What forecasters said that day

The local office's own words before this flash flood 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 flash flood warning went out at May 17, 10:11 PM CDT, 6 hours 9 minutes earlier.

Area forecast discussion, May 17, 10:11 PM CDT, 6 hours 9 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1011 PM CDT SUN MAY 17 2015

.UPDATE...A WEAK MCV MOVING INTO SOUTHWEST MISSISSIPPI LOOKS TO HELP
PROLONG CONVECTION THIS EVENING. THIS MCV IS EXPECTED TO TRACK EAST
NEAR THE HIGHWAY 84 CORRIDOR AND TRIGGER OCCASIONAL SHOWERS AND
THUNDERSTORMS THAT MAY SPREAD ACROSS EAST MISSISSIPPI BEFORE
DISSIPATING. HAVE INCREASED POPS OVER THE CENTRAL AND EASTERN
PORTIONS OF THE AREA THROUGH THE EARLY MORNING HOURS. THE CONVECTION
HAS KNOCKED TEMPERATURES DOWN TO FORECAST LOWS AND MORE OF OUR CWA
SHOULD GET RAIN COOLED OVER THE NEXT SEVERAL HOURS. HAVE LOWERED
FORECAST MINIMUM TEMPERATURES OVER MOST OF THE AREA. /22/

&&

.AVIATION...AN AREA OF TSTMS OVER THE WESTERN PORTIONS OF MS WILL
SPREAD EAST INTO CNTRL MS AND STEADILY WEAKEN. THE ACTIVITY MAY
DISSIPATE BEFORE REACHING GTR-MEI-HBG BUT WL AFFECT TAF SITES ALONG
AND WEST OF I-55. ADDITIONAL STORM DEVELOPMENT MAY AFFECT GLH TOWARD
12Z. OTHERWISE...EXPECT ANOTHER ROUND OF IFR/MVFR STRATUS EARLY
MONDAY MORNING...WHICH WILL LIFT TO VFR LEVELS BY AFTERNOON. SCT TO
NUMEROUS AFTN AND EVNG TSTMS ARE EXPECTED MON.

&&

.PREV DISCUSSION... /ISSUED 347 PM CDT SUN MAY 17 2015/

DISCUSSION...SEMI-ACTIVE WEATHER GOING ON IN THE CWA THIS
AFTERNOON. CONVECTION HAS REFIRED ALONG OUTFLOW FROM OVERNIGHT AR
STORMS OVER THE MS DELTA REGION. THOUGH VERTICAL TOTALS ONLY IN THE
MID 20S...DCAPES IN THIS AREA REMAIN AROUND 1000 J/KG ALONG WITH SOME
0-3KM HELICITY. HAVE SEEN SOME ROTATION IN THOSE ACTIVE STORMS AND
ISSUED A FEW WARNINGS. EXPECT CONVECTION TO CONTINUE INTO THE EVENING
THEN WIND DOWN TOWARD MIDNIGHT.

TRANSITIONING MID LEVEL FLOW PATTERN LOOKS TO KEEP RAIN CHANCES UP
THROUGH TUESDAY. WV AND MODEL DATA INDICATING STRONG MID LEVEL
SYSTEM OVER THE PLAINS LIFTING RAPIDLY OUT NOW TO THE NE INTO THE
PERSISTENT RIDGE OVER THE EAST COAST. THIS WILL HELP BREAK THE RIDGE
DOWN OVER THE EAST ALLOWING THE RIDGE AXIS TO MIGRATE TO THE GULF OF
MEXICO. THIS ADJUSTMENT TO THE RIDGE AXIS WILL PUT THE CWA IN A
WESTERLY FLOW REGIME WITH NUMEROUS SHORTWAVES EMBEDDED IN THE FLOW.
IT WILL ALSO ALLOW A WEAK COLD FRONT TO PUSH THROUGH N MS MONDAY
NIGHT AND HANGING UP OVER CENTRAL SECTIONS TUESDAY.

MODELS INDICATING MORE MCS TYPE DEVELOPMENT TONIGHT OVER AR/LA AFTER
MIDNIGHT THAT LOOKS TO IMPACT NW PORTIONS OF THE CWA. COLD POOL
DRIVEN CONVECTION WILL CONTINUE TO TRAVERSE THE AREA DURING THE DAY
MONDAY. NOT LOOKING FOR ANY WIDESPREAD SEVERE WITH THIS EVENT AS
AMBIENT SHEAR REMAINS WEAK...DCAPES REMAIN LOW AND VERTICAL TOTALS
ONLY AS HIGH AS THE MID 20S. NOT GOING TO RULE OUT A FEW LOCALLY
SEVERE STORMS THOUGH.

ON TUESDAY AS THE FRONT MOVES INTO CENTRAL SECTIONS DURING PEAK
HEATING AND WEAK SHORTWAVES CONTINUE OVERHEAD...EXPECT WIDESPREAD
CONVECTION TO DEVELOP. WHILE SHEAR WILL REMAIN WEAK WITH MID 20S
VERTICAL TOTALS...DCAPES UP AROUND 1200 J/KG AHEAD OF THE BOUNDARY
MAY ALLOW FOR SOME SEVERE WIND POSSIBILITIES WITH THE MORE ROBUST
STORMS. WILL NOT OUTLOOK IN THE HWO AT THE MOMENT DUE TO TEMPORAL
AND SPATIAL UNCERTAINTIES./26/
