Area forecast discussion, Jul 19, 2:38 PM EDT, 37 minutes before
AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE MIAMI FL 238 PM EDT SUN JUL 19 2009 .DISCUSSION... ...CORRECTED PRELIM POINT TEMPS/POPS SECTION BELOW/NO OTHER CHANGES... THE LARGE-SCALE PICTURE CURRENTLY SHOWS A STRONG MID/UPPER TROUGH DIGGING INTO THE NRN/CENTRAL GULF OF MEXICO WITH A STRONG DEEP-LAYER RIDGE ACROSS THE CENTRAL ATLANTIC. THIS GENERAL LARGE-SCALE PATTERN WILL PERSIST INTO WEDNESDAY BEFORE THE EASTERN CONUS TROUGH LIFTS N OF THE REGION...AND DEEP-LAYER RIDGE AXIS BUILDS SOUTHWEST ACROSS THE REGION ONCE AGAIN LATE IN THE WEEK. FOR THE REST OF TODAY...THUNDERSTORMS HAVE DEVELOPED ACROSS THE INTERIOR AND ALONG LAKE BREEZE CONVERGENCE IN WESTERN PALM BEACH COUNTY. A FEW STORMS HAVE ALSO GOTTEN GOING ALONG THE EAST COAST SEA BREEZE IN THE MIAMI AREA...BUT HAVE STRUGGLED TO DEVELOP SO FAR ALONG THE REMAINDER OF THE SEA BREEZE. THINK STORMS WILL CONTINUE TO INCREASE AND MOVE NE BACK TOWARDS THE EAST COAST METRO AREAS LATE THIS AFTERNOON/EARLY THIS EVENING BEFORE ACTIVITY DISSIPATES OR MOVES OFFSHORE BY MIDNIGHT. FOR MONDAY...THE DEPARTING SAHARAN AIR LAYER COMBINED WITH THE AMPLIFYING MID/UPPER TROUGH TO THE WEST COULD LEAD TO MORE TSTM ACTIVITY. THE NAM TAKES A WELL-DEFINED SHORTWAVE WITHIN THE LONGWAVE TROUGH AXIS SOUTHEAST INTO THE ERN GULF BY MORNING WITH CONVECTION MARCHING EAST FROM THE GULF AND REALLY GOING CRAZY AS IT HITS THE EAST COAST SEA BREEZE. THE GFS KEEPS THIS ACTIVITY CLOSER TO THE LAKE OKEECHOBEE REGION/CENTRAL FL. FEEL THAT EITHER WAY WE SHOULD HAVE MORE CONVECTION TOMORROW DUE TO INFLUENCE FROM THE TROUGH...THOUGH THE NAM SHOWING SEVERAL INCHES OF RAIN ACROSS THE EAST COAST METRO AREAS IS LIKELY WELL OVERDONE. ON TUESDAY...MOST MODELS ARE INDICATING THAT THE NORTHERN EXTENT OF THE AXIS OF THE TROPICAL WAVE CURRENTLY OVER THE EASTERN CARIBBEAN WILL BREAK OFF BRINGING A LOW-LEVEL THROUGH THE BAHAMAS...THOUGH THE NAM IS CURIOUSLY ABOUT A DAY SLOWER. GUIDANCE NOW AGREES THAT THE BULK OF THE MOISTURE WILL GET SUCKED TO THE NORTH JUST TO OUR EAST...IN BETWEEN THE TROUGH TO THE WEST AND RIDGE TO THE EAST. DESPITE THAT...PWATS STILL APPROACH 2 INCHES WITH DEEPENING/SLIGHTLY INCREASING SERLY FLOW...AND THIS SHOULD LEAD TO AN INCREASE IN CONVECTIVE COVERAGE REGION WIDE. THE LOW LEVEL TROUGH PASSES THROUGH TUESDAY NIGHT AND THIS COULD CAUSE THE SHOWER/STORM CHANCE TO LINGER OVERNIGHT. WEDNESDAY MAY END UP BEING A LITTLE DRIER THAN PREVIOUSLY ADVERTISED AS THE TROUGH LIFTS NORTH...AND THE GFS INDICATES SOME MID LEVEL DRYING AND SUBSIDENCE POSSIBLY WORKING INTO THE REGION...BUT NOT ENOUGH TO COMPLETELY LIMIT DIURNAL CONVECTION. HAVE NOT MADE ANY CHANGES FOR WEDNESDAY YET AND WILL LET LATER SHIFTS TAKE A LOOK AT LATEST MODEL DATA BEFORE CHANGING. THURSDAY THROUGH SATURDAY...THE DEEP-LAYER RIDGE AXIS FROM THE ATLANTIC BUILDS SW ACROSS THE FL KEYS/STRAITS AND THIS SHOULD BRING THE REGION BACK INTO SWRLY STEERING FLOW WITH LIGHT TO CALM LOW LEVEL FLOW. AS A RESULT...A RETURN TO SEA BREEZE DRIVEN CONVECTION MOVING BACK TOWARDS THE EAST COAST SEEMS IN ORDER THIS PERIOD. WILL MAKE NO CHANGES TO THE EXTENDED FCST AT THIS TIME. && .MARINE... GENERALLY EAST TO SOUTHEAST WINDS 5 TO 10 KNOTS WILL CONTINUE THE NEXT FEW DAYS...BUT WINDS COULD INCREASE TO 10 TO 15 KNOTS BEHIND THE SFC TROUGH WED/THU TIMEFRAME. SEAS GENERALLY 2 FEET OR LESS BUT COULD INCREASE SOME WED/THU DEPENDING ON HOW MUCH WINDS INCREASE. && .FIRE WEATHER... NO CONCERNS AS LOW LEVEL MOISTURE WILL REMAIN PLENTIFUL. && .PRELIMINARY POINT TEMPS/POPS... WEST PALM BEACH 76 89 75 88 / 30 60 30 50 FORT LAUDERDALE 79 90 78 88 / 30 50 30 50 MIAMI 79 91 78 88 / 30 50 30 50 NAPLES 78 90 75 90 / 20 50 20 40 && .MFL WATCHES/WARNINGS/ADVISORIES... FL...NONE.
