NWS Miami, FL wrote its last area forecast discussion before the first event at Jul 23, 8:47 AM EST, 3 hours 43 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 947 AM EDT WED JUL 23 2014 .UPDATE... PLAN TO MAKE SOME ADJUSTMENTS TO THE POPS OVER AT LEAST THE INTERIOR AS THEY SEEM A BIT HIGH BASED ON CURRENT TRENDS. WATER VAPOR IMAGERY AND THE 12Z MFL SOUNDING BOTH SHOW SIGNIFICANT DRYING HAS OCCURRED ABOVE THE 500MB LEVEL. HOWEVER, THE LOW LEVELS REMAIN QUITE MOIST WITH A PWAT OF JUST UNDER 2 INCHES AND WITH DIURNAL HEATING BEGINNING IN EARNEST THIS MORNING ALREADY HAVE CONVECTION FIRING ACROSS THE EAST COAST METRO REGION. LOOKING AT THE CONVECTIVE PARAMETERS, THE CAPE IS OVER 2000 J/KG, 500MB TEMPERATURE WARMED TO 4.7C AND THE MID LEVEL LAPSE RATE IS NEAR 5.5C/KG. WITH THE EXCEPTION OF THE CAPE AND THE PWAT, THESE NUMBERS ARE VERY UNIMPRESSIVE AND BELOW THE AVERAGE FOR MID/LATE JULY. STILL, IT SEEMS THE HIGH PWAT AND CAPE ALONG WITH STRONG DIURNAL HEATING WILL SOMEWHAT COUNTERACT THE OTHER LOW CONVECTIVE ELEMENTS. THE HRRR HAS BEGUN TO SHOW LESS OVERALL COVERAGE OVER THE INTERIOR FOR THIS AFTERNOON THAN THE 70-80% ORIGINALLY ADVERTISED, SO WITH THE LESS THAN AMPLE PARAMETERS WILL ONLY LOWER THE POPS SLIGHTLY UNTIL LATER TRENDS DICTATE OTHERWISE. KOB && .PREV DISCUSSION... /ISSUED 740 AM EDT WED JUL 23 2014/ AVIATION... HIGH PRESSURE IS SLOWLY BEGINNING TO BUILD OVER THE AREA FROM THE EAST. THIS WILL KEEP A SOUTH TO SOUTHEAST FLOW OVER SOUTH FLORIDA. THIS WILL ALSO HELP TO PUSH SHOWERS AND THUNDERSTORMS INTO THE INTERIOR BY THE EARLY AFTERNOON. DID KEEP VCTS IN THE TAFS UNTIL AROUND 10Z FOR THE EASTERN TAF LOCATIONS. KAPF MAY SEE A LONGER DURATION OF IMPACT FROM CONVECTION, SO KEPT THE VCTS IN UNTIL 23Z. SO, GENERALLY VFR CONDITIONS WITH BRIEF IFR POSSIBLE DUE TO ANY SHOWERS AND OR THUNDERSTORMS THAT MOVE OVER THE TAF SITES. THE WIND WILL GO LIGHT AND VARIABLE ONCE AGAIN, BY LATE EVENING. PREV DISCUSSION... /ISSUED 400 AM EDT WED JUL 23 2014/ SYNOPSIS... SLIGHT DRIER AIR WILL MOVE INTO THE AREA THIS AFTERNOON AND TONIGHT...AS HIGH PRESSURE BUILDS IN. THIS HIGH PRESSURE WILL DOMINATE SOUTH FLORIDA WEATHER AT LEAST INTO EARLY NEXT WEEK. SHORT TERM /TODAY THROUGH FRIDAY/... HIGH PRESSURE CENTERED NORTH AND EAST OF THE BAHAMAS WILL GRADUALLY STRENGTHEN TODAY...WITH DRIER AIR SPILLING NORTHWARD INTO SOUTH FLORIDA THIS AFTERNOON AND TONIGHT. STILL PLENTY OF MOISTURE FOR SEA-BREEZE TO INDUCE SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS...BUT COVERAGE WILL BE LESS THAN PREVIOUS FEW DAYS...ESPECIALLY OVER EAST COAST URBAN AREAS WHERE DRY AIR WILL BE FIRST TO REACH. THIS DRIER THAN NORMAL AIRMASS WILL REMAIN OVER SOUTH FLORIDA THROUGH THE SHORT TERM...AS RIDGE AXIS ORIENTS OVER THE PENINSULA. RAIN CHANCES WILL BE LOWER THAN NORMAL BOTH THURSDAY AND FRIDAY...AND SHOULD BE MOSTLY FOCUSED OVER THE INTERIOR WHERE SEA-BREEZES INTERACT. LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... DEEP LAYER RIDGE WILL STRENGTHEN FURTHER OVER THE WEEKEND. SCATTERED DAYTIME SHOWERS AND THUNDERSTORMS WILL STILL BE POSSIBLE...BUT ACTIVITY WILL BE LESS WIDESPREAD THAN TYPICAL OF LATE JULY RAINY SEASON. EARLY NEXT WEEK...AN UPPER LEVEL TROUGH AND ASSOCIATED COLD FRONT WILL DIG INTO THE DEEP SOUTH AND SOUTHEAST CONUS. AFOREMENTIONED HIGH PRESSURE SHOULD KEEP THESE FEATURES FROM HAVING MUCH IMPACT ON SOUTH FLORIDA...BUT OVERALL WINDS BECOMING MORE SOUTHERLY/SOUTHWESTERLY...AS OPPOSED TO SOUTHEAST...MAY ALLOW FOR CONVECTION TO SPREAD TOWARD EAST COAST MORE. SLIGHTLY WARMER TEMPERATURES COULD ALSO RESULT. MARINE... HIGH PRESSURE BUILDING OVER THE WATERS WILL RESULT LIGHT WINDS...SOUTH AT 10 KTS OR LESS...AND SEAS OF 2 FEET OR LESS...THROUGH THE WEEKEND. THUNDERSTORMS WILL BE LESS WIDESPREAD THAN PREVIOUS FEW DAYS...BUT SCATTERED ACTIVITY IS STILL POSSIBLE THROUGHOUT THE PERIOD. && .PRELIMINARY POINT TEMPS/POPS...
