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 147 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.

What forecasters said that day

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 Jul 18, 3:24 PM CDT, 20 minutes earlier.

Area forecast discussion, Jul 18, 3:24 PM CDT, 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
324 PM CDT WED JUL 18 2012

.SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT...A PRETTY WET PERIOD
LOOKS ON TAP INTO THE WEEKEND. EXPECT THE CONVECTION TO DIE OFF
DURING THE EVENING HOURS ACROSS THE ARKLAMISS BUT A FEW REMNANT
SHOWERS MAY CONTINUE INTO THE LATE EVENING HOURS. BY THURSDAY THE
UPPER TUTT LOW OVER GEORGIA WILL CONTINUE TO SLOWLY SHIFT TO THE
WEST OVER ALABAMA AND THIS COMBINED WITH ABUNDANT MOISTURE WITH
PWATS WELL ABOVE 2.0 INCHES OVER THE ENTIRE AREA WILL ALLOW
THUNDERSTORMS TO FIRE ONCE AGAIN. THE MOST COVERAGE OF ACTIVITY WILL
CONTINUE TO BE IN THE EAST CLOSER TO THE UPPER LOW...BUT AT LEAST
SCATTERED ACTIVITY WILL BE POSSIBLE OVER THE REMAINDER OF THE AREA.

LITTLE WILL CHANGE ON FRIDAY AS ABUNDANT MOISTURE CONTINUES...BUT
THE GFS DOES INDICATE A LITTLE MORE DEFINED UPPER TROUGHING OVER THE
AREA. EXPECT SCATTERED CONVECTION TO ONCE AGAIN DEVELOP IN THE
AFTERNOON AND CONTINUE INTO THE EVENING HOURS. THE GFS DOES TRY AND
DROP A FRONTAL BOUNDARY INTO THE AREA LATE FRIDAY NIGHT INTO
SATURDAY...WHILE THE ECMWF IS A LITTLE SLOWER AND WEAKER. EITHER WAY
THERE MAY BE LINGERING SHOWERS AND THUNDERSTORMS INTO EARLY SATURDAY.
THERE WILL BE ENOUGH INSTABILITY AND LAPSE RATE FOR AT LEAST ISOLATED
STRONG TO SEVERE STORMS EACH DAY...BUT THE MAIN RISK LOOKS TO BE
VERY HEAVY RAINFALL WITH THE SLOW MOVEMENT OF THE STORMS AND A VERY
MOIST ATMOSPHERE. WILL CONTINUE TO MENTION THIS IN THE HWO. STUCK
PRETTY CLOSE TO GUIDANCE TEMPS/POPS...BUT DID RAISE POPS A TOUCH IN
SOME LOCATIONS IN THE EAST THURSDAY AND FRIDAY. DID NOT MAKE ANY
CHANGES TO THE FORECAST PAST FRIDAY NIGHT...SO WILL ATTACH THE PREVIOUS
LONG TERM BELOW./15/

.LONG TERM...THROUGH NEXT TUESDAY...THE GLOBAL MODELS AND ENSEMBLES
CONTINUE TO GENERALLY AGREE THAT THE CENTER OF THE SUBTROPICAL RIDGE
WILL BE OVER THE PLAINS WHILE AREAS ALONG AND EAST OF THE MS RIVER
WILL BE UNDER A WEAK MEAN TROUGH...WHICH WILL EXTEND DOWN TO THE
ARKLAMISS REGION. THE CENTER OF THE MEAN TROUGH EAST OF THE REGION
WILL BRING A SERIES OF WEAK DISTURBANCES/CONVECTIVE COMPLEXES(MCS)
FROM THE NORTH. SOME OF THE MODELS TRY TO BRING A WEAK BACKDOOR
SURFACE BOUNDARY ACROSS THE NORTHERN PORTION OF THE REGION OVER THE
WEEKEND...WHICH WILL PROVIDE SOME LIMITED LIFT.

DEEP LAYER MOISTURE WILL BE PLENTIFUL DURING THE PERIOD WITH
PRECIPITABLE WATER AROUND AROUND 2 INCHES...WHICH WILL SUPPORT
LOCALLY HEAVY DOWNPOURS. THERE MAY BE SOME STRONG STORM POTENTIAL
FRIDAY INTO SATURDAY PRIMARILY FOR GUSTY WINDS. FOR SUNDAY NIGHT
INTO THE TUESDAY OF NEXT WEEK DAY THE SUBTROPICAL HIGH IS FORECAST
TO INTENSIFY AND EXPAND AS IT CONTINUES TO BUILD WESTWARD AND
SOUTHEASTWARD. BY THE MIDDLE OF THE WEEK IT WILL EXTEND FROM THE
CENTRAL PLAINS THROUGH THE ARKLAMISS INTO THE SOUTHEAST US. WITH THE
PROGRESSION OF THE MEAN RIDGE THIS WILL REDUCE OUR RAIN CHANCES FOR
THE AFTERNOON AND EARLY EVENING HOURS FOR NEXT WEEK.

ONCE AGAIN FOR THE LAST THREE NIGHTS THERE ARE SOME SIGNIFICANT
DIFFERENCES BETWEEN THE WARMER GFS AND SLIGHTLY COOLER 80S ECMWF. WENT
CLOSER TO THE WARMER GFS AND CUT TEMPS SLIGHTLY FROM A BLEND OF
ENSEMBLES...MEX AND GMOS. ON POPS WENT CLOSE TO A BLEND OF GMOS AND
MEX MOS GUIDANCE./17/

&&

.AVIATION...BROKEN CUMULUS FIELD 4-6K FEET THROUGH EARLY EVENING
WILL BE ACCOMPANIED BY SCATTERED/NUMEROUS TSRA SPREAD SWD/SWWD...
SPCLY ALONG AND E OF THE NATCHEZ TRACE BEFORE 03Z AS AN UPPER LEVEL
SHEAR AXIS ROTATES IN FROM THE E. ELSEWHERE...VFR SHOULD DOMINATE
THE AREA THROUGH THURSDAY WITH LOCALIZED MVFR VSBYS LIKELY IN THE
EARLY MORNING HOURS 08-13Z...MAINLY WHERE PREVIOUS SHRA OCCURRED
DURING THE AFTERNOONS. OVERALL SURFACE WINDS WILL BE WLY 4-8KT EACH
DAY...EXCEPT GUSTY AT 35-50KTS WITH THE MOST INTENSE STORMS...BEFORE
DYING OFF TO LESS THAN 5KTS DURING THE OVERNIGHT PERIODS. /40/
