Area forecast discussion, Jul 2, 3:41 PM EDT, 39 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 341 PM EDT THU JUL 2 2015 .SHORT TERM... A DEEP LAYER RIDGE HAS REESTABLISHED ITSELF ACROSS CENTRAL FLORIDA THIS MORNING. THIS IS RESULTING IN WELL DEFINED EAST- SOUTHEAST STEERING FLOW ACROSS SOUTH FLORIDA WITH THE EAST COAST SEA BREEZE MOVING WELL INLAND EARLY THIS AFTERNOON. MOVEMENT OF STORM DEVELOPMENT WILL BE MORE TO THE NORTHWEST TODAY BUT THE HRRR SHOWS SOME WESTWARD MOVEMENT TOWARDS THE NAPLES AREA LATE THIS AFTERNOON AS THE WEST COAST SEA BREEZE RELAXES. THE SAHARAN AIR LAYER ALSO REMAINS ACROSS THE REGION AND THIS WAS REFLECTED ON THE 12Z MFL SOUNDING SHOWING VERY STEEP LOW LEVEL LAPSE RATES. HOWEVER, THE MID LEVEL LAPSE RATES HAVE WEAKENED SOMEWHAT AS 500MB TEMPERATURE WARMED SLIGHTLY SO DEVELOPMENT HAS BEEN SLUGGISH THIS AFTERNOON. BUT COULD STILL GET SOME STRONG TO ISOLATED SEVERE WIND GUSTS AND HAIL UP TO THE SIZE OF QUARTERS IN THE STRONGER STORMS WHICH WOULD TEND TO FAVOR THE AREAS SOUTH AND WEST OF THE LAKE. FRIDAY AND SATURDAY COULD BE A LITTLE MORE ACTIVE AGAIN ACROSS THE INTERIOR AS BOTH THE GFS AND ECMWF ARE SHOWING A WEAK 700MB TROUGH OVER THE EASTERN GULF OF MEXICO ALONG WITH A MOISTURE SURGE INCREASING THE PWAT IN THE RANGE OF 1.7-1.9". A GENERAL SOUTHEAST STEERING FLOW CONTINUES HOWEVER WITH THE SURFACE AND MID LEVEL RIDGE AXIS CONTINUING ACROSS CENTRAL FLORIDA. SO AGAIN FOR FRIDAY AND THE FOURTH OF JULY, THE AREA OF SHOWERS AND STORMS WOULD BE OVER THE EAST COAST LATE NIGHT/EARLY MORNING THEN SHIFTING TO THE INTERIOR DURING THE AFTERNOON AND EARLY EVENING. .LONG TERM... FOR THE EXTENDED PERIOD, A TYPICAL JULY PATTERN WILL PERSIST WITH DEEP EAST TO SOUTHEAST FLOW AS THE RIDGE AXIS REMAINS ACROSS CENTRAL FLORIDA. FORECAST SOUNDINGS ARE SHOWING PWAT FOR LATE THIS HOLIDAY WEEKEND INTO NEXT WEEK IN THE RANGE OF 1.5-1.7" WHICH IS SLIGHTLY UNDER AVERAGE SO THE EAST COAST WILL REMAIN MOSTLY DRY WITH NEAR CLIMO COVERAGE FOR THE INTERIOR AREAS. THE NAVAL RESEARCH LAB MODEL IS SHOWING ANOTHER THICK SAL TO AFFECT SOUTH FLORIDA BY THE MIDDLE OF NEXT WEEK AND THIS COULD LIMIT THUNDERSTORM COVERAGE AT THAT TIME BUT ALSO AID IN STRONGER DEVELOPMENT. && .MARINE... EAST TO SOUTHEAST WIND GENERALLY 10 KNOTS OR LESS THROUGH THE WEEKEND AND NEXT WEEK WITH SEAS LESS THAN 4 FEET BOTH OVER THE GULF AND ATLANTIC WATERS. && .PRELIMINARY POINT TEMPS/POPS...
