The episode as NWS JAX wrote it up.
A surface trough across SE Ga and NE Fl shifted south of the area through the day with low level easterly flow in its wake. East winds focused the best chances of afternoon and evening storms inland during the evening along and near the I-75 corridor where a few strong to severe storms developed.

NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Aug 27, 2:34 PM EST, 3 hours 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 334 PM EDT THU AUG 27 2015 .NEAR TERM.../THROUGH FRIDAY NIGHT/... REST OF THIS AFTERNOON...PRECIPITABLE WATER VALUES ARE LOWER THAN YESTERDAY...WITH THE DEEPEST MOISTURE ACROSS CENTRAL FLORIDA. THIS IS DELAYING SHOWER AND THUNDERSTORM ACTIVITY THUS FAR ACROSS THE REGION...WITH ONLY A FEW SHOWERS AND STORMS DEVELOPING ACROSS FLAGLER COUNTY. SHOWERS AND STORMS ARE STILL FORECAST TO BECOME SCATTERED TO NUMEROUS LATER THIS AFTERNOON TO THE SOUTHEAST OF THE SURFACE TROUGH AND ASSOCIATED FRONTAL BOUNDARY...THAT STRETCHED ACROSS SOUTHEAST GEORGIA SOUTHWESTWARD INTO THE GULF OF MEXICO. TONIGHT...STORMS WILL CONTINUE INTO THE EVENING HOURS UNDER THE SOUTHERLY FLOW...THEN SLOWLY DIMINISH WITH LOSS OF DAYTIME HEATING. SURFACE HIGH PRESSURE WILL BUILD SOUTH INTO THE SOUTHEAST STATES OVERNIGHT...WITH LOW LEVEL FLOW SHIFTING TO THE NORTHEAST AND EAST. NOCTURNAL SHOWERS AND STORMS ARE FORECAST FOR THE ATLANTIC WATERS...AND WITH COASTAL CONVERGENCE INCREASING OVERNIGHT...KEPT A CHANCE OF SHOWERS AND SLIGHT CHANCE OF THUNDER FOR THE COASTAL COUNTIES. LOWS WILL BE IN THE 70S. FRIDAY...UPPER LEVEL TROUGH WILL CUTOFF ACROSS THE NORTHERN GULF COAST JUST SOUTH OF LOUISIANA...WITH DIFFLUENT SOUTHWESTERLY FLOW ALOFT ACROSS THE REGION. A WEAK SHORTWAVE MAY ALSO PUSH NORTHWARD INTO NORTHEAST FLORIDA FRIDAY AFTERNOON. AT THE SURFACE...A WEAK AREA OF LOW PRESSURE OVER THE PANHANDLE OF FLORIDA WILL CONTINUE TO RETROGRADE WESTWARD AND WEAKEN. ANOTHER WEAK AREA OF LOW PRESSURE MAY DEVELOP EAST OF THE CAROLINAS ALONG AN INVERTED TROUGH. EASTERLY LOW LEVEL WINDS WILL PREVAIL AS HIGH PRESSURE CENTERED ACROSS THE MID ATLANTIC STATES MOVES EAST. MOISTURE WILL INCREASE THROUGHOUT THE COLUMN...WITH PRECIPITABLE WATER VALUES INCREASING TO 1.8-2 INCHES ACROSS THE REGION. SCATTERED TO NUMEROUS SHOWERS AND STORMS ARE FORECAST...WITH SHOWERS AND A FEW STORMS ONGOING IN THE MORNING. .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT... WET PATTERN CONTINUES INTO THE WEEKEND AS WESTERN EXTENT OF MID LEVEL RIDGE BUILDS OVER THE FL PENINSULA FROM THE EAST AND ADDITIONAL MOISTURE ADVECTS NORTHWARD ACROSS MUCH OF THE SE US. CHANCES FOR SHOWERS AND TSTORMS INCREASE INTO EACH AFTERNOON AS SFC LAYER HEATS UP WITH HIGHEST COVERAGE EXPECTED DURING THE LATE AFTERNOON/EARLY EVENING HOURS BEFORE SLOWLY DIMINISHING OVERNIGHT. LOCALLY HEAVY RAINFALL COULD BE AN ISSUE EACH AFTERNOON WITH WEAK STEERING FLOW AND HIGH MOISTURE