AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
325 PM EDT SUN JUN 10 2012

.DISCUSSION...

CURRENT...SPOTTY CONVECTION HAS STARTED DEVELOPING ALONG ECSB WITHIN
THE LAST 90 MINUTES FROM COASTAL VOLUSIA CO SWD TO EAST OF SANFORD-
ORLANDO. ACTIVITY GENERALLY SLOW MOVING...THOUGH STEERING FLOW DOES
FAVOR A SLOW EASTWARD DRIFT. SOME LUMPINESS TO THE CU FIELD ALONG
EASTERN FLANK OF LAKE OKEE BREEZE ACROSS OKEE/WRN MARTIN COS...BUT
NOTHING ON KMLB/KPBI DOWN THERE THUS FAR.

LATE AFTERNOON-TONIGHT...BASED ON CURRENT POSN OF SEA BREEZE BDRYS
EXPECT LATE AFTERNOON COLLISION FROM NEAR LAKE COUNTY SWD TO NEAR
THE 4 CORNERS REGION...AND INTO POLK COUNTY...WITH POTENTIAL FOR
RAPID LATE DAY STORM DEVELOPMENT AGAIN. SOME OF THIS ACTIVITY MAY
DRIFT BACK EWD ACROSS THE NORTHERN CWA...AND AS SUCH HAVE KEPT SMALL
EARLY EVENING POPS THERE. GUSTY WINDS/TORRENTIAL RAINFALL POSSIBLE
AGAIN WITH STORMS THROUGH THIS EVENING.

MON-MON NIGHT...LOW LEVEL RIDGE AXIS DROPS INTO NORTH FLORIDA AS H50
RIDGE CONTINUE TO BUILD OVHD. ORIENTATION OF RIDGE LEADS TO SLIGHT
BACKING OF WINDS AS THEY WEAKEN A TAD. NET RESULT IS THAT THE FCST
DISTRIBUTION OF LATE DAY SHRA/TS LOOK SIMILAR TO TODAY...BUT WITH
EVEN LOWER COVERAGE AS PWATS DROP ANOTHER FEW TENTHS TO 1.6" - 1.8".
HAVE ONLY A 15-20 PCT POP PAINTED FOR THE NORTH AND INTERIOR NEAR
THE KISM RIVER FOR THE AFTERNOON...AND JUST THE FAR NORTH FOR THE
EVENING.

TUE-SUN (PREV)...RIDGE AXIS WILL SLOWLY BE DISPLACED SOUTHWARD
THROUGH THE MID TO LATE WEEK AS A TROF PRESSES INTO THE SE STATES.
THIS WILL GRADUALLY BRING SOME DEEPER MOISTURE BACK INTO THE
AREA...ESPECIALLY NORTH. HAVE INDICATED 40 PCT POPS NORTH/30 CENTRAL
AND 20 SOUTH ON TUE...THEN SCATTERED DAYTIME POPS ALL AREAS FROM
WEDNESDAY ONWARD. STORMS WILL BEGIN TO GAIN A WEAK STEERING
COMPONENT BACK TOWARD THE EAST COAST BY MID WEEK ACROSS NORTHERN
SECTIONS AND PERHAPS FARTHER SOUTH LATE WEEK IF TROF IS ABLE TO SINK
FARTHER SOUTHWARD PER GFS.  DAYTIME HIGHS LOWER 90S INLAND...A FEW
MID 90S AND UPPER 80S/NEAR 90 EAST COAST.

&&

.AVIATION...ONGOING CONVECTION NEAR/NORTH OF KDAB EXPECTED TO WEAKEN
SHORTLY AS ECSB PUSHES WELL WEST. IS APPEARS THE BEST CHANCE FOR A
LATE DAY TS WILL INITIALLY BE NEAR KLEE TO WEST OF KISM ALONG ECSB/
WCSB COLLISION ~22Z WITH POSSIBLE EWD DRIFT BACK TOWARD ISM-MCO-SFB
THROUGH ABOUT 01Z-02Z.

