NWS Miami, FL wrote its last area forecast discussion before the first event at Oct 6, 1:17 PM EST, 35 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 217 PM EDT SAT OCT 6 2012 .DISCUSSION... THE PRIMARY SYNOPTIC FEATURES OF INTEREST AT THE SURFACE WILL BE THE FRONTAL BOUNDARY THAT WAS ANALYZED EXTENDING SOUTHWEST FROM KENTUCKY TO NORTHERN MS THIS MORNING AND A WEAK HIGH PRESSURE CENTERED NORTHEAST OF THE LOCAL AREA OVER THE WESTERN ATLANTIC. BETWEEN NOW AND MONDAY...SHOWERS AND THUNDERSTORMS ARE FORECAST TO CONTINUE AFFECTING SOUTH FLORIDA, ESPECIALLY OVER THE INTERIOR AND WESTERN SECTIONS. FOR TODAY SHOWERS AND STORMS WILL MOVE VERY SLOWLY AND SOME OF THEM COULD AFFECT THE EAST COAST METRO AREAS. TEMPERATURES ARE FORECAST TO REMAIN MOSTLY UNCHANGED. A FEW AREAS OF PATCHY FOG ARE POSSIBLE OVER THE INTERIOR SECTIONS OF COLLIER, GLADES AND HENDRY COUNTIES AGAIN TONIGHT. LIGHT WINDS AHEAD OF THE FRONTAL BOUNDARY ARE PROVIDING AN ENVIRONMENT THAT IS CONDUCIVE FOG FORMATION OVER THE INTERIOR AND WESTERN PORTIONS OF SOUTH FLORIDA. THE BOUNDARY GETS VERY DIFFUSE AS A WEAK TROUGH OF LOW PRESSURE EAST OF THE BAHAMA ISLANDS MOVES WESTWARD ON MONDAY. THIS IS EXPECTED TO SHIFT THE SURFACE WINDS FROM NORTHEAST TO NORTH BETWEEN MONDAY THROUGH WEDNESDAY. THIS SHIFT IS REFLECTED IN THE LATEST 12Z GFS WINDS. VERY LITTLE CHANGE IN TEMPERATURES IS EXPECTED ALONG THE EAST COAST DUE TO THE FACT THAT THE WINDS WILL STILL PASSING OVER THE GULF STREAM BEFORE THEY REACH THE EAST COAST OF FLORIDA. HOWEVER, THE FLOW WILL BE DRIER IN NATURE AS IT COMES FROM THE CONTINENTAL SURFACE HIGH DEVELOPING OVER THE SOUTHEASTERN US. THIS IS REFLECTED IN THE FORECAST BY A SLIGHT DECREASE IN POPS. FOR TEMPERATURES NO CHANGE IS EXPECTED FOR HIGH TEMPERATURES WITH ONLY A SLIGHT COOLING OF 1 TO 3 DEGREES OVER THE INTERIOR SECTIONS OF GLADES AND HENDRY DUE TO THE MORE NORTHERLY FLOW AND SLIGHTLY LOWER MOISTURE. AS THIS SURFACE HIGH LIFTS NORTH AND NORTHEASTERLY, WINDS ARE EXPECTED TO INCREASE OVER SOUTH FLORIDA BY THURSDAY AS THE HIGH BEHIND THE BOUNDARY EXTENDS OVER THE WESTERN ATLANTIC AND THE FLORIDA PENINSULA. BY THE END OF THE WORK WEEK THE TROUGH OF LOW PRESSURE OVER THE EASTERN US CLEARS THE EAST COAST AND A RIDGE BEGINS TO BUILD OVER THE GULF OF MEXICO. THIS WILL ALLOW FOR SEASONABLE TEMPERATURES ACROSS SOUTH FLORIDA. && .MARINE... LIGHT EASTERLY FLOW WILL PERSIST THROUGH THE WEEKEND AS A FRONTAL BOUNDARY APPROACHES