The episode as NWS JAN wrote it up.
Very dry conditions continued across west-central portions of Mississippi during September. The dry stretch resulted in severe (D2) drought conditions continuing across parts of the Mississippi Delta region despite a few locations receiving above normal rainfall for the month. Crops were put under more stress from the hot and dry conditions. The likely impact will be less crop yields when harvest arrives in early Fall.

AREA FORECAST DISCUSSION...UPDATED AVIATION DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 1145 PM CDT TUE AUG 31 2010 .UPDATE... SHOWER ACTIVITY DIMINISHED EARLIER THIS EVENING IN RESPONSE TO BOUNDARY LAYER STABILIZATION DUE TO SURFACE COOLING. NO ADDITIONAL SHOWERS ARE EXPECTED TONIGHT...WITH SUBSIDENT NORTH TO NORTHEAST FLOW ACROSS THE REGION TO THE WEST OF A MID/UPPER-LEVEL LOW AND TROUGH. THUS...THE MENTION OF SHOWERS HAS BEEN REMOVED FROM THE FORECAST FOR TONIGHT. OTHERWISE...MOSTLY CLEAR TO PARTLY CLOUDY SKIES CONTINUE OVER MUCH OF THE FORECAST AREA. LATER TONIGHT...LOW-LEVEL CLOUD COVERAGE IS EXPECTED TO INCREASE SOMEWHAT...MAINLY ACROSS SOUTHEASTERN AREAS...IN RESPONSE TO LOW-LEVEL MOISTURE ADVECTION. OTHER THAN MINOR ADJUSTMENTS TO HOURLY TEMPERATURE/DEWPOINT FORECASTS PER LATEST OBSERVATIONAL TRENDS...NO ADDITIONAL CHANGES HAVE BEEN MADE TO THE GOING FORECAST. /COHEN/ && .PREV DISCUSSION... /ISSUED 611 PM CDT TUE AUG 31 2010/ PREV UPDATE... WATER VAPOR IMAGERY DEPICTS A CLOSED MID/UPPER-LEVEL CYCLONIC CIRCULATION CENTERED OVER SOUTHWEST ALABAMA...WITH A TROUGH AXIS EXTENDING NORTH-NORTHWESTWARD INTO EAST CENTRAL MISSISSIPPI. SUBSIDENT NORTHERLY TO NORTHEASTERLY FLOW TO THE WEST OF THESE FEATURES IS PREVENTING THE DEVELOPMENT OF ANY PRECIPITATION NORTHEAST OF A LINE FROM GREENWOOD TO MERIDIAN...WHERE MENTION OF SHOWERS HAS BEEN REMOVED FROM THE FORECAST THROUGH EARLY EVENING. TO THE SOUTHWEST OF THIS LINE...AMSU/SSMI TOTAL PRECIPITABLE WATER PRODUCT DEPICTS PWAT VALUES OF AROUND 2 INCHES. IN THIS REGION...RADAR IMAGERY INDICATES ISOLATED SHOWERS PERSISTING. HOWEVER...GIVEN THE SHALLOW NATURE OF THIS ACTIVITY...THUNDERSTORMS ARE NOT EXPECTED AND THUS HAVE BEEN REMOVED FROM THE FORECAST. ADDITIONALLY...SKY COVERAGE WAS INCREASED LATE TONIGHT ACROSS SOUTHEAST MISSISSIPPI...WHERE LOW-LEVEL MOISTURE ADVECTION IS FORECAST TO ENHANCE THE COVERAGE OF LOW STRATUS. HOURLY TEMPERATURE/DEWPOINT FORECASTS WERE ALSO ADJUSTED BASED ON OBSERVATIONAL TRENDS. /COHEN/ PREV DISCUSSION... SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT...DRIER WEATHER IS EXPECTED FOR THE SHORT TERM WITH WARMER AFTERNOON HIGHS AND SLIGHTLY COOLER MORNING LOWS. LATEST WATER VAPOR IMAGERY/RUC ANALYSIS SHOWS THE WEAK UPPER LOW SPINNING OVER THE CENTRAL MISSISSIPPI/ALABAMA STATE LINE NEAR MERIDIAN. THE FEW CLOUDS AND LITTLE