NWS Miami, FL wrote its last area forecast discussion before the first event at Aug 14, 12:43 PM EST, 1 hour 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 143 PM EDT THU AUG 14 2014 .AVIATION... MORE INSTABILITY TODAY HAS LED TO QUICKER AND STRONGER DEVELOPMENT OF STORMS THROUGH THE INTERIOR THIS EARLY AFTERNOON. MULTIPLE OUTFLOWS ALREADY PRESENT SHOULD SOON INTERACT WITH THE SEA BREEZE NEAR THE DEVELOPING SEA BREEZE AND BEST MOISTURE FOR KFLL/KFXE/KPBI THIS AFTERNOON. OTHER CELLS NOW DEVELOPING JUST SW OF KTMB WILL BE MOVING CLOSE TO KTMB/KMIA/KOPF THE REST OF TODAY. POSSIBLE THAT THESE STORMS LAST A LITTLE DEEPER INTO THE EVENING THAN USUAL...WITH A SOMEWHAT GREATER LIKELIHOOD OF BRIEF IFR CONDS UNDER THE STRONGEST STORMS. EXPECTING SIMILAR COVERAGE FOR FRIDAY. && .PREV DISCUSSION... /ISSUED 1028 AM EDT THU AUG 14 2014/ UPDATE... UPDATED THE FORECAST FOR THE SHORT TERM BUT NO DRASTIC CHANGES. THE FORECAST FOR THE AFTERNOON PERIOD STILL CONTAINS SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS BUT MAINLY FOCUSED IN THE NORTHERN AND EASTERN PORTIONS OF THE PENINSULA. THE FACTORS LEADING TO THIS FORECAST INCLUDE A WEAKENING UPPER LEVEL RIDGE AS AN UPPER LEVEL TROUGH CONTINUES TO DEEPEN INTO THE SOUTHEAST U.S. IN ADDITION THE REGIONAL SOUTHWESTERLY WINDS SHOULD FAVOR SURFACE CONVERGENCE THIS AFTERNOON IN THE EASTERN HALF OF THE PENINSULA. LASTLY THE LATEST MESO-SCALE MODEL GUIDANCE IS IN AGREEMENT WITH THIS SCENARIO WITH CONVECTION CONCENTRATED IN THE LAKE REGION AND ALONG THE EASTERN HALF OF THE PENINSULA THIS AFTERNOON AND EARLY EVENING. ALSO NOTEWORTHY ARE THE CLOUD CONVERGENCE LINES ACROSS THE REGIONAL WATERS AND LIGHTER WINDS IN THE LOWER LEVELS. THESE CONDITIONS FAVOR WATERSPOUT DEVELOPMENT. 60 PREV DISCUSSION... /ISSUED 817 AM EDT THU AUG 14 2014/ AVIATION... SLIGHTLY MORE INSTABILITY BROUGHT BY COOLER H5 TEMPS AND A CONTINUATION OF A SSE SEA BREEZE ALONG THE ATLANTIC COAST...SHOULD LEAD TO MORE NUMEROUS STORMS TODAY. SHOWERS HAVE FIRST DEVELOPED JUST NORTHWEST OF A KTMB/KMIA AROUND NOON WITH THE SEA BREEZE THE PAST FEW DAYS...AND THIS MAY HAPPEN AGAIN. PERHAPS ANY OUTFLOWS FROM THIS EARLIER DEVELOPMENT WILL BE MORE EFFECTIVE WITH REGARDS TO SPAWNING ADDITIONAL STORMS THAN YESTERDAY. ONCE AGAIN EXPECTING...MAINLY MORNING SHOWERS WITH POSSIBLY SOME EMBEDDED THUNDER AT KAPF. ALTHOUGH KPBI MAY BE THE LAST TO OBSERVE THUNDER LATER TODAY...IT MAY END UP BEING THE MOST ACTIVE TERMINAL. BECAUSE OF THE ABOVE AND CURRENT POP FORECAST...HAVE INSERTED TEMPO TSRA GROUPS THIS AFTERNOON. PREV DISCUSSION... /ISSUED 403 AM EDT THU AUG 14 2014/ DISCUSSION... MOISTURE PLUME CONTINUES OVER THE GULF OF MEXICO ALONG AND SOUTH OF A FRONTAL BOUNDARY DRAPED ACROSS NORTH FLORIDA. THE SOUTHERN EXTENT OF THE MOISTURE PLUME WAS ACROSS THE LOCAL EASTERN GULF WATERS TOWARD THE LAKE REGION...WITH DRIER AIR OVER THE SOUTHEASTERN HALF OF THE REGION AND