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 7, 3:22 PM EDT, 3 hours 32 minutes earlier.

Area forecast discussion, Jun 7, 3:22 PM EDT, 3 hours 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
322 PM EDT SUN JUN 7 2009

...STRONG TO SEVERE STORMS POSSIBLE INTERIOR AND EAST COAST METRO
AREAS THIS AFTERNOON INTO THIS EVENING...
...BACK TO MORE NORMAL SUMMER CONDITIONS THIS WEEK ACROSS SOUTH FLORIDA...

.DISCUSSION...
THE UPPER LEVEL TROUGH OF LOW PRESSURE WAS LOCATED FROM ABOUT
MELBOURNE SOUTHWEST TO FORT MYERS EARLY THIS AFTERNOON. THIS
TROUGH WILL CONTINUE TO MOVE EAST ACROSS THE CWA THIS AFTERNOON
INTO THIS EVENING. AT THE SAME TIME...A MCV THAT DEVELOPED OVER
THE SOUTHEAST GULF OF MEXICO EARLY LATE THIS MORNING WILL ALSO
MOVE EAST ACROSS THE SOUTHERN AREAS OF THE CWA. THESE FEATURES
WILL HELP CONTINUE OVER THE CWA THIS AFTERNOON. SO WILL CONTINUE
WITH THE NUMEROUS POPS OVER SOUTH FLORIDA THIS AFTERNOON.

THE SHOWER AND THUNDERSTORM ACTIVITY SHOULD SLOWLY DISSIPATE THIS
EVENING OVER THE CWA...AS THE TROUGH OF LOW PRESSURE AND THE MCV
MOVES EAST INTO THE ATLANTIC WATERS ALONG WITH THE LOST OF THE
HEATING OF THE DAY. SO WILL CONTINUE WITH THE CHANCE POPS FOR
THIS EVENING OVER THE AREA...BEFORE GOING DRY AFTER MIDNIGHT OVER
THE LAND AREAS AND KEEPING A SLIGHT CHANCE FOR THE GULF AND
ATLANTIC WATERS.

THE COLD AIR ALSO STILL REMAINS OVER SOUTH FLORIDA THIS AFTERNOON
WHICH WILL HELP TO GENERATE STRONG TO SEVERE STORMS OVER THE
INTERIOR AND EAST COAST METRO THIS AFTERNOON INTO EARLY THIS
EVENING. COUPLE OF THE STORMS ARE ALSO ALREADY GOING SEVERE EARLY
THIS AFTERNOON OVER METRO PALM BEACH COUNTY WITH QUARTER SIZE
HAIL. SO WILL CONTINUE TO MENTION THIS IN THE HWO AND THE INTERIOR
AND EAST COAST ZONES FOR THIS AFTERNOON INTO THIS EVENING.

THE RIDGE OF HIGH PRESSURE WILL THEN BUILD INTO SOUTH FLORIDA ON MONDAY
INTO WEDNESDAY ALLOWING FOR THE STEERING FLOW TO BE LIGHT.
THEREFORE...THE SEA BREEZES WILL BE THE MAIN PLAYERS EACH DAY THAT
WILL PUSH INLAND INTO THE INTERIOR AREAS. SO HAVE KEPT SCATTERED
POPS OVER THE CWA EACH DAY WITH THE HIGHEST POPS OVER THE INTERIOR
AREAS.

.EXTENDED FORECAST...
THE LONG RANGE MODELS ARE STILL SHOWING A WEAK LOW IN THE
SOUTHWEST CARIBBEAN SEA TO DRIFT NORTHWARD LATE THIS WEEK INTO
THIS WEEKEND TOWARDS CUBA. THIS WILL ALLOW FOR THE PRESSURE
GRADIENT TO TIGHTEN A LITTLE BIT OVER SOUTH FLORIDA THIS WEEKEND...AND
ALLOW FOR SOME TROPICAL MOISTURE TO WORK INTO THE CWA FROM THE
CARIBBEAN SEA LATE THIS WEEKEND. SO HAVE KEPT THE WINDS BREEZY
ALONG THE EAST COAST AREAS THIS WEEKEND...AND INCREASE THE POPS TO
HIGH IN CHANCE OVER THE CWA LATE THIS WEEKEND.

WILL CONTINUE TO MONITOR THE LATEST LONG RANGE MODELS ON THE TRACK
AND STRENGTH OF THE LOW IN THE SOUTHWEST CARIBBEAN SEA THROUGH
THIS WEEK...AND ADJUST THE EXTENDED GRIDS IF NEED BE TO THE LATEST
LONG RANGE MODELS.

&&

.MARINE...
THE WINDS WILL REMAIN SOUTHERLY TONIGHT INTO WEDNESDAY OVER THE
CWA LESS THAN 10 KNOTS. THIS WILL KEEP THE SEAS LESS THAN 2 FEET
IN THE GULF STREAM AND IN THE ATLANTIC WATERS. SO NO HEADLINES FOR
THE LOCAL CWA WATERS THROUGH MIDDLE OF THIS WEEK, AND BOATING
CONDITIONS SHOULD BE GOOD OUTSIDE OF THE SHOWERS AND THUNDERSTORMS.

&&

.FIRE WEATHER...
THE RELATIVE HUMIDITIES SHOULD BE REMAIN ABOVE THE THE 35 PERCENT
CRITICAL VALUE THROUGH MIDDLE OF THIS WEEK...DUE TO THE TROPICAL
MOISTURE IN PLACE. SO NO PROBLEMS WITH THE FIRE WEATHER PRODUCTS.
