NWS Jackson, MS wrote its last area forecast discussion before the first event at Aug 15, 2:30 PM CST, 3 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 330 PM CDT SAT AUG 15 2015 ...WELCOME RAINS WILL COME FOR MANY IN THE REGION OVER THE NEXT FOUR OR FIVE DAYS... .DISCUSSION... SHOWERS AND STORMS CURRENTLY COMING INTO EASTERN PORTIONS OF THE FORECAST AREA ARE IN A BIT GREATER SUPPLY THAN ANTICIPATED...AND THIS MAY BE A GOOD OMEN CONCERNING THE TREND TOWARD A TEMPORARILY WETTER WEATHER PATTERN. AN INVERTED LOW LEVEL TROUGH ADVANCING WEST TOWARD THE HEART OF THE REGION IS TIED CLOSELY TO ONGOING CONVECTION...BUT EXPECT SOME WEAKENING LATE THIS AFTERNOON INTO THIS EVENING AS ACTIVITY APPROACHING THE I-55 CORRIDOR AND HAS TO FIGHT DRIER LOW LEVEL AIR. A FEW OF THE STORMS IN EASTERN MS HAVE BEEN VIGOROUS AND GUSTY BUT SEVERE STORMS ARE STILL NOT LOOKING VERY TERRIBLY LIKELY BECAUSE INSTABILITY AND RELATED MICROBURST POTENTIAL IS RATHER TAME AT PRESENT. TONIGHT EXPECT MOST OF THE SHOWERS AND STORMS TO END IN THE EVENING ALTHOUGH INCREASING GULF MOISTURE TRANSPORT IN SOUTHERN ZONES COULD KEEP SOME SHOWERS GOING THERE THROUGH THE NIGHT. TOMORROW THE INCREASED SOUTHERLY LOW LEVEL FLOW WILL LIKELY BECOME OBVIOUS AS SHOWERS AND STORMS DEVELOP BY MIDDAY IN SOUTHERN ZONES AND WORK STEADILY NORTH THROUGH THE I-20 CORRIDOR IN THE AFTERNOON. IT IS POSSIBLE SOME OF THIS ACTIVITY COULD ADVANCE ALL THE WAY THROUGH NORTHERN ZONES BY LATE IN THE AFTERNOON ALTHOUGH CONFIDENCE IN THE LATTER IS NOT HIGH AT PRESENT. DECENT SOUTHERLY LOW LEVEL WIND VECTORS TOMORROW SHOULD SUPPORT SEMI-ORGANIZED NORTHWARD MOVING LINE SEGMENTS AND THEREFORE SOME GUSTY WINDS CANNOT BE RULED OUT WITH STORMS IN THE AFTERNOON. AT THIS TIME THINKING IS THAT INSTABILITY WILL LIKELY BE NOT HIGH ENOUGH TO THINK THESE WIND GUSTS WILL GET TO SEVERE CRITERIA AND THUS THE HWO WAS LEFT CLEAR. OF COURSE THIS IS SOMETHING WE WILL BE MONITORING FOR THE NEXT FORECAST PACKAGE ISSUANCE. MOST MODEL INDICATIONS ARE THAT MOISTURE AND MOISTURE ADVECTION WILL GET EVEN BETTER FOR MONDAY AS A WEAK UPPER LEVEL TROUGH HANGS OVER THE LOWER MS VALLEY. BLENDED POPS HAVE CONTINUED TO TREND UPWARDS AND WE HAVE FOLLOWED SUIT. THUNDERSTORMS IN AN EXPECTED 2 TO 2.25 INCH PRECIPITABLE WATER AIR MASS WILL FOR CERTAIN BE CAPABLE OF TREMENDOUS DOWNPOURS...BUT THE ANTECEDENT DRY CONDITIONS IN MOST AREAS ARGUE AGAINST THINKING FLOODING WILL BE A BIG WORRY JUST YET. OF COURSE SOME SOUTHERN ZONES HAVE NOT BEEN QUITE AS DRY AND FOR THEM MONDAYS RAIN RISK MIGHT WARRANT MENTION IN THE HWO IF TOMORROW COULD DELIVER ON ITS WET PROMISE. AS ALWAYS...WE WILL MONITOR. /BB/ && .AVIATION...SCATTERED THUNDERSTORMS IN EASTERN