The episode as NWS JAN wrote it up.
This system generated early morning thunderstorms across Northern Louisiana, some of these were severe, which then spread a decaying outflow boundary north-eastward across the Mississippi Delta and into North-Central Mississippi before dissipating. This complex of storms and then outflow boundary caused wind damage across portions of far Southeast Arkansas, Northeast Louisiana and portions of Mississippi. Additional isolated severe thunderstorms occurred later in the afternoon before the entire system exited to the northeast.

NWS Jackson, MS wrote its last area forecast discussion before the first event at Apr 25, 5:00 AM CST, 1 hour 50 minutes earlier.
AREA FORECAST DISCUSSION...UPDATE NATIONAL WEATHER SERVICE JACKSON MS 600 AM CDT WED APR 25 2007 .DISCUSSION...LARGE THUNDERSTORM COMPLEX IS KNOCKING ON THE DOOR OF THE FORECAST AREA AND THIS WILL LIKELY SPEED UP THE PROGRESSION OF EVENTS PREDICTED IN THE PREVIOUS FORECAST. MAIN TWEAKS WERE TO INCREASE POPS IN MOST AREAS...GOING UP TO CATEGORICAL IN SPOTS WEST OF THE NATCHEZ TRACE CORRIDOR. ALSO DECREASED PREVIOUSLY FORECASTED TEMPS DOWN TO EXPECTATION OF MUCH COOLER 6Z MAV GUIDANCE WHICH SEEMS TO TAKE INTO ACCOUNT ENHANCED PRECIPITATION POTENTIAL. LATEST ZONES AND GRIDS ARE OUT. /BB/ && .PREVIOUS DISCUSSION...SHORT TERM(TODAY THROUGH THURSDAY) CURRENTLY WATCHING A WELL-DEVELOPING MCS (MESOSCALE CONVECTIVE SYSTEM) HEADING TOWARD THE SABINE RIVER AS A BIG UPPER AIR DISTURBANCE PUSHES TOWARD THE ARKLATEX. THE EVOLUTION OF THIS CONVECTIVE SYSTEM AS IT APPROACHES OUR REGION WILL LIKELY BE PIVOTAL TO HOW THE FORECAST PLAYS OUT OVER THE NEXT 12 HOURS. MAY NEED TO DO AN UPDATE TO THE SHORT TERM FORECAST WITHIN THE NEXT HOUR OR TWO TO CATCH QUICKLY EVOLVING WX TRENDS. THINKING IS THAT DRIER AIR AND CORRESPONDING LESSER INSTABILITY SHOULD CAUSE THE INTENSE MCS TO DEGRADE THIS MORNING AS IT GETS TO THE EDGE OF MY WESTERN ZONES. STILL COULD SEE SOME HEAVY RAIN IN NORTHWEST ZONES AND AN INCREASED RISK OF SEVERE STORMS IN NORTHWEST ZONES TODAY AND HIGHLIGHTED WORDING WAS INCLUDED IN ZONE AND GRID PRODUCTS FOR THOSE SPOTS. COLD STORM OUTFLOW COULD RUN AHEAD OF PRECIP AND COMPLICATE THE FORECAST PICTURE FOR AREAS OF MS LATER TODAY. ALONG AND EAST OF THE FURTHEST ADVANCE OF DEEP OUTFLOW WE CAN ANTICIPATE THE ATMOSPHERE TO DESTABILIZE THROUGH THE AFTERNOON AS DEEP LAYER MOISTURE VALUES TRY TO RECOVER. THIS WILL RESULT IN A WINDOW OF SEVERE THUNDERSTORM POSSIBILITIES FOR MOST AREAS BETWEEN THIS AFTERNOON AND LATER THIS EVENING SINCE THE UPPER DISTURBANCE WILL PROVIDE PLENTY OF ATMOSPHERIC LIFT IN THE PRESENCE OF SUFFICIENT WIND SHEAR. RISKS FOR SEVERE WEATHER WILL PROBABLY HOLD OFF UNTIL TONIGHT IN EASTERN ZONES OF MS...BUT HOW QUICKLY THE RISK WILL SHIFT EAST ACROSS THE AREA THROUGH THE DAY WILL BE STRONGLY CORRELATED TO THE MENTIONED EVOLUTION OF THE CONVECTIVE CLUSTER TO OUR WEST THIS MORNING. AS FOR SEVERE WEATHER POSSIBILITIES...DAMAGING WINDS APPEAR TO BE THE MAIN CONCERN FOR THE AREA TODAY THROUGH TONIGHT...ALTHOUGH SOME HAIL AND ISOLATED TORNADOES CANNOT BE RULED OUT. WOULD BE A LITTLE MORE CONCERNED ABOUT THE TORNADO POTENTIAL IF FORECAST HODOGRAPHS AND SHEAR VECTORS WERE SOMEWHAT