The radar

The Jackson/Brandon,MS radar (KDGX), 45 km from the middle of the area, began a volume at 21:47 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 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, 9.7 hours before the alert went out and 39 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, May 25, 3:49 PM CDT, 55 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
349 PM CDT SUN MAY 25 2008

.DISCUSSION...SHORT TERM(TONIGHT THROUGH MONDAY NIGHT) VERY SLOW-
MOVING ISOLATED SHRA/TSRA ARE THE ORDER OF THE DAY WITH LOCAL
DOWNPOURS AND LIGHTNING STRIKES. DEEP RIDGING AXIS SITUATED ACROSS
THE LOWER MS VALLEY WILL KEEP STORMS VIRTUALLY STATIONARY WITH A
SLIGHT SWD DRIFT POSSIBLE. BEST INSTABILITY POSITIONED ACROSS THE
SWRN HALF OF THE CWFA WHERE MLCAPES/SBCAPES OF 3500/4000J/KG IN
PLACE ALONG WITH 6-6.5C 5-700MB LAPSE RATES. LOCAL WRF AND NAM12 RUNS
DEVELOP STORMS OVER SERN MS SHORTLY AND THEN PROPAGATE THEM WWD THRU
THE HWY 84 CORRIDOR ALONG AN AXIS OF HIGHER 850MB THETA E AIR 350K.
A WEAK SEA BREEZE MOVING THROUGH THE NRN PORTIONS OF COASTAL COUNTIES
SHOULD EDGE UP TO ABOUT HWY 98 BY 6 PM AND HELP SET THINGS IN MOTION
FOR THOSE AREAS.

ON MONDAY...RIDGING AXIS SLIDES WWD TO THE SABINE RIVER VALLEY AND
COULD ALLOW A WEAK TROUGH PASSING BY TO OUR N TO CREATE A SHEAR AXIS/
THERMAL TROUGH SWD ALONG I-55 BY LATE AFTERNOON. AXIS OF 1.65 INCH
PWAT ROTATES CLOCKWISE CENTERED ON THE CWFA. SLIGHTLY WEAKER
CONVECTIVE PARAMETERS SHOULD AGAIN KEEP THE STRONGEST STORMS QUITE
ISOLATED ALTHOUGH WILL MAINTAIN A SCATTERED CATEGORY POP FOR ALL
AREAS. MAX TEMPS FINALLY MADE THE ELUSIVE 90+F AT JUST ABOUT EVERY
LOCATION FOR THE FIRST TIME THIS YEAR. READINGS ONLY BOTTOM TONIGHT AND
MONDAY NIGHT FROM ABOUT 69-73F WHILE HIGHS MONDAY AGAIN 89-93F. NO
BIG ADJUSTMENTS NEEDED TO MAV MOS FOR THIS PERIOD. /40/

LONG TERM(TUESDAY THROUGH SUNDAY)...FOR THE 12Z RUN MEDIUM RANGE AND
ENSEMBLES CONTINUE TO BE IN GENERAL AGREEMENT WITH THE UPPER PATTERN
FOR THE PERIOD. UPPER RIDGE OVER THE REGION WILL MODIFY SOME AS
CANADIAN SHORT WAVE DEVELOPS AN UPPER TROUGH OVER THE EASTERN
US...PUTTING THE THE REGION IN NORTHWEST FLOW ALOFT. THIS WILL SEND A
WEAK FRONT THROUGH THE REGION AT MIDWEEK WITH A PRETTY GOOD CHANCE OF
RAIN. BY FRIDAY THE UPPER TROUGH WILL KICK OUT AS THE UPPER RIDGE
DEVELOPS FROM THE WEST. THE UPPER RIDGE WILL MODIFY SOME FROM THE
NORTH AS A SERIES OF SHORT WAVES MOVES EAST NORTH OF THE REGION.
TODAYS MODELS DO NOT SHOW AS MUCH ENERGY PUSHING TOWARD THE SOUTH FOR
FRIDAY INTO SUNDAY. AS FAR AS POPS ARE CONCERN STICKING WITH CURRENT
FORECAST POPS...WITH THE BEST POPS FOR AROUND THE TIME FOR FRONTAL
PASSAGE AT MIDWEEK. ALSO KEPT CLOSE TO CURRENT FORECAST TEMPS FOR
TUESDAY AND TUESDAY NIGHT. TEMPS FOR TUESDAY THROUGH SUNDAY LOOKED TO
BE ON TRACK. HIGHS WILL RANGE FROM THE LOWER 80S TO LOWER 90S. LOWS
WILL RANGE FROM THE LOWER 60S TO LOWER 70S./17/

