The radar

The Miami radar (KAMX), 79 km from the middle of the area, began a volume at 00:22 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Miami, FL (KMFL), launched 00:00Z, 0.4 hours before the alert went out and 61 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at Jun 14, 7:23 PM EDT, 58 minutes earlier.

Area forecast discussion, Jun 14, 7:23 PM EDT, 58 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
723 PM EDT THU JUN 14 2012

.AVIATION...WL EXPECT MOSTLY VFR CONDITIONS OVERNIGHT. SLIGHT
THREAT OF TSTMS MOVING CLOSE TO KPBI LATER THIS EVENING AND A FEW
SHWRS CLOSE TO KFLL, KMIA. SFC WINDS SHOULD BECOME LIGHT AND
MOSTLY VARIABLE OVERNIGHT WITH SEA BREEZES DOMINATING ONCE AGAIN
FROM MID-MORNING FRIDAY ON. A FEW SHOWERS AND TSTMS COULD DEVELOP
ONCE AGAIN DURING THE AFTERNOON FRIDAY, BUT WL KEEP THEM OUT OF
THE TAFS FOR THE TIME BEING.

&&

.PREV DISCUSSION... /ISSUED 221 PM EDT THU JUN 14 2012/

DISCUSSION...
SEA BREEZES MOVING INLAND ACROSS THE REGION THIS AFTERNOON. SO FAR
ANY SHOWERS AND THUNDERSTORMS REMAIN WELL TO THE NORTH OF THE
AREA. WITH DEWPOINTS MIXING OUT BELOW 70 ACROSS THE SOUTHEAST
PORTION OF THE REGION...IT WILL BE DIFFICULT TO GET SHOWERS AND
THUNDERSTORMS THERE. STILL EXPECT SCATTERED ACTIVITY NEAR THE
LAKE REGION LATE THIS AFTERNOON AS THE FRONTAL BOUNDARY DRAPES
SLOWLY SOUTHWARD TOWARDS CENTRAL FLORIDA...WITH ISOLATED SHOWERS
AND STORMS ELSEWHERE ALONG THE SEA BREEZE BOUNDARIES. PATCHY FOG
COULD DEVELOP ACROSS THE INTERIOR LATE THIS EVENING...BUT
POTENTIAL IS LOW SO LEFT OUT OF FORECAST.

AS LOW PRESSURE REMAINS EAST OF FLORIDA ON FRIDAY AND THE
REMNANTS OF THE FRONTAL TROUGH APPROACH THE AREA...THE FORECAST
MODELS INDICATE HIGHER MOISTURE (NEAR NORMAL)...HEALTHIER LOW
LEVEL CONVERGENCE AND INCREASED INSTABILITY...ESPECIALLY AFTER
18Z. THE LOW TO MID LEVEL FLOW WILL SHIFT MORE TO THE NORTHEAST SO
THE BEST CHANCE OF PRECIP WILL BE ACROSS THE SOUTH AND WEST. SO
CHANCE POPS 30-40 PERCENT ARE EXPECTED ACROSS THE REGION FOR
FRIDAY AFTERNOON. THE REMNANTS OF THE FRONT WILL SLOWLY PASS
THROUGH THE REGION BEGINNING FRIDAY NIGHT AND CLEAR THE REGION BY
SATURDAY EVENING...WITH GRADUALLY IMPROVING CONDITIONS FROM
NORTHEAST TO SOUTHWEST. 30 POPS ARE STILL WARRANTED ON
SATURDAY. ONLY 20 POPS ON SUNDAY DUE TO LIMITED
INSTABILITY...AND PWATS DROP TO 2 STANDARD DEVIATIONS BELOW NORMAL
UNDER THE NORTHEASTERLY LOW LEVEL FLOW. THE PRESSURE GRADIENT
WILL ALSO TIGHTEN DURING THIS PERIOD...RESULTING IN BREEZY
CONDITIONS AS A BROAD TROUGH LINGERS OFF THE EASTERN SEABOARD AND
HIGH PRESSURE MOVES INTO THE SOUTHEAST STATES. MARINE SHOWERS WILL
REMAIN POSSIBLE THROUGH SUNDAY WITH SOME ALSO AFFECTING THE EAST
COAST...PARTICULARLY AT NIGHT AS COASTAL CONVERGENCE INCREASES.

A MID LEVEL TROUGH ALONG THE U.S. EAST COAST WILL KEEP ANY DEEP
TROPICAL MOISTURE TO OUR SOUTH AND EAST MONDAY INTO TUESDAY.
HOWEVER...INDICATIONS ARE THAT SOME MOISTURE MAY START SURGING
NORTHWEST INTO SOUTH FLORIDA BY NEXT WEDNESDAY. TEMPERATURES ARE
EXPECTED TO REMAIN NEAR NORMAL WITH HIGHS IN THE UPPER 80S TO LOW
90S EAST AND THE LOW TO MID 90S WEST.

AVIATION...
EARLY AFTERNOON VISIBLE SATELLITE IMAGERY INDICATES THE CU FIELD
BECOMING MORE ENHANCED DUE TO THE LAKE/EAST COAST BREEZES MERGING
ACROSS EASTERN PALM BEACH COUNTY. AS A RESULT...WILL START THE
PERIOD OUT WITH TSRA WORDING AND A TEMPO GROUP FOR THE PBI SITE AS
A FEW DEVELOPING SHOWERS/TSTMS BECOME A POSSIBILITY THROUGH THE
MID-AFTN PERIOD. THE LOCALLY RUN WRF/HRRR INDICATES MAINLY
ISOLATED TO SCATTERED AFTERNOON SHOWERS/TSTMS DEVELOPING WITH THE
BEST CHANCE REMAINING INLAND AND AROUND THE LAKE REGION THROUGH
THE EARLY EVENING HOURS BEFORE TRENDING BACK DOWN THROUGH THE
NIGHT TONIGHT. WINDS WILL REMAIN ONSHORE THROUGH THE AFTERNOON
PERIOD...THEN BECOME VRB AND EVEN OFFSHORE THROUGH THE LATE NIGHT
PERIOD. FOR FRIDAY...THE FRONTAL BOUNDARY NORTH OF THE LOCAL AREA
WILL CONTINUE SOUTH INTO THE AREA...WHICH SHOULD BE ENOUGH TO
SUPPORT AFTERNOON SHOWERS/TSTMS ONCE AGAIN. JUST HOW FAR THIS
FRONTAL BOUNDARY MAKES IT SOUTH WILL BE THE MAIN QUESTION AS TO
EXACTLY WHERE THE CONVECTION WILL INITIATE AS NORTHERLY WINDS AND
DRIER AIR SPREAD SOUTH IN ITS WAKE. 85/AG

MARINE...
A WEAK PRESSURE GRADIENT WILL REMAIN IN PLACE THROUGH TONIGHT WITH
WINDS 15 KNOTS OR LESS AND SEAS OF 2 TO 4 FEET. WIND SPEEDS WILL
BE A BIT STRONGER FRIDAY NIGHT THROUGH SUNDAY. IN ADDITION, A
NORTHEAST SWELL OF 2 TO 3 FEET MAY AFFECT PORTIONS OF THE ATLANTIC
WATERS THIS WEEKEND. OTHERWISE, ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS ARE EXPECTED THROUGH SUNDAY.

FIRE WEATHER...
NO SIGNIFICANT CONCERNS AS RELATIVE HUMIDITIES
WILL REMAIN ABOVE CRITICAL VALUES OVER AT LEAST THE NEXT FEW
DAYS.
