RECENTLY ANIMATED WATER VAPOR LOOP SHOWED A POSITIVELY-TILTED UPPER TROUGH EXTENDING SOUTHWEST OVER THE PLAINS AND A RIDGE AXIS EXTENDING NORTH OVER THE WESTERN ATLANTIC. THIS PLACES SOUTH FLORIDA UNDER PRIMARILY MOIST WEST-SOUTHWEST MID TO UPPER FLOW. WEAK SHORTWAVE TROUGHS EMBEDDED WITHIN THE WSW FLOW COMBINED WITH SUFFICIENT DAYTIME HEATING...INSTABILITY AND DEEP LAYER MOISTURE WILL BE ENOUGH TO TRIGGER CONVECTION ACROSS PORTIONS OF THE LOCAL AREA EACH DAY...ESPECIALLY THROUGH THE AFTERNOON AND EARLY EVENING PERIODS. THE LATEST MODEL GUIDANCE HAS INITIALIZED WELL WITH THIS SYNOPTIC PATTERN AND GENERALLY INDICATES THE LOW-LEVEL FLOW GRADUALLY SHIFTING TO THE SOUTHWEST OVER THE NEXT COUPLE OF DAYS AS A WEAK FRONTAL BOUNDARY APPROACHES FROM THE WEST. THIS SOUTHWEST FLOW COMBINED WITH THE EAST COAST SEA BREEZE WILL LEAD TO THE BEST LOW-LEVEL CONVERGENCE BECOMING ESTABLISHED NEAR AND OVER THE EAST COAST METRO AREAS. AS A RESULT...WILL INDICATE THE HIGHEST RAINFALL PROBABILITIES OVER THESE EAST COAST LOCATIONS THROUGH WEDNESDAY. MODEL PRECIPITABLE WATER VALUES ARE NEARING THE TWO INCH MARK THROUGH THIS TIME WITH THE MAXIMUM VALUES CLOSER TO THESE EAST COASTAL LOCATIONS.
