The episode as NWS JAN wrote it up.
The combination of rich gulf moisture, instability, and strong moisture convergence aided in providing strong storms over portions of Central Mississippi mainly during the afternoon hours. These storms caused some street flooding in Warren County. In addition there was some thunderstorm wind damage in the form of blown down trees and power lines.
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 Jun 13, 9:40 AM CST, 2 hours 55 minutes earlier.
AREA FORECAST DISCUSSION...UPDATE NATIONAL WEATHER SERVICE JACKSON MS 1040 AM CDT SAT JUN 13 2015 .UPDATE... POPS WERE UPPED 5 TO 15 PERCENTAGE POINTS IN MOST AREAS THROUGH THE REMAINDER OF THE DAY AFTER HAVING A LOOK AT MORNING OBSERVATIONS/MODELS AND TRENDS. 12Z RAOBS SHOW LOTS OF FLOW AND INLAND GULF MOISTURE TRANSPORT ON THE BACKS OF SSE LOW LEVEL WIND VECTORS ALTHOUGH THERE ARE POCKETS OF RELATIVE DRYNESS ALOFT WHICH MAY INHIBIT CONVECTIVE DEVELOPMENT AT TIMES AND IN SPOTS. THE BRUNT OF MOISTURE TRANSPORT AND CONVERGENCE IS CURRENTLY FOCUSED AT A LINE OF LOCALLY HEAVY RAIN AND STORMS ADVANCING SLOWLY NNE FROM CENTRAL/NORTH CENTRAL LA TOWARD SE AR AND NE LA. THERE IS SOME UNCERTAINTY HOW THIS ACTIVITY WILL EVOLVE INTO THE EARLY AFTERNOON AS THE HRRR IS HESITANT TO KEEP IT AS A PERSISTENT FEATURE. HOWEVER...THIS BAND WILL HAVE TO BE WATCHED CLOSELY AS IT COULD PRESENT HEAVY RAIN ISSUES FOR PORTIONS OF THE DELTA IF IT HOLDS TOGETHER AND STALLS. AT THIS POINT THIS LATTER RISK IS RATHER CONDITIONAL SO WE WILL CONTINUE TO KEEP THE HWO CLEAR. OTHERWISE...MAIN REASONING FOR POP RAISING TODAY WAS BECAUSE BANDS OF SHOWERS AND STORMS THAT DO DEVELOP SHOULD EXHIBIT LOTS OF SOUTH TO NORTH MOVEMENT AND WILL WET A LOT OF GROUND. IT MUST ALSO BE UNDERSTOOD THAT SOME LOCATIONS COULD GET SEVERAL SHOWERS BUT RELATIVELY LIMITED RAINFALL OWING TO THIS SAME ASPECT. BUT THOSE LOCATIONS THAT DO GET SOLID STORMS WILL ALSO GET AT LEAST BRIEFLY GUSTY WINDS DUE PURELY TO MOMENTUM TRANSFER. CONSIDERING TAME LAPSE RATES ALOFT THESE CONVECTIVE GUSTS SHOULD ONLY BE A CONSIDERABLE WORRY IF SURFACE INSTABILITY BUILDS MORE THAN IS ANTICIPATED. /BB/ && .AVIATION...AFTER STARTING OFF THE MORNING WITH FAIRLY WIDESPREAD IFR CONDITIONS DUE TO STRATUS...START OF DAYTIME MIXING HAS ALLOWED CONDITIONS TO IMPROVE TO MVFR OR VFR MOST LOCATIONS. MAIN FOCUS FOR THIS AFTERNOON WILL BE POTENTIAL FOR GUSTY TSRA WITH PERIODS OF MVFR/IFR CIGS POSSIBLE DUE TO VERY HIGH MOISTURE LEVELS. HRRR RUNS IMPLY FAIRLY WIDESPREAD COVERAGE OF TSRA THIS AFTERNOON AS MODERATELY STRONG LOW LEVEL FLOW ALLOWS STORMS TO PROPAGATE AND HAVE FAIRLY HIGH COVERAGE. HENCE HAVE AT LEAST TEMPO TSRA MOST SITES AND WILL AMD AS NEEDED TO SHOW CATEGORICAL IMPACTS BASED ON RADAR TRENDS. EXPECT REPEAT OF WIDESPREAD IFR CONDITIONS LATER TONIGHT DUE TO STRATUS WITH FAIRLY SIMILAR SETUP TO WHAT WAS OBSERVED THIS MORNING. /AEG/ && .PREV DISCUSSION... /ISSUED 540 AM CDT SAT JUN 13 2015/ UPDATE... HAVE UPDATED MORNING FORECAST TO INCLUDE FOG OVER SOUTH/EAST CENTRAL MS BASED ON RECENT OBS TRENDS. FOG SHOULD NOT PERSIST FOR LONG AFTER SUNRISE GIVEN BOUNDARY LAYER FLOW/MIXING EXPECTED. /EC/ PREV DISCUSSION... /ISSUED 425 AM CDT SAT JUN 13 2015/ DISCUSSION... TODAY THROUGH SUNDAY NIGHT... DEEP SOUTHERLY FLOW BETWEEN A TROUGH OVER THE WESTERN HALF OF THE GULF OF MEXICO AND A SUBTROPICAL HIGH CENTERED OVER THE SOUTH ATLANTIC STATES CONTINUES TO FORCE A VERY MOIST AIRMASS (PRECIPITABLE WATER ~ 1.8 TO 2.2 INCHES) NORTHWARD INTO THE ARKLAMISS REGION. WITH DAYTIME HEATING AND SUBSTANTIAL LOW/MID