AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
203 PM EDT SUN JUN 22 2008

.DISCUSSION...

CURRENT/TONIGHT...EAST COAST BREEZE BOUNDARY HAS BEEN CRAWLING
INLAND ACROSS THE SPACE COAST. BOUNDARY IS MAKING BETTER PROGRESS
INLAND OVER THE TREASURE COAST. THE ECSB FEATURE WILL BE FOCUS FOR
DEVELOPMENT OF PERHAPS A STRONG STORMS OR TWO OVER THE NEXT TWO TO
THREE HOURS. ANOTHER BATCH OF STORMS ASCD WITH GULF SYNOPTIC INFLUENCE
IS MOKING LANDFALL OVER THE WEST PEINSULA AND MAY PRESENT ANOTHER
CHANCE OF SHRA/TSRA THIS EVENING. FROM WEST TO EAST. WILL HOLD
ONTO A MENTIONABLE RAIN CHANCE THROUGH THE EVENING WITH POPS
TAPERING TO ISOLATED IN COVERAGE PAST 00Z AND ENDING BY 03Z AS
AIRMASS GETS WORKED OVER ALONG WITH LOSS OF HEATING.

MON...EASTERN CONUS UPR TROUGHING WILL KEEP HIGH PRESSURE
SUPPRESSED TO OUR SOUTH AND MAINTAIN W-SW FLOW REGIME OVER THE
AREA. GFS INDICATES SOME DIVERGENCE ALOFT...COOL MID LEVEL TEMPS
AND DEEP MOISTURE. POPS WILL CONTINUE TO RUN ABOVE NORMAL WITH
LIKELY COVERAGE OVER THE NORTH AND SOMEWHAT LESSER BUT STILL ABV
NORMAL CHC OF STORMS OVER THE SOUTH.

*** PREV DISCUSSION ***

TUE-WED...EASTERN CONUS TROUGH WILL LIFT OUT WHICH WILL ALLOW
LOW/MID LEVEL RIDGE TO SHIFT BACK TO THE NORTH.  THE GFS SHOWS
SOUTHERN PORTION OF UPPER LEVEL TROUGH LAGGING BEHIND OVER THE
NORTHEAST GULF THOUGH...SO DEEP DRYING IS NOT EXPECTED. THE MAIN
DIFFERENCES SHOULD BE THE POSITIONING OF HIGHEST POPS AS STEERING
FLOW BECOMES WEAK TUE THEN SHIFTS CONVECTION INLAND ON WED.
CURRENT FORECAST INDICATING 40 POPS AREAWIDE TUE...DECLINING TO 30
PERCENT TUE EXCEPT FOR 40 PERCENT IN THE SOUTH STILL LOOKS GOOD.

THU-SAT...GFS CONTINUES TREND OF SHOWING MOISTURE INCREASING ACROSS
THE SOUTH ON THU IN ASSOCIATION WITH TROPICAL WAVE STARTING TO ROUND
THE BASE OF DEEP LAYER ATLANTIC RIDGE.  THIS FEATURE IS FORECAST TO
SHEAR APART WITH SOUTHERN PORTION SHIFTING INTO THE CENTRAL/WESTERN
GULF FRI-SAT AND MOISTURE ASSOCIATED WITH NORTHERN PORTION LINGERING
OVER THE LOCAL AREA.  LOW LEVEL RIDGE AXIS WILL EXTEND NORTH OF THE
AREA BUT ONSHORE FLOW SHOULD BE LIGHT AS REMNANTS OF TROUGH LINGER
...BUT WOULD EXPECT POPS TO TRANSITION MORE TO A NIGHT/MORNING
REGIME ALONG THE COAST...ESPECIALLY THE SOUTH...THEN CONVECTION
SHIFTING TO THE INTERIOR DURING THE AFTERNOON/EVENING. HAVE NOT
CHANGED PREVIOUS CHANCE POPS MUCH SINCE THEY ARE IN PRETTY GOOD
AGREEMENT WITH LATEST MEX NUMBERS.

&&

.AVIATION...
SCT TSRA ALL LOCATIONS THROUGH 23Z WITH SLOW DECREASE THROUGH
02Z. ANOTHER WAVE FROM TH GULF COAST MAY AFFECT WESTERN SITES FM
LEE-MCO/ISM THIS EVENING. AFFECTED LOCATIONS WL SEE MVFR/IFR
CONDITIONS WITH PREDOMINANT VFR DVLPG AFT 03Z. LCL BR AFT 10Z WL
REDUCE LCL VSBYS TO AROUND 3-5 MILES SFB-DAB THROUGH 12Z MONDAY
MORNING.

.MARINE...
WEST FLOW AROUND 5 TO 10 KTS WITH SEAS AROUND 1 TO 2 FEET
EXPECTED. ONLY CONCERN OVER THE COASTAL WATERS TODAY WILL BE
OFFSHORE MOVING SHOWERS AND THUNDERSTORMS IN W/SW FLOW ACROSS THE
AREA.

MON-THU...WINDS WILL TRANSITION FROM AN OFFSHORE FLOW TO ONSHORE
DURING THIS PERIOD...ESPECIALLY SOUTHERN LEG. OFFSHORE MOVING
STORMS WILL OCCUR AGAIN ON MON AND POSSIBLY TUE IN THE NORTH.
INCREASED MOISTURE FROM THE SOUTHEAST SHOULD PRODUCE GREATER THAN
NORMAL SHOWER AND STORM CHANCES ACROSS THE SOUTH WED-THU.
