The local office's own words before the first event, 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 the first event at Apr 9, 8:46 PM CST, 1 hour 14 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON MS 946 PM CDT THU APR 9 2015 .UPDATE...SHOWERS AND THUNDERSTORMS CONTINUE TO AFFECT PORTIONS OF SOUTHEAST ARKANSAS AND THE MISSISSIPPI DELTA THIS EVENING. STORMS IN THIS REGION...JUST OUTSIDE OF MY CWA...WERE STRONG TO SEVERE THROUGH THE EVENING BUT THIS THREAT SEEMS TO BE WANING AS HAVE THE NUMBER OF WARNINGS TO OUR WEST. STORMS HAVE LOST THE ADVANTAGE OF DAYTIME HEATING AND ARE IN AN ENVIRONMENT THAT APPEARS...PER SPC MESOANALYSIS...TO BE WHERE WEAKER LAPSE RATES EXIST AND HIGHER HEIGHTS ARE PRESENT. WILL KEEP SEVERE THUNDERSTORM WATCH GOING AT LEAST FOR A LITTLE WHILE TO MONITOR TRENDS. BEHIND THE INITIAL CLUSTER OF STORMS IS A THINNER LINE THAT APPEARS TO BE ASSOCIATED WITH THE FRONT. ALL OF THIS WILL CONTINUE TO PUSH INTO THE CWA A LITTLE MORE THROUGH THE NIGHT AND SHOULD BE NEARING THE NATCHEZ TRACE CORRIDOR BY 12Z(ACCORDING TO HI- RES GUIDANCE). WHILE THE SEVERE THREAT WILL DIMINISH...THERE WILL STILL BE SOME POTENTIAL FOR FLOODING AS STORMS CONTINUE TO GENERALLY TRAIN ACROSS THE SAME AREAS. WITH PW VALUES AROUND 1.6-1.7 INCHES IN THE DELTA...THERE COULD BE SOME MINOR FLOODING ISSUES WITH ANY HEAVIER RAIN BAND THAT SETS UP OVER THE AREA. /28/ && .AVIATION...MOST SITES ARE AT VFR THIS EVENING EXCEPT FOR KGLH WHICH IS SEEING MVFR CEILINGS DUE TO SHRA/TSRA. STORMS WILL CONTINUE TO IMPACT TAF SITES THROUGH THE NIGHT AND LOWER CEILINGS AND VIS TO MVFR AND IFR CONDITIONS. A COLD FRONT WILL MOVE THROUGH THE REGION AND SHIFT WINDS OUT OF THE NORTH AROUND 8-10Z FOR DELTA TAF SITES AND AROUND 12-15Z FOR KJAN/KGTR BUT WILL BE LATER INTO FRIDAY FOR KMEI/KHBG. /28/ && .PREV DISCUSSION... /ISSUED 355 PM CDT THU APR 9 2015/ SHORT TERM...(TONIGHT THROUGH SATURDAY NIGHT) LATEST SATELLITE IMAGERY SHOWED A STRONG SHORTWAVE SWINGING THROUGH THE PLAINS. MORNING AREA SOUNDINGS WERE RATHER CAPPED ESP FOR JAN. THIS HAS AFFECTED SHOWER DEVELOPMENT FOR THIS AFTERNOON. SPC ISSUED SOME WATCH BOXES TO THE WEST OF CWA WHERE SOME STRONG TO SEVERE STORMS WERE OCCURRING. FOR THIS AFTERNOON INTO TONIGHT...MODELS SHOWS THAT THE CAP WILL WEAKEN ACROSS MOST OF THE REGION BY THIS EVENING. MODELS SHOWS A COLD FRONT APPROACHING THE REGION FOR THIS EVENING WITH THE STRONG UPPER TROUGH IN TOW. HOWEVER MIDLEVEL HEIGHTS ARE A LITTLE HIGH FOR A CLASSIC SEVERE WEATHER SCENARIO. DO NOT SEE MUCH IN THE WAY OF HEIGHT FALLS FOR TONIGHT. HI RES MODELS SHOWS THAT STRONG TO SEVERE STORMS WILL DEVELOP FROM THE WEST ACROSS THE NORTHWEST DELTA REGION BY EARLY THIS EVENING. THERE COULD BE A FEW STRONG TO POSSIBLY SEVERE STORMS DURING THE LATE AFTERNOON IN THE NORTHWEST PRIOR TO MAIN DEVELOPMENT. SSEO SHOWS THAT THE BEST UPDRAFT SPEED AND HELICITY WILL OCCUR NORTHWEST OF THE CWA. EXPECTING A SQUALL LINE OF STORMS TO PUSH INTO THE NORTHWEST FOR THIS EVENING. THE BEST RISK OF SEVERE WEATHER WILL BE IN THE NORTHWEST... WHERE THE PRIMARY RISK WILL BE DAMAGING WIND GUSTS AND QUARTER SIZED HAIL AS WELL AS A POSSIBLE TORNADO. LOCALIZED FLOODING WILL ALSO BE AN