PREVIOUS LONG TERM...MONDAY NIGHT THROUGH SUNDAY...COME
MONDAY NIGHT A LARGE UPPER LEVEL HIGH WILL BE CENTERED OVER THE
SOUTHEAST STATES WHILE A SURFACE HIGH IN THE WESTERN ATLANTIC RIDGES
WEST ACROSS THE SOUTHEAST STATES. ONGOING CONVECTION FROM MONDAYS
HEATING WILL GRADUALLY DISSIPATE DURING THE EVENING AFTER SUNSET.
THE EVENING WILL BE WARM AND HUMID INITIALLY BUT SLIGHTLY DRIER AIR
FROM THE EAST WILL FILTER INTO OUR CWFA. THE RESULTING MID 60 DEW
POINTS WILL ALLOW FOR TUESDAY MORNING LOWS CLOSER TO NORMAL. MEDIUM
RANGE MODELS AGREE THAT THE UPPER LEVEL HIGH OVER THE SOUTHEAST
STATES MONDAY WILL WEAKEN AND SHIFT WEST WHILE THE SURFACE HIGH
RIDGING WEST ACROSS THE SOUTHEAST STATES SHIFTS EAST AND WEAKENS
TUESDAY INTO WEDNESDAY. THE SLIGHTLY COOLER AND DRIER AIR FROM THE
EAST WILL LIMIT AFTERNOON SHOWER AND THUNDERSTORM DEVELOPMENT IN THE
SOUTHEAST TUESDAY BUT SCATTERED CONVECTION CAN BE EXPECTED AGAIN IN
THE NORTH TUESDAY AFTERNOON AND EVENING. AN UPPER TROUGH WILL BEGIN
DEEPENING OVER THE EASTERN CONUS TUESDAY AND WEDNESDAY AND HELP SEND
A COLD FRONT TOWARD OUR REGION. THE WEAK COLD FRONT IS STILL
EXPECTED TO DROP THROUGH OUR AREA WEDNESDAY AND BRING THE GREATEST
CHANCE FOR WIDESPREAD RAIN TO OUR CWFA IN THE LONG TERM. THE 1030MB
HIGH NORTH OF THE COLD FRONT WILL WEAKEN AS IT SHIFTS EAST...BUT BE
STRONG ENOUGH TO PUSH THE COLD FRONT INTO THE SOUTHERN PORTION OF
OUR CWFA THURSDAY MORNING. MODELS HINT AT THE FRONT STALLING ALONG
THE GULF COAST BEFORE DISSIPATING AND HOLD POPS ALONG THE HIGHWAY 84
CORRIDOR THROUGH THURSDAY. DRY AIR IN THE WAKE OF THE FRONT WILL
PROVIDE DRY WEATHER FOR THE NORTHERN HALF OF OUR CWFA FROM LATE
THURSDAY MORNING THROUGH SATURDAY. VERY WEAK RETURN FLOW IS EXPECTED
FRIDAY AFTERNOON INTO SATURDAY. BOTH GFS AND ECMWF SHOW ANOTHER
NORTHERN STREAM SHORTWAVE TROUGH SATURDAY MOVING THROUGH THE OHIO
VALLEY. THIS SHORTWAVE AND ASSOCIATED SURFACE LOW WILL SEND ANOTHER
COLD FRONT INTO THE TENNESSEE VALLEY SATURDAY NIGHT. BOTH THE GFS
AND ECMWF SHOW THIS FRONT STALLING JUST NORTH OF OUR CWFA SUNDAY BUT
THE FRONT MAY HELP INCREASE RAIN CHANCES IN OUR NORTHERN ZONES
SUNDAY. /22/.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL OVER TAF SITES THROUGH 03Z
EXCEPT IF AN ISOLATED TSRA DEVELOPS NEARBY. EXPECT ANY ISOLATED
SHRA/TSRA WILL BE DYING OUT BY 03Z THIS EVENING. THEN BROKEN STRATUS
COULD REDEVELOP LATE TONIGHT FOR SRN PORTIONS MAINLY 10-14Z MONDAY.
THERE COULD BE MVFR FOG VISIBILITIES EARLY MONDAY AT JUST ABOUT ANY
LOCATION BUT THESE SHOULD BE VERY TEMPORARY UNLESS RAINFALL OCCURRED
NEAR THE LOCATION./40/

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL MISSISSIPPI...
NORTHEAST LOUISIANA...AND EXTREME SOUTHEAST ARKANSAS.

.DAY ONE...TONIGHT AND MONDAY

ISOLATED STRONG THUNDERSTORMS ARE EXPECTED ACROSS THE AREA THROUGH
THIS EVENING AND AGAIN MONDAY AFTERNOON. SOME OF THESE STORMS MAY
PRODUCE GUSTY WINDS BETWEEN 40 AND 50 MPH...SMALL HAIL...AND FREQUENT
CLOUD TO GROUND LIGHTNING. DUE TO THE SLOW MOTION OF ANY STORMS...LOCAL
TORRENTIAL DOWNPOURS UP TO ONE INCH ARE POSSIBLE WHERE THE STORMS
FORM AND DISSIPATE.

AN UNSTABLE AND MOIST ATMOSPHERE WILL COMBINE WITH THE AFTERNOON HEAT
TO KICK OFF ISOLATED STRONG THUNDERSTORMS. THE FOCUS WILL MAINLY BE
OVER THE SOUTHERN PORTIONS OF THE AREA AS A WEAK SEA BREEZE WORKS
ITS WAY NORTH INTO THE AREA...BUT ANY STORM THAT DEVELOPS MAY BE
STRONG. AN UPPER LEVEL DISTURBANCE WILL APPROACH THE NORTHWESTERN
PORTIONS OF THE AREA THIS EVENING AND THIS MAY KICK OFF A FEW MORE
STORMS IN THE DELTA AREA...SOME OF WHICH MAY BE STRONG.

.DAYS TWO THROUGH SEVEN...MONDAY NIGHT THROUGH SATURDAY

THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.

.SPOTTER CALL TO ACTION STATEMENT...
THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND
EMERGENCY MANAGEMENT PERSONNEL IN SUPPORT OF SEVERE WEATHER
OPERATIONS IS NOT EXPECTED THROUGH NEXT SATURDAY.
