NWS Melbourne, FL wrote its last area forecast discussion before the first event at Jul 28, 8:45 AM EST, 5 hours 44 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 945 AM EDT SAT JUL 28 2012 .UPDATE... TODAY...EARLY MORNING CLOUD MOTIONS ON VISIBLE SATELLITE IMAGERY SHOW THAT THE LOW LEVEL RIDGE AXIS HAS CREPT NORTHWARD AND LOOKS TO BE CLOSE TO GRAND BAHAMA/PALM BEACH. AS A RESULT...WEST/SOUTHWEST WINDS ACROSS THE LOCAL AREA HAVE DECREASED SLIGHTLY. THIS WILL ALLOW THE EAST COAST SEA BREEZE TO FORM A LITTLE SOONER. MORNING SOUNDINGS CONTINUE TO SHOW BELOW NORMAL PRECIPITABLE WATER VALUES ACROSS CENTRAL FLORIDA...1.4 TO 1.5 INCHES. GPS DATA IS SIMILAR TO THE SOUNDINGS ACROSS FLORIDA...EXCEPT FOR MUCH LOWER VALUES (AROUND 1 INCH) AT WEST PALM BEACH AND FT LAUDERDALE...WHICH IS CLOSE TO THE DRIER NASSAU SOUNDING. 700 MB TEMPS ARE AROUND 9 CELSIUS EXCEPT ABOUT A DEGREE AND A HALF LOWER AT CANAVERAL. STILL WITH THE RATHER LOW MOISTURE VALUES WE SHOULD NOT SEE EARLY CONVECTIVE INITIATION ALONG THE EAST COAST SEA BREEZE. MAIN CHANCE FOR LATE AFTERNOON AND EVENING STORMS WILL BE OVER FAR INLAND SECTIONS OF THE COASTAL COUNTIES AND ACROSS THE INTERIOR. THE SEA BREEZE WILL BE DELAYED ENOUGH TO BRING THIS SLIGHT CHANCE TO COASTAL VOLUSIA. DO NOT SEE ANYTHING SIGNIFICANT TO CHANGE IN THE CURRENT FORECAST PACKAGE. && .AVIATION... NO CHANGES TO THE PREVIOUS DISCUSSION AS SEA BREEZE GENERATED STORMS LATE THIS AFTERNOON AND EVENING WILL AGAIN HAVE A VERY LOW COVERAGE. KMLB-KSUA MIGHT HEAR THUNDER FROM DISTANT INLAND STORMS. KDAB AND INTERIOR TERMINALS MIGHT HAVE ONE DEVELOP CLOSER...BUT CANNOT PLACE TEMPO GROUPS OR VICINITY THUNDER AT ANY OF THE TERMINALS. THE TIME FRAME FOR THE ISOLATED ACTIVITY SHOULD BE 18-24Z. && .MARINE... TODAY...FAVORABLE BOATING CONDITIONS OCCURRING WITH SOUTH/SOUTHWEST FLOW 10 KNOTS OR LESS. THE SEA BREEZE SHOULD BE GUSTY FOR A FEW HOURS THIS AFTERNOON...WHICH IS LIKELY DUE TO SOME SLIGHTLY COOLER THAN NORMAL SEA SURFACE TEMPERATURES. THE CHANCE FOR AFTERNOON STORMS OVER THE MAINLAND IS LOW AND WESTERLY STEERING LEVEL FLOW LOOKS WEAKER THAN RECENT DAYS. SO OTHER THAN A SLIGHT CHANCE FOR LATE AFTERNOON STORMS AFFECTING THE INTRACOASTAL WATERS...MAINLY NORTH OF THE CAPE...DO NOT FORESEE ANY ADVERSE EFFECTS FROM STORMS ALONG THE COAST OR OVER THE ATLANTIC. && .MLB WATCHES/WARNINGS/ADVISORIES... FL...NONE. AM...NONE. && SHORT TERM/AVIATION...LASCODY IMPACT WEATHER...GLITTO
