Area forecast discussion, Jun 6, 1:45 PM EDT, 37 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 145 PM EDT SUN JUN 6 2004 .DISCUSSION...NO MAJOR SYNOPTIC FEATURES TO AFFECT SOUTH FLORIDA NEXT SEVERAL DAYS. HOWEVER...THE SUBTLE CHANGES IN THE LOW/MID LEVEL RIDGE AXIS WILL OF COURSE DICTATE WHERE CONVECTION WILL BE FAVORED. THE MEAN LOW-MID LEVEL RIDGE IS TO GRADUALLY LIFT NORTHWARD LATE TOMORROW...ALLOWING THE FLOW TO BECOME PREDOMINANTLY ESE. THIS FLOW PATTERN IS EXPECTED TO CONTINUE THROUGH MID WEEK...KEEPING THE FAVORED CONVECTIVE AREAS ACROSS INTERIOR AND WESTERN PORTIONS OF SOUTH FLORIDA. BY LATE WEEK...THE MEAN WESTERN ATLANTIC RIDGE SLIDES SOUTHEASTWARD...SHIFTING THE FLOW TO SOUTHERLY...AND EVENTUALLY SOUTHWESTERLY BY NEXT WEEKEND...AS A TROUGH APPROACHES FLORIDA FROM THE NW. SO BY WEEKS END...THE FAVORED CONVECTIVE AREAS WILL SHIFT EASTWARD IN RESPONSE TO THIS CHANGE IN FLOW. GFS SHOWS MID LEVEL TEMPS MODERATING THROUGH MID WEEK WITH UPPER RIDGING IN PLACE. THIS WILL TEND TO KEEP THE THUNDERSTORMS THAT DEVELOP MORE TAME COMPARED TO THE PAST FEW DAYS...BUT STILL WILL CONTAIN LOCALLY HEAVY DOWNPOURS AND FREQUENT LIGHTNING. && .MARINE...MARINE CAMS, NOT SURPRISINGLY, SHOW VERY LOW SEAS...ALMOST LIKE GLASS IN PLACES. ESE FLOW WILL PICK UP JUST A BIT THIS WEEK...AS PRESSURE GRADIENT TIGHTENS...SO WINDS IN THE 10-15 KT RANGE CAN BE EXPECTED MUCH OF THIS WEEK. THIS WILL BRING SEAS INTO THE 2-4 FOOT RANGE. && .FIRE WEATHER...RHS WILL CONTINUE ABOVE CRITICAL LEVELS, SO NO PROBLEMS...ALTHOUGH IT SURE HAS BEEN DRY OF RECENT ACROSS MOST OF SOUTHEAST FLORIDA. SINCE YESTERDAY...FT. LAUDERDALE OFFICIALLY HAS RECEIVED ONLY 1.01 OF RAIN IN THE PAST 53 DAYS. MIAMI HASNT FAIRED ANY BETTER...WITH ONLY 0.31 OF RAINFALL IN THE PAST 33 DAYS...SINCE MAY 4TH, OVER A MONTH NEEDLESS TO SAY...RAIN WILL BE WELCOME HERE...AND SOME AREAS HAVE FINALLY RECEIVED SOME RAINFALL TODAY. THE BEST CHANCE FOR RAINFALL FOR THE EASTERN METROS THROUGH MID WEEK WILL BE MID-LATE MORNING TOMORROW...BEFORE THE ATLANTIC SEA BREEZE SWEEPS INLAND. THEN...TUE-THU...ACTIVITY MAY REMAIN JUST WEST OF THESE METRO AREAS AGAIN. ANY NIGHTTIME ACTIVITY IS NOT EXPECTED TO PRODUCE MUCH RAINFALL. && .PRELIMINARY POINT TEMPS/POPS...
