The radar

The Columbus AFB radar (KGWX), 109 km from the middle of the area, began a volume at 01:34 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 flash flood 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 00:00Z, 1.6 hours before the alert went out and 139 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 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 Apr 16, 3:10 PM CDT, 5 hours 25 minutes earlier.

Area forecast discussion, Apr 16, 3:10 PM CDT, 5 hours 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
310 PM CDT THU APR 16 2015

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT...COUPLED UPPER LEVEL
JET CURRENTLY ALLOWING THE DEVEOLPMENT OF WIDESPREAD SHOWER AND
THUNDERSTORM ACTIVITY FROM SOUTHEAST TEXAS INTO MISSISSIPPI. EXPECT
STORMS TO CONTINUE TO INCREASE IN COVERAGE AND INTENSITY LATE THIS
AFTERNOON AND EVENING. HEAVY RAINFALL WILL BE A CONCERN AND A SEVERE
STORM IS ALSO POSSIBLE. BOTH HAZARDS MAY BE ENHANCED BY WHAT APPEARS
TO BE AN MCV DEVELOPING OVER SOUTHWEST MISSISSIPPI AND A BOUNDARY
EXTENDING FROM NORTHEAST LOUISIANA TO AROUND OXFORD.

THIS ACTIVITY WILL CONTINUE WELL INTO THE EVENING HOURS AS THE JETS
AND MOISTURE REMAIN IN PLACE. LATER TONIGHT AND INTO FRIDAY...WILL
HAVE TO WATCH THE ACTIVITY FURTHER WEST ACROSS TEXAS. STORMS MAY
SURVIVE AND MOVE INTO OUR AREA OR MCVS MAY SURVIVE AND CAUSE
REFORMATION OF STORMS IN THE VERY MOIST AND UNSTABLE ENVIRONMENT.

MODELS PROG A MORE SUBSTANTIAL WAVE TO MOVE ACROSS THE AREA ON
SATURDAY. HIGH PRECIPITABLE WATER VALUES AND MODERATE INSTABILITY
WILL AGAIN LEAD TO SEVERE WEATHER AND HEAVY RAINFALL POTENTIAL PRIMARILY
OVER SOUTHERN PORTIONS OF THE FORECAST AREA. /SW/

SUNDAY INTO SUNDAY NIGHT...AFTER A ACTIVE CONVECTIVE PERIOD...THE
ATMOSPHERE WILL QUICKLY RECOVER AND SETUP A TOTALLY DIFFERENT
THERMODYNAMIC PROFILE FOR SUNDAY. AS DEEP MOISTURE EXITS EAST BY
EARLY SUNDAY...COLDER TEMPS ALOFT (-15C) WILL SPREAD EAST. THIS WILL
COMBINE WITH WARMING LOW LEVELS TO SUPPORT A VERY STEEP LAPSE RATE
ENVIRONMENT. VERTICAL TOTALS OF 29-30C WILL EXIST ALONG WITH H7-H5
LAPSE RATES AROUND 7.5 C/KM. THIS WILL SUPPORT SBCAPE VALUES OF
2500-3000 J/KG. OVERALL...THE ATMOSPHERIC COLUMN WILL BE A BIT DRY
(PW'S 1.2 INCH) WITH A WEAK CAP IN PLACE. THE OVERALL FLOW ALOFT WILL
NOT BE OVERLY FAST BUT CYCLONIC AND CONTAINING A FEW SPOKES OF ENERGY
AND LIFT. GUIDANCE FROM THE EURO/GFS/CANADIAN ARE ALL IN SOLID
AGREEMENT ON THIS SETUP AND EACH INDICATE SOME CONVECTIVE DEVELOPMENT
THROUGH AN EXTENDED WINDOW FROM AT LEAST MIDDAY INTO LATE EVENING.
DUE TO THE CAP AND GENERAL DRYNESS OF THE ATMOSPHERE...EXPECTATIONS
ARE FOR MORE ISO/SCT TYPE STORMS AND OF SUPERCELL MODE. THE VOLATILE
SETUP OF THE ENVIRONMENT WILL SUPPORT ROBUST UPDRAFTS CAPABLE OF
LARGE HAIL AND DAMAGING WINDS. AT THIS TIME...ENOUGH UNCERTAINTY
EXISTS IN EVOLUTION TO NOT GET TOO AGGRESSIVE WITH THE OUTLOOK.
HOWEVER...MULTIPLE INGREDIENTS ARE IN PLACE FOR AT LEAST GOLF BALL
SIZED HAIL AND DAMAGING WINDS. THE POTENTIAL OF TORNADOES IS NON-
ZERO...BUT APPEARS TO LOW AT THIS TIME TO INCLUDE IN THE OUTLOOK. DUE
TO THIS...WILL INTRODUCE AN OUTLOOK FOR SUNDAY WITH HIGHER CONFIDENCE
ACROSS THE NORTHERN 2/3RDS TO RECEIVED SVR STORMS. AN UPDATE TO THE
OUTLOOK MAY BE WARRANTED IF CONFIDENCE INCREASES IN THE POTENTIAL FOR
LARGER HAIL. /CME/

.LONG TERM...MONDAY THROUGH THURSDAY...DRIER AIR WILL FILTER INTO
THE REGION EARLY NEXT WEEK AS HIGH PRESSURE BUILDS INTO THE CWA FROM
THE NORTHWEST. THIS CURRENTLY LOOKS TO LEAD TO A DRY PERIOD FOR MONDAY
AND TUESDAY.

RAIN CHANCES COULD CREEP BACK INTO THE FORECAST FOR THE MIDDLE OF
THE WORK WEEK AS WARM ADVECTION ENSUES AT THE SURFACE. ALOFT... WHILE
OUR FLOW ALOFT BECOMES MORE ZONAL...A SERIES OF UPPER LEVEL
DISTURBANCES SHIFTING EAST THROUGH THE REGION COULD CAUSE SOME
RAIN TO DEVELOP ACROSS FORECAST AREA. /19/SW/

&&

.AVIATION...INCREASING TSRA THIS PM WILL BRING CONDITIONS DOWN TO
IFR/MVFR. PREVAILING MVFR CONDITIONS WILL RETURN AFTER 17/00Z WITH
IFR CIGS/VSBYS AROUND HBG AFTER 17/06Z. VSBYS IN FOG ELSEWHERE WILL
NOT BE AS BIG OF A PROBLEM WITH NO WORSE THAN MVFR EXPECTED./26/
