AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
316 PM EDT THU MAY 6 2010

.DISCUSSION...

TONIGHT-TOMORROW...DISSIPATING FRONTAL BAND LOCATED IN VICINITY OF
INTERSTATE 4 SAGGING VERY SLOWLY DOWN THE PENINSULA...IF NOT NEARLY
STATIONARY. SCATTERED CONVECTION ORGANIZED IN VICINITY OF THIS
BOUNDARY HAS BECOME OCCASIONALLY STRONG DURING THE EARLY AFTERNOON.
ALONG AND SOUTH OF THIS BOUNDARY...AIRMASS REMAINS RATHER JUICY WITH
DEW POINTS IN THE LOW 70S AND PLENTY OF MOISTURE TO WORK WITH BELOW
700MB (BUT DRIER ABOVE). EAST COAST SEA BREEZE BECOMING EVIDENT
SOUTH OF DAYTONA BEACH TO OFFER FURTHER FOCUS TO COVECTION. WITH
COOLER TEMPERATURES ALOFT...AND MAX HEATING NEAR THE SURFACE...AND
PLENTY OF PRIMARY AND SECONDARY BOUNDARIES...EXPECT STORMS TO BECOME
STRONG TO MARGINALLY SEVERE THROUGH THE EARLY EVENING...MAINLY FROM
ORLANDO EASTWARD AND ALONG THE EAST COAST. GUSTS APPROACHING 50KT
NOT UNREASONABLE GIVEN DRY AIR ALOFT...AND SMALL HAIL GIVEN COOLER
TEMPERATURES ALOFT.

FRONTAL BOUNDARY HARDLY DISCERNIBLE FOR FRIDAY AS THE SURFACE RIDGE
RE-ESTABLISHES DOMINANCE...WITH AXIS ACROSS THE FORECAST AREA.
MODELS TEND TO DISAGREE ON THE EXTENT OF DEEPER LAYER
DRYING/SUBSIDENCE WHICH WILL HAVE A BEARING ON TOMORROWS CONVECTIVE
FORECAST. MOS POPS TAKE THINGS TO BELOW MENTION...BUT WILL KEEP
ISOLATED TSTRMS ALL LOCATIONS...WITH BEST CHANCES ALONG THE TREASURE
COAST. WARM AGAIN TOMORROW WITH MAX TEMPERATURES INTO THE LOW
90S...EXCEPT IN VICINITY OF THE COAST BEHIND THE SEA BREEZE.

(PREVIOUS EXTENDED)...
FRI NITE-SUN...UPSTREAM RIDGING OVER GULF AREA WILL SLOWLY EDGE
TOWARD THE AREA WITH SLOW DRYING TREND INTO THE WEEKEND. FRI AFTN
HAVE INTRODUCED A SLIGHT CHC OF STORMS OVER THE SOUTH NEAR LAKE OKEE
AND THE TREASURE COAST DUE TO WEAK SFC TROUGH AND BREEZE BOUNDARY
INTERACTIONS WITH SUITABLE MOISTURE. SATURDAY WARM AND DRY. NEXT
FRONT APPROACHES FROM THE NORTH EARLY SUNDAY WITH LITTLE WEATHER
EXPECTED ASIDE FROM AN INCREASE IN MID-UPR CLOUDS. COOLER CONDITIONS
HOWEVER BY EARLY NEXT WEEK WITH HIGHS BACK INTO THE 80S AND LOWS IN
THE UPR 60S.

EXTENDED...HIGH PRESSURE WL BUILD SOUTH FROM THE MID ATLC SEABOARD
MILD ONSHORE FLOW EARLY IN THE WEEK WILL MODIFY SLOWLY AS FLOW
VEERS TO EAST AND EVENTUALLY SOUTHEAST ON TUE. GUID CONTS TO
SUGGEST LOW GRADE POP MAINLY INLAND BY MON AFTN AND INTO TUE DUE
TO BREEZE CONVERGENCE AND DIURNAL HEATING. REMAINDER OF THE WEEK
LOOKS DRY PAST TUE AS YET ANOTHER UPR RIDGE BUILDS EAST OVER THE
AREA FROM THE GULF.

&&

.AVIATION...AWW CONDITIONS WITH G35KT VICINITY OF KMCO AND KDAB.
SMALL HAIL (GS) ALSO A CONCERN WITH FREQUENT TO EXCESSIVE LIGHTNING.
THREAT SHOULD DECREASE AFT 21Z. KMLB AND KVRB STILL HAVE OPPORTUNITY
FOR G35KT AS THE AFTERNOON PROGRESSES. ISOLATED AREAS OF OVERNIGHT
4-6SM BR TOWARD 12Z.

&&

.MARINE...SURFACE HIGH PRESSURE WILL BECOME THE MAIN SYNOPTIC
FEATURE OVER THE MARINE AREA SUPPORTING LIGHTER WINDS. SEAS
GENERALLY 1 TO 3 FEET ACROSS THE ENTIRE WATERS THROUGH FRIDAY.
AFTERNOON SEA BREEZE ON FRIDAY TO BRING ONSHORE COMPONENT TO THE
WINDS DURING THE AFTERNOON. A FEW SPECIAL MARINE WARNINGS POSSIBLE
MAINLY ALONG THE TREASURE COAST. SEAS SHOULD BE LESS THAN 3 FT
THROUGH SATURDAY THEN BUILD BEHIND FRONT ON SUNDAY WITH SEAS OF 4
TO 5 FT LATE SUNDAY INTO MONDAY AND DECREASING THROUGH MID WEEK.