ISSUE IN THE NORTHWEST WHERE PWATS WILL BE AROUND 1.9 INCHES. ALSO CORFIDI VECTORS WILL BE WEAK DURING THE NIGHT. COULD BE LOOKING AT 1 TO 2 INCHES WITH LOCALIZED 3 INCHES POSSIBLE. SO WE WILL HAVE TO CLOSELY MONITOR HEAVY RAINFALL RATES. AS THE LINE ADVANCES FARTHER EAST AND SOUTH IT WILL WEAKEN AS IT ENCOUNTERS HIGHER MIDLEVEL HEIGHTS AND LESS SHEAR. NOT SEEING MUCH IN THE WAY OF HEIGHT FALLS FOR THIS EVENING. AS WE GO FARTHER INTO THE NIGHT THE MAIN FORCING WITH THIS STORM SYSTEM WILL BE NORTHEAST OF THE REGION...WHICH WILL ALSO WEAKEN THE LINE. IT WILL BE ANOTHER MILD NIGHT WITH LOWS IN THE 60S. FOR FRIDAY THROUGH SATURDAY NIGHT... THE MODELS SHOWS THAT THE COLD FRONT WILL PUSH ACROSS THE REGION DURING THE DAY. WITH THE FORCING FAR REMOVED FROM THE REGION THERE WILL BE ENOUGH INSTABILITY FOR A BRIEF WINDOW OF A FEW STRONG TO SEVERE STORMS IN THE SOUTH. THE MODELS EXCEPT FOR THE SLOWER NAM MOVES THE FRONT OUT OF THE REGION BY EARLY AFTERNOON. SO WE WILL KEEP A LIMITED RISK IN THE SOUTH FOR FRIDAY. THE PRIMARY RISK WILL BE QUARTER SIZED HAIL AND 60 MPH GUSTS. FOR FRIDAY NIGHT THE RAINS WILL BE CONFINED TO THE SOUTH WHILE THE NORTH HALF WILL BE RATHER DRY WITH PWATS LESS THAN 0.5 INCH. IT WILL BE A LITTLE COOLER WITH LOWS FROM THE LOWER 50S NORTH TO THE MIDDLE 60S SOUTH. FOR SATURDAY HIGH PRESSURE TO THE NORTH WILL MOVE FROM THE MIDDLE MS VALLEY TO THE ATLANTIC SEABOARD. THIS WILL BRING SOME RETURN FLOW OVER THE REGION ONCE AGAIN. PWATS WILL GRADUALLY INCREASE ACROSS THE REGION RANGING FROM 0.6 NORTHEAST TO THE AROUND 1.5 INCHES SOUTHWEST. MEANWHILE A CLOSED LOW OVER BAJA WILL BE SENDING DISTURBANCES ACROSS THE REGION BY SATURDAY NIGHT. HIGHS FOR SATURDAY WILL BE FROM THE MIDDLE TO UPPER 70S. IT WILL BE ANOTHER COOL NIGHT FOR SATURDAY NIGHT WITH LOWS FROM THE MIDDLE 50S NORTH TO THE LOWER 60S SOUTH. /17/ LONG TERM...(SUNDAY THROUGH NEXT THURSDAY)... FOR SUNDAY SHORTWAVE RIDGING WILL DEVELOP ACROSS THE CWA AS LOW LEVEL MOISTURE RETURN WILL BACK INSTABILITY FOR ANOTHER ROUND OF CONVECTIVE CHANCES ACROSS THE CWA. OUR CHANCES OF RAIN WILL CONTINUE INTO NEXT WEEK. GLOBAL MODELS CONTINUE TO SHOW A LONGWAVE TROUGH TO RIDGE PATTERN OVER THE SOUTHERN CONUS NEXT WEEK THAT MAY RESULT AN UNUSUALLY LONG DURATION OF ACTIVE WEATHER FOR THE ARKLAMISS. IT IS DIFFICULT TO PIN DOWN SPECIFIC PERTURBATIONS IN SOUTHWEST FLOW ALOFT...BUT EXPECT SEVERAL SIGNIFICANT ROUNDS OF CONVECTION TO AFFECT THE AREA AS A SOUTHERN STREAM SHORTWAVE TROUGH LIFTS OUT ACROSS THE PLAINS AND IS REPLACED BY ADDITIONAL SHORTWAVE ENERGY DROPPING INTO THE WESTERN CONUS LONGWAVE TROUGH. THE OP GFS/ECMWF ARE IN STRONG AGREEMENT WITH THIS PATTERN AND THIS GIVES CONFIDENCE FOR INCREASING HEAVY RAINFALL CONCERNS AND PERHAPS SEVERE WEATHER AS WELL. PRECIPITABLE WATER IN THE 1.5 TO 2.0 INCH RANGE WILL BE AVAILABLE THROUGH THE WEEK ALONG WITH STRONG SUBTROPICAL JET SUPPORT...SO THE VERY HEAVY MODEL TOTAL RAINFALL ACCUMULATIONS AND CIPS GUIDANCE HEAVY RAINFALL PROBS ARE NOT UNREASONABLE. AS INDICATED IN PREVIOUS DISCUSSIONS...WILL LIKELY NEED SOME INCLUSION OF HEAVY RAINFALL/SEVERE WEATHER THREATS IN FUTURE HWO PRODUCTS. 17/EC/ && .PRELIMINARY POINT TEMPS/POPS...