LEVEL SOUTHERLY FLOW HELPING TO ORGANIZE SHOWERS/TSTMS ALONG OUTFLOW BOUNDARIES...CONVECTIVE PRECIPITATION COVERAGE SHOULD BE CONSIDERABLE AGAIN TODAY...BUT THERE MAY BE A WESTWARD SHIFT TO THE ACTIVITY TODAY AS THE RIDGE BEGINS TO EXPAND WESTWARD AND EXERT MORE INFLUENCE INTO EASTERN MS. TODAY'S FORECAST POPS REFLECT THIS THINKING AND FOLLOW THE MULTITUDE OF NEAR TERM GUIDANCE INCLUDING THE SPC SSEO AND OTHER HIGH-RES WRF GUIDANCE. POPS WILL LIKELY NEED TO BE UPDATED AND INCREASED IN SOME AREAS DEPENDING ON CONVECTIVE TRENDS LATER THIS MORNING. LAPSE RATES WILL BE A HAIR STEEPER TODAY THAN YESTERDAY...BUT STILL EXPECT VERTICAL TOTALS TO BE LESS THAN 26 FOR MOST PART WITH 0-3 KM LAPSE RATES NOT MUCH GREATER THAN 7.5 TO 8 DEG C/KM. A FEW STRONG WIND GUSTS AND PERHAPS A COUPLE OF SEVERE WIND REPORTS WILL BE POSSIBLE...ESPECIALLY WHERE CONVECTION IS MORE DELAYED ALLOWING FOR GREATER DESTABILIZATION...WHICH COULD END UP BEING IN NORTHERN/ EASTERN PORTIONS OF THE AREA GIVEN THAT INITIAL DEVELOPMENT SHOULD BE ALONG/SOUTH OF THE HWY 84 CORRIDOR. LOCALLY HEAVY RAINFALL WILL BE POSSIBLE AS WELL BUT...IN SIMILAR FASHION TO YESTERDAY...STORM MOTIONS ARE EXPECTED TO BE RELATIVELY SWIFT AND UNSUPPORTIVE OF HEAVY RAINFALL DURATIONS THAT COULD LEAD TO FLASH FLOODING POTENTIAL. STORMS THAT ORIENT ALONG WEST TO EAST BOUNDARIES WILL BE MOST LIKELY TO PRODUCE STRONG WIND GUSTS. WITH BUILDING HEIGHTS OVER THE AREA...THERE SHOULD BE A GREATER DIURNAL PATTERN TO THE CONVECTION WITH SHOWERS/STORMS DIMINISHING QUICKLY IN THE EARLY EVENING FOLLOWED BY MINIMAL RAIN CHANCES OVERNIGHT. FOR SUNDAY THROUGH SUNDAY NIGHT...EXPECT GREATER INSTABILITY/MOISTURE TO BECOME MORE FOCUSED OVER WESTERN PORTIONS OF THE ARKLAMISS AS THE SOUTHEAST CONUS RIDGE INTENSIFIES AND EXPANDS WESTWARD. THIS WILL MEAN DECREASING POPS FOR EASTERN MS - BUT WITH PRECIPITABLE WATER REMAINING NEAR TWO INCHES ALONG/W OF THE MS RIVER...HAVE KEPT HIGHER POPS GOING THERE IN THE FORECAST FOR SUNDAY AFTN. A SIMILAR THERMODYNAMIC SET-UP SHOULD YIELD THE POTENTIAL FOR A FEW STRONG STORMS AGAIN SUNDAY AFTERNOON. HAVE INCREASED CONSENSUS GUIDANCE HIGH TEMPERATURES SLIGHTLY AND CUT LOWS A BIT BASED ON RECENT TRENDS. /EC/ MONDAY THROUGH FRIDAY...OF INTEREST IS THE DISORGANIZED TROPICAL WAVE OVER CENTRAL AMERICA PUSHING TOWARD THE YUCATAN PENINSULA. THE GFS AND CANADIAN MODELS HAS THIS WEAK WAVE PUSHING INLAND OVER THE NORTHWEST GULF COAST THEN PUSH IT NORTH INTO THE ARKLATEX REGION DURING THE WORKWEEK. MOREOVER...THE CANADIAN MODEL HAS THIS WAVE COMBINING WITH A WEAK SHORT WAVE FOR A LITTLE BETTER AMPLIFICATION AND INCREASED LOW/MID LEVEL FLOW (~25-40 KNOTS) HELPING TO BRING SOME STRONG THUNDERSTORM POTENTIAL GENERALLY WEST OF THE MS RIVER. THE ECMWF MODEL HAS A WEAKER SHEAR AXIS LOCATED FARTHER WEST THROUGH CENTRAL TEXAS. A PLUME OF MOISTURE WITH PWATS AROUND 2.3 INCHES WILL SURGE ACROSS THE WEST PORTION OF THE REGION...WHICH WILL PUSH THE DRIER AIR EAST OF THE REGION. THIS WILL BRING THE POTENTIAL OF EFFICIENT LOCALLY HEAVY RAINFALL OVER THE WEST. THE GFS LOOKS TO BE TOO FAR EAST WITH THE HIGHER PWATS. MODELS ARE STILL SHOWING THE BEST RAINFALL AMOUNTS DOWN AROUND THE COASTAL AREAS. THIS IS THE FIRST MODEL RUN SHOWING THIS WAVE SO WELL IN THE LOW TO MIDLEVELS AS FAR AS JET ENERGY IS CONCERNED. EXPECT MAINLY DIURNALLY DRIVEN CONVECTION FOR THE PERIOD. SO WITH THIS IN MIND WILL KEEP THE HWO CLEAR FOR NOW SINCE THE ECMWF WAS FARTHER WEST WITH THE BETTER JET DYNAMICS. WILL WATCH FOR FUTURE MODEL RUNS WITH THIS FEATURE./17/ && .PRELIMINARY POINT TEMPS/POPS...
