AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 150 PM EDT FRI JUL 4 2014 .AVIATION... SCATTERED TSRA ALREADY UNDERWAY AND THIS TREND WILL CONTINUE AS THE AFTERNOON PROGRESSES. SEA BREEZE WELL INLAND FROM THE MIAMI- DADE TERMINALS SO DELAYED VCTS FOR KOPF, KMIA AND KTMB UNTIL 20Z WHEN SOME OF CONVECTION COULD MOVE BACK TOWARDS THOSE TERMINALS IN THE NORTHEAST STEERING FLOW. THERE COULD BE SOME BRIEF MVFR/IFR CONDITIONS IF A TSRA MOVES NEAR THE TERMINAL BUT ONLY PLACED THE VCTS FOR NOW WITH SIMILAR CONDITIONS EXPECTED SATURDAY AFT 15Z. KOB && .PREV DISCUSSION... /ISSUED 1024 AM EDT FRI JUL 4 2014/ UPDATE... THERE WERE SOME CHANGES MADE TO THE SHORT TERM FORECAST FOR THIS AFTERNOON AND EARLY EVENING. THE FORECAST FOR THE EAST COAST METRO AREAS WAS UPDATED TO INCLUDE SCATTERED AFTERNOON/EARLY EVENING SHOWERS/THUNDERSTORMS. THE 12Z SOUNDING INDICATED A PWAT OF AROUND 1.9 INCHES. IN ADDITION THERE ARE LOW LEVEL SOUTHWESTERLY WINDS AND MID LEVEL WESTERLY WINDS. WITH THE EAST AND WEST COAST SEA BREEZES EXPECTED TODAY...INITIATION OF CONVECTION IS EXPECTED IN THE INTERIOR PORTIONS OF THE PENINSULA. BUT LATER IN THE AFTERNOON THE AFOREMENTIONED WESTERLY WINDS COULD HELP TO SHIFT SHOWERS/THUNDERSTORMS TOWARDS THE ATLANTIC COASTAL ZONE. THE LATEST GUIDANCE...INCLUDING THE LATEST HRRR MODEL...SUGGESTS THIS TREND AS WELL. SO SCATTERED SHOWERS/THUNDERSTORMS WERE ADDED TO THE ATLANTIC COAST METRO AREAS BUT MAINLY EXPECTED LATE AFTERNOON AND EARLY EVENING. THE 12Z SOUNDING ALSO INDICATED SOME LAYERS OF DRIER AIR IN THE MID LEVELS AND IN THE HAIL GROWTH ZONE SO SMALL HAIL IS POSSIBLE WITH THE STRONGER THUNDERSTORMS. IN ADDITION THERE COULD BE A SLIGHT RISK OF WATERSPOUTS ACROSS THE ATLANTIC WATERS AS THE LOW LEVEL WIND PROFILE IS FAVORABLE. 60 PREV DISCUSSION... /ISSUED 759 AM EDT FRI JUL 4 2014/ AVIATION... MOSTLY VFR IS EXPECTED TODAY WITH SCT TSRA AFT 19-20Z THIS AFTERNOON. LIGHT FLOW WILL GIVE WAY TO SEA BREEZES ALONG BOTH COASTS AROUND 17Z WITH CONVECTION DEVELOPING ALONG THE BOUNDARIES. THE STEERING FLOW IS ERRATIC THIS MORNING AND FORECAST SOUNDINGS SHOW SIMILAR CONDITIONS THROUGHOUT THE DAY. THUS, TSRA MOVEMENT WITH INTERACTIONS BETWEEN BOUNDARIES WILL BE SLOW AND ERRATIC SO ONLY PLACED VCTS IN THE FORECASTS AT THIS TIME BUT THERE COULD BE A BRIEF MVFR/IFR CIG/VSBY FAVORING THE EAST COAST TERMINALS AND WILL AMEND IF NECESSARY. KOB PREV DISCUSSION... /ISSUED 348 AM EDT FRI JUL 4 2014/ DISCUSSION... THE WEATHER PATTERN ACROSS SOUTH FLORIDA WILL BE INFLUENCED BY WEAK LOW PRESSURE TO THE NORTH. THIS WILL KEEP WEAK INSTABILITY OVER THE AREA FOR TODAY. GIVEN THE NOCTURNAL ACTIVITY OF TONIGHT, WILL KEEP SHOWERS AND THUNDERSTORMS IN THE FORECAST THROUGH THE DAY TODAY. LOOKING AT MODEL WINDS, THE STEERING FLOW IS FROM THE SOUTHWEST. IT DOES APPEAR THAT A GULF BREEZE WILL