What was reported inside it

Time	Report	Where	Remark
Jul 1, 5:15 PM EDT	TSTM WND GST 45	1 S Marco Island, FL	A THUNDERSTORM PRODUCED A WIND GUST OF 45 MPH MEASURED VIA EARTH NETWORKS AT THE MARCO ISLAND MARRIOT BEACH RESORT.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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, 8.8 hours before the alert went out and 141 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 Jul 1, 3:19 PM EDT, 1 hour 29 minutes earlier.

Area forecast discussion, Jul 1, 3:19 PM EDT, 1 hour 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
319 PM EDT WED JUL 1 2015

.DISCUSSION...
A DEEP EASTERLY FLOW HAS SET UP ACROSS SOUTH FLORIDA AS A RIDGE
BUILDS BACK INTO THE REGION BOTH AT THE SURFACE AND ALOFT. THIS
PATTERN WILL PERSIST FOR THE NEXT SEVERAL DAYS INCLUDING THE
HOLIDAY WEEKEND WITH AFTERNOON SHOWERS AND THUNDERSTORMS
CONCENTRATED OVER THE INTERIOR AND GULF COAST. A RATHER THICK SAL
(SAHARAN AIR LAYER) WILL CONTINUE ACROSS SOUTH FLORIDA THROUGH
THURSDAY GIVING THE SKY A MILKY OR HAZY LOOK. THIS IS ALSO EVIDENT
ON THE 12Z MFL SOUNDING SHOWING VERY STEEP MID LEVEL LAPSE RATES
AT 7.1C/KM. ALTHOUGH THE PWAT IS BARELY OVER 1.5", THE STEEP LAPSE
RATES COULD FUEL A COUPLE OF STRONG STORMS LATE THIS AFTERNOON.
THE PAST FEW RUNS OF THE HRRR HAVE SHOWN WHERE THE STORMS
CURRENTLY ARE LOCATED AND THEN DRIFT TOWARDS THE NAPLES AREA LATE
IN THE AFTERNOON. A FEW CELLS ARE CURRENTLY DEVELOPING JUST TO THE
NORTHEAST OF NAPLES SO THIS SCENARIO SEEMS REASONABLE. ACCORDING
TO THE NAVAL RESEARCH LAB MODEL, THE SAL WILL THIN SOMEWHAT ON
FRIDAY AND SATURDAY BUT ANOTHER THICK LAYER WILL BE APPROACHING
THE SOUTHEAST COAST EARLY NEXT WEEK AND MAY PERSIST INTO THE
MIDDLE OF THE WEEK.

FORECAST SOUNDINGS INDICATE PWAT IN THE RANGE OF 1.5-1.7" THROUGH
THIS PERIOD SO STORM COVERAGE WILL GENERALLY BE AROUND 40-60% EACH
DAY EXCEPT 20-30% ALONG THE EAST COAST. A COUPLE OF STRONG STORMS
OVER THE INTERIOR ON THURSDAY AFTERNOON CANNOT BE RULED OUT WITH THE
SAL STILL IN THE AREA. THE GFS IS SHOWING A MOISTURE SURGE ON FRIDAY
AND SATURDAY AS A COUPLE OF TROPICAL WAVES PASS TO OUR SOUTH SO
THERE COULD BE AN INCREASE IN COVERAGE THOSE TWO DAYS. HOWEVER, THE
ECMWF DOES NOT SHOW THE MOISTURE SURGE SO COVERAGE WOULD REMAIN
ABOUT THE SAME. ON THESE TWO DAYS AS THE WAVES MOVE THROUGH THE
WESTERN CARIBBEAN, THE GFS DOES SHOW THE STEERING FLOW TO BACK
MORE TO A SSE DIRECTION SO AFTERNOON STORMS COULD BE MORE
CONCENTRATED AROUND THE LAKE REGION AND AWAY FROM THE GULF COAST
BUT THE ECMWF CONTINUES THE DEEP EASTERLY FLOW.

ALSO THROUGH THE NEXT SEVERAL DAYS, A GENERAL MID LEVEL CYCLONIC
FLOW WILL CONTINUE ACROSS THE EASTERN U.S. WITH THE RIDGE OVER
CENTRAL FLORIDA. BY EARLY NEXT WEEK, THE GFS SHOWS A STRONGER MID
LEVEL TROUGH MOVING THROUGH THE CYCLONIC FLOW WITH A SURFACE LOW
PRESSURE DEVELOPING ALONG THE CAROLINAS COAST AND VEERING THE
STEERING FLOW ACROSS SOUTH FLORIDA TO A WESTERLY DIRECTION. HOWEVER,
THE ECMWF DOES NOT SHOW THE DEEPENING TROUGH AND INSTEAD MAINTAINS
AN EASTERLY FLOW ACROSS SOUTH FLORIDA.
