.PUBLIC...MODELS IN GOOD AGREEMENT WITH GFS/AVN DOING A SLIGHTLY
BETTER JOB WITH RESPECT TO DEEP LEVEL MOISTURE THROUGH 18 UTC. WILL
LEAN A BIT MORE HEAVILY TOWARD GFS MAV MOS GUIDANCE THIS PACKAGE.

FRONTAL SYSTEM OVER NORTH GA/AL SHOULD DROP DOWN TOWARD THE
FORECAST AREA (FA) OVERