AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 237 PM EDT SAT MAY 19 2012 .SHORT TERM...TONIGHT THROUGH TUESDAY...A BROAD MID TO UPPER TROUGH CONTINUES TO EXTEND FROM THE MID ATLANTIC REGION SOUTHWEST TO NORTH-CENTRAL PORTIONS OF THE GULF OF MEX. AT THE SAME TIME...A WEAK LOW LEVEL TROUGH CONTINUES TO EXTEND FROM A DISTURBANCE JUST OFF THE CAROLINAS SOUTHWEST TO SOUTH CENTRAL FLORIDA. NEITHER ONE OF THESE FEATURES IS EXPECTED TO MOVE MUCH THROUGH AT LEAST TUESDAY. THIS WILL CONTINUE TO RESULT IN UNSETTLED WEATHER CONDITIONS. GOOD UPPER LEVEL DYNAMICS COUPLED WITH DIURNAL HEATING AND LOCAL SEA/LAKE BREEZES WILL LEAD TO DAILY AFTERNOON TSTMS THROUGH THIS PERIOD. ALTHOUGH CONVECTIVE ACTIVITY CAN BE EXPECTED OVER ANY PORTION OF SOUTH FLORIDA...A WESTERLY STEERING FLOW WILL TEND TO FAVOR STORMS MOVEMENT MORE TOWARD EASTERN INTERIOR AND EAST COAST. .LONG TERM...WEDNESDAY THROUGH SATURDAY...THE UPPER TROUGH SHOULD BEGIN TO LIFT NORTHEAST AND BE REPLACED BY AN UPPER RIDGE. MODERATE SUBSIDENCE ASSOCIATED WITH THIS RIDGE SHOULD LEAD TO SLIGHTLY DRIER CONDITIONS THROUGH THIS PERIOD. PREVIOUS GFS RUNS WERE INDICATING A DISTURBANCE IN THE LOW LEVEL EASTERLIES OVER THE WESTERN CARIBBEAN WITH THE NORTHERN EDGE MOVING ACROSS S. FLORIDA THURSDAY THROUGH SATURDAY. HOWEVER...LATEST RUNS ARE NOT AS AGGRESSIVE AND NOW KEEP MOST OF THE PRECIP SOUTH OF THE LOCAL AREA. IN VIEW OF THIS...WL GO CLOSE TO CLIMO AND KEEP LOW SCT POPS THROUGH THIS PERIOD. && .MARINE...SFC WINDS SHOULD REMAIN MOSTLY EAST AND REMAIN LIGHT THROUGH THE MIDDLE OF NEXT WEEK. A SMALL NE SWELL SHOULD BEGIN TO AFFECT THE ATLANTIC WATERS FROM SUNDAY ON. && .FIRE WEATHER...NO PROBLEMS EXPECTED. && .PRELIMINARY POINT TEMPS/POPS...
