AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MIAMI FL 1036 AM EDT SAT JUL 7 2007 .UPDATE...LATEST WATER VAPOR IMAGERY ALONG WITH MODEL ANALYSIS FIELDS SHOW THAT SOUTH FLORIDA REMAINS IN BETWEEN TWO MID/UPPER LEVEL RIDGES...WITH ONE LOCATED OVER THE GULF OF MEXICO AND THE OTHER EAST OF THE BAHAMAS. WEAK MID LEVEL TROUGHING IS INDICATED BETWEEN THESE FEATURES. VISIBLE SATELLITE AND SURFACE OBS SHOW CONVERGENCE OVER THE ATLANTIC WATERS THIS MORNING IN RESPONSE TO SOUTHEASTERLY SYNOPTIC FLOW EMERGING ACROSS THE BAHAMAS AND LIGHT OFFSHORE FLOW LATE LAST NIGHT/EARLY THIS MORNING OVER THE FL EAST COAST. THIS CONVERGENCE SHOULD CONTINUE TO WEAKEN AS LAND MASS HEATS UP TODAY AND ALLOWS AN EAST COAST SEA BREEZE TO PROGRESS INLAND...AND THIS IS FURTHER SUPPORTED BY LIGHT SE FLOW ALREADY BEGINNING TO TAKE SHAPE AT SOME EAST COAST OBS POINTS. CUMULUS ARE ALREADY BEGINNING TO DEVELOP RAPIDLY ACROSS THE INTERIOR AND ALSO THE SOUTHERN EVERGLADES THIS MORNING. THE 12Z MIAMI SOUNDING SHOWS PWATS STILL AROUND 2 INCHES ALONG WITH PLENTY OF INSTABILITY. EXPECT SHOWERS TO DEVELOP ACROSS INTERIOR LOCATIONS BY LATE MORNING/NOON HOUR VERY SIMILAR TO LAST SEVERAL DAYS...AND THEN LOOK FOR THUNDERSTORM ACTIVITY TO INCREASE BY EARLY TO MID AFTERNOON AS SEA/LAKE BREEZES DEVELOP AND ENHANCE LOCAL CONVERGENCE. SOUNDINGS SHOW VERY LIGHT SOUTHERLY FLOW IN THE LOW/MID LEVELS...SO ANY STORMS SHOULD BE SLOW MOVERS TODAY AND WILL BE CAPABLE OF PRODUCING VERY LOCALIZED HEAVY RAINFALL...WITH STORM MOTION ORIGINALLY A SLOW NORTHWARD DRIFT BUT EVENTUALLY DETERMINED PRIMARILY BY OUTFLOW PROPAGATION. THIS LIKELY MEANS THE BULK OF THE ACTIVITY WILL STAY INLAND FROM THE EAST COAST METRO AREAS. ALONG THE FL WEST COAST...CUMULUS DEVELOPMENT IS ALREADY UNDERWAY EVEN IN COASTAL COLLIER COUNTY THIS MORNING...AND WITH LIGHT STEERING FLOW EXPECT SHOWERS AND A FEW THUNDERSTORMS TO DEVELOP ACROSS THESE AREAS LATE THIS MORNING/EARLY THIS AFTERNOON BEFORE WEST COAST SEA BREEZE CAN PUSH ACTIVITY INLAND. .AVIATION...FR CONDITIONS ARE EXPECTED OVER ALL TERMINALS THROUGH AT LEAST 18Z...WITH ONLY ISOLD SHRA EXPECTED IN THE VICINITY OF KMIA...KTMB AND KOPF DURING THE LATE MORNING HOURS. AFTERNOON CONVECTION SHOULD AGAIN BEGIN TO DEVELOP AFTER 17Z. EXPECT MOST CONVECTION TO MOVE NORTHWARD UNDER A SOUTHERLY STEERING FLOW AND CONCENTRATE MAINLY ACROSS INTERIOR/LAKE