What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Miami, FL wrote its last area forecast discussion before this flash flood warning went out at Jun 7, 2:20 PM EDT, 1 hour 18 minutes earlier.

Area forecast discussion, Jun 7, 2:20 PM EDT, 1 hour 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
220 PM EDT FRI JUN 7 2013

.SHORT TERM (TONIGHT THROUGH SUNDAY NIGHT)...
A BOUNDARY EXTENDING TO THE SOUTHWEST OF T.S. ANDREA CURRENTLY IS
LOCATED ACROSS SOUTH FLORIDA AND THIS IS A FOCUSING MECHANISM FOR
CONVERGENCE WITH THE DEVELOPMENT OF AFTERNOON SHOWERS AND
THUNDERSTORMS AS DIURNAL HEATING ENSUES FOR THE REST OF TODAY. THE
12Z MFL SOUNDING WAS INDICATING A SMALL THREAT FOR TORNADO FORMATION
ESPECIALLY IF A SEA BREEZE DEVELOPS ALONG THE EAST COAST AND CAN
PUSH INLAND EVEN IF IT IS A FEW MILES. GLOBAL MODELS ARE IN GOOD
AGREEMENT THAT ANDREA WILL CONTINUE TO LIFT TO THE NORTHEAST ALONG
THE EASTERN SEABOARD AND BE OFF THE NEW ENGLAND COAST BY SATURDAY
AFTERNOON. THE CONVERGENCE BOUNDARY AS THIS OCCURS WILL REMAIN
NEARLY STATIONARY ACROSS SOUTH FLORIDA WITH ANOTHER GOOD CHANCE FOR
LATE MORNING/AFTERNOON CONVECTION. FORECAST SOUNDINGS ALSO SHOW THE
PWAT REMAINING OVER TWO INCHES. AS ANDREA MOVES FAR TO THE NORTH OF
SOUTH FLORIDA, SURFACE HIGH PRESSURE WILL BEGIN TO BUILD BACK TO THE
WEST SO LOW LEVEL FLOW WILL BECOME MORE SOUTHEAST. THUS, RATHER THAN
THE STEERING FLOW TODAY OF SW-NE IT WILL BECOME MORE SSW-NNE AND THE
GREATEST IMPACT APPEARS THAT IT WILL SHIFT MORE TO THE NORTHERN
COUNTIES RATHER THAN THE ENTIRE EAST COAST AND THE GRIDS WILL
REFLECT THIS. BY SUNDAY, ANDREA WILL CONTINUE TO MOVE NORTHEAST INTO
THE NORTH ATLANTIC AND THIS WILL ALLOW A DEEP LAYER RIDGE TO BUILD
WEST AND THIS WILL BRING A BIT OF MID LEVEL DRYING FOR THE REGION
WITH LESSER CHANCES FOR RAINFALL. BOTH THE MAV AND MET GUIDANCE SHOW
THIS TREND WHICH LOOKS REASONABLE. ALSO, AS THE DEEP LAYER RIDGE
BUILDS IN THE STEERING FLOW WILL SHIFT THE HIGHEST POPS TO THE
INTERIOR AND WEST COAST BUT PWAT WILL DROP TO WELL UNDER TWO INCHES.

.LONG TERM (MONDAY THROUGH FRIDAY)...
THE DEEP LAYER RIDGE WILL REMAIN IN PLACE ON MONDAY BUT A STRONG MID
LEVEL TROUGH WILL MOVE INTO THE GREAT LAKES REGION ON TUESDAY WITH
ITS TROUGH AXIS EXTENDING SOUTH AND AS IT LIFTS TO THE NORTHEAST
ANOTHER TROUGH WILL TAKE ITS PLACE TOWARDS THE END OF THE WEEK. THIS
WILL ERODE THE RIDGE WITH FORECAST SOUNDINGS SHOWING STEERING FLOW
TO BECOME VERY WEAK INDICATING STORMS WILL BE MORE SEA BREEZE DRIVEN
AND CONFINED MORE TO THE INTERIOR AND THIS TREND ALREADY INDICATED
SO NEED TO CHANGE THIS FOR NOW.

&&

.AVIATION...
WIDELY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS CONTINUE TO
DEVELOP MAINLY ACROSS THE EASTERN HALF OF THE PENINSULA...WITH
TERMINALS KFXE...KFLL AND KOPF POSSIBLY EXPERIENCING BRIEF PERIODS
OF IFR CONDITIONS THROUGH 19Z. THE POTENTIAL FOR FURTHER CONVECTION
AND THUNDERSTORMS WILL CONTINUE FOR ALL EAST COAST TERMINALS THROUGH
AT LEAST 23Z IF NOT FURTHER INTO THE EARLY EVENING WITH ALL EAST
COAST TERMINALS ASSIGNED VCTS THROUGH AT LEAST THAT PERIOD...WITH
BRIEF IFR CONDITIONS POSSIBLE WITH ANY THUNDERSTORMS AND/OR HEAVY
SHOWERS. LIGHT SHOWERS AND/OR MFVR CEILINGS MAY BE POSSIBLE FOR
TERMINAL KAPF THROUGH AT LEAST THE EARLY EVENING HOURS.

&&

.MARINE...
WIND WILL SLOWLY BACK TO THE EAST TO SOUTHEAST OVER THE WEEKEND
FROM A SOUTHERLY DIRECTION THIS AFTERNOON AS HIGH PRESSURE BUILDS
IN FROM THE ATLANTIC. THIS WILL RESULT IN TRANQUIL SEAS OUTSIDE OF
THUNDERSTORMS THROUGH THE MIDDLE OF NEXT WEEK.

&&

.FIRE WEATHER...
NO PROBLEMS OR CONCERNS WITH AMPLE TROPICAL MOISTURE.
