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 May 29, 3:50 PM CST, 50 minutes earlier.
AREA FORECAST DISCUSSION...CORRECTED WORDING NATIONAL WEATHER SERVICE JACKSON MS 450 PM CDT FRI MAY 29 2015 .DISCUSSION... TONIGHT THROUGH SUNDAY NIGHT... A VORTEX AND ASSOCIATED BOUNDARY OVER THE ARKLATEX MOVING EAST TOWARD THE ARKLAMISS LATE THIS AFTERNOON WILL INTERACT WITH AN INSTABILITY/MOISTURE AXIS (MLCAPE ~2000 J/KG/PRECIP WATER ~1.6 INCHES) CURRENTLY ALONG AND JUST WEST OF THE MS RIVER. STRONGER FORCING WILL HELP TO ORGANIZE TSTMS...BUT RELATIVELY WEAK FLOW AND EVENTUALLY NOCTURNAL COOLING WILL HELP TO LIMIT SEVERE POTENTIAL. HAVING SAID THAT...A COUPLE OF STRONG TO SEVERE STORMS AND LOCALLY HEAVY RAINFALL COULD BE A CONCERN...MAINLY IN UPPER PORTIONS OF THE ARKLAMISS DELTA REGION THIS EVENING. CURRENT SCATTERED ACTIVITY OVER CENTRAL PORTIONS OF MS WILL DIMINISH WITH LOSS OF DAYTIME HEATING. THESE STORMS OCCASIONALLY PULSE UP ENOUGH TO BECOME STRONG...BUT NOT EXPECTING IT TO REACH SEVERE LEVELS. AS WE GO INTO THE OVERNIGHT AND SATURDAY MORNING...CYCLONIC FLOW MAY HELP TO KEEP SHOWER/TSTM CHANCES GOING IN SPITE OF NOCTURNAL COOLING...ESPECIALLY OVER NW PORTIONS OF THE REGION. A STRONGER SHORTWAVE TROUGH WILL BE DIGGING SOUTHWARD OVER THE ARKLATEX AND WILL SUPPORT ADDITIONAL TSTM DEVELOPMENT FROM SATURDAY AFTERNOON INTO THE EVENING. HAVE INCREASED GUIDANCE POPS SOME OVER SE PORTIONS OF MS SATURDAY AFTN AS BOTH THE GFS/ECMWF PUSH STRONGER MOISTURE CONVERGENCE AND HIGH PRECIPITABLE WATER AIR INTO THE PINE BELT REGION IN ASSOCIATION WITH THE WEAKENING INITIAL WAVE. THEN ACTIVITY IS EXPECTED TO REFOCUS AGAIN FARTHER WEST SATURDAY NIGHT. FOR SUNDAY...GUIDANCE CONSENSUS HAS GOTTEN A LITTLE MORE PROGRESSIVE WITH THE SECOND SHORTWAVE TROUGH AND THIS IS REFLECTED IN THE LATEST FORECAST WITH RAIN CHANCES SHIFTED MORE TO THE EAST. OVERALL...THERE IS STILL SOME CONCERN FOR HEAVY RAINFALL THIS WEEKEND...BUT CONFIDENCE IS REDUCED SOMEWHAT BY THE FLUX IN MODEL TIMING AND LIKELY MESOSCALE INFLUENCES THAT MAKE PICKING OUT A SPECIFIC AREA A TOUGH TASK SO FAR IN ADVANCE. AND THE SEVERE POTENTIAL COULD BE MITIGATED BY CONSIDERABLE CLOUD COVER/PRECIP WHICH WOULD LIMIT DESTABILIZATION. WILL NOT INCLUDE ANY MENTION OF HEAVY RAINFALL OR SEVERE WEATHER IN THE HAZARD PRODUCTS AT THIS POINT. BUT DEPENDING ON HOW ACTIVITY EVOLVES TONIGHT...FOLKS SHOULD MONITOR FOR MORE SPECIFIC HAZARD PRODUCTS SATURDAY MORNING. IN THE LONG TERM...STILL A LOW CONFIDENCE