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 12:00Z, 7.8 hours before the alert went out and 126 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.

Area forecast discussion, Jul 1, 3:01 PM EDT, 49 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
301 PM EDT THU JUL 1 2010

...VERY WET START TO THE FOUR OF JULY WEEKEND WITH CONTINUE
UNSETTLE WEATHER THROUGH THE FOUR OF JULY WEEKEND OVER SOUTH
FLORIDA...

.DISCUSSION...
THE EAST AND WEST COAST SEA BREEZES HAS DEVELOPED EARLY THIS
AFTERNOON WITH SHOWERS AND THUNDERSTORMS ALONG THE SEA BREEZES.
THE EAST COAST SEA BREEZE WILL CONTINUE TO PUSH ACROSS THE
INTERIOR AREAS THIS AFTERNOON WHILE THE WEST COAST SEA BREEZE
REMAINS NEAR OVER THE WESTERN METRO AREAS OF THE CWA...AS SHOWERS
AND THUNDERSTORMS CONTINUE TO DEVELOP ALONG BOTH SEA BREEZES. SO
WILL CONTINUE TO KEEP LIKELY POPS OVER THE INTERIOR AND WEST COAST
AREAS FOR THE AFTERNOON HOURS.

THE LOCAL WRF MODEL IS INDICATING THAT A FEW SHOWERS AND
THUNDERSTORMS COULD WORK BACK INTO THE EAST COAST METRO AREAS LATE
THIS AFTERNOON INTO THIS EVENING ALONG THE OUTFLOW BOUNDARIES OF
THE INTERIOR STORMS. THE LOCAL WRF MODEL ALSO SHOW THIS YESTERDAY
AND IT HAPPEN. SO WILL KEEP SCATTERED POPS OVER THE METRO AREAS
FOR THIS AFTERNOON...WITH ISOLATED POPS OVER THE EAST COASTAL
AREAS.

THE LATEST DERIVED SATELLITE IMAGES CONTINUE TO SHOW THAT THE 500
MB TEMPS ARE STILL PRETTY COLD WITH -8 TO -9C OVER SOUTH FLORIDA...DUE
TO THE UPPER LEVEL LOW OVER THE FLORIDA STRAITS. SO WILL CONTINUE
TO MENTION SOME STRONG STORMS OVER THE INTERIOR AND WEST COAST
METRO AREAS THIS AFTERNOON INTO EARLY THIS EVENING.

THE UPPER LEVEL LOW SHOULD WEAKEN TONIGHT...AS IT MOVES INTO
CENTRAL CUBA. THIS WILL ALLOW A TROPICAL WAVE LOCATED OVER THE
CENTRAL CARIBBEAN SEA TO MOVE TO THE WEST TO NORTHWEST AND CLIP
SOUTH FLORIDA ON FRIDAY. THE LATEST SSMI SATELLITE IMAGES SHOW
DEEP TROPICAL MOISTURE AHEAD OF THE WAVE THAT SHOULD MOVE INTO
SOUTH FLORIDA ON FRIDAY WITH PWAT VALUES BETWEEN 2.1 AND 2.3
INCHES. THIS IS RUNNING CLOSE TO THE 2 STANDARD DEVIATIONS ABOVE
THE NORMAL OF 1.7 INCHES FOR THIS TIME OF YEAR. THEREFORE...HAVE
RAISE THE POPS ON FRIDAY TO LIKELY CAT FOR ALL AREAS EXCEPT
DEFINITE OVER THE LAKE OKEECHOBEE AREA ALONG WITH LOCALLY HEAVY
RAINFALL.

ONCE THIS TROPICAL WAVE MOVES NORTH OF THE CWA FRIDAY NIGHT...A
TROUGH OF LOW PRESSURE OVER NORTH FLORIDA WILL MOVE SOUTH AND
STALL OVER LAKE OKEECHOBEE OR OVER SOUTH FLORIDA THIS WEEKEND.
THIS WILL KEEP THE PWAT VALUES AROUND 2 INCHES...AND ALLOWED FOR
SCATTERED SHOWERS AND THUNDERSTORMS EACH DAY THIS FOUR OF JULY
WEEKEND.

AT THIS TIME...IT LOOKS LIKE IT WILL BE THE DIURNAL SHOWER AND
THUNDERSTORM ACTIVITY WITH LATE NIGHT AND MORNING ACTIVITY EACH
COAST AND AFTERNOON AND EVENING ACTIVITY WEST COAST.

.EXTENDED FORECAST...
THE LATEST LONG RANGE MODELS ARE SHOWING THAT THE THROUGH OF LOW
PRESSURE WILL WASH OUT EARLY NEXT WEEK OVER SOUTH FLORIDA...AS AN
UPPER LEVEL LOW MOVES SOUTHEAST FROM THE MID ATLANTIC STATES INTO
THE FLORIDA PENINSULA MIDDLE OF NEXT WEEK. THIS WILL KEEP THE
WEATHER UNSETTLE OVER THE CWA FOR THE MIDDLE TO END OF NEXT WEEK.
SO WILL KEEP THE SCATTERED POPS OVER THE CWA FOR THE MIDDLE TO END
OF NEXT WEEK.

&&

.MARINE...
THE WINDS SPEEDS WILL REMAIN AT 5 TO 10 KNOTS TONIGHT THROUGH
FRIDAY NIGHT. THE DIRECTION WILL BE SOUTHEAST TONIGHT...BEFORE
GOING NORTHEAST FRIDAY MORNING THEN SOUTHERLY FRIDAY AFTERNOON
WITH THE PASSAGE OF THE NORTHERN PORTION OF THE TROPICAL WAVE. THE
WINDS WILL THEN REMAIN SOUTHEAST THIS WEEKEND AT LESS THAN 10
KNOTS. THE SEAS WILL REMAIN BELOW 6 FEET OVER BOTH THE ATLANTIC
AND GULF WATERS. THERE COULD BE A SMALL WESTERLY SWELL OF 1 TO 2
FOOT IN THE GULF WATERS OF SOUTH FLORIDA LATE TONIGHT INTO FRIDAY
MORNING. SO AT THIS TIME DO NOT EXPECT ANY PROBLEMS IN THE COASTAL
WATERS OF SOUTH FLORIDA AND LAKE OKEECHOBEE THIS FOUR OF JULY
WEEKEND.

&&

.FIRE WEATHER...
THE RELATIVE HUMIDITIES WILL REMAIN WELL ABOVE 35 PERCENT CRITICAL
VALUE THROUGH THE FOUR OF JULY WEEKEND. SO NO PROBLEMS WITH THE
FIRE WEATHER.