OKEECHOBEE AND VCNTY PBI. MOST MVFR/IFR CONDITIONS TO STAY INLAND TODAY. UPDATE: STRASSBERG AVIATION: GR && .PREV DISCUSSION... /ISSUED 447 AM EDT SAT JUL 7 2007/ DISCUSSION... WHILE A DRIER AIR MASS IS STILL TRYING TO MAKE ITS WAY INTO THE LOCAL REGION...LATEST SATELLITE IMAGERY AND RECENT SUITE OF MODEL GUIDANCE SUGGEST THAT HUMID CONDITIONS WILL CONTINUE ACROSS SOUTH FLORIDA AGAIN TODAY. LOCAL MOISTURE CONVERGENCE CONTINUES ACROSS SOUTH FLORIDA WHILE DRIER AIR IS JUST EAST OF THE BAHAMAS. A SOUTHERLY TO SOUTH SOUTHWESTERLY SURFACE FLOW WILL CONTINUE ACROSS SOUTH FLORIDA TODAY. IN ADDITION A WEAK LOW LEVEL TROUGH WILL CONTINUE TO LINGER JUST OFF THE EAST COAST OF CENTRAL FLORIDA. LATEST GUIDANCE INDICATES MID LEVEL SYNOPTIC SCALE LIFT ACROSS SOUTH FLORIDA THIS AFTERNOON. GIVEN ALL THESE FACTORS CONVECTION SHOULD BE EXPECTED TODAY ACROSS SOUTH FLORIDA...WITH MORE NUMEROUS ACTIVITY ACROSS GLADES...HENDRY AND PALM BEACH COUNTIES...AND MORE SCATTERED IN NATURE ACROSS THE REMAINING COUNTIES. HEAVY SHOWERS CAN BE EXPECTED AGAIN WITH PWATS IN EXCESS OF TWO INCHES FORECAST FOR THIS AFTERNOON. THE GUIDANCE CONTINUES TO SUGGEST THAT THE LOW LEVEL RIDGE AND A DRIER AIR MASS IS EXPECTED TO BEGIN TO BUILD ACROSS SOUTH FLORIDA ON SUNDAY...WITH TIMING VARYING FROM EARLY SUNDAY TO LATE SUNDAY. AT ANY RATE LESS NUMEROUS CONVECTIVE ACTIVITY IS EXPECTED FOR SUNDAY AND DECREASING THROUGH MID WEEK...WITH THE CAVEAT THAT SHOWERS AND THUNDERSTORMS ARE FORECAST TO OCCUR BUT MORE SCATTERED IN NATURE AS COMPARED TO THE ACTIVITY OVER THE LAST FEW DAYS. THERE IS A WEAK TROPICAL WAVE NEAR HISPANIOLA THAT SHOULD HAVE NO IMPACT ON SOUTH FLORIDA AS IT CONTINUES WESTWARD. ANOTHER TROPICAL WAVE IS JUST TO THE EAST OF THE WINDWARD ISLANDS AND THE NORTHERN FRINGE OF THE WAVE MAY BRING LIMITED LOW LEVEL MOISTURE NEAR SOUTH FLORIDA LATE TUESDAY INTO WEDNESDAY. AVIATION... VFR CONDITIONS ARE EXPECTED OVER ALL TERMINALS THROUGH AT LEAST 17Z...WITH ONLY ISOLD SHRA EXPECTED IN THE VICINITY OF KMIA AND KTMB DURING MORNING HOURS. AFTERNOON CONVECTION SHOULD AGAIN BEGIN TO DEVELOP AFTER 17Z. EXPECT MOST CONVECTION TO MOVE NORTHWARD UNDER A SOUTHERLY STEERING FLOW AND CONCENTRATE MAINLY ACROSS INTERIOR/LAKE OKEECHOBEE AND VCNTY PBI. MARINE... TRANQUIL MARINE CONDITIONS EXPECTED ACROSS LOCAL ATLANTIC AND GULF WATERS THROUGH AT LEAST MONDAY. FIRE WEATHER...
