Area forecast discussion, Aug 7, 3:39 PM EDT, 2 hours 26 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 339 PM EDT SAT AUG 7 2010 ...LOCALLY HEAVY RAIN POSSIBLE EAST COAST METROPOLITAN AREAS SUNDAY AFTERNOON AND ALL OF SOUTH FL ON MONDAY... .DISCUSSION...A MID TO UPPER LEVEL TROUGH IS MOVING INTO THE SOUTHEASTERN STATES...AND THIS IS PROVIDING DIVERGENCE ACROSS THE SOUTHWESTERN ATLANTIC...AND FLARING UP CONVECTION ON WHAT IS A REMNANT OLD FRONTAL BOUNDARY LYING OFF THE NORTHEAST/EAST CENTRAL FL COAST. 07.12Z GFS AND 07.00Z ECMWF AGREE ON THE TROUGH AMPLIFYING AND BECOMING BETTER DEFINED IN THE MID LEVELS...AND EVENTUALLY DOWN TO THE SURFACE...EITHER INTO AN OPEN INVERTED TROUGH OR POSSIBLY A LOW. MOVEMENT WILL BE TOWARDS THE WSW OR SW...WITH THE GFS FURTHER SOUTH OVER SOUTH FL AND THE ECMWF ACROSS THE PENINSULA TO OUR NORTH. EITHER WAY...DEEP TROPICAL MOISTURE WILL CONTINUE IN PLACE...AND EVEN INCREASE...OVER THE NEXT FEW DAYS WITH PW VALUES IN THE 2.25-2.50 INCH RANGE. THIS COULD LEAD TO LOCALLY HEAVY RAINFALL ACROSS THE EAST COAST METROPOLITAN AREAS ON SUNDAY AFTERNOON AND ACROSS ALL OF SOUTH FL ON MONDAY AS THE TROUGH OR LOW MOVES ACROSS THE PENINSULA. SEE HYDROLOGY SECTION BELOW FOR MORE DETAILS ON RAINFALL EXPECTATIONS. THE TROUGH OR LOW WILL PULL AWAY FROM THE AREA DURING THE MIDDLE PART OF THE WEEK WITH THE RIDGE BUILDING BACK NORTH...LEADING TO A MORE CLIMATOLOGICAL PATTERN FOR THE EXTENDED PERIOD. MADE NO CHANGES TO THE EXTENDED FCST. && .HYDROLOGY...HPC QPF SUN-MON SHOWS 2-3 INCHES AREA WIDE...IN LINE WITH BOTH GFS AND NAM MOS QPF. THIS LOOKS REASONABLE GIVEN THE DEEP TROPICAL MOISTURE AND CONVERGENCE EXPECTED. THE CONCERN WILL BE FOR THE POSSIBILITY OF TRAINING/BACK-BUILDING OF CELLS WHICH COULD LEAD TO LOCALIZED RAINFALL AMOUNTS OF 4-6 INCHES. LATER SHIFTS CAN ASSESS TRENDS TO SEE IF A FLASH FLOOD WATCH MAY BE NEEDED. HOWEVER...AT THIS TIME THE SCENARIO LOOKS TO PLAY OUT TO WHERE IT WOULD BE BEST HANDLED WITH URBAN FLOOD ADVISORIES...AS ANY EXCESSIVE RAIN LOOKS TO BE LOCALIZED. && .MARINE...TRANQUIL CONDITIONS...AS FAR AS PREVAILING WINDS/SEAS...WILL CONTINUE OVER THE LOCAL WATERS THROUGH THE PERIOD. HOWEVER...TSTORM COVERAGE WILL BE ON THE INCREASE OVER THE ATLANTIC WATERS TONIGHT - ESPECIALLY OFF THE PALM BEACH COAST...THEN ALL AREAS SUN AFTERNOON THROUGH MONDAY. GIVEN THE TSTORM RISK DURING THIS TIME...NOT A GOOD TIME TO PLAN TO BE OUT ON THE WATERS. && .FIRE WEATHER...NO CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...
