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.

THUNDERSTORMS: SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP
ACROSS THE AREA THIS AFTERNOON AND EVENING. THE STORMS ARE
EXPECTED TO BECOME MOST CONCENTRATED ACROSS THE INTERIOR AND THE
ATLANTIC COAST LATE THIS AFTERNOON AND THIS EVENING. THE

50 MPH. HOWEVER, ONE OR TWO SEVERE STORMS COULD DEVELOP, CAPABLE
OF PRODUCING DAMAGING WINDS OF 60 TO 70 MPH.

HAIL: THE MOST INTENSE STORMS LATE THIS AFTERNOON WILL BE CAPABLE
OF PRODUCING PENNY TO QUARTER SIZE HAIL.

FLOODING: SLOW MOVING THUNDERSTORMS COULD GENERATE HEAVY RAINFALL
IN A FEW LOCATIONS THIS AFTERNOON. THIS MAY LEAD TO ISOLATED
STREET FLOODING AND FLOODING OF POORLY DRAINED AREAS.

TEMPERATURES: HIGH TEMPERATURES IN THE MID 90S WILL COMBINE WITH
THE HIGH HUMIDITY TO RESULT IN APPARENT TEMPERATURES REACHING
AROUND 105 DEGREES ACROSS MUCH OF THE AREA.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

SCATTERED THUNDERSTORMS ARE EXPECTED EACH AFTERNOON AND EVENING
THROUGH THE PERIOD.

.SPOTTER INFORMATION STATEMENT...