BETTER. AS FOR TEMPERATURES TODAY...EXPECT HIGHS AGAIN RANGING FROM 80 TO 85 ALONG AND EAST OF THE INTERSTATE 55 CORRIDOR...BUT PROBABLY HOLDING UNDER 80 WEST OF THIS AREA DUE TO CLOUDS AND PRECIP. MODELS STILL SHOWING DISCREPANCIES WITH HOW QUICKLY PRECIP WILL WORK EAST THROUGH AND OUT OF THE REGION THROUGH THURSDAY...MAINLY BECAUSE OF THE HARD TIME THOSE MODELS ARE HAVING JUDGING HOW THE DRIVING UPPER DISTURBANCE WILL REACT WITH A STRONG UPPER RIDGE CENTER IN THE GULF OF MEXICO. IF THE GFS IS RIGHT...AND IT IS INCREASING LOOKING LIKE IT IS...THEN PRECIP WILL BE ALMOST ENTIRELY EAST OF THE OUTLOOK AREA BY THURSDAY MORNING. PERHAPS A FEW SHOWERS AND THUNDERSTORMS WILL AFFECT EASTERN ZONES OF MS THROUGH MIDDAY THURSDAY BEFORE A COLD FRONT PASSES THROUGH AND SHUTS OFF POTENTIAL...BUT CONFIDENCE IS RELATIVELY HIGH THAT ALL AREAS WILL BE DRY BY THURSDAY AFTERNOON. EXPECT MOSTLY CLEAR TO PARTLY CLOUDY CONDITIONS TO BUILD IN BEHIND THE COLD FRONT FOR THURSDAY WITH SLIGHT COOLER TEMPERATURES (ALTHOUGH PERHAPS NOT QUITE AS COOL AS MAV SUGGESTS). EXPECT HIGHS THURSDAY RANGING FROM THE MID 70S IN THE NORTHWEST TO THE LOW 80S SOUTHEAST. /BB/ LONG TERM(THURSDAY NIGHT THROUGH TUESDAY NIGHT)...CCOLING/DRYING TREND WILL CONTINUE THURSDAY NIGHT WITH WEAK SURFACE RIDGE OVER SERN TX MOVING E ALONG THE GULF COAST. THIS 1019MB HIGH TAKES UP RESIDENCE OVER OUR CWFA ON FRIDAY AS MID AND UPPER LEVEL RIDGING STARTS BUILDING FROM SW CONUS ACROSS THE SRN PLAINS. MEAN OVERALL PATTERN FAVORS A CENTRAL CONUS RIDGE AXIS WITH TROUGHS OFF BOTH COASTS FOR THIS WEEKEND. HOWEVER...WILL CONTINUE MENTION FOR SLIGHT CHANCE POPS LATER SATURDAY AND SATURDAY EVENING AS A MINOR THERMAL TROUGH WORKS THROUGH THE OZARKS TO TN VALLEY REGION. LATEST RUNS OF GFS/ECMWF PRETTY MUCH NOW DISCOUNTING THIS SATURDAY TROUGH AXIS AS SURFACE RIDGE ACTUALLY BECOMES STRONGER TO 1022MB OVER THE LOWER MS VALLEY THROUGH SUNDAY NIGHT. THEN BY MONDAY...THE RIDGE MAINTAINS CONTROL AS IT SLIDES EWD TO THE ATLANTIC COAST BY TUESDAY. WEAK RETURN LOW LEVEL FLOW SHOULD KICK IN BY WEDNESDAY WITH A FEW SHRA/TSRA LATER IN THE DAY. HAVE STAYED CLOSE TO MEX MOS TEMPS IN MOST CASES EXCEPT TO RAISE HIGHS ON A FEW DAYS WHERE A MORE RAPID WARMUP LIKELY DUE TO INCREASED SUNSHINE AND DRY REGIME. HAVE CUT POPS FROM SUNDAY THROUGH TUESDAY NET RESULTS ARE FOLLOWING A BRIEF COOL DOWN ON THURSDAY./40/ && .AVIATION...EXPECT LOTS OF MVFR CONDITIONS AROUND THE REGION THIS MORNING DUE TO LOW CEILINGS WITH SOME POTENTIAL FOR BRIEF IFR CONDITIONS THROUGH 9 AM ACROSS SOUTHEAST MS. STRONG SOUTHERLY FLOW AHEAD OF AN APPROACHING DISTURBANCE WILL PROMOTE SOME WIND SHEAR IN THE LOWER FEW THOUSAND FEET THROUGH MID MORNING...BUT EXPECT LEVELS OF WIND SHEAR TO REMAIN BELOW LLWS CRITERIA. A LARGE THUNDERSTORM CLUSTER BEING DRIVEN BY THIS DISTURBANCE WILL EDGE TOWARD THE MS RIVER THIS MORNING...BUT WILL LIKELY WEAKEN. EXPECT MORE SHOWERS AND THUNDERSTORMS TO REDEVELOP THROUGH THE AFTERNOON ACROSS ALL BUT EASTERN MS...WITH ACTIVITY PROGRESSING EAST INTO EASTERN MS LATER ON THIS EVENING. GUSTY WINDS ARE POSSIBLE WITH THUNDERSTORMS. CONDITIONS WILL CLEAR OUT FROM WEST TO EAST OVER THE REGION LATE TONIGHT THROUGH MIDDAY THURSDAY. /BB/ && .PRELIMINARY POINT TEMPS/POPS...

