AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 334 PM EDT MON JUL 6 2015 .DISCUSSION... TONIGHT...CONVECTION SLOWER TO GET GOING ALONG THE EAST COAST SEA BREEZE BUT THE WEST COAST BOUNDARY WAS QUITE ACTIVE. THIS WILL SET UP A STRONG EAST/WEST BOUNDARY COLLISION. THE LATEST HRRR MODEL RUN SHOWS THIS OCCURRING TOWARDS THE EAST SIDE OF THE PENINSULA FROM ORLANDO/CAPE CANAVERAL NORTH EARLY THIS EVENING...THEN THE FOCUS SHOULD SHIFT ACROSS SOUTH BREVARD AND REACH TO OKEECHOBEE BY LATE IN THE EVENING. COVERAGE WILL PROBABLY BE 50-60 PERCENT...BUT NOT AS HIGH AS LAST NIGHT. A FEW OF THE STORMS WILL BE STRONG TO MARGINALLY SEVERE WITH FREQUENT LIGHTNING BEING THE MAIN THREAT. TUE-WED...SURFACE RIDGE AXIS OVER THE CENTRAL PENINSULA ON TUE WILL BEGIN TO LIFT SLIGHTLY NORTH ON WED. LIGHT S/SSW MORNING WINDS WILL TRANSITION TO SE/ESE EACH AFTERNOON. PRECIPITABLE WATER VALUES ARE FORECAST 1.70-1.90 INCHES ON TUE THEN DRIER AIR IS STILL FORECAST TO INFILTRATE FROM THE SOUTHEAST LATE WED. LATEST MOS HAS HIGHEST COASTAL POPS IN THE NORTH...TO THE NORTH OF THE SURFACE RIDGE AXIS. WILL GO CLOSE TO THEIR 40-50 PERCENT VALUES FOR THE NORTH COAST AND OVER THE INTERIOR. ON WED...20-30 PERCENT ARE INDICATED ALONG THE EAST COAST AND AROUND 40 PERCENT FOR THE INTERIOR. STEERING FLOW STILL LOOKS TO BE LIGHT SOUTHWESTERLY ON TUE...THEN SERLY/ERLY ON WED. THU-MON...(MODIFIED PREVIOUS DISCUSSION) THE CENTER OF MID-LEVEL HIGH PRESSURE WILL RETROGRADE WESTWARD FROM THE WESTERN ATLC TOWARDS THE DEEP SOUTH DURING THIS TIME. AT THE SURFACE...HIGH PRESSURE RIDGING OVER THE NORTH PENINSULA ON THU WILL GET NUDGED FURTHER SOUTH THIS WEEKEND BACK ACROSS THE CENTRAL PENINSULA. ERLY STEERING FLOW FOR STORMS FORECAST EACH DAY IN THE EXTENDED WITH AFTERNOON/EVENING FOCUS FOR STORMS ACROSS THE WESTERN PENINSULA. AS A RESULT EXPECT BELOW NORMAL PCPN CHANCES THROUGH MOST OF THIS PERIOD. CONSENSUS MOS POPS HAVE RISEN FOR SUN/MON AS THE MODELS INDICATE A BACK DOOR FRONTAL TROUGH APPROACHING. TEMPERATURES SHOULD BE WITHIN A COUPLE DEGREES OF CLIMO FOR BOTH HIGHS/LOWS. && .AVIATION... SEA BREEZES PUSHING SLOWLY INLAND AND THERE WILL BE A MERGER BETWEEN THE TWO AGAIN DURING THE LATE AFTERNOON AND INTO EVENING. THERE IS STILL SOME WESTERLY STEERING FLOW...SO THE STORMS THAT FORM INLAND WILL PROBABLY PUSH BACK AND TEMPO GROUPS MAY BE NEEDED INTO EVENING AT SOME OF THE EAST COASTAL SITES. CONVECTION IS EXPECTED TO DIMINISH DURING THE LATE EVENING. ON TUE...THE ATMOSPHERE IS FORECAST TO BE TYPICALLY MOIST. STEERING FLOW LOOKS WEAKER WHICH SHOULD FAVOR THE HIGHEST AFTERNOON STORM CHANCES ACROSS INLAND SITES. && .MARINE... TUE-FRI...SURFACE RIDGE AXIS OVER THE CENTRAL PENINSULA TUE WILL LIFT INTO NORTH FLORIDA WED-FRI. A FEW STORMS MAY MOVE OFF OF THE COAST FROM THE CAPE NORTHWARD TUE. STEERING FLOW THEN BACKS TO EASTERLY WED-FRI AND SOME DRYING OCCURS...BRINGING DECREASED STORM CHANCES TO THE WATERS. FAVORABLE BOATING CONDITIONS WITH SEAS AOB 3 FT.
