SOUTH FLORIDA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 215 PM EDT MON AUG 2 2004 .DISCUSSION...MORNING UPPER AIR CAME IN WITH WARMING ALOFT VERSUS 24 HOURS AGO DUE TO RELEASE OF LATENT HEAT WITH EXTENSIVE ACTIVITY ON SUNDAY. BUT WITH PLENTY OF MOISTURE AND CONTINUED INSTABILITY CONVECTION ONCE AGAIN FIRING UP JUST LATER IN THE DAY. IN RESPONSE TO T.S. ALEX TO OUR NORTH AND UPPER/SURFACE RIDGE TO OUR SOUTH DEEP SOUTHWEST STEERING FLOW CONTINUES TO DOMINATE SOUTH FLORIDA WEATHER. WIDESPREAD RAINFALL TOTALS OF TWO TO FOUR INCHES AND ISOLATED SPOTS IN EXCESS OF FOUR INCHES PROMPTED A FLOOD WATCH FOR TODAY AND THIS EVENING. WE HAVE KEPT THAT GOING AND WILL WAIT TO SEE WHAT ACTUALLY TRANSPIRES THIS PM BEFORE MAKING DECISION WHETHER TO EXTEND OR ALLOW TO EXPIRE AT 00Z. AT ANY RATE, CURRENT THINKING IS THAT ANY FLOODING THAT DOES OCCUR WILL BE LOCALIZED AND ONLY DURING THE AFTERNOON AND EARLY EVENING HOURS. REASONING IS THAT RAINFALL ACROSS THE REGION DURING PAST SEVERAL MONTHS HAS BEEN MUCH BELOW NORMAL WITH WET ACTIVITY ONLY STARTING RECENTLY. FLASH FLOOD GUIDANCE REMAINS AT AROUND 4 TO 6 INCHES FOR A SIX HOUR PERIOD AND THIS WILL ONLY BE ACHIEVED DURING THE PM CONVECTION. OVERALL PATTERN DOES NOT CHANGE THROUGH WEDNESDAY. UPSTREAM TROUGH WHICH WILL BE DIGGING OVER THE SE U.S. WILL PICK UP ALEX DURING THE NEXT 48 HOURS. THIS WILL KEEP DEEP LAYER MOISTURE AND SW FLOW OVER SOUTH FLORIDA THROUGH WEDNESDAY AND THUS HIGH POPS WILL CONTINUE. FOR THE EXTENDED PERIOD, GFS WANTS TO DIG TROUGH AND DRAW DRIER AIRMASS SOUTH. HOWEVER, DEEP LAYER SW FLOW CONTINUES THROUGH SATURDAY SO AGAIN WITH INSTABILITY WOULD SUGGEST SOUTHEAST COAST STILL MOST VULNERABLE. ANOTHER FLY IN THE OINTMENT IS THAT GFS WANTS TO DEVELOP ANOTHER LOW FROM THE WAVE CURRENTLY EAST OF THE LESSER ANTILLES. AS THIS LOW APPROACHES THE BAHAMAS, ANOTHER TROUGH DIGS INTO THE SE U.S. AND BEGINS TO TURN THE LOW TO THE NORTH. THIS BUILDS A RIDGE BETWEEN THE TWO SYSTEMS AND WE BEGIN TO SEE A LOW LEVEL NE FLOW TO DEVELOP SUNDAY AND MONDAY. BUT THIS ENTIRE SCENARIO IS COMPLETELY DEPENDANT ON THE LOW FORMING IN THE FIRST PLACE AND THE GFS IS NOTORIOUS TO SPIN UP NONEXISTENT LOWSN OR AT LEAST TOO FAST. SO SINCE THIS IS DAYS 6 AND 7, WILL HOLD OFF ON MAKING ANY MAJOR CHANGES AND WILL JUST TREND THE POPS DOWNWARD. && .MARINE...WINDS TO REMAIN LESS THAN 15 KT OUT OF THE SW THROUGH THE FORECAST CYCLE SO SEAS WILL REMAIN AT 4 FEET OR LESS. && .FIRE WEATHER...NO CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...