INTO THE ATLANTIC WATERS AND BAHAMAS. A FEW SHOWERS WERE DEVELOPING ONCE AGAIN ACROSS THE LOCAL GULF WATERS AND MOVING INTO COLLIER COUNTY EARLY THIS MORNING. DEEP LAYER SOUTHWESTERLY FLOW WILL CONTINUE ACROSS THE REGION TODAY AROUND HIGH PRESSURE LOCATED ACROSS THE NORTHERN KEYS. COLDER TEMPS ALOFT (-7 TO -8C AT 500MB) OVER THE GULF OF MEXICO WILL BEGIN TO ADVECT INTO THE REGION TODAY AND ESPECIALLY FRIDAY. THIS WILL STEEPEN THE MID LEVEL (700-500MB) LAPSE RATES TO -6 TO -6.5 C/KM. THIS WILL ALLOW FOR MORE NUMEROUS CONVECTION TODAY AND FRIDAY...AND SOME STRONGER STORMS. INITIAL ACTIVITY IS FORECAST TO DEVELOP IN THE DEEPER MOISTURE ACROSS THE LAKE REGION...WITH NUMEROUS SHOWERS AND STORMS DEVELOPING ALONG THE EAST COAST SEA BREEZE IN THE AFTERNOON...ESPECIALLY FROM NORTHEASTERN MIAMI-DADE NORTHWARD. LOCALLY HEAVY RAIN AND ISOLATED STREET FLOODING IS ALSO POSSIBLE. TEMPERATURES WILL BE HOT TODAY WITH HIGHS IN THE LOW TO MID 90S. SIMILAR CONDITIONS ARE EXPECTED ON FRIDAY...EXCEPT THE RIDGE AXIS WILL SHIFT SLIGHTLY NORTHWARD...AND THE BEST CHANCES FOR RAIN WILL SHIFT TO CENTRAL BROWARD COUNTY NORTHWARD AS WELL. THE DEEP LAYERED RIDGE WILL REMAIN ACROSS SOUTH FLORIDA THROUGH THE WEEKEND...BUT DRIER AIR AND EVEN SOME SAL IS FORECAST TO PUSH WEST ACROSS THE BAHAMAS AND INTO THE SOUTH FLORIDA...ESPECIALLY ON SUNDAY. THIS MAY LIMIT OVERALL THUNDERSTORM CHANCES...BUT ANY STORMS THAT DEVELOP MAY BE CAPABLE OF PRODUCING STRONG WIND GUSTS. DRY AIR AND SAL MAY CONTINUE ACROSS THE REGION ON MONDAY AHEAD OF A TROPICAL WAVE...WITH MINIMAL ACTIVITY ACROSS SOUTH FLORIDA. THE RIDGE WILL BEGIN TO LIFT NORTH OF THE REGION EARLY NEXT WEEK...WITH EASTERLY FLOW RETURNING. GUIDANCE IS IN RELATIVELY GOOD AGREEMENT ON THE NORTHERN PORTION OF A TROPICAL WAVE TRAVERSING SOUTH FLORIDA BEGINNING AS EARLY AS MONDAY NIGHT AND CONTINUING THROUGH WEDNESDAY...WITH MUCH HIGHER RAIN CHANCES ACROSS THE REGION. HIGH AND LOW TEMPERATURES ARE FORECAST TO BE WITHIN A COUPLE DEGREES OF NORMALS EACH DAY. AVIATION... VFR CONDITIONS SHOULD PREVAIL THROUGH THE BULK OF THE MORNING TODAY WITH LIGHT SSW WINDS. SLIGHTLY BETTER AFTERNOON SHRA/TSTM COVERAGE WILL BE POSSIBLE TODAY DUE TO AN INCREASE IN MOISTURE AND INSTABILITY COMPARED TO THE PAST FEW DAYS. THE BEST CHANCE FOR SHOWERS WILL REMAIN ALONG THE GULF COAST/SITE APF THROUGH THE MORNING PERIOD BEFORE SHIFTING TO THE INTERIOR AND EAST COAST AREAS THROUGH THE AFTERNOON HOURS. WINDS ALONG THE ATLANTIC COAST WILL SHIFT TO THE SSE AS THE EAST COAST SEA BREEZE DEVELOPS AND BEGINS TO PUSH INLAND. KEPT VCTS ALONG THE EAST COAST THROUGH THE AFTERNOON HOURS TO ACCOUNT FOR THIS ENHANCED POSSIBILITY. MARINE... SOUTH TO SOUTHWEST WINDS GENERALLY AROUND 10 KNOTS OR LESS ARE FORECAST TO PREVAIL THE REMAINDER OF THE WEEK AND INTO THE UPCOMING WEEKEND WITH WAVE HEIGHTS GENERALLY TWO FEET OR LESS DURING THIS PERIOD. && .PRELIMINARY POINT TEMPS/POPS...
