Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 4 minutes after it went out.

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

Birmingham, AL (KBMX), launched 12:00Z, 8.9 hours before the alert went out and 145 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, 3:24 PM CDT, 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
324 PM CDT WED JUL 22 2015

.SHORT TERM...
THE MAIN CONVECTION THIS AFTERNOON SET UP ALONG AN OUTFLOW BOUNDARY
FROM EARLY MORNING STORMS ALONG THE TN/MS BORDER. ELSEWHERE...THE
SEA BREEZE WAS RESPONSIBLE FOR TRIGGERING SMALL POP-UP SHOWERS. HEAT
INDICES TODAY ARE JUST AS HIGH AS THEY HAVE BEEN FOR THE PAST WEEK
AND A HALF...DESPITE TEMPERATURES BEING A BIT LOWER THAN WE HAVE
GOTTEN USED TO RECENTLY. WIDESPREAD DEWPOINTS IN THE MID 70S ARE
STILL KEEPING THINGS PRETTY MISERABLE THOUGH.

THE STALLED FRONTAL BOUNDARY ALONG THE TN/MS BORDER WILL CONTINUE TO
REMAIN STATIONARY FOR THE NEXT 24 HOURS. THE SOUTHERN PLAINS RIDGE
WILL AMPLIFY AND MOVE MORE WESTWARD TONIGHT AND THURSDAY LEAVING US
WITH MORE NORTHWESTERLY FLOW...PARTICULARLY OVER THE NORTHEASTERN
HALF OF OUR CWA. THURSDAY CONVECTION WILL THEREFORE BE FOCUSED IN
THIS AREA. A FEW STRONG STORMS MAY BE POSSIBLE DUE TO DIURNAL
DESTABILIZATION PARTICULARLY NEAR THE SURFACE BOUNDARY. IN REGARDS
TO TEMPERATURES...THE HEAT WILL NOT BE AS INTENSE DUE TO THE
INCREASED CONVECTION. COUNTIES AND PARISHES ON THE RIDGE SIDE OF THE
FLOW WILL MOST LIKELY SEE HEAT INDICES ABOVE 100 THOUGH AND QUITE
POSSIBLY 105+. A HEAT ADVISORY MAY BE NEEDED AGAIN TOMORROW FOR THESE
COUNTIES/PARISHES IN THE DELTA AND ALONG THE MS RIVER BUT WILL WAIT
IN ORDER TO INCREASE CONFIDENCE OF CLOUD COVER AND PRECIP EXTENT.
/10/

.LONG TERM...FRIDAY THROUGH EARLY NEXT WEEK...
YESTERDAY IN THE LONG TERM DISCUSSION I WROTE ABOUT THE CONTINUED
INFLUENCE OF THE DREADED UPPER LEVEL OF SUBTROPICAL RIDGE AND ITS
ATTENDANT HEAT...BUT ALSO RECOGNIZED SOME HOPE IN GRADUAL RIDGE
RETROGRESSION BRINGING ABOUT A WELCOME PATTERN CHANGE. IT STILL SEEMS
LIKE BELIEF IN A CHANGE NEXT WEEK IS NOT BLIND FAITH...BUT IT WILL
PROBABLY WAIT UNTIL LATE NEXT WEEK (WHICH IS BEYOND THE OFFICIAL 7
DAY LIMIT OF THIS LONG TERM FORECAST). SO...IN THE BOUNDS OF THE LONG
TERM FORECAST THE SITUATION DOES NOT LOOK GREAT IF YOU ARE LOOKING
FOR A BREAK FROM THIS PROLONGED HEAT WAVE. THE HOTTEST CONDITIONS
SHOULD BE FOCUSED IN WESTERN ZONES OVER THIS PERIOD WHERE DIURNALLY-
DRIVEN SHOWERS AND THUNDERSTORMS WILL BE IN PRETTY SHORT SUPPLY. IN
EASTERN ZONES EXPECT UP TO 30 PERCENT COVERAGE ON MANY AFTERNOONS IN
THE LONG TERM...WHICH WILL OFTEN BE ENOUGH TO COOL MANY PLACES DOWN
BY LATE IN THE AFTERNOON DUE TO THUNDERSTORM OUTFLOW BOUNDARIES.
CONFIDENCE IS STARTING TO GET RATHER HIGH THAT AT LEAST THE WESTERN
HALF OF THE REGION (AT LEAST ALONG AND WEST OF THE BIG RIVER) WILL BE
DEALING WITH CONTINUED HEAT ADVISORIES IN THE LONG TERM. IN
FACT...SOME OF THE ARKLAMISS DELTA MAY HAVE TO BE EVENTUALLY UPGRADED
TO AN EXCESSIVE HEAT WARNING AGAIN AS AIR TEMPS FLIRT HARD WITH THE
CENTURY MARK INTO THIS WEEKEND. FURTHER EAST IT IS POSSIBLE
PERSISTENT HEAT ADVISORIES CAN BE AVOIDED...BUT IT WILL BE A CLOSE
DAY-TO-DAY DECISION IN MANY CASES.

OTHERWISE...AS MENTIONED YESTERDAY...ANTICIPATE SOME POTENTIAL OF
ISOLATED LOCALLY SEVERE STORMS IN THE LONG TERM DUE TO THE
COMBINATION OF HOT TEMPERATURES...HIGH LAPSE RATES...AND MODERATE TO
HIGH INSTABILITY. THERE STILL MAY BE ENOUGH FORCING AND SHEAR UP
NEAR THE GOLDEN TRIANGLE ON FRIDAY TO EVEN BRING ONE LAST GASP OF A
THUNDERSTORM CLUSTER BEFORE BAROCLINICITY PULLS BACK WELL TO THE
NORTHEAST. /BB/

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL TODAY. INCREASED CONVECTION IS EXPECTED
PARTICULARLY FOR KGTR...KMEI...KHBG. FURTHER WEST CONVECTION SHOULD
BE A LITTLE MORE ISOLATED AND MAY IMPACT TAF SITES. THERE WILL BE AN
ISOLATED RISK OF DAMAGING WINDS WITH SOME OF THE STORMS THIS
AFTERNOON INTO THIS EVENING. PATCHY FOG/MIST WILL BE POSSIBLE THROUGH
DAYBREAK RESULTING IN MVFR VIS FOR EASTERN TAF SITES BUT SHOULD LIFT
AFTER DAYBREAK./17/