MS THIS AFTERNOON WILL BECOME MORE ISOLATED AS THEY ADVANCE TOWARD THE I-20 CORRIDOR THROUGH EARLY EVENING. EXPECT SOME STORMS MIGHT COULD PRODUCE BRIEF MVFR TO IFR CONDITIONS AND GUSTY WINDS...PARTICULARLY ALONG AND EAST OF I-55. LATE TONIGHT SOME BRIEF MVFR LIGHT FOG IS POSSIBLE (ESPECIALLY IN AREAS WHERE RAIN HAS FALLEN). RAIN WILL BE MORE PREVALENT TOMORROW...PARTICULARLY IN THE AFTERNOON AND ALONG AND SOUTH OF I-20. /BB/ && .PREV DISCUSSION... /ISSUED 517 AM CDT SAT AUG 15 2015/ LONG TERM...THE STORY FOR THE MED RANGE/LONG TERM IS THE CHANGE TOWARD A WETTER TYPE PATTERN. THE EURO/GFS CONTINUE TO TREND WETTER AND IN BETTER AGREEMENT WITH HOW EACH EVOLVES THE OVERALL PATTERN AND KEY FEATURES. TEMPS WILL RUN CLOSE TO CLIMO NORMS WITH THE VARIATIONS BEING DRIVEN BY CLOUDS/PRECIP EVENTS AND HOW THE TIMING OF THOSE EFFECTS THE DIURNAL CYCLE. FOR TUE...BETTER THAN AVG RAIN CHANCES WILL CONTINUE...BUT THE SETUP DOESN'T LOOK AS SUPPORTIVE AS MON. THE MAIN REASON IS THE MID LEVELS WILL HAVE MORE OF A S/WV RIDGE TYPE OF FLOW. HOWEVER...HIGH DEEP MOISTURE WILL BE IN PLACE AND THIS WILL OVERCOME SOME OF THE NEGATIVE ELEMENTS. FOR WED/WED NGT...A MUCH MORE SUBSTANTIAL TROUGH WILL DRIVE THE WEATHER. A STOUT MID AUG TROUGH WILL PUSH ACROSS THE CENTRAL/SOUTHERN PLAINS AND ACTUALLY PROGRESS ENOUGH TO HAVE LOWERING HEIGHTS ALONG WITH INCREASING FLOW AND LIFT ALOFT TO BRING MORE OF AN ORGANIZED ROUND OF RAIN/STORMS TO THE REGION. WHILE THE OVERALL CONFIDENCE IN THE EVOLUTION/TIMING OF THIS SYSTEM IS NOT HIGH(5 DAYS OUT)...CONFIDENCE IS ON THE INCREASE DUE TO BETTER AGREEMENT BETWEEN THE GFS/EURO/GEFS/NAEFS. DUE TO THIS...POPS HAVE BEEN INCREASED. AS FOR ANY HAZARDS...WED-WED NGT COULD BE INTERESTING AS STORMS WILL BE INFLUENCED BY MORE SYNOPTIC FORCING AND HAVE MUCH BETTER FLOW TO WORK WITH. THIS PERIOD COULD OFFER MORE OF AN ORGANIZED THREAT AND WE WILL CONTINUE TO WATCH THE EVOLUTION FOR THIS PERIOD. THU-SAT...IN THE WAKE OF THE STOUT UPPER TROUGH...A LINGERING SFC BOUNDARY LOOKS TO REMAIN CLOSE TO THE AREA AND HELP PROVIDE SOME LOW LEVEL FOCUS ALONG WITH KEEPING DECENT DEEP LAYER MOISTURE AROUND. MID LEVEL RIDGING LOOKS TO START BUILDING...BUT ENOUGH INGREDIENTS WILL BE AROUND TO SUPPORT SOME LOWER END POPS INTO NEXT WEEKEND. /CME/ && .PRELIMINARY POINT TEMPS/POPS...

JCThe Columbus AFB radar (KGWX), 137 km away, was scanning. The volume nearest the first event began at 23:47 UTC.
1 thunderstorm wind. Local standard time, as filed.
A couple of trees were blown down, including one at College and Elm streets and also at Moose Lodge and Sweet Home Road. Gutters were also blown off of a home on Martha Drive. This likely came from storm outflow winds.
