AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 316 PM EDT TUE JUL 14 2015 .DISCUSSION... STORMS HAVE ALREADY DEVELOPED ALONG THE EAST COAST AND WESTERN SUBURBS, AS CONVERGENCE DEVELOPS BETWEEN SOUTHWEST FLOW AND THE DEVELOPING EAST COAST SEA BREEZE. HIGHER CHANCES FOR SHOWERS AND STORMS ALONG THE EAST COAST SHOULD CONTINUE THROUGH AT LEAST THURSDAY, WITH A SIMILAR WIND PROFILE EXPECTED. A FEW STORMS COULD BE STRONG ALONG THE EAST COAST THIS AFTERNOON WITH VERY HEAVY RAIN, AS THEY CONGLOMERATE AND SLOW AS THEY NEAR THE BEACHES. A FEW STRONG STORMS WILL BE POSSIBLE EACH DAY ACROSS EASTERN SECTIONS THROUGH THE END OF THE WEEK. GFS H7-H5 LAPSE RATES ARE SLIGHTLY MORE STEEP ACROSS PALM BEACH COUNTY FOR WEDNESDAY, WHICH COULD MAKE STRONGER STORMS A LITTLE MORE PROBABLE. IN ADDITION, ALTHOUGH WEAKENING, A DISTURBANCE WILL BE SINKING INTO THE LAKE REGION LATER WEDNESDAY. MID LEVEL TROUGH BISECTING ARKLATEX AND WESTERN ATLANTIC H5 HIGH PRESSURE, RESPONSIBLE FOR THE SOUTHWESTERLY FLOW, WILL LIFT NORTH INTO FRIDAY, AS HEIGHTS RISE ALONG THE FLORIDA AND SOUTHEAST COAST. SURFACE FLOW WILL VEER MORE TO THE SOUTH, PLACING THE HIGHEST POPS ALONG THE INTERIOR. SOMEWHAT DRIER AIR THROUGH THE MIDLEVELS WILL ALSO ARRIVE ALONG THE EAST COAST. ALTHOUGH SHOWERS AND STORMS WILL REMAIN IN THE FORECAST FOR THE EAST COAST, THEY SHOULD BE LESS NUMEROUS THIS WEEKEND COMPARED TO THE NEXT FEW DAYS. THE GFS AND THE ECMWF ARE IN DISAGREEMENT REGARDING THE STRENGTH OF A MIDLEVEL SHORTWAVE WHICH MAY MOVE THROUGH CENTRAL FLORIDA ON SUNDAY. IF THE GFS IS CORRECT, SUNDAY WOULD BE THE WETTER OF THE TWO WEEKEND DAYS. AT THE END OF THE FORECAST, A TROUGH MAY AGAIN RETURN TO THE EASTERN CONUS, WITH WEAK SOUTHWESTERLY WINDS RETURNING AND STORMS FOCUSING ONCE AGAIN ALONG THE EAST COAST. && .AVIATION... A GENERALLY SOUTHWESTERLY WIND FLOW PREVAILS ACROSS THE REGION. BUT RECENT SATELLITE IMAGERY...DOPPLER RADAR RETURNS AND REGIONAL OBSERVATIONS INDICATE THE EAST COAST SEA BREEZE TRYING TO BECOME ESTABLISHED WITH SHOWERS/THUNDERSTORMS IN VICINITY OF KMIA AND KOPF AND INTERIOR PENINSULA. FOR THE INTERIOR ATLANTIC COAST TERMINALS THE SEA BREEZE MAY NOT PENETRATE THAT FAR INLAND BUT MAY HAVE TO BE AMENDED IF IT DOES. COVERAGE OF SHOWERS/THUNDERSTORMS EXPECTED TO BE GREATEST EASTERN PENINSULA AND VICINITY OF EAST COAST TERMINALS WITH BRIEF PERIODS OF MVFR TO NEAR IFR CONDITIONS POSSIBLE AT THE TERMINALS WITH OCCURRENCE OF SHOWERS/THUNDERSTORMS...MAINLY 18Z TO ABOUT 23Z. && .MARINE... TROUGH ALONG THE EASTERN SEABOARD, ALTHOUGH LIFTING NORTH BY THE END OF THE WEEK, WILL DELIVER SOUTH TO SOUTHWESTERLY FLOW AT AROUND 10 KNOTS. WINDS VEER TO THE SOUTH AND SOUTHEAST BY THIS WEEKEND. SEAS OF ONLY 1-2 FEET CAN BE EXPECTED. CHANCES FOR SHOWERS AND THUNDERSTORMS WILL PREVAIL EACH DAY ACROSS THE WATERS WITH LOCALLY HIGHER WINDS AND SEAS. && .PRELIMINARY POINT TEMPS/POPS...
