AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
315 PM EDT FRI JUN 5 2015

.DISCUSSION...

CURRENTLY/TONIGHT...CONVECTION HAS BEEN MORE ACTIVE ALONG THE WEST
COAST BREEZE NORTH OF TAMPA WITH OTHER SCATTERED SHOWERS/STORMS ON
THE EAST COAST BREEZE FROM NRN BREVARD COUNTY NORTHWARD AT MID
AFTERNOON. EXPECT ADDITIONAL SHOWERS AND STORMS ACROSS THE NRN
INTERIOR INTO LATE AFTERNOON AND POSSIBLY PROPAGATING SOUTH INTO THE
SOUTHERN INTERIOR THIS EVENING ALONG SEA BREEZE AND OUTFLOW
BOUNDARIES. WILL KEEP HIGHEST POPS FOR THE NRN INTERIOR THIS EVENING
WITH DRY CONDITIONS EXPECTED ALONG THE IMMEDIATE COAST SOUTH OF THE
CAPE. AFTER EVENING CONVECTION DIMINISHES OVER THE INTERIOR SKIES
WILL BECOME PARTLY CLOUDY WITH LOWS IN THE UPPER 60S TO LOWER 70S.

SATURDAY...LOW LVL NORTHERLY FLOW BEHIND A FRONTAL TROUGH OFFSHORE
WILL VEER TO THE EAST IN THE AFTERNOON WITH THE AFTERNOON SEA
BREEZE. MID LYR FLOW FROM THE NW AT 5-10 KNOTS WILL FAVOR CONVECTION
DEVELOPING ACROSS E CENTRAL FL AS THE EAST COAST BREEZE PUSHES
SLOWLY INLAND. PRECIPITABLE WATER VALUES TICK UP A FEW TENTHS TO
NEAR 1.6 INCHES WITH MID LVL TEMPS SIMILAR TO FRIDAY. WILL KEEP
SHOWER THUNDERSTORM CHANCES IN THE SCATTERED RANGE. HIGHS MID-UPR
80S COAST TO 90-92 OVER THE INTERIOR.

SUNDAY...A BIT STRONGER ONSHORE FLOW LVL EASTERLY FLOW IS FORECAST
SUNDAY WITH HIGH PRESSURE NOSING DOWN FROM THE MID ATLC COAST. THIS
SHOULD ALLOW THE EAST COAST SEA BREEZE TO PROGRESS STEADILY THROUGH
THE INTERIOR IN THE MID TO LATE AFTERNOON. PRECIPITABLE WATER VALUES
LOOK TO DECREASE AT LEAST A FEW TENTHS OF AN INCH WITH SLIGHT RAIN
CHANCES NEAR THE COAST AND 30-40 PCT ACROSS THE INTERIOR. HIGHS MID
80S COAST TO AROUND 90 INTERIOR.

FOR MONDAY LOWERED POPS SOME WITH LIMITED MOISTURE CONTINUING AND
ESE LOW LVL FLOW. OTHERWISE...RAIN CHANCES STILL LOOK TO INCREASE
INTO MID WEEK AS LOW LVL FLOW VEERS TO SOUTHERLY AND MOISTURE
INCREASES INTO WED.

PREVIOUS EXTENDED DISCUSSION FOLLOWS...MON-THU...500MB TROUGH
FINALLY FILLS AND EJECTS SEAWARD BY TUE TO RESULT IN FLATTENED
PATTERN WED BEFORE NEXT WAVE DIGS SE TOWARD N CENTRAL GULF BY THU.
EXTENT OF E PROGRESSION SOMEWHAT IN DOUBT AND MAY ONLY TEND TO
TEMPORARILY AMPLIFY UPPER RIDGING OVER FL ATLANTIC LATER IN WEEK.
ECMWF NOT AS BULLISH...BUT BY EARLY FRI BOTH ECMWF AND GFS
EVENTUALLY PLACE ANOTHER MID/UPPER LOW OVER MID-ATLANTIC COAST.
MEANWHILE...FL SFC PATTERN WILL FIND SUBTROPICAL RIDGE AXIS EASIER
TO DISCERN AS IT NOSES W ACROSS THE PNSLA DURING THE PERIOD. LOCAL
ONSHORE FLOW WILL INCREASINGLY ACQUIRE SOUTHERLY COMPONENT AS AXIS
EMERGES AND SHIFTS. THIS WILL PROMOTE BETTER OPPORTUNITY FOR WIDER
STORM COVERAGE ACROSS FORECAST AREA...ESPECIALLY BY MID-WEEK. MAX
TEMPS UPPER 80S TO LOWER 90S WHILE MIN TEMPS GENERALLY IN LOWER 70S.

&&

.AVIATION...SCT SHRA/TSRA WILL AFFECT INTERIOR TERMINALS THRU 23Z-
01Z WITH CONVECTION REMAINING INLAND FROM CSTL TERMINALS FROM KDAB-
KTIX. VFR CONDS EXPECTED PAST 03Z AS EVENING CONVECTION DIMINISHES.
CHC SHRA/TSRA ON SATURDAY SHOULD HOLD OFF UNTIL AFT 17Z.

&&

.MARINE...LIGHT WINDS EARLY SATURDAY WILL BECOME NE-E TO 10 KNOTS IN
THE AFTERNOON WITH SEAS 2 FT NEAR SHORE AND UP TO 2-3 FT OFFSHORE.
SUN-MON...SEAS AROUND 2-3 FEET THRU THE PERIOD WITH WINDS 10 KNOTS
OR LESS HAVING A GENERAL ONSHORE COMPONENT...ESPECIALLY NEAR THE
COAST IN THE AFTERNOON. FAVORABLE BOATING CONDITIONS AWAY FROM ISOLD-
SCT STORMS. WINDS BECOMING MORE SOUTHERLY BY EARLY NEXT WEEK.
