The radar

The Jackson/Brandon,MS radar (KDGX), 34 km from the middle of the area, began a volume at 23:18 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 12:00Z, 11.3 hours before the alert went out and 36 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, Aug 20, 4:13 PM CDT, 2 hours 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
413 PM CDT THU AUG 20 2015

.DISCUSSION...FRONTAL BOUNDARY APPEARS TO BE STALLED VERY CLOSE TO
THE NATCHEZ TRACE CORRIDOR THIS AFTERNOON...FROM COLUMBUS TO NEAR
JACKSON TO MONROE. NORTH OF THIS BOUNDARY...TEMPERATURES HAVE BEEN
RATHER PLEASANT WITH READINGS IN THE 70S AND PLENTY OF CLOUD COVER.
SOUTH OF THE FRONT...READINGS MADE IT INTO THE MID AND UPPER 80S
WITH EVEN SOME LOWER 90S AROUND THE JACKSON AREA. MORNING CLOUD
COVER HAS GIVEN WAY TO A BIT OF SUNSHINE THIS AFTERNOON WHICH HAS
HELPED FUEL SHOWERS AND THUNDERSTORMS IN THE MOIST AIRMASS TO THE
SOUTH OF THE BOUNDARY. THESE STORMS WILL CONTINUE THROUGH THE
REMAINDER OF THE AFTERNOON AND SOME SHOWERS COULD LINGER OVERNIGHT
NEAR THE STALLED FRONT.

THE AFOREMENTIONED FRONT WILL REMAIN STALLED INTO FRIDAY BUT
EVENTUALLY SHIFT BACK NORTH AS A WARM FRONT. SHOWERS AND STORMS WILL
AGAIN BE POSSIBLE ON FRIDAY BUT GIVEN A LACK OF A FOCUSING
MECHANISM...EXPECT THAT CONVECTION WILL BE MORE OF THE DIURNAL/PEAK
HEATING VARIETY IN OUR CONTINUED MOIST/TROPICAL AIRMASS.

COME SATURDAY...THE UPPER LEVEL PATTERN WILL BEGIN TO CHANGE AS THE
CENTER OF THE MID LEVEL RIDGE WILL SHIFT FROM THE NORTH CENTRAL GULF
OF MEXICO BACK INTO CENTRAL TEXAS. THIS WILL LEAVE THE REGION UNDER
NORTHWEST FLOW ALOFT AND DISTURBANCES RIDGING DOWN THIS UPPER LEVEL
FLOW WILL AFFECTED THE ARKLAMISS REGION THROUGH THE WEEKEND. THIS
WILL MEAN CONTINUED RAIN CHANCES THROUGH THE WEEKEND...THOUGH
PERCENTAGES ARE CURRENTLY NOT AS HIGH AS WE HAVE BEEN SEEING THIS
WEEK. WITH THE SOMEWHAT DRIER CONDITIONS...AFTERNOON TEMPERATURES
WILL ONCE AGAIN RISE INTO THE 90S. LOCATIONS THAT HAVE SEEN A LACK
OF RAINFALL THIS WEEK MAY EVEN GET INTO THE MID 90S. LAPSE RATES
SEEM TO GET A LITTLE BETTER WITH VERTICAL TOTALS NEARING 27-28C ON
SATURDAY AND SUNDAY AND LIFTED INDICES ARE FORECAST TO BE AROUND -7
TO -10C. THIS MAY WARRANT OUTLOOKING SOME PORTION OF THE AREA IN THE
HWO IN FUTURE FORECASTS IF TRENDS CONTINUE.

ANOTHER COLD FRONT LOOKS TO DIP DOWN TOWARD THE REGION ON MONDAY.
UNLIKE THIS RECENT FRONT...MODELS DEPICT IT ACTUALLY MAKING ITS WAY
THROUGH THE ENTIRE CWA BY TUESDAY WITH A 1020MB SFC HIGH IN ITS
WAKE. THIS WILL BRING A MUCH COOLER AND DRIER AIRMASS INTO THE
REGION FOR THE MIDDLE OF NEXT WEEK. HIGHS WILL BE IN THE
80S...SEVERAL DEGREES BELOW NORMAL FOR THIS TIME OF YEAR. OVERNIGHT
LOWS COULD ACTUALLY BE IN THE 60S FOR MUCH OF THE CWA...WITH LOWER
60S IN THE NORTH. SOME MODELS INDICATE THAT DEWPOINTS COULD EVEN BE
IN THE 50S...WHICH WOULD BE RATHER NIGHT FOR LATE AUGUST IN THE
SOUTH. SOMETHING TO DEFINITELY LOOK FORWARD TO AFTER THE STRETCH OF
HEAT WE SAW EARLIER THIS MONTH. /28/

&&

.AVIATION...THUNDERSTORMS IMPACTING THE KMEI AND KHBG AREAS THIS
AFTERNOON SO HAVE MADE SOME AMEMDMENTS TO INCLUDE THOSE IMPACTS.
OTHERWISE...SOME LOWER CLOUDS MAY FORM OVERNIGHT AND THEN BREAKUP
AROUND 14Z FRIDAY. /SW/
