NWS Miami, FL wrote its last area forecast discussion before the first event at Jun 29, 9:11 AM EST, 3 hours 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 1011 AM EDT SUN JUN 29 2014 .SYNOPSIS... 12Z SOUNDING ANALYSIS SHOWS TWO DISTINCT INVERSIONS...ONE NEAR 800MB AND THE OTHER AT THE 500MB LEVEL. USING BACKWARD TRAJECTORY ANALYSIS...THE SLIGHTLY STRONGER MID LEVEL CAPPING INVERSION ORIGINATED FROM SUBSIDENCE WRAPPING AROUND MID LEVEL RIDGING ACROSS THE NORTH CENTRAL GULF OF MEXICO. THE LOWER AND WEAKER INVERSION CAN BE TRACED FROM A LAYER OF SAHARAN DUST WELL TO THE SOUTH OF THE AREA ACROSS CUBA STRETCHING WESTWARD TO THE YUCATAN PENINSULA AND INTO THE WESTERN GULF OF MEXICO. BELIEVE THIS WILL HELP TO DELAY THE ONSET OF CONVECTION AND CAN BE SUBSTANTIATED BY THE LACK OF ANY CU FIELD THUS FAR. FORECAST PARAMETERS LOOK GOOD AT THIS TIME AND NO UPDATES ARE CURRENTLY PLANNED. && .PREV DISCUSSION... /ISSUED 736 AM EDT SUN JUN 29 2014/ AVIATION... AS THE LOW PRESSURE AREA OFF THE SE UNITED STATES COAST MOVES SOUTH THIS WILL PLACE SOUTH FLORIDA UNDER A LIGHT NORTH-NORTHWEST FLOW ABOVE THE SURFACE AND LEAD TO GREATER COVERAGE OF SHOWERS/TSTMS OVER THE AREA, ESPECIALLY OVER THE EASTERN AREAS. INCLUDED VCTS STARTING 16Z ALONG WITH THE ONSET OF THE SEA BREEZES. FOR APF AND MIA INCLUDED TEMPO GROUPS. THE ENDING TIME OF PRECIPITATION IS A LITTLE TRICKY TO PIN DOWN AS CONVECTION COULD LINGER LATE INTO THE EVENING IN THE NORTHERLY FLOW. FOR NOW ENDED THE VCTS AT 00Z BUT WOULDN'T BE SURPRISED IF LATER FORECASTS DELAY THE ENDING BY A FEW HOURS. && .PRELIMINARY POINT TEMPS/POPS...
