NWS Jackson, MS wrote its last area forecast discussion before the first event at Jul 26, 3:00 PM CST, 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 400 PM CDT MON JUL 26 2010 .SHORT TERM...SHOWERS AND THUNDERSTORMS DEVELOPING IN A MOIST AND UNSTABLE AIRMASS OVER THE REGION HAVE BEEN NUMEROUS THUS FAR ALONG AND SOUTH OF I-20 AND JUST NORTH OF HIGHWAY 82. DEVELOPMENT IN THE NORTHERN AREA HAS BEEN AIDED BY CONVERGENCE NEAR A STALLED BOUNDARY WHILE LIFT FROM AN INCOMING TROPICAL UPPER LOW HAS HELPED SPUR ACTIVITY IN SOUTHERN ZONES. IN THE "GAP" NORTH OF I-20 DEVELOPMENT HAS THUS FAR MAINLY BEEN ISOLATED. HOWEVER...EXPECT THIS AREA TO FILL IN A GOOD DEAL THROUGH THE REST OF THE AFTERNOON AS COLLIDING OUTFLOW BOUNDARIES HELP INDUCE LIFT AND THE INCOMING UPPER LOW FROM THE SOUTH HAS ITS INFLUENCE FELT FURTHER INLAND. 2 TO 2.5 INCH PRECIPITABLE WATER VALUES OVER OUR REGION ARE GIVING STORMS POTENTIAL FOR TORRENTIAL DOWNPOURS AND POCKETS OF CAPE TO 3.5 TO 4.0 KJ/KG DELIVERING SOME INTENSE CELLS AS WELL. GUSTY WIND PRODUCTION THROUGH INSTABILITY AND SUBSEQUENT DOWNDRAFT PRECIPITATION LOADING IS THE MAIN HAZARDOUS WEATHER POTENTIAL WITH THESE STORMS THROUGH EARLY THIS EVENING...ALTHOUGH TORRENTIAL DOWNPOURS AND DANGEROUS LIGHTNING WILL ALSO BE OF CONCERN. IT MAY TAKE CONVECTION LONGER TO COMPLETELY DIE DOWN THIS EVENING THAN IS USUALLY THE CASE FOR SUMMERTIME SHOWERS AND STORMS DUE TO MODEST SOUTHERLY INFLOW OF COPIOUS GULF MOISTURE AND CONTINUING INFLUENCE OF INCOMING TUTT LOW FROM THE SOUTH. AFTER MIDNIGHT PRECIP SHOULD BE LIMITED TO POSSIBLE LINGERING OVERNIGHT ISOLATED SHOWERS AND STORMS IN NORTHWEST ZONES WITH A FEW SHOWERS COMING UP INTO SOUTHERN MS FROM THE COAST BEFORE DIMINISHING. LOWS WILL BE DOWN IN THE LOW TO MID 70S WITH SOME POTENTIAL FOR PATCHY FOG BY DAWN ALONG AND SOUTH OF I-20 IN AREAS WERE HEAVY DOWNPOURS OCCURRED THIS AFTERNOON. THE STREAM OF JUICE NORTH FROM THE GULF OF MEXICO WILL CONTINUE TOMORROW...ALBEIT SOMEWHAT REDUCED IN COMPARISON TO TODAY. THIS DECREASE IN MOISTURE ADVECTION MAY BE MADE UP FOR BY A SYNOPTIC SITUATION SLIGHTLY MORE FAVORABLE FOR CONVECTION CONSIDERING THE TUTT LOW SLIDING TO THE NORTHWEST ON OUR WESTERN FRINGES. RAIN CHANCES WILL AGAIN BE HIGHEST OVER SOUTHERN MS AND ALONG AND WEST OF THE MS RIVER (WHERE THE LINGERING INFLUENCE OF THE SUBTROPICAL RIDGE TO OUR EAST WILL BE LESS). WILL STILL HAVE THE CONCERN FOR HEAVY DOWNPOURS AND SOME STRONG STORMS FOR TOMORROW AFTERNOON...BUT LOWER EXPECTED TEMPERATURES SHOULD REDUCE AVAILABLE INSTABILITY AND REDUCE THE CHANCES OF ANY STORMS BRIEFLY GAINING SEVERE STRENGTH. SPEAKING OF TEMPS...MODEL GUIDANCE DEFINITELY LOOKS A LITTLE COOL WITH UPPER 80S AND LOWER 90S...BUT RAW MODEL OUTPUT ALSO SUGGESTS A LOT OF MID LEVEL CLOUDS DURING THE MORNING AND MIDDAY HOURS TO DELAY WARMING UP. FOR THE LATTER REASON I GENERALLY ACCEPTED THIS COOLER GUIDANCE. .LONG TERM...WEDNESDAY THROUGH MONDAY...LATEST MODEL GUIDANCE STILL SUGGESTS UPPER LEVEL SITUATION BECOMING LESS CONDUCIVE FOR DIURNAL SHOWERS AND THUNDERSTORMS