NWS Melbourne, FL wrote its last area forecast discussion before the first event at Jul 7, 2:05 PM EST, 2 hours 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 305 PM EDT SAT JUL 7 2007 .DISCUSSION... TONIGHT/SUNDAY... LATE MORNING CAPE SOUNDING SHOWS -5C AT H5 AND PWATS 1.85...MUCH MORE SIMILAR TO TAMPAS EARLY MORNING SOUNDING. AS DISCUSSED THIS MORNING...ATMOS IS A BIT MORE SUPPRESSED TODAY SO CONVECTION HAS BEEN A LITTLE SLOWER TO GET GOING AND A LITTLE MORE DIFFICULT TO PERSIST. BUT THIS DELAY IN CONVECTIVE INITIATION HAS ALLOWED STRONG HEATING TO OCCUR WITH SOME MID 90S LIKELY ACROSS PORTIONS OF THE INTERIOR. THE WEST COAST SEA BREEZE IS DOMINATING IN W/SW FLOW AND IS SOMEWHAT ACTIVE. EAST COAST SEA BREEZE HAS DEVELOPED AND IS MOVING INLAND SLOWLY. EXPECT AN INCREASE IN COVERAGE AND INTENSITY OF THE SHOWERS AND STORMS AS THEY MOVE E/SE AND INTERACT WITH THE ECSB CLOSER TO THE COAST. PRIMARY THREAT WILL BE FREQUENT AND DANGEROUS CLOUD TO GROUND LIGHTNING AND TORRENTIAL RAINFALL IN THE STRONGER STORMS. STRONG DOWNBURST WINDS ALSO POSSIBLE BUT HAIL IS UNLIKELY. A WEAK BOUNDARY EXTENDING FROM LAKE OKEECHOBEE NE TO THE TREASURE COAST WAS THE FIRST TO SPARK SHOWERS AND STORMS TODAY AND THIS WILL CONTINUE THE REMAINDER OF THE AFTN ACROSS ST LUCIE AND MARTIN. THINK THE BULK OF CONVECTION WILL OCCUR PRIOR TO 8 PM BUT WILL INCLUDE 20% (LAKE) TO 30% (ELSEWHERE) POPS FOR EVENING ACTIVITY TO DIMINISH. && SUN NIGHT-TUE... THE ATLC RIDGE AXIS WILL REESTABLISH ITSELF AS THE PRIMARY WX FACTOR FOR THE FL PENINSULA THRU THE FIRST HALF OF THE UPCOMING WEEK AS THE SHORT WAVE TROF EXTENDING FROM THE LWR MS VALLEY TO NEW ENGLAND SPLITS IN TWO...ABANDONING ITS SRN EXTENSION OVER THE DEEP S AS A WEAK CUTOFF. STRONG ZONAL COMPONENT TO THE H30-H20 JET WILL KEEP THE STORM SYSTEM OVER THE HIGH PLAINS OVER THE NRN TIER STATES AS IT TREKS EWD...THOUGH ITS EXTENSION INTO THE SRN PLAINS SHOULD PICK UP WHATEVER REMAINS OF THE CUTOFF LOW AND PULL IT INTO THE MID ATLC REGION BY 00Z TUE. THE RESULTING S/SERLY STEERING FLOW WILL TAP A RELATIVELY DRY AIRMASS ACROSS THE FL PENINSULA/BAHAMA BANK...WHILE THE DEPARTING CUTOFF LOW WILL PULL RELATIVELY DRY AIR IN FROM THE GOMEX: LATEST RUC ANALYSIS SHOWS THE H100-H70 MEAN RH VALUES OVER THE BAHAMAS/FL STRAITS AND THE GOMEX AOB 70%. STEERING WINDS WILL SHIFT GRADUALLY...SHOULD STILL BE ENOUGH SWRLY COMPONENT ON MONDAY TO CONCENTRATE DIURNAL CONVECTION OVER THE E FL COAST. TRANSITION SHOULD BE MORE NOTICEABLE ON TUE AS THE RIDGE AXIS CREEPS INTO THE SRN CWA...FOCUSING THE HIGHER POPS ALONG THE COAST FROM KVRB NWD. SRLY WINDS AND DECREASED MOISTURE WILL