AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 200 AM EDT SUN AUG 12 2001 00Z MFL SOUNDING CONTINUES TO SHOW VERY WEAK FLOW IN THE LOWER LEVELS... IN FACT ALL THE WAY THROUGH THE MID LEVELS. AVERAGE WIND SPEED AT 00Z WAS AROUND 3 KNOTS UP FROM THE SURFACE TO 600 MB. HOWEVER... MODELS SEEM TO INDICATE A SLIGHT NORTHWARD DRIFT OF THE SURFACE RIDGE AXIS SO LOW LEVEL EASTERLIES MAY INCREASE JUST EVER SO SLIGHTLY TODAY. AGAIN EXPECT A REPEAT WITH MOST OF THE TSTORMS FORMING INLAND ALONG THE SEA BREEZE COLLISIONS... AND WITH LITTLE MEAN STEERING TSTORM OUTFLOWS SHOULD BE THE MAIN MECHANISM FOR REGENERATION (MUCH LIKE SATURDAY WAS). WILL AGAIN MENTION TSTORMS MAINLY WESTERN SUBURBS FOR METRO AREAS TODAY. MODELS DO INDICATE SUBTLE CHANGES COMING HOWEVER. BY MONDAY... THE UPPER RIDGE ACROSS FLORIDA BEGINS TO BREAK DOWN AS A MAJOR TROUGH DEVELOPS AND DEEPENS OVER THE EASTERN HALF OF THE COUNTRY. THIS COMBINED WITH THE SURFACE RIDGE WEAKENING AND A WEAK TROPICAL WAVE PASSING JUST TO THE SOUTH OF SOUTH FLORIDA ON MONDAY... SHOULD LEAD TO SOME INCREASE IN PRECIPITATION OVER EVEN THE METRO AREAS. CURRENT FORECAST COVERS THIS WELL AND WILL MAKE ONLY VERY SLIGHT CHANGES. FOR THE MARINE... LIGHT WIND AND SLIGHT SEAS WILL CONTINUE THROUGH THE REGULAR AND EXTENDED FORECAST PERIODS WITH NO LARGE CHANGES IN THE SLACK PRESSURE GRADIENT ENVISIONED ANYTIME SOON. EXTENDED-WISE SEE LITTLE CHANGE. LIGHT FLOW WITH SEA BREEZES ALONG BOTH COASTS PREDOMINATING... WITH POPS BEING MOST AFFECTED BY ANY PASSING TROPICAL WAVES. EXCEPT FOR THE ONE THAT EVENTUALLY BECAME BARRY THESE WAVES HAVE ALL BEEN WEAK AND DISORGANIZED... AND THAT TREND LOOKS LIKE IT WILL CONTINUE.