RAIN ASSOCIATED WITH THIS FEATURE WAS OVER ALABAMA AND ONLY A BRIEF ISOLATED SHOWER OR TWO WL REMAIN POSSIBLE OVER EAST MISSISSIPPI TODAY. MODELS TAKE THE LOW SOUTH SOUTHWEST TONIGHT WITH LITTLE AFFECT ON OUR WEATHER. DAYTIME HEATING HAS LED TO A FEW SHOWERS DEVELOPING OVER THE SOUTHERN PORTIONS OF THE CWA THAT WERE MOVING WEST. ISOLATED SHOWERS AND PERHAPS A THUNDERSTORM OR TWO WILL BE POSSIBLE THROUGH THE EARLY EVENING HOURS AND MAINLY WEST OF INTERSTATE 55. THE CONVECTIVE ACTIVITY WILL DISSIPATE RAPIDLY AFTER SUNSET. LATEST RUC ANALYSIS STILL HAS A 596DM HIGH CENTERED OVER VIRGINIA WITH A SECOND 596DM HIGH CENTERED OVER CENTRAL TEXAS. BOTH HIGHS ARE EXPECTED TO WEAKEN THROUGH THE SHORT TERM WITH A FLAT RIDGE ALOFT REMAINING OVER THE NORTHERN PORTIONS OF OUR CWA UNTIL FRIDAY. MODELS ARE SLOWER BUT STILL SHOW DRIER AIR SURFACE AND ALOFT FILTERING INTO OUR REGION FROM THE EAST. THE 12Z TUE JAN SOUNDING SHOWED A PW OF 1.97IN. PWS ARE EXPECTED TO DROP TO NEAR AN INCH AND A HALF BY WEDNESDAY AFTERNOON AND NEAR ONE INCH BY THURSDAY AFTERNOON. LOWER 60 DEGREE DEW POINTS WERE BEING OBSERVED OVER OUR NORTHEAST THIS AFTERNOON AND DEW POINTS IN THE 60S WILL GRADUALLY SPREAD WEST ACROSS OUR AREA THROUGH THURSDAY. THERE MAY BE A FEW SHOWERS IN THE SOUTH WEDNESDAY AFTERNOON BUT WL NOT CARRY POPS THURSDAY. NORMAL HIGHS THIS TIME OF THE YEAR RUN IN THE UPPER 80S. AFTERNOON HIGHS WILL BE ABOVE NORMAL AND TOP OUT IN THE LOWER 90S WEDNESDAY AND THE LOW TO MID 90S THURSDAY. NORMAL LOWS RUN IN THE MID TO UPPER 60S. GUIDANCE HAS BEEN A LITTLE TOO COOL LATELY BUT MORE SITES WILL BOTTOM OUT CLOSER TO SEASONAL NORMS IN THE UPPER 60S WEDNESDAY AND THURSDAY MORNINGS. A DEEPENING UPPER LEVEL TROUGH MOVING THROUGH THE NORTHERN PLAINS THURSDAY WILL HELP SEND A COLD FRONT SOUTH THROUGH THE CENTRAL PLAINS. THIS COLD FRONT IS EXPECTED TO MOVE INTO CENTRAL ARKANSAS AND NORTHWEST MISSISSIPPI BY FRIDAY MORNING. WL CARRY MENTION OF POPS AFTER MIDNIGHT THURSDAY NIGHT FOR OUR DELTA REGION. /22/ LONG TERM...FRIDAY THROUGH TUESDAY...THE PRIMARY CONCERNS FOR THIS PERIOD WILL BE THE SOUTHWARD DEVELOPING UPPER TROUGHING FRIDAY THROUGH SUNDAY...THEN UPPER RIDGING COMING BACK FROM THE WEST ON LATE SUNDAY THROUGH TUESDAY. ALSO ITS AFFECT ON LOW RAIN CHANCES AND TEMPS. SOME SHORTWAVE ENERGY MOVING THROUGH THE NORTHERN AND CENTRAL PLAINS AND MISSISSIPPI VALLEY WILL HELP TO PUSH A WEAK SHALLOW FRONT INTO THE REGION ON FRIDAY. THIS FRONT WILL BECOME STATIONARY SOUTH OF THE REGION ON SATURDAY. THE ENSEMBLES CONFIRM THE MAGNITUDE OF THIS UPPER TROUGH BEHIND THE FRONT FOR THIS WEEKEND. THE AXIS OF THE UPPER TROUGH WILL SHIFT EAST OF THE REGION FOR THE LATER PART OF THE WEEKEND. THE STATIONARY FRONT WILL GRADUALLY DISSIPATE AS UPPER RIDGING DEVELOPS FROM THE WEST AS THE UPPER TROUGH MOVES EAST ALONG THE