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 8, 2:33 PM EDT, 23 minutes earlier.
Area forecast discussion, Jun 8, 2:33 PM EDT, 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 233 PM EDT FRI JUN 8 2007 .DISCUSSION...MID LEVEL TROUGH CURRENTLY JUST OFF THE SE CST OF THE FLA PENINSULA NEAR GRAND BAHAMA. THE GFS INITIALIZED QUITE WELL AND SINCE IT IS THE MODEL THAT HAS HANDLED THIS LOW THE BEST WILL GO MOSTLY WITH ITS SOLUTION. THIS LOW IS LYING BENEATH A LARGE MID LEVEL RIDGE THAT STRETCHES ACROSS THE SOUTHERN PLAINS STATES INTO THE SOUTHEAST INCLUDING NORTH FLA. PLENTY OF MOISTURE TO WORK WITH THIS AFTERNOON INTO THE EVENING AS ABUNDANT SUNSHINE THIS MORNING CREATED A LOT OF INSTABILITY. STILL WITH DECLINING INSTABILITY AFTER SUNSET, THINK THE MAV GUIDANCE HAS TOO HIGH POPS FOR TONIGHT AND WILL UNDERCUT THOSE NUMBERS. A SHORTWAVE MOVING INTO THE WEST COAST OF THE U.S. WILL GET CUT OFF OVER THE DESERT SOUTHWEST ON SATURDAY WHILE A LARGE CUT OFF LOW OVER THE NORTH ATLANTIC WILL DRIFT EASTWARD. ALL OF THIS WILL RESULT IN THE RIDGE TO BUILD EASTWARD AND ALLOW THE MID LEVEL LOW IN OUR REGION TO CONTINUE DRIFTING WESTWARD UNDERNEATH THE RIDGE AXIS AND WEAKEN AS IT GETS INTO THE SOUTHEAST GOFMEX. AS THE LOW DOES MOVE INTO THE SOUTHEAST GULF THIS WILL THEN DRAG DRIER AIR ON THE NORTH SIDE OF THE LOW ACROSS S FLA ON SATURDAY WITH THIS TREND CONTINUING INTO SUNDAY AND NEXT WEEK. && .AVIATION...NO SIGNIFICANT CHANGES TO THE AVIATION FORECAST AT THIS TIME...AS SHORT TERM MODELS CONTINUE TO INDICATE THE DEVELOPMENT OF WIDESPREAD CONVECTION THIS AFTERNOON...AS MID-LEVEL DESTABILIZATION OCCURS WITH APPROACH OF RETROGRADING UPPER LOW CURRENTLY NORTH OF THE BAHAMAS. WILL MAINTAIN VCTS WORDING THIS AFTERNOON/EARLY EVENING FOR ALL TERMINALS AND VCSH THEREAFTER...WITH BULK OF CONVECTION ONCE AGAIN EXPECTED TO OCCUR OVER THE INTERIOR PORTION OF THE PENINSULA. OTHERWISE...VFR CONDITIONS WILL PERSIST OUTSIDE OF ANY SHOWERS/STORMS...WITH SCT- BKN CU AND AC/AS DECKS. SURFACE WINDS WILL REMAIN EASTERLY AT ALL ATLANTIC COAST TERMINALS. A MORE PRONOUNCED SEA BREEZE IS POSSIBLE IN THE AFTERNOON AT KAPF. 70/DD && .MARINE...OUTSIDE OF DODGING CONVECTIVE ACTIVITY, WINDS WILL BE AT 15 KT OR LESS WITH SEAS 5 FEET OR LESS THROUGH THE FORECAST CYCLE. && .FIRE WEATHER...NO PROBLEMS OR CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...