KEEP MAX/MIN TEMPS ABV CLIMO OVER MOST OF THE CWA...THOUGH PORTIONS OF THE IMMEDIATE COAST MAY HOLD IN THE U80 WHERE THE SEABREEZE DEVELOPS EARLY. THU-SAT... ATLC RIDGE EXPECTED TO REMAIN IN THE DRIVERS SEAT WRT TO THE LCL WX PATTERN. THE ZONAL COMPONENT OF THE JET STREAM WILL BE TOO STRONG TO ALLOW THE NEXT WX SYSTEM TO DROP FAR ENOUGH S TO DISRUPT OR DISLODGE THE RIDGE FROM ITS CURRENT POSITION. CLIMO TEMPS/POPS WILL BE THE ORDER THRU THE END OF THE WEEK. && .AVIATION... SCT-NMRS TSRA THROUGH 00Z THEN PATCHY IFR/MVFR VSBYS LATE TONIGHT IN BR/FG. && .MARINE... TRANQUIL CONDITIONS ANTICIPATED THRU THE UPCOMING WEEK AS THE ATLC RIDGE AXIS REESTABLISHES ITSELF AS THE DOMINANT WX FACTOR OVER THE FL PENINSULA. RIDGE AXIS EXPECTED TO MEANDER ACROSS THE CENTRAL PENINSULA...GENERATING A 10-15KT S/SE FLOW ACROSS THE LCL ATLC WATERS THRU MID WEEK...SEAS RUNNING IN THE 2-3FT RANGE. SFC WINDS MAY VEER MORE TO THE S/SW TOWARD THE LATTER HALF OF THE WEEK AS A SHORT WAVE TROF PUSHES OFF THE MID ATLC/NEW ENGLAND COAST. && .MLB WATCHES/WARNINGS/ADVISORIES... FL...NONE. AM...NONE. && SHORT TERM/AVIATION...KELLY LONG TERM....BRAGAW

DEEP TROPICAL MOISTURE COMBINED WITH DAYTIME HEATING AND LOCAL SEA AND LAKE BREEZE BOUNDARY INTERACTIONS WILL RESULT IN ANOTHER AFTERNOON AND EVENING OF NUMEROUS SHOWERS AND LIGHTNING STORMS. WESTERLY STEERING WINDS WILL PUSH ANY ACTIVITY WHICH FORMS OVER THE PENINSULA TOWARD THE EAST AT AROUND 10 MPH....FOCUSING STORM ACTIVITY ALONG THE EAST SIDE OF THE PENINSULA. A FEW STRONGER STORMS COULD PRODUCE BRIEF GUSTY WINDS...HOWEVER THE MAIN THREAT ONCE AGAIN WILL BE CLOUD TO GROUND LIGHTNING AND HEAVY RAINFALL. ...FLOOD IMPACT... RAINFALL AMOUNTS WILL EXCEED TWO INCHES IN SOME LOCATIONS. GIVEN SATURATED GROUND FROM PREVIOUS RAINFALL THIS MAY WILL RESULT IN PONDING OF WATER ON ROADWAYS AND POSSIBLY SOME TEMPORARY INUNDATION OF LOW LYING POORLY DRAINED AREAS. THE THREAT OF STANDING WATER WILL BE FROM THE SAINT JOHNS RIVER EASTWARD TO THE ATLANTIC COAST...DUE TO SEA BREEZE INTERACTION LATE IN THE DAY. ...MARINE THUNDERSTORM GUST IMPACT... THE EASTWARD MOVEMENT OF STORMS WILL CARRY THE ACTIVITY ACROSS THE INTRACOASTAL AND NEAR SHORE ATLANTIC WATERS DURING THE LATE AFTERNOON AND EARLY EVENING. LOCALLY GUSTY WINDS AND ROUGH SEAS WILL OCCUR NEAR THE STRONGEST STORMS...AND THERE IS THE POTENTIAL FOR WATERSPOUTS DUE TO THE VERY MOIST AIR MASS...LIGHT WINDS...AND INTERACTION WITH THE EAST COAST SEA BREEZE. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY. STORM COVERAGE IS EXPECTED TO GRADUALLY DIMINISH EACH DAY FROM SUNDAY ONWARD AS HIGH PRESSURE BUILDS OVER THE STATE.
