AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 227 PM EDT FRI JUN 20 2014 .SHORT TERM (TONIGHT-SUNDAY NIGHT)... THE WEAK MID/UPPER TROUGH OFF THE FLORIDA EAST COAST ALONG WITH THE WEAK SURFACE TROUGH CONTINUE TO AFFECT THE WEATHER FOR SOUTH FLORIDA. THIS WILL BE THE TREND THROUGH SATURDAY WITH A WESTERLY STEERING FLOW ALSO REMAINING IN PLACE. FORECAST SOUNDINGS DO NOT SHOW STRONG MID LEVEL LAPSE RATES BUT THERE HAS BEEN STRONG DIURNAL HEATING TO GIVE LOW LEVELS AN INCREASED INSTABILITY ALONG WITH PWAT AT 1.9 INCHES SO SOME THUNDERSTORMS COULD BECOME STRONG WITH AN ISOLATED SEVERE WIND GUST ALSO POSSIBLE. THIS APPEARS TO BE A VERY SIMILAR THREAT FOR SATURDAY AFTERNOON WITH PWAT CONTINUING JUST UNDER TWO INCHES. SUNDAY WILL BE A TRANSITIONAL PERIOD TO A DRIER PATTERN WITH THE TROUGH BECOMING ABSORBED WITH ANOTHER UPSTREAM TROUGH THAT WILL MOVE OFF THE MID ATLANTIC COAST. HOWEVER, JUST HOW MUCH OF A DRYING PATTERN IS IN QUESTION NOW. BOTH THE GFS AND NAM SHOW SOME MID LAYER DRYING BUT IT IS NOT SIGNIFICANT AND CONTINUE PWAT AT AROUND 1.7 INCHES. THE GFS IS SHOWING ANOTHER MID LEVEL TROUGH MOVING INTO THE SOUTHERN PLAINS WHICH THEN BEGINS TO LIFT MORE MOISTURE NORTHWARD FROM THE WESTERN CARIBBEAN INTO THE SOUTHEAST GULF OF MEXICO AND DRIES IT OUT SOMEWHAT DURING THE MORNING BUT THEN SHOWS A MOISTURE SURGE IN THE LATE AFTERNOON. IN ADDITION, THE NAM CONTINUES THE WESTERN STEERING CURRENT WHICH WOULD KEEP THE EAST COAST THE MOST ACTIVE BUT THE GFS DEPICTS A MORE SOUTHERLY STEERING FLOW IN RESPONSE TO THE UPSTREAM TROUGH. SO, ALL IN ALL, STILL LOOKS LIKE A FAIRLY ACTIVE PATTERN WITH AT LEAST SCATTERED COVERAGE JUST ABOUT ANYWHERE. .LONG TERM (MONDAY-FRIDAY)... LOOKING INTO NEXT WEEK, THE ATLANTIC RIDGE WILL BUILD BACK TO THE WEST AS THE MID ATLANTIC TROUGH SHIFTS TO THE EAST. THIS WILL ALLOW MID LEVEL WARMING TO OCCUR WITH MEAGER MID LEVEL LAPSE RATES.. AT THE SAME TIME, THE GFS IS SHOWING A SECOND SURGE OF MOISTURE ON TUESDAY AHEAD OF THE TROUGH DEEPENING INTO THE NORTHERN GULF OF MEXICO. HOWEVER, THE ECMWF SHOWS THE SUBTROPICAL RIDGE BECOMING ESTABLISHED ACROSS SOUTH FLORIDA THROUGH THE WEEK WITH A LESSENING THREAT OF THUNDERSTORMS. BUT CONSIDERING THE INSTABILITY THAT IS ALWAYS PRESENT AT THIS TIME OF THE YEAR, SCATTERED ACTIVITY LOOKS LIKE THE PRIMARY THREAT FOR THE WHOLE WEEK. && .MARINE... VERY TRANQUIL BOATING CONDITIONS ARE EXPECTED TO CONTINUE INTO EARLY NEXT WEEK OUTSIDE OF SHOWERS AND THUNDERSTORMS. THERE COULD BE SOME LOCALLY ROUGH SEAS NEAR THE STRONGER CELLS. && .PRELIMINARY POINT TEMPS/POPS...