FROM THE NORTH AND NORTHWEST. SCATTERED SHOWERS AND STORMS WILL REMAIN IN THE FORECAST THROUGH THIS TIME AHEAD OF THIS APPROACHING BOUNDARY. DRIER AIR WITH MODERATE NORTH TO NORTHEAST WINDS WILL BECOME A POSSIBILITY THROUGH THE FIRST TO MID HALF OF THE UPCOMING WEEK AS THE FRONTAL BOUNDARY ADVANCES SOUTH INTO THE AREA. THE WINDS ARE EXPECTED TO BECOME MORE NORTHEASTERLY BY THURSDAY. SEAS WILL RESPOND AND INCREASE INTO THE 3 TO 5 FOOT RANGE ACROSS THE ATLANTIC WATERS. HOWEVER, DUE TO THE TEMPORARY SHIFT OF THE WINDS TO THE NORTH, THE GRADUAL INCREASE IN SEAS IS DELAYED TO THURSDAY SINCE THE WINDS DO NOT ACQUIRE A SUFFICIENTLY LONG FETCH ALONG THE SOUTHERN PERIPHERY OF THE HIGH UNTIL THURSDAY. && .AVIATION...(ISSUED 126 PM EDT SAT OCT 6 2012) MODEL GUIDANCE IS INDICATING THAT SHOWERS AND THUNDERSTORMS WILL FORM CLOSER TO THE EAST COAST TAF SITES THIS AFTERNOON AS THE SEA BREEZE MOVES SLOWLY INLAND. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WERE ALREADY FORMING ALONG THE EAST COAST SEA BREEZE. MOST OF THE THUNDERSTORM ACTIVITY WILL LIKELY REMAIN TO THE WEST OF THE TAF SITES CLOSEST TO THE COAST...BUT STILL CLOSE ENOUGH THAT VCTS WAS WARRANTED EVERYWHERE. A LIGHT WESTERLY FLOW ALOFT MAY BRING SOME LIGHT RAIN FROM CIRRUS OUTFLOW BACK TOWARDS THE COAST LATE THIS AFTERNOON INTO THE EVENING HOURS...SO HAVE VCSH FOR THAT POSSIBILITY. OTHERWISE...LIGHT WINDS AND VFR CONDITIONS ARE EXPECTED OVERNIGHT. FOR KAPF...THE GULF COAST SEA BREEZE IS EXPECTED TO PUSH INLAND OVER THE NEXT HOUR. THUNDERSTORMS MAY GET NEAR KAPF AROUND 20Z-00Z BEFORE DIMINISHING DUE TO LOSS OF DAYTIME HEATING. FOG AND/OR LOW CIRRUS REMAINS A POSSIBILITY AT KAPF FROM ABOUT 10-14Z...SIMILAR TO THE LAST COUPLE MORNINGS. LIGHT EASTERLY FLOW AT 10 KNOTS OR LESS IS EXPECTED SUNDAY MORNING THROUGH THE END OF THE TAF PERIOD. && .FIRE WEATHER... DESPITE THE DRIER AIR EXPECTED TO FILTER INTO THE AREA FROM NORTH TO SOUTH NEXT WEEK...RELATIVE HUMIDITIES ARE FORECAST TO REMAIN WELL ABOVE CRITICAL LEVELS WITH NO RED FLAG CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...

FLOODING: TORRENTIAL DOWNPOURS FROM SLOW MOVING STORMS THIS AFTERNOON MAY LEAD TO PONDING OF WATER IN POORLY DRAINED LOCATIONS. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY ISOLATED TO SCATTERED THUNDERSTORMS CAN BE EXPECTED THROUGH THE REMAINDER OF THE HOLIDAY WEEKEND WITH THE MAIN THREATS BEING LIGHTNING, GUSTY WINDS, AND LOCALLY HEAVY RAIN.