LEVELS PRODUCING SOME SLOW MOVING STORMS. SFC HIGH CENTERED TO OUR NORTH WILL ALLOW CONTINUED EAST TO SOUTHEASTERLY FLOW AND DEVELOPMENT OF ISOLATED TO SCATTERED SHOWERS AND TSTORMS DURING THE OVERNIGHT HOURS OVER THE COASTAL WATERS WHICH COULD AFFECT COASTAL LAND AREAS EACH NIGHT. INCREASED CLOUD COVER WILL KEEP TEMPS IN THE UPPER 80S/LOW 90S EACH AFTERNOON WITH MILD LOWS IN THE LOW/MID 70S. .LONG TERM /MONDAY THROUGH WEDNESDAY NIGHT/... MAIN CONCERN FOR THE LONG TERM PERIOD WILL BE THE STRENGTH...TIMING...AND TRACK OF TS ERIKA. CURRENTLY...THERE IS STILL MUCH UNCERTAINTY IN THE THE FORECAST FOR THIS STORM EARLY NEXT WEEK WITH THE MOST RECENT UPDATE ON THE TRACK OF ERIKA PLACING THE CENTER JUST OFFSHORE OF TITUSVILLE BY TUESDAY MORNING AS HURRICANE. THE FUTURE TRACK OF THIS STORM IS DEPENDENT ON ITS INTENSITY AND INTERACTION WITH HISPANIOLA INTO THIS WEEKEND. LONG TERM MODEL TRENDS DIVERGE WITH THE GFS INDICATING A STRONGER STORM CURVING MORE TO THE NORTHWEST PROGRESSING UP THE EAST COAST OF FL AND THE ECMWF SHOWING A WEAK STORM CURVING LESS SIGNIFICANTLY AND TRACKING UP THE FL PENINSULA. THE CURRENT LOCAL FORECAST LEANS MORE TOWARDS THE GFS SOLUTION WITH ENHANCED RAIN CHANCES...PRIMARILY IN COASTAL AREAS... MONDAY THROUGH WEDNESDAY AND WINDY CONDITIONS BEGINNING MONDAY NIGHT. COASTAL AND INLAND FLOODING ALONG WITH BEACH EROSION AND HIGH SURF COULD BE ISSUES IF THE STRONGER STORM SOLUTION MATERIALIZES AND SIGNIFICANT RAINFALL TOTALS ARE RECEIVED. WPC GUIDANCE STILL INDICATING 7 DAY RAINFALL TOTALS BETWEEN 5 TO 7 INCHES IN COASTAL NE FL WITH HIGHEST TOTALS JUST OFFSHORE. AGAIN...THERE IS LITTLE CERTAINTY IN THIS LONG TERM FORECAST AND LOCAL INTERESTS SHOULD CONTINUE TO MONITOR THIS STORMS PROGRESSION. && .AVIATION... INCLUDED TEMPO TSRA FOR 20-00Z KGNV/KVQQ WHERE MAY BE BETTER COVERAGE THAN FOR TAF SITES FURTHER EAST WHERE JUST KEPT VCTS. VFR CONDITIONS EXPECTED OUTSIDE TSRA. SOUTHEAST WINDS 5-10 KNOTS THIS AFTERNOON WILL BECOME LIGHT AND VARIABLE OVERNIGHT. A FEW SHOWERS ARE POSSIBLE NEAR THE COASTAL TAF SITES OVERNIGHT...BUT LEFT OUT MENTION OF SHOWERS ATTM. HIGH PRESSURE WILL BUILD SOUTH OVERNIGHT AND WINDS WILL BECOME EASTERLY 5-10 KNOTS BY LATE MORNING AT THE TAF SITES. SHOWERS AND STORMS WILL INCREASE IN COVERAGE BY THE END OF THE TAF PERIOD. && .MARINE... LIGHT WINDS THIS AFTERNOON WILL BECOME EASTERLY AROUND 10 KNOTS OVERNIGHT AS HIGH PRESSURE BUILDS NORTH OF THE REGION. SCATTERED TO NUMEROUS CONVECTION IS FORECAST ACROSS THE ATLANTIC WATERS OVERNIGHT. LIGHT EAST TO SOUTHEAST WINDS WILL CONTINUE INTO THE WEEKEND. ATTENTION THEN SHIFTS TO TROPICAL STORM ERIKA SUNDAY INTO EARLY NEXT WEEK AS THE STORM TRACKS TOWARDS SOUTHEAST FLORIDA...AND THEN POSSIBLY NORTHWARD UP THE COAST. TROPICAL STORM CONDITIONS ARE POSSIBLE ON MONDAY. FOR MORE INFORMATION ON TROPICAL STORM ERIKA...REFER TO THE HURRICANE CENTER AT WWW.HURRICANES.GOV.