SITUATION GIVEN THAT THE ECMWF/ECENS GUIDANCE IS MUCH MORE PROGRESSIVE THAN THE GFS/GEFS WITH SHORTWAVE ENERGY/CUTOFF LOW PUSHING EAST ACROSS THE GULF COAST STATES EARLY/MID NEXT WEEK. /EC/ LONG TERM...EARLY/MIDDLE OF NEXT WEEK...SOME UNCERTAINTY IS AGAIN CREEPING INTO THE LONG TERM FORECAST THIS SHIFT DUE TO THE LATEST OPERATIONAL EUROPEAN MODEL RUN COMING WITH A MORE PROGRESSIVE TAKE ON THE TROUGH COMING INTO THE LOWER MS VALLEY SUNDAY. PREVIOUS MODEL CONSENSUS WAS STRONGLY IN FAVOR OF THIS TROUGH ENERGY CUTTING OFF OVER TOP OF OUR REGION AND SWIRLING OVERHEAD WELL INTO NEXT WEEK. CONSENSUS STILL FAVORS THIS SOLUTION BUT THE MENTIONED EURO IDEA REDUCES CONFIDENCE AND SUGGESTS SOME CHANCE THAT PROLONGED ABOVE NORMAL RAIN CHANCES MIGHT SHIFT EAST OF OUR REGION FASTER THAN ANTICIPATED. BY MONDAY REPOSITIONING OF THE TROUGH AXIS AND ASSOCIATED AXES OF MOISTURE TRANSPORT AND MOISTURE ADVECTION SHOULD FUEL THE HIGHEST AMOUNT OF DAYTIME THUNDERSTORM PRODUCTION EAST OF THE NATCHEZ TRACE. SOME STORM CHANCES WILL LIKELY PERSIST BACK WEST INTO THE ARKLAMISS DELTA AS WELL ON MONDAY...BUT THIS PROSPECT COULD POTENTIALLY CHANGE IF THE EURO IS CORRECT WITH ITS LATEST PROGRESSIVE TAKE OF UPPER LEVEL TROUGH MOVEMENT. THE FORECAST FOR TUESDAY THROUGH THURSDAY COULD BE IMPACTED A GREAT DEAL IF THIS TROUGH IS INDEED PROGRESSIVE AND CUTS OFF FROM THE JET- LEVEL STEERING CURRENTS TO OUR EAST. IN THAT CASE AFTERNOON SHOWER AND STORM CHANCES COULD BE MUCH MORE LIMITED THAN WHAT THE FORECAST CURRENTLY REPRESENTS (ESPECIALLY WEST OF I-55) WHILE DAYTIME TEMPERATURES MAY TREND WARMER. HOWEVER...AS MENTIONED PREVIOUSLY...THE CONSENSUS AND CONSISTENT MODEL SOLUTION OF TROUGH ENERGY CUTTING OFF OVERHEAD STILL ARGUES FOR ABOVE NORMAL RAIN CHANCES TO CONTINUE WELL INTO THE WEEK WITH CLOUDS AND PRECIP KEEPING TEMPS DOWN A FEW DEGREES. HOPEFULLY BY THIS TIME TOMORROW MODEL CONSENSUS WILL STRENGTHEN REGARDING SOLUTIONS FOR OUR REGION OVER THIS TIME FRAME. /BB/ && .AVIATION...VFR CONDITIONS ONGOING THIS AFTERNOON. SCATTERED TO ISOLATED SHOWERS AND STORMS ARE MOVING SOUTH TO NORTH AND COULD AFFECT A TAF SITE THROUGH THE AFTERNOON. ANOTHER LINE OF STORMS MOVING IN FROM THE WEST COULD AFFECT WESTERN TAF SITES THROUGH EARLY EVENING BUT CONFIDENCE IN THIS IS NOT HIGH. WITH ANY THUNDERSTORM THERE COULD BE CEILING AND VIS RESTRICTIONS POSSIBLE TO MVFR/IFR CATEGORIES. STRATUS AND IFR CEILINGS WILL BE POSSIBLE AGAIN TONIGHT. /28/ && .PRELIMINARY POINT TEMPS/POPS...