&&

.MARINE...SURFACE RIDGE AXIS TO THE NORTH WILL SLOWLY DRIFT
SOUTHWARD ACROSS THE CENTRAL PENINSULA FROM EARLY TO MID WEEK. THIS
WILL PRODUCE GENERALLY E-SE WINDS AOB 10KT MON/TUE THEN WINDS
BECOMING S-SW AOB 10KT MOST AREAS FROM WED ONWARD AS RIDGE AXIS
DRIFTS SOUTH...WITH ONSHORE COMPONENT DEVELOPING NEAR THE COAST IN
THE AFTERNOONS. SEA HEIGHTS REMAINING AOB 2-3 FT THROUGH THE PERIOD.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
THE EAST AND WEST COAST SEA BREEZES ARE EXPECTED TO COLLIDE OVER
AN AREA FROM NORTHWEST VOLUSIA COUNTY TO WESTERN ORANGE...LAKE
KISSIMMEE ...THEN ALONG THE KISSIMMEE RIVER TO LAKE OKEECHOBEE.
STORM COVERAGE OVER THE WESTERN INTERIOR WILL INCREASE FROM LATE
AFTERNOON INTO THE EARLY EVENING AS THE SEA BREEZE BOUNDARIES
COLLIDE. THE PRIMARY WEATHER HAZARDS WILL BE WIND GUSTS TO 45
MPH...CLOUD TO GROUND LIGHTNING STRIKES AND LOCALLY HEAVY RAIN DUE
TO SLOW ERRATIC STORM MOTION.

.FLOOD IMPACT...
VERY SLOW STORM MOTION WILL MEAN THAT STORMS WILL REMAIN OVER A
SINGLE LOCATION FOR A LONGER PERIOD OF TIME. LOCAL RAINFALL AMOUNTS
OF 1 TO 2 INCHES ARE POSSIBLE...WHICH WOULD PRODUCE VERY SHORT
LIVED FLOODING OF SOME ROADS...LOW SPOTS UNDER BRIDGES AND OVERPASSES
AND IN POOR DRAINAGE AREAS. ANY FLOODING SHOULD QUICKLY DISSIPATE
AS THE DRAINAGE SYSTEMS CATCH UP TO THE BRIEF EXCESSIVE RAINFALL
AMOUNTS.

.MARINE THUNDERSTORM GUST IMPACT...
EARLY AFTERNOON SHOWERS AND STORMS AT THE COAST SHIFT TO THE INLAND
LAKES AND WATERWAYS MID AND LATE AFTERNOON AND INTO THE EARLY
EVENING AS THE SEA BREEZE PUSHES WESTWARD. STORM MOTION WILL BE
ERRATIC...WITH A FEW STORMS DRIFTING BACK TO THE EAST LATE
AFTERNOON AND EARLY EVENING. A FEW STRONG STORMS WILL BE CAPABLE
OF PRODUCING GUSTY WINDS TO 35 KNOTS AND CLOUD TO WATER LIGHTNING
STRIKES.

.RIP CURRENT IMPACT...
OCEAN CONDITIONS WILL PRODUCE AN ELEVATED RISK FOR RIP CURRENTS AT
EAST CENTRAL FLORIDA BEACHES TODAY...CHECK WITH LIFEGUARDS ABOUT
OCEAN HAZARDS WHEN ARRIVING AT THE BEACH. SWIM ONLY WHERE THERE IS
A LIFEGUARD ON DUTY.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
SCATTERED SHOWERS AND STORMS ARE EXPECTED EACH AFTERNOON AS THE
EAST COAST SEA BREEZE DEVELOPS AND MOVES INLAND. STORM CHANCES WILL
INCREASE LATE IN THE WEEK AS ANOTHER WEAK FRONT MOVES INTO NORTH
FLORIDA.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
