The episode as NWS JAN wrote it up.
Scattered storms developed across the Delta during the midday hours. One storm became strong and produced some wind damage just north of Greenville.
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 Aug 8, 9:15 AM CST, 2 hours 25 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON MS 1015 AM CDT FRI AUG 8 2014 .UPDATE... UPPED THE POPS IN THE NORTH FOR THIS MORNING AND EARLY THIS AFTERNOON. THIS WILL BE THE MAIN FOCUS FOR STORMS TODAY. A JUMBLED LINE OF STORMS IS ALREADY STARTING TO FORM IN SOUTHEAST ARKANSAS AND MOVING SOUTHEAST TOWARDS OUR AREA. THE MICROBURST CHECKLIST SHOWED A LIKELY CHANCE FOR WET MICROBURSTS TODAY SO ANY STORMS THAT FORM OR MOVE INTO THE CWA WILL NEED TO BE WATCHED CAREFULLY. HEAT INDICES WILL ALSO BE ELEVATED THIS AFTERNOON AND RANGE FROM 101 TO 105 IN PEAK HEATING TODAY. /10/ && .AVIATION... A GOOD SCATTERING OF SHOWERS AND THUNDERSTORMS CAN BE EXPECTED THIS AFTERNOON WITH MAINLY VCTS CARRIED IN TAFS. CONVECTION WILL END BY 09/03Z WITH MVFR VISIBILITIES DEVELOPING AT MOST LOCATIONS BY 09/06Z...ESPECIALLY AT SPOTS THAT GET RAIN TODAY. VFR CONDITIONS WILL RETURN AFTER 09/13Z./26/ && .PREV DISCUSSION... /ISSUED 438 AM CDT FRI AUG 8 2014/ DISCUSSION... TODAY THROUGH SATURDAY NIGHT... WEAK SHORT WAVE TROUGH PASSING THROUGH THE SUBTROPICAL RIDGE ACROSS THE REGION WILL BE THE IMPETUS FOR DECENT CONVECTIVE COVERAGE TODAY...BUT MAINLY NORTH OF INTERSTATE TWENTY. MODELS HAVE HAD A TOUGH TIME THE PAST FEW DAYS DIAGNOSING AND PREDICTING THE UNFOLDING OF EVENTS AT THE INTERFACE OF THE SUBTROPICAL RIDGE AND THE SOUTHERN FRINGE OF WESTERLIES TO THE NORTH...AND SOLUTIONS OFFERED TODAY APPEAR NO DIFFERENT. THROUGH THE SHORT TERM PERIOD WILL STAY GROUNDED IN THE NOTION THAT MAIN ATMOSPHERIC LIFTING CHANNEL WILL REMAIN JUST NORTH AND NORTHEAST OF THE CWA WITH SUBSIDENT EFFECTS (AND ASSOCIATED HEAT) OF SUBTROPICAL RIDGING ALOFT MOST EVIDENT ACROSS THE SOUTHERN HALF OF ZONES. SPECIFICALLY FOR TODAY...THE MENTIONED TROUGH WILL PROMOTE DECENT LIFT CONSIDERING THE IN SITU SOUTHERN TIER SUBTROPICAL RIDGE BUT LOW LEVEL CONVERGENCE AND FORCING WILL NOT BE MODEST AT BEST. FOR THAT REASON SHOWERS AND STORMS OF LOOSE ORGANIZATION SHOULD RIDE ACROSS NORTHERN ZONES BUT HAVE SERIOUS TROUBLE EXTENDING IN MORE THAN HAPHAZARD FASHION ACROSS CENTRAL AND SOUTHERN ZONES. SEVERAL STRONG STORMS ARE EXPECTED BUT SHEAR/INSTABILITY COMBINATIONS ARE NOT GREAT AND LAPSE RATES NOT INDICATIVE OF MORE THAN A LOW-END MICROBURST RISK. CONVECTION IN THE NORTH COULD LIMIT HIGHS TO THE LOW 90S BUT ELSEWHERE ANTICIPATE MID 90S AND HIGH HUMIDITY. AS IS TYPICAL A MAJORITY OF CONVECTION SHOULD DIE OFF IN THE EVENING. HOWEVER...A FRONTAL ZONE SAGGING INTO THE OZARKS TONIGHT WILL HELP SPUR A HOT AND MOIST SOUTHWESTERLY LOW LEVEL JET IN THE NEIGHBORHOOD OF THE ARKLAMISS DELTA LATE. DESPITE LACK OF UPPER SUPPORT THIS A PLAUSIBLE