WEDNESDAY THROUGH NEXT FRIDAY AS THE DREADED SUBTROPICAL RIDGE BUILDS BACK FROM THE EAST. HOWEVER...GUIDANCE ALSO DEPICTS THE VERY MOIST AIRMASS BUILDING OVER THE REGION CURRENTLY WILL STICK AROUND WITHOUT ERODING MUCH AT LEAST THROUGH WEDNESDAY AND THURSDAY. THE GFS INSISTS SCATTERED AFTERNOON SHOWERS AND STORMS WILL BUBBLE UP IN THIS AIRMASS...PERHAPS INTO FRIDAY. THE EURO MODEL IS MORE AGGRESSIVELY DRYING THINGS OUT AND HEATING THEM UP THROUGH THIS PERIOD...ALTHOUGH THIS MORNING'S RUN WAS A LITTLE WETTER THAN THE PAST FEW. WEIGHING ALL THE EVIDENCE I ENDED UP RAISING POPS AND LOWERING TEMPS A TAD FOR WEDNESDAY THROUGH FRIDAY...ALTHOUGH A GRADUAL WARMING AND DRYING TREND IS MAINTAINED. THE REST OF THE LONG RANGE PORTION OF THE FORECAST WAS UNCHANGED AND THE RELEVANT DISCUSSION IS BELOW. /BB/ PREV DISCUSSION... /ISSUED 335 AM CDT MON JUL 26 2010/ LONG TERM...WEDNESDAY THROUGH MONDAY...THE REBUILDING OF OUR SUMMER SUBTROPICAL RIDGE WILL BE THE DOMINATING FACTOR FOR THIS PERIOD AS WE HEAD THROUGH THE END OF JULY. INITIALLY WE'LL HAVE A VERY MOIST 2.2 INCH PWAT AIRMASS ACROSS THE REGION TO DEAL WITH ON WEDNESDAY AND DAYTIME INSTABILITY WILL BE GREAT ENOUGH FOR AFTERNOON SHRA/TSRA TO BE MOST NUMEROUS IN WRN PORTIONS OF THE CWFA. EXPECT THERE WILL BE PLENTY OF CLOUD DEBRIS FROM THE PREVIOUS DAY CONVECTION FOR WEDNESDAY AND THURSDAY TO HOLD MAX TEMPS IN THE MIDDLE 90S. HOWEVER...THE STABILIZING UPPER ANTICYCLONE POSITIONED OVER NRN GA WEDNESDAY AT 200MB WILL EXPAND WWD ACROSS THE MID SOUTH THURSDAY AND THEN FINALLY RIGHT OVER MS/AL FRIDAY THROUGH THE WEEKEND. THE VERY JUICY LOW LEVEL AIR RESULTS IN RISING HEAT STRESS LEVELS FOR FRIDAY AND SATURDAY WITH AFTERNOON/EVENING HIGHS PUSHING BACK INTO THE UPPER 90S AND HEAT INDEXES OF 104-109F...SO HEAT ADVISORIES WILL ONCE AGAIN COME INTO PLAY WITH SOME BORDERLINE EXCESSIVE HEAT WARNING CRITERIA POSSIBLE FOR THE HIGHWAY 82 CORRIDOR. BY LATER IN THE WEEKEND...INCREASING SUBSIDENCE SHOULD ALLOW SOME DRYING TO MIX DOWN TO THE RATHER MOIST BOUNDARY LAYER FOR SUNDAY AND MONDAY AFTERNOONS PER LATEST ECMWF. WE WILL NEED TO WATCH TRENDS IN THIS REGARD OR WE'LL BE IN FOR EVEN MORE BUILDING HEAT STRESS. HAVE GENERALLY TRIMMED AFTERNOON POPS FOR ERN HALF OF MS ON WEDNESDAY/THURSDAY AND ACROSS THE BOARD BEYOND THAT. THE EXTENT OF THE RIDGE SUGGESTS THAT WE MAY BE IN FOR A LITTLE LONGER HEAT SPELL AS WE START AUGUST AND THE TROPICS APPEAR RATHER QUIET FOR NOW. MEX MOS AND GFS ENSEMBLE NUMBERS ARE LOCKED IN TO THE HOTTER TREND AND HAVE BEEN CONSISTENT FOR SEVERAL DAYS NOW./40/ && .AVIATION...LOOK FOR REDUCED FLIGHT CATEGORIES THROUGH 00-01Z FOR A FEW SITES THAT WILL GET CONVECTION. TAFS WILL BE UPDATED AS STORMS IMPACT THE SITES. AFTER 01-03Z...VFR CONDITIONS WILL RETURN AND LINGER FOR A GOOD PORTION OF THE EVENING. AFTER 08-10Z...A MOIST LOW LEVEL FLOW WILL ALLOW FOR SOME IFR CONDITIONS TO DEVELOP AFTER 10Z THROUGH 13-14Z. BY 17Z...MORE SCT SHRA/TSRA WILL DEVELOP WITH REDUCED CONDITIONS FOR THE AFTERNOON. /CME/ && .PRELIMINARY POINT TEMPS/POPS...
