The episode as NWS JAX wrote it up.
Deep and moist SW flow with 20-25 knots of 0-6km steering flow on the east side of a deepening upper level trough brought widespread thunderstorm activity across the Suwannee River Valley of northeast Florida by midday where isolated wet downburst activity caused some tree and power line damage.
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 Jacksonville, FL wrote its last area forecast discussion before the first event at Jun 30, 9:13 AM EST, 2 hours 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 1013 AM EDT SUN JUN 30 2013 ...STRONG STORMS WITH GUSTY WINDS AND LOCALLY HEAVY RAINFALL POSSIBLE THIS AFTERNOON... .UPDATE... DEEP AND MOIST SOUTHWEST FLOW CONTINUES ACROSS THE REGION WITH MORNING SOUNDINGS SHOWING AN AMAZING 20-25 KNOTS OF 0-6KM STEERING FLOW...WHICH IS FAIRLY STRONG FOR LATE JUNE AND HAS BASICALLY SHUT DOWN THE LOCAL SEA-BREEZE REGIME. THIS WILL ALLOW FOR MAINLY NUMEROUS SHOWER ACTIVITY TO DEVELOP OUT OF THE NORTHEAST GOMEX AND TRACK ACROSS THE FORECAST AREA IN THE DEEP TROPICAL/MOIST AIRMASS WITH PRECIP WATER AMOUNTS OF JUST OVER 2 INCHES. EMBEDDED STORM ACTIVITY WILL REACH ITS HIGHEST COVERAGE DURING THE PEAK HEATING OF THE AFTERNOON HOURS AND WITH STORM MOTION PUSHING CLOSE TO 25 MPH...EXPECT ANY STORM TO HAVE GUSTS OF 30-40 MPH WITH STRONGER ONES HAVING THE POTENTIAL TO BECOME STRONG TO SEVERE. LOCALLY HEAVY RAINFALL WILL BE MORE DUE TO TRAINING OF ACTIVITY OUT OF THE GOMEX SINCE THE STORM MOTION IS RELATIVELY FAST. A BIT MORE INSOLATION AND LESS CLOUD COVER SHOULD ALLOW FOR MAX TEMPS TO PUSH INTO THE UPPER 80S TO NEAR 90 BEFORE CONVECTION BREAKS OUT IN MOST PLACES BY EARLY AFTERNOON. EVEN THOUGH SNAPSHOT STORM COVERAGE WILL REMAIN GENERALLY ISOLATED TO SCATTERED...THE QUICK STORM MOTION WILL ALLOW OVERALL COVERAGE TO BE LIKELY AROUND 60-70%. ACTIVITY WILL BEGIN TO FADE IN INTENSITY AND COVERAGE AROUND SUNSET WITH ACTIVITY STILL PUSHING IN OFF THE GOMEX INTO THE I-75 CORRIDOR OF NORTHEAST FLORIDA/SUWANNEE RIVER VALLEY THROUGH THE OVERNIGHT HOURS. && .AVIATION... ROUND OF SHOWERS/TSTMS WITH TEMPO MVFR CIGS/VSBYS WILL IMPACT THE TAF SITES MAINLY IN THE 16Z-19Z TIME FRAME IN THIS FAST SOUTHWEST FLOW AND EXPECT GUSTY WINDS UP TO 25-30 KTS POSSIBLE AS WELL. A LULL IN ACTIVITY IS EXPECTED AT TAF SITES BY THE 00Z TIME FRAME AND JUST A GENERAL VCSH SHOULD COVER MOST OF THE NIGHT WITHOUT ANY ORGANIZED ACTIVITY IMPACTING THE SITES. SOME LOW IFR STRATUS WILL BE POSSIBLE AT KGNV OVERNIGHT (06Z-12Z) BUT CONFIDENCE STILL TOO LOW TO INCLUDE AT THIS TIME. && .MARINE... S TO SW FLOW AT 15-20 KNOTS WILL CONTINUE WITH SEAS OF 3-5 FT INTO TONIGHT. OFFSHORE MOVING THUNDERSTORMS WITH GUSTY WINDS WILL BE POSSIBLE THIS AFTERNOON AND EARLY EVENING. RIP CURRENTS: LOW RISK WILL CONTINUE WITH THE MAINLY OFFSHORE FLOW. && .PRELIMINARY POINT TEMPS/POPS...
