/KMLU. SCT TSRA HAS BEEN
REDEVELOPING ALONG THIS BOUNDARY. ADDITIONALLY...LARGER MORE
ORGANIZED CONVECTIVE COMPLEX CONTINUES TO DROP ESE INTO CENTRAL AR.
EXTRAPOLATION BRINGS THIS COMPLEX INTO NW SECTIONS OF OUR AREA 22Z-
00Z...AND ADDITIONAL DEVELOPMENT IS OCCURRING IN MOIST/UNSTABLE
AIRMASS AHEAD OF THIS FEATURE. HENCE HAVE CONCENTRATED HIGHEST POPS
FOR THE EVENING IN W AND S SECTIONS. EXPECT COVERAGE OF CONVECTION TO
GRADUALLY WANE AFTER SUNSET...BUT GIVEN PERSISTENCE OFF LAST COUPLE
OF NIGHTS WILL KEEP SLIGHT CHANCE IN THE S AND W ALL NIGHT.

FOR FRI...DRIER AIR CURRENTLY OVER MID SOUTH PER LATEST BLENDED TPW
PRODUCT PUSHES INTO NORTHERN AND EASTERN AREAS...BUT MODELS SHOW
HIGHER MOISTURE REMAINS OVER WESTERN/SOUTHERN AREAS WITH PW VALUES
NEAR 2 INCHES. HENCE WILL TAILOR POPS WITH HIGHEST IN SW FOR DIURNAL
CONVECTION FRI AFTERNOON. BY SATURDAY DRIER AIR MAKES A BIGGER PUSH
ACROSS THE ENTIRE AREA...WILL LIMIT SLIGHT CHANCE POPS TO FAR
SOUTHERN AREAS.

AS FAR AS TEMPERATURES...GFS MOS SEEMS TO HAVE TOO LARGE OF DIURNAL
RANGES GIVEN THE AMOUNT OF RAIN THAT HAS FALLEN IN RECENT WEEKS. HAVE
TRENDED TEMPS CLOSER TO ECMWF/NAM BLEND.                     /08/

.LONG TERM...
FOCUS OF LONG TERM LOOKS AS THOUGH IT WILL BE ON A DEVELOPING TROUGH
OVER GREAT LAKES WHICH SHOULD PUSH AN UNSEASONABLY STRONG COOL FRONT
TOWARD OUR AREA NEXT WEEK. PREVIOUS LONG TERM DISCUSSES THIS SETUP
AND FOLLOWS.

HEADING INTO NEXT WEEK...THE UPPER RIDGING GIVES WAY TO A RATHER LARGE
UPPER TROUGH THAT WILL BE LOCATED ACROSS THE GREAT LAKES REGION. THIS
WILL TAKE UP RESIDENCE THROUGH THE REST OF THE PERIOD. A SERIES OF
WAVES WILL MOVE THROUGH THE BASE OF THE TROUGH...ONE OF WHICH WILL
SEND A COLD FRONT IN OUR DIRECTION. THIS FRONT WILL MOVE INTO THE
ARKLAMISS TUESDAY INTO WEDNESDAY. BOTH THE GFS AND THE ECMWF BRING
THE FRONT ALL THE WAY THROUGH THE CWA BY EARLY THURSDAY. GIVEN PLENTY
OF MOISTURE AHEAD OF THE FRONT...WE WILL SEE A BETTER CHANCE FOR
SHOWERS AND STORMS COME TUESDAY AND WEDNESDAY. BEHIND THE FRONT. ALSO
BEHIND THE FRONT...COOLER AIR WILL MOVE IN WITH SOME BELOW NORMAL
TEMPERATURES POSSIBLE. /08/28/

&&

.AVIATION...
MORNING CONVECTION HAS MOVED INTO AL...BUT NEW
DEVELOPMENT HAS BEGUN ON OUTFLOW FROM JUST SOUTH OF JAN TO MLU. A
PEPPERING OF SHOWERS HAS ALSO DEVELOPED OVER SE AR. WILL JUST HAVE
VICINITY TS POSSIBILITIES UP UNTIL 02Z WITH VFR CONDITIONS AND LIGHT
MIST DEVLOPING THERAFTER. MVFR VISIBILITIES IN MIST WILL DEVELOP
FROM 10 TO 14Z...OTHERWISE VFR CONDITIONS WILL PREVAIL
THEREAFTER./26/