ATLANTIC SEABOARD. THE UPPER RIDGE WILL CONTINUE TO BUILD ACROSS THE REGION FOR MONDAY INTO TUESDAY. AS WE GO INTO FRIDAY THE WEAK FRONT WILL BRING IN A STRIP OF PWATS OF AROUND 2 INCHES. WE WILL GET SOME DRYING FROM THE NORTH WITH PWATS LESS THAN ONE INCH ALONG AND NORTH OF INTERSTATE 20 WITH PWATS AROUND 1.7 INCHES IN THE SOUTH AROUND THE FRONT FOR THIS WEEKEND. AS WE GO INTO LATE SUNDAY INTO MONDAY PWATS WILL RISE AGAIN WITH THE DEVELOPING UPPER RIDGE WITH READINGS AROUND 1.5 INCHES. PWATS WILL DRY FROM THE EAST ON TUESDAY SOME WITH READINGS AROUND 1.2 INCHES. WITH THIS PATTERN ONLY EXPECT ONLY SMALL CHANCES OF RAIN...EXCEPT AROUND THE FRONTAL PASSAGE...THEN RESTRICTED TO THE SOUTH FOR SATURDAY AND MONDAY. AS FAR AS INSTABILITY IS CONCERN WE WILL HAVE MID 20S VERT TOTALS WITH DCAPES AROUND 1000-1500 FOR FRIDAY WITH THE FRONTAL PASSAGE. THIS MAY RESULT IN AN ISOLATED STRONG STORM WITH SOME DOWNBURST POTENTIAL. THE INSTABILITY WILL BE PUSHED TO THE SOUTH FOR SATURDAY THROUGH SUNDAY. WITH THE UPPER RIDGE BUILDING FOR NEXT WEEK EXPECT INSTABILITY TO REBUILD ACROSS THE REGION. DCAPES WILL BE AROUND 1000-2000 ON MONDAY WITH LOW 20S VERTICAL TOTALS. OTHER BEST INSTABILITY INDICES WILL STAY GENERALLY SOUTH AND WEST OF THE REGION FOR EARLY NEXT WEEK. DO NOT EXPECT ANY ORGANIZED ACTIVITY SO WILL KEEP THE HWO CLEAN. AS FAR AS TEMPS ARE CONCERN USED A BLEND OF HIGH END ENSEMBLES...GMOS AND MEX GUIDANCE FOR AFTERNOON HIGHS. WENT CLOSE TO A BLEND OF HIGH END ENSEMBLES...GMOS AND MEX GUIDANCE ON NIGHT TIME LOWS. GUIDANCE WAS A LITTLE COOL FOR THE WEEKEND INTO MONDAY. ESPECIALLY FOR SUNDAY MORNING WITH READINGS IN THE 50S IN THE NORTH. SO WENT CLOSER TO HIGH END ENSEMBLES. HEAT INDICES WILL PUSH TOWARD 100 FOR MAINLY THURSDAY AND TUESDAY. AS FAR AS POPS ARE CONCERN MADE SLIGHT ADJUSTMENTS TO MEX POPS FOR THURSDAY NIGHT THROUGH SATURDAY. MADE SLIGHT ADJUSTMENT FOR LOW POPS IN THE SOUTH FOR MONDAY...THEN WENT WITH THE DRY EURO SOLUTION FOR MONDAY NIGHT THROUGH TUESDAY WITH THE STRONG UPPER RIDGE OVERHEAD. AS FAR AS THE TROPICS GO...MODEL CONSENSUS REMAINS STILL QUIET FOR THE GULF OF MEXICO MUCH OF THE WEEK WITH ALL OF THE BIGGER ACTION CONFINED IN THE ATLANTIC EAST OF 80W LONGITUDE UNTIL LABOR DAY./17/ && .AVIATION...

ALSO...PATCHY FOG RESULTING IN MVFR VISIBILITIES IS EXPECTED DURING THIS TIME...MAINLY ACROSS SOUTHERN MISSISSIPPI AND EAST CENTRAL LOUISIANA. AFTER 01/1400 UTC...GENERALLY VFR CONDITIONS ARE EXPECTED ACROSS THE AREA WITH SOUTHEAST WINDS AT 5 TO 10 KT. ISOLATED SHOWERS AND THUNDERSTORMS ARE EXPECTED ACROSS SOUTHERN MISSISSIPPI AND EAST CENTRAL LOUISIANA FOR WEDNESDAY AFTERNOON. HOWEVER...THE CHANCE FOR THIS ACTIVITY TO IMPACT ANY TAF SITE IS TOO LOW FOR SHOWERS OR STORMS TO BE MENTIONED IN THE TAFS AT THIS TIME. /COHEN/ && .PRELIMINARY POINT TEMPS/POPS...