INGREDIENT TO FUEL A SMALL THUNDERSTORM COMPLEX MOVING INTO THE ARKLAMISS DELTA BEFORE DAWN...AS THE EURO MODEL AND SOME OTHER HIRES MODELS SUGGEST. I TRENDED TOWARD THIS SCENARIO IN THE OFFICIAL FORECAST BUT STILL AM NOT OVERLY IMPRESSED WITH POTENTIAL FOR SEVERE STORMS IN THE OVERNIGHT. FOR SATURDAY OP GFS/EURO MODELS HAVE REALLY TRENDED UP WITH PRECIP COVERAGE THIS GO ROUND. THESE SOLUTIONS SEEM A LITTLE DUBIOUS WITH RESPECT TO THEIR HIGH RAIN CHANCES SO CLOSE TO THE CENTER OF THE SUBTROPICAL RIDGE AXIS...AND FOR THE OFFICIAL FORECAST I CUT MEX POPS IN CENTRAL AND SOUTHERN ZONES. A FEW BELIEVABLE HIRES MODELS DEPICT THE EARLY SATURDAY MORNING CONVECTIVE ACTIVITY SLIDING ESE ACROSS THE REGION THROUGH THE DAY (HITTING NORTHERN AND NORTHEASTERN ZONES MAINLY) AND THIS THOUGHT WAS INCORPORATED IN THE OFFICIAL FORECAST. SATURDAY NIGHT CONVECTION SHOULD ONCE AGAIN TEND TO END IN THE EVENING ALTHOUGH THERE WILL STILL BE SOME POTENTIAL OF ANOTHER OVERNIGHT COMPLEX IMPACTING NORTHERN ZONES. AS FAR AS HAZARDOUS WEATHER GOES...WILL CONTINUE TO MENTION LIMITED THREAT OF HEAT THROUGH THE SHORT TERM. NORTHERN ZONE HEAT WILL DEFINITELY BE LESS THAN IN THE SOUTH BUT COULD STILL BE QUITE STIFLING IN BETWEEN BOUTS OF STORMS. AS ALLUDED TO ABOVE...AT THIS POINT WILL CONTINUE TO HOLD OFF ON MENTIONING ANY SEVERE THREATS IN THE HWO ALTHOUGH A STRAY SEVERE STORM THROUGH THE PERIOD CANNOT BE RULED OUT. /BB/ SUNDAY THROUGH THURSDAY... GLOBAL MODEL CONSENSUS OUTPUT HAS THE SUBTROPICAL RIDGE ANCHORED OVER THE ARKLAMISS AS WE GO INTO SUNDAY. A HOT LOW LEVEL THERMAL RIDGE WITH H850 TEMPS 20-22 DEG C WILL CONTINUE TO SUPPORT SOME OF THE HOTTEST HEAT INDICES OBSERVED SO FAR THIS SUMMER. HOWEVER... CONVECTION EXPECTED TO DEVELOP BY LATE MORNING/EARLY AFTERNOON COULD DISTRUPT DAYTIME HEATING AND LIMIT HEAT STRESS...PARTICULARLY EAST OF THE DELTA REGION. IN ANY CASE... STEEP LOW- MID LEVEL LAPSE RATES WILL HELP TO INCREASE THE THREAT FOR STRONG/SEVERE STORMS. AS WE GO THROUGH EARLY INTO MID NEXT WEEK...INDICATIONS ARE THAT THE UPPER LEVEL PATTERN WILL BECOME MORE AMPLIFIED. NORTHWEST FLOW WILL BRING THE POTENTIAL FOR A FEW CONVECTIVE SYSTEMS WHILE THERMODYNAMIC PROFILES REMAIN FAVORABLE FOR STRONG/SEVERE STORMS. ONCE AGAIN...THE GFS SUGGESTS THERMODYNAMIC PROFILES SOUTH OF THE FRONTAL BOUNDARY COULD BE PRETTY IMPRESSIVE TUESDAY FOR GETTING INTENSE CONVECTION WITH THE H850 THETAE RIDGE AXIS ASSOC WITH THE THERMAL RIDGE MAXING OUT NEAR 352 DEG K WHILE VERTICAL TOTALS APPROACH 30. WILL CONTINUE TO MONITOR THIS TIME PERIOD FOR POTENTIAL STRONG/SEVERE STORMS. AS WE GO INTO MID WEEK THE UPPER LEVEL THROUGH OVER THE EASTERN CONUS WILL HELP TO SEND DRIER AND SLIGHTLY LESS HOT AIR TO THE ARKLAMISS...BUT WILL KEEP SOME POPS GOING FOR PRIMARILY SOUTHERN PORTIONS OF THE FORECAST AREA AS THE FRONTAL BOUNDARY IS EXPECTED TO STALL OUT. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
