AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
419 PM EDT THU AUG 13 2015

.NEAR TERM /REST OF THE AFTERNOON/...

A FEW STRONG TO SEVERE STORMS CONTINUE TO DEVELOP IN NE FL IN
UNSTABLE AIRMASS ALONG AND AHEAD OF COLD FRONT. DCAPE VALUES ARE
ELEVATED IN THE 1000-1400 J/KG RANGE...QUITE CONDUCIVE FOR SEVERE
DOWNBURSTS IN THIS ENVIRONMENT. TYPICALLY DURING THE SUMMER THESE
VALUES ARE UNDER 800-900...BUT GIVEN THE DRY AIR ALOFT PER WATER
VAPOR IMAGERY OUR THREAT OF DOWN BURSTS ARE MORE SO THAN PRIOR
DAYS. ALL ACTIVITY WILL CONTINUE TO DRIFT SWD THROUGH THIS
EVENING.

.SHORT TERM /TONIGHT THROUGH SUNDAY/...

A WEAK COLD FRONT WILL MEANDER AROUND NORTH CENTRAL FLORIDA THROUGH
FRIDAY. SHOWERS AND STORMS WILL DIMINISH THIS EVENING WITH LOSS OF
DAYTIME HEATING. HOWEVER...A FEW SHOWERS/STORMS COULD LINGER INTO
THE OVERNIGHT HOURS ACROSS THE SOUTHERN HALF OF MARION COUNTY.
PATCHY FOG IS POSSIBLE FOR THE NORTHWESTERN GEORGIA ZONES...TO THE
NORTH OF HIGHWAY 84 LATE TONIGHT AS SKIES CLEAR AND WINDS BECOME
LIGHT. THE OTHER TYPICAL LOCATIONS COULD SEE SOME PATCHY FOG AS
WELL. LOWS TONIGHT WILL MAINLY BE IN THE 70S.

SURFACE HIGH PRESSURE WEDGES DOWN THE LEE SIDE OF THE APPALACHIANS
AND AN INVERTED TROUGH DEVELOPS OFFSHORE ON FRIDAY. HIGHEST POPS
WILL BE ACROSS THE FAR SOUTH NEAR THE FRONT WITH LOWEST POPS ACROSS
ACROSS SE GA TOWARDS THE ALTAMAHA DUE TO DRIER AND MORE STABLE AIR.
NORTHEASTERLY FLOW WILL ALLOW THE SEA BREEZE TO PUSH INLAND...AND
ISOLATED/SCATTERED SHOWERS AND STORMS WILL DEVELOP ACROSS THE
INTERIOR AREAS DURING THE LATE AFTERNOON HOURS. TEMPERATURES WILL
BE IN THE MID/UPPER 80S TO LOWER 90S...COOLEST TOWARDS THE EAST
COAST.

RAIN CHANCES WILL INCREASE OVER THE WEEKEND AS THE SURFACE TROUGH
TO OUR SOUTH LIFTS BACK TO THE NORTH AND STALLS OVER NORTHERN
FLORIDA. AT THE SAME TIME...MID LEVEL RIDGING WILL BUILD IN FROM
OUR EAST. LIGHT LOW LEVEL ONSHORE FLOW WILL PREVAIL WHICH WILL
FIRST FOCUS CONVECTION NEAR THE COAST IN THE MORNING/EARLY
AFTERNOON. THE FOCUS FOR CONVECTION WILL THEN GRADUALLY SHIFT
FARTHER INLAND DURING THE DAY. CONVECTIVE ACTIVITY WILL BECOME
NUMEROUS EACH AFTERNOON BETWEEN THE I-95 AND I-75 CORRIDORS...WITH
THE BULK OF THE ACTIVITY ACROSS NE FL ON SATURDAY AND THEN ALSO
INTO SE GA ON SUNDAY AS MOISTURE IN THE MID AND UPPER LEVELS
INCREASES AND THE SURFACE TROUGH INCHES A LITTLE FARTHER NORTH.
ONSHORE FLOW AND POTENTIAL FOR MORNING SHOWERS WILL KEEP COASTAL
AREAS IN THE MID 80S FOR HIGHS WITH NEAR NORMAL MAX TEMPS EXPECTED
FARTHER INLAND.

.LONG TERM /MONDAY THROUGH THURSDAY/...

SCATTERED TO NUMEROUS SHOWERS AND STORMS WILL CONTINUE THROUGH THE
MIDDLE OF NEXT WEEK. THE RIDGE WILL SHIFT WESTWARD...ALLOWING MID
LEVEL TROUGHING TO MOVE INTO THE REGION. DEEP ATMOSPHERIC MOISTURE
LEVELS WILL INCREASE EVEN FURTHER. LOW LEVEL FLOW WILL BECOME MORE
SOUTHERLY AS A SURFACE TROUGH STALLS JUST NORTH OF THE REGION.
TEMPS WILL AVERAGE NEAR TO SLIGHTLY BELOW NORMAL DUE TO AN INCREASE
IN CLOUDS AND PRECIP.

&&

.AVIATION...
SCATTERED SHOWERS AND STORMS WILL CONTINUE TO PROGRESS SWD OVER
MAINLY INLAND NE FL. HIGHEST CHANCE OF ADDITIONAL STORMS WILL BE
AT GNV TERMINAL OVER THE NEXT 1-3 HOURS. TONIGHT...PREVAILING VFR
EXPECTED WITH SOME SHALLOW FOG POSSIBLE. VFR EXPECTED FRI WITH E
TO NE WINDS 10-15 KT AND GUSTY. ISOLD TO SCT SHOWERS AND STORMS
EXPECTED FRI MAINLY FROM NOON THROUGH THE AFTN.

&&

.MARINE...A WEAK COLD FRONT WILL BEGIN TO WASH OUT AS IT STALLS
ACROSS NORTH CENTRAL FLORIDA. EAST NORTHEAST WINDS 10-15 KNOTS
WILL CONTINUE THROUGH FRIDAY. AN INVERTED TROUGH WILL DEVELOP OFF
THE CENTRAL FLORIDA EAST COAST AND THEN MOVE ACROSS THE FLORIDA
PENINSULA THIS WEEKEND. ISOLATED TO SCATTERED SHOWERS AND STORMS
ARE POSSIBLE EACH DAY THROUGH THE WEEKEND.

RIP CURRENTS: LOW RISK THROUGH FRIDAY.
