The episode as NWS JAN wrote it up.

NWS Jackson, MS wrote its last area forecast discussion before the first event at Jul 25, 2:30 AM CST, 5 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 330 AM CDT SUN JUL 25 2010 SHORT TERM(TODAY THROUGH MONDAY NIGHT)...EARLY MORNING SHRA ALREADY BREAKING OUT ACROSS MANY SECTIONS OF THE CWFA AS REMNANTS OF BONNIE MOVING UP THE MS RIVER AND INTO N CENTRAL LA TODAY...BRINGING SOME MUCH NEEDED RAINFALL. NEAR 80F SURFACE DEWPOINTS OBSERVED WITH THE 1012MB LOW CENTER CROSSING KMSY WITH PWATS OF 2.3+ INCHES AND THIS AMOUNT OF MOISTURE SHOULD STILL EASILY BE CAPABLE OF PRODUCING TROPICAL DOWNPOURS OF LOCALLY HEAVY RAINFALL OF 2 INCHES ALONG/JUST E OF THE TRACK. WILL KEEP THE LOCALIZED FLOODING WORDING IN THE HWO OVER SWRN MS AND PORTIONS OF NERN LA THROUGH TONIGHT ANTICIPATING THE CONCENTRATED MOISTURE. HOPEFULLY...WE CAN PUT A DENT IN THE RAINFALL DEFICITS FOR 2010 WHICH ARE RUNNING 8-15 INCHES IN SOME LOCATIONS W OF I-55. THE BROADER MID-UPPER LEVEL CIRCULATION CENTER(TUTT) IN CENTRAL TX WILL MAINTAIN THE DEEPER SURGE OF MOISTURE UP THE MS RIVER VALLEY THROUGH MONDAY BEFORE SOME DRIER BEGINS ENTERING THE REGION FROM THE E STARTING MONDAY NIGHT. THE CENTRAL TX UPPER CYCLONE ALMOST STALLS OUT TONIGHT BEFORE RESUMING A WLY DRIFT INTO W TX ON MONDAY. BY MONDAY NIGHT...THE SEMI-PERMANENT SUBTROPICAL RIDGE OVER GA/SC BUILDS WWD AGAIN INTO THE TN VALLEY TO START A SLOW DRYING PROCESS AGAIN FOR THE CENTRAL GULF STATES. WILL MAINTAIN SCATTERED/LIKELY POPS ACROSS OUR SWRN 2/3 OF THE CWFA TODAY AND BEGIN TO TAPER OFF POPS MONDAY AFTERNOON FROM E TO W. MAV TEMPS GENERALLY ACCEPTED AS ADDITIONAL CLOUDS/SHRA WILL HOLD DOWN HIGHS SLIGHTLY AND HOLD UP LOWS TO BETWEEN 74-78F./40/ .LONG TERM(TUESDAY THROUGH SUNDAY)...THE PRIMARY WEATHER CONCERNS WILL BE THE TROPICAL MOISTURE COMING FROM THE REMNANTS OF WHAT WAS BONNIE AND OTHER TROPICAL INFLOW FROM THE GULF...FOLLOWED BY THE UPPER RIDGE REGAINING ITS GRIP ON THE REGION. ALSO WITH THE UPPER RIDGE REBUILDING OVER THE REGION THIS MAY BRING ANOTHER ROUND OF EXCESSIVE HEAT ADVISORIES. ONCE THE REMNANTS OF BONNIE MOVES FARTHER INLAND...THE MODELS CONTINUE TO SHOW PLENTY OF TROPICAL MOISTURE FLOWING INTO THE ARKLAMISS REGION. THERE WILL BE A CHANCE OF RAIN FOR TUESDAY THROUGH THURSDAY. ON FRIDAY THROUGH SUNDAY THE UPPER RIDGE WILL REGAINS ITS GRIP ACROSS THE REGION. THE GFS SEEMS TO OVER FORECAST THE CLOUD COVER AND RAIN CHANCES AROUND THE UPPER RIDGE AS IT TRIES TO KEEP MOVING THE RIDGE AROUND AND BRING IN DISTURBANCES IN NORTHWEST FLOW. PREFER TO GO WITH THE CANADIAN...ENSEMBLES AND THE EUROPEAN SOLUTIONS FOR LESS RAIN CHANCES WITH THE UPPER RIDGE. AS THE UPPER RIDGE BUILDS LATER IN THE WEEK OUR CHANCES OF RAIN WILL BEGIN TO GO DOWN FOR THURSDAY THROUGH SUNDAY. THIS WILL CAUSE OUR CONVECTION TO BECOME MORE DIURNAL. THE GFS CONTINUES TO SUGGESTS THERE WILL BE PLENTY OF CLOUDS AROUND...SO LOOKING FOR MORE WARM ADVECTION/TROPICAL ACTIVITY THROUGH TUESDAY AND WEDNESDAY OF NEXT WEEK. SO WITH THIS IN MIND PUT IN DRYER POPS FOR FRIDAY THROUGH SUNDAY. CONTINUED TO KEEP TUESDAY AND WEDNESDAY HIGHS A LITTLE LOWER WITH THE CLOUD COVER AND CHANCES OF RAIN. OTHERWISE WENT WITH A COMBO OF MEX...GMOS AND MEN GUIDANCE. TEMPS WILL GRADUALLY RISE FROM THE LOWER TO MIDDLE 90S TO THE MIDDLE AND UPPER 90S FOR FRIDAY THROUGH SUNDAY AS THE UPPER RIDGE REBUILDS OVER THE REGION. FOR FRIDAY THROUGH SUNDAY HEAT INDEXES WILL PUSH FROM 105 TO NEAR 109...WHICH MAY REQUIRE SOME EXCESSIVE HEAT ADVISORIES IN SOME AREAS. MADE SOME ADJUSTMENTS TO LOWER MEX GUIDANCE POPS THURSDAY THROUGH SUNDAY...BUT MEX POPS LOOKED GENERALLY OK FOR TUESDAY AND WEDNESDAY./17/ .AVIATION...MVFR CLOUDS AND MOISTURE WILL BE SPREADING INTO THE REGION FROM THE SOUTH THIS MORNING. OTHERWISE...VFR CLOUD LAYERS ABOVE 5K FEET WILL DOMINATE THE AREA THROUGH MONDAY. NUMEROUS SHRA AND ISOLATED TSRA WILL RESULT IN IFR CONDITIONS AT TIMES... ESPECIALLY ALONG AND SW OF HIGHWAY 49 BEFORE 02Z. SELY LOW LEVEL WINDS WILL PICK UP TO AROUND 7-10KTS BY THIS AFTERNOON DIMINISHING TONIGHT TO LESS THAN 6KTS...SOME GUSTS OVER SWRN MS COULD REACH 20-25KTS CLOSER TO THE CENTER OF BONNIE.
