AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
157 PM EDT MON AUG 31 2015

.NEAR TERM /THROUGH TUESDAY/...
THE REMNANTS OF ERIKA ARE PUSHING NORTH/NORTHWEST ALONG THE
EASTERN GULF OF MEXICO. SCATTERED SHOWERS ARE EXPANDING ACROSS
NORTH-CENTRAL FLORIDA WITH A FEW SHOWERS MOVING INTO NE FL.
EXPECT LITTLE ADDITIONAL PUSH TO THE NORTH...WITH SE GA REMAINING
GENERALLY DRY THROUGH TNGT...WITH SCATTERED POPS FOR NE FL.
WILL USE LOW END NUMEROUS POPS FOR NORTH-CENTRAL FL LATE THIS
AFTN INTO EARLY EVENING. WITH RAINFALL RATES REMAINING ON THE
GENTLE SIDE...WILL CANCEL THE FLOOD WATCH. NAM/HRRR SHOW A
RATHER PERSISTENT BAND OF PRECIP THIS EVENING INTO THE OVERNIGHT
HOURS FOR NORTH-CENTRAL FL...WITH OTHER HIGH RESOLUTION MODELS
SHOWING LESSER COVERAGE. WILL SPLIT THE DIFFERENCE USING MAINLY
SCATTERED POPS LATE THIS EVENING INTO THE OVERNIGHT WITH A
DECREASING TREND LATE. LOWS IN THE MID 70S WILL PREVAIL.

TUESDAY...PERSISTENT RICH SOUTHERLY FLOW WILL CONTINUE AS THE
REGION RESIDES BETWEEN RIDGING ACROSS THE WESTERN ATLANTIC AND
UPPER LEVEL LOW PRESSURE ACROSS EASTERN TX. WITH PERIODIC IMPULSES
RIDING ACROSS THE AREA IN THE DEEP SOUTHERLY FLOW...EXPECT THE
ABOVE NORMAL PRECIP PATTERN TO CONTINUE. WILL USE HIGH END
SCATTERED TO NUMEROUS POPS TUESDAY AFTN FOR MOST AREAS...WITH
A BIT LESS COVERAGE FOR INTERIOR SE GA IN SLIGHTLY DRIER DEEP
LAYER MOISTURE. HIGHS IN THE UPPER 80S/AROUND 90 WILL PREVAIL.

.SHORT TERM /TUESDAY NIGHT THROUGH FRIDAY/...
MEAN UPPER LEVEL RIDGING WILL REMAIN OVER THE EASTERN HALF OF THE
CONUS THROUGH LATE WEEK WITH WEAK TROUGHING IN THE LOWER LEVELS.
THE TROPICAL MOISTURE PLUME FROM WHAT IS LEFT OF ERIKA SHOULD
CONTINUE TO ENHANCE THE CONVECTION THROUGH WEDNESDAY WITH MORE
DIURNAL AFTERNOON ACTIVITY ON THURSDAY AND FRIDAY. LOOKS LIKE MOST
OF THE THUNDERSTORM ACTIVITY LATE WEEK WILL BE SUPPRESSED TO THE
FLORIDA PENINSULA AND THE FL-GA STATE LINE AREA. OVERALL
TEMPERATURES WILL BE PRETTY CLOSE TO CLIMATOLOGY.

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
GFS INDICATES A BACK DOOR FRONT MOVES INTO THE REGION ON FRIDAY
NIGHT WITH A WEDGE-LOCAL NORTHEASTER SETTING UP...AT LEAST IN THE
NORTH PORTIONS OF THE AREA WHILE ECMWF IS NOT AS BULLISH ON IT.
RIGHT NOW LIKING THE GFS SOLUTION BETTER IF ONLY BECAUSE IT HAS
BEEN MY EXPERIENCE THE GFS DOES BETTER WITH THE WEDGES. AS WITH
MOST OF THE SEPTEMBER WEDGES/NORTHEASTERS THIS ONE SHOULD BE ABLE
TO TAKE ADVANTAGE OF WARM WATERS AND ENHANCED LIFT INLAND TO
DEVELOP SHOWERS AND THUNDERSTORMS OVER THE COASTAL AREAS FROM
SAINT SIMONS SOUTHWARD. LOOKS LIKE A COASTAL LOW DEVELOPS OVER THE
BAHAMAS AREA LATE IN THE PERIOD AND WILL HAVE TO BE MONITORED TO
SEE WHAT IT DOES WITH RAINFALL AND TIGHTENING UP THE LOCAL COASTAL
WIND GRADIENT. WITH THE NORTHEASTER LOOK FOR HIGH TEMPS TO BE IN
THE UPPER 80S COASTAL AND LOWER 90S INLAND AND RAINFALL POPS TO BE
ENHANCED ALONG THE COAST. CHOPPY SURF AND STRONG RIP CURRENTS WILL
LIKELY BE FELT FOR AREA BEACHES THIS WEEKEND.

&&

.AVIATION...
VFR WILL GENERALLY PREVAIL FOR THE NEXT 24 HOURS. RESIDUAL PATCHES
OF MVFR CIGS WILL BE POSSIBLE TIL 20Z...WITH ADDITIONAL AREAS OF
MVFR POSSIBLE AT GNV WITH SCATTERED AFTN TSTMS. WITH COVERAGE OF
THIS LIMITED...DID NOT INCLUDE AND USED VCTS.
