Area forecast discussion, Jul 3, 3:52 PM EDT, 13 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 352 PM EDT FRI JUL 3 2015 .DISCUSSION... THRU TONIGHT...SOME DRIER AIR HAS LIMITED COVERAGE OF STORMS SO FAR. EAST COAST SEA BREEZE IS SPARKING SOME CONVECTION WHICH IS PUSHING THE BOUNDARY INLAND FAIRLY QUICKLY. THERE SHOULD BE SOME INCREASE IN STORM COVERAGE EARLY THIS EVE DUE TO BOUNDARY COLLISION NEAR LAKE COUNTY. STEERING FLOW IS QUITE WEAK SO SLOW MOVING STORMS WILL PRODUCE LOCALLY HEAVY RAIN. THAT ALSO MEANS THERE SHOULD NOT BE AS MUCH PUSH BACK TO THE EAST COAST...THOUGH A FEW CELLS COULD MAKE A RUN FOR THE VOLUSIA/FLAGLER COAST. CONVECTION SHOULD DIMINISH BY LATE EVENING. ON SAT...SOME HIGHER MOISTURE LIFTING NORTH SHOULD PRODUCE A HIGHER COVERAGE OF STORMS INITIATING ALONG OR JUST INLAND FROM THE TREASURE COAST AROUND MIDDAY WITH THE SEA BREEZE. SAT-MON...POSITIVELY TILTED RUNNING FROM THE GREAT LAKES THROUGH THE OH VLY TO THE LWR MS VLY WILL SLIDE EWD WITH THE SRN PORTION OF THE TROUGH BREAKING OFF AND LAGGING OVER THE SERN CONUS THIS WEEKEND BEFORE STARTING TO LIFT OUT TO THE NE ON MONDAY. THIS WILL KEEP THE LOW LEVEL RIDGE AXIS OVER THE CENTRAL PENINSULA INTO EARLY NEXT WEEK WITH SWRLY STEERING LYR FLOW TENDING TO PUSH ACTIVITY BACK TOWARD THE EAST COAST DURING THE LATE AFTERNOON/EARLY EVENING. THIS TYPE OF REGIME CONTINUE TO FAVOR THE ERN SIDE OF THE PENINSULA FOR DIURNAL CONVECTION. POPS REFLECT THIS...AVERAGING 50-60 PCT WHICH IS ABOUT 10-20 PCT ABOVE EARLY JULY CLIMO. TEMPS WILL AVERAGE CLOSE TO NORMAL. TUE-THU..GLOBAL MODEL GUIDANCE SHOWS SOME DISPARITY IN HOW MUCH MID LEVEL RIDGING BUILD BACK INTO THE MID ATLC/SERN CONUS AND FL FROM MID TO LATE NEXT WEEK. THE GFS IS MORE AGGRESSIVE TOWARD THIS END WHILE THE ECM SHOWS ADDITIONAL SHORT WAVE TROUGHING MOVING INTO THE ERN CONUS AND ERODING THE WRN PORTION OF THE RIDGE. BOTH MODELS INDICATE A TUTT-TYPE LOW REACHING THE BAHAMAS ON WED AND EITHER MOVING INTO SE FL (ECM) OR ACROSS THE BREADTH OF SOUTH FL (GFS) ON THU. WOULD EXPECT TO SEE SOME SUPPRESSION OF DIURNAL CONVECTION ON THE CONVERGENT/SUBSIDENT FORWARD/W-NW FLANK OF THIS FEATURE BEGINNING SOMETIME IN THE WED NIGHT-THU NIGHT TIME FRAME. FCST GRIDS SHOW CLIMO POPS TUE TRENDING SLIGHTLY LOWER FOR WED-THU HOWEVER POPS COULD BE A LITTLE LOWER THAN ADVERTISED ON ONE OR BOTH OF THOSE DAYS DEPENDING ON THE MOVEMENT OF THE TUTT LOW. TEMPS ARE EXPECTED TO REMAIN NEAR NORMAL. && .AVIATION... INLAND MOVING SEA BREEZE WILL COLLIDE WITH WEST COAST BREEZE OVER THE INTERIOR 22Z-24Z ROUGHLY OVER LAKE COUNTY. HAVE INTRODUCED TEMPO TSRA FOR KLEE WHILE KEEPING OTHER INTRR TERMINALS IN VCTS. THERE SHOULD NOT BE MUCH PUSH BACK TO THE COAST EXCEPT POSSIBLY VOLUSIA COUNTY. ON SAT...MODELS SHOW CONVECTIVE INITIATION ONCE AGAIN ALONG THE TREASURE COAST 16Z-18Z SPREADING NORTH AND INLAND. && .MARINE... TONIGHT...E/SE FLOW 10-15 KNOTS NEAR THE COAST WILL VEER TO THE S/SW AND DECREASE LESS THAN 10 KNOTS AFTER MIDNIGHT. MOST OF THE CONVECTION SHOULD REMAIN OVER LAND THIS EVENING. SAT-TUE...BOTH THE NWPS AND WNWAVE FLAVORS OF WAVE MODEL GUIDANCE APPEAR TO BE BACK TO SUMMER-LONG BIAS OF GENERATING PEAK SEAS AVERAGING ABOUT A FT HIGHER THAN REALITY. POSITION OF RIDGE AXIS INVOF CENTRAL FLORIDA THROUGH EARLY NEXT WEEK WILL KEEP PEAK WINDS NEAR 15KT WITH SEAS AROUND 3FT WELL OFFSHORE...2FT OR A LITTLE LESS NEAR SHORE. && .PRELIMINARY POINT TEMPS/POPS...