NORTHEAST LOUISIANA...AND EXTREME SOUTHEAST ARKANSAS .DAY ONE...TODAY AND TONIGHT... ...THUNDERSTORMS... A POTENT UPPER LEVEL DISTURBANCE IS SET TO IMPACT THE ARKLAMISS REGION TODAY THROUGH TONIGHT WHICH WILL BRING THE RISK OF INTENSE THUNDERSTORMS TO THE REGION. ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE THIS MORNING THROUGH LATE THIS AFTERNOON ALONG AND WEST OF A MOREHOUSE LOUISIANA TO GREENWOOD MISSISSIPPI LINE. FURTHER SOUTHEAST...SCATTERED SEVERE THUNDERSTORMS WILL BE POSSIBLE THROUGH EARLY THIS EVENING OVER THE REST OF NORTHWEST MISSISSIPPI AND NORTHEAST LOUISIANA...AND LOCATIONS IN CENTRAL MISSISSIPPI NORTHWEST OF A COLUMBUS TO PRENTISS LINE. FINALLY...LOCATIONS IN EASTERN MISSISSIPPI ALONG AND EAST OF A COLUMBUS TO COLUMBIA LINE WILL HAVE THE POTENTIAL TO EXPERIENCE ISOLATED SEVERE THUNDERSTORMS THIS EVENING. THE PRIMARY RISK WITH THE SEVERE STORMS WILL BE DAMAGING WINDS...ALTHOUGH ISOLATED TORNADOES AND HAIL WILL ALSO BE POSSIBLE. RESIDENTS WEST OF THE NATCHEZ TRACE CORRIDOR ARE URGED TO KEEP UP WITH WEATHER UPDATES THIS MORNING AS AN EVOLVING THUNDERSTORM CLUSTER HEADED TOWARD THE REGION COULD RESULT IN A RAPID DECLINE OF WEATHER CONDITIONS. RISKS OF SEVERE WEATHER ACROSS THE REST OF CENTRAL AND EASTERN MISSISSIPPI WILL BE HIGHEST BETWEEN THIS AFTERNOON AND THIS EVENING. ...FLOODING... HEAVY RAIN WILL BE POSSIBLE ACROSS PORTIONS OF THE ARKLAMISS ALONG AND WEST OF THE NATCHEZ TRACE CORRIDOR THROUGH THIS EVENING AS A POTENT UPPER LEVEL DISTURBANCE AFFECTS THE REGION. EXPECT RAINFALL IN THESE AREAS TO RANGE FROM 1 TO 2 INCHES WITH ISOLATED LOCATIONS RECEIVING 3 INCHES. THESE AMOUNTS OF PRECIPITATION SHOULD NOT CAUSE FLOODING PROBLEMS...BUT MAY RESULT IN MINOR PONDING OF WATER ISSUES. IN ADDITION...THE POTENTIAL FOR WIDESPREAD HEAVY RAINFALL IS A BIT HIGHER OVER PORTIONS OF NORTHWEST MISSISSIPPI...NORTHEAST LOUISIANA AND EXTREME SOUTHEAST ARKANSAS WEST OF A NATCHEZ...TO VICKSBURG...TO GREENWOOD LINE. HERE...THE TRAINING OF THUNDERSTORMS IS POSSIBLE TODAY THROUGH EARLY THIS EVENING WHICH COULD BRING ISOLATED RAINFALL TOTALS UP TO 4 INCHES. THIS WILL BRING A SLIGHT RISK OF FLASH FLOODING PROBLEMS IN THE MOST AFFECTED LOCATIONS. ...NON PRECIPITATION... PATCHY FOG WILL REDUCE VISIBILITIES BELOW ONE MILE AT TIMES THROUGH 9 AM THIS MORNING ACROSS PORTIONS OF SOUTHERN MISSISSIPPI. THIS WILL OCCUR MAINLY SOUTH OF A BROOKHAVEN TO QUITMAN LINE. ANY VISIBILITY REDUCTIONS DOWN BELOW A MILE SHOULD BE ISOLATED AND BRIEF. .DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY... NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME. .SPOTTER CALL TO ACTION STATEMENT... THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND EMERGENCY MANAGEMENT PERSONNEL IN SUPPORT OF SEVERE WEATHER OPERATIONS...MAY BE NEEDED TODAY AND TONIGHT. OTHERWISE...ACTIVATION IS NOT EXPECTED THROUGH NEXT TUESDAY NIGHT MAY 1ST. FOR MORE INFORMATION PLEASE VISIT OUR WEBSITE AT WWW.SRH.NOAA.GOV/JAN.