DEVELOP, TURNING THE WINDS SOMEWHAT MORE WESTERLY THIS AFTERNOON, FOR THE WESTERN HALF OF THE CWA. THE ATLANTIC SEA BREEZE SHOWS UP, BUT VERY WEAK AND DOES NOT LOOK AS THOUGH IT WILL BE ABLE TO PENETRATE TOO FAR INLAND, MOST LIKELY DUE TO THE SW FLOW. THIS MAKES THE BETTER CONVERGENCE AREA TO BE IN THE INTERIOR, WITH THE WESTERN INTERIOR AREAS OF BROWARD, PALM BEACH, AND MIAMI DADE COUNTIES, AS WELL AS THE EASTERN AREAS OF COLLIER, GLADES, AND HENDRY COUNTIES. HOWEVER, AS WITH MOST AFTERNOONS IN SOUTH FLORIDA, CAN NOT RULE OUT ANY LOCATION ACROSS THE AREA FOR SHOWERS AND THUNDERSTORMS THIS AFTERNOON. AS FOR THEIR INTENSITY, YESTERDAY LOOKED SOMEWHAT BETTER. TODAY, THE 500MB TEMP IS -6.8C. THE 700-500MB LAPSE RATE IS RIGHT AROUND 6 C/KM. THE NCAPE IS AROUND .15 AND CAPE IS LESS THAN 2000 JOULES. SO,. THIS ADDS UP TO MAINLY GARDEN VARIETY THUNDERSTORMS TODAY. THERE IS A DRY LAYER IN THE MID LEVELS THAT COLD HELP BRING A FEW STRONG DOWNBURSTS WITH ANY THUNDERSTORM THAT DEVELOPS. HOWEVER, ONLY EXPECTING DOWNDRAFTS OF 40-50 MILES PER HOUR AT THIS TIME. THE FREEZING LEVEL IS AROUND 15000, WHICH MAKES HAIL DIFFICULT, AND IF IT DOES FORM, IT SHOULD KEEP IT ON THE SMALL SIDE. AFTER TODAY, HIGH PRESSURE BEGINS TO BUILD TO THE EAST. THIS WILL TURN THE FLOW MORE TO THE SOUTHEAST TO EAST. WITH THIS CHANGE, MORE OF THE CONVECTIVE ACTIVITY WILL SHIFT FROM THE EASTERN INTERIOR, TO THE WESTERN INTERIOR AND GULF COAST. THIS WILL PERSIST WITH AFTERNOON SHOWERS AND THUNDERSTORMS IN THE AFORE MENTIONED AREA EACH AFTERNOON. IN THE OVERNIGHT HOURS, THERE WILL BE SOME MARITIME SHOWERS AND THUNDERSTORMS OVER THE ATLANTIC. SOME OF THESE MAY MAKE THEIR WAY ONSHORE, THE DISSIPATE OVER THE ATLANTIC METRO AREAS. AS THE WEEK PROGRESSES, AN UPPER LEVEL HIGH WILL DEVELOP AND STRENGTHEN OVER THE WESTERN ATLANTIC. THIS WILL KEEP THE EAST TO SOUTHEASTERLY FLOW OVER THE AREA, AS WELL AS, KEEP MOISTURE OVER SOUTH FLORIDA. THIS WILL KEEP SHOWERS AND THUNDERSTORMS IN THE FORECAST THE THE ENTIRE FORECAST PERIOD. AVIATION... A LINE OF ISOLATED SHOWERS AND THUNDERSTORMS STRETCH ACROSS THE ATLANTIC WATERS SOUTHWEST TO THE GULF WATERS. SOME OF THIS ACTIVITY MAY APPROACH KAPF AND KPBI OVER THE NEXT COUPLE OF HOURS BEFORE DISSIPATING...ALTHOUGH LEFT ANY VICINITY MENTION OUT OF TAFS FOR NOW. FOR THE REMAINDER OF THE PERIOD...DELAYED THE ONSET OF CONVECTION ACROSS THE EAST COAST SITES UNTIL 20Z AS MODEL REFLECTIVITIES DEPICT CONVECTIVE INITIATION MAINLY ACROSS THE INTERIOR. MARINE... WITH HURRICANE ARTHUR MOVING AWAY, MARINE CONDITIONS SHOULD CONTINUE TO IMPROVE. THERE WILL BE A 1 FOOT SWELL THROUGH THE DAY TODAY. THERE ALSO MAY BE SHOWERS AND THUNDERSTORMS ACROSS ALL SOUTH FLORIDA WATERS, MAINLY IN THE OVERNIGHT HOURS, FOR THE FORESEEABLE FUTURE. && .MFL WATCHES/WARNINGS/ADVISORIES... FL...NONE. AM...NONE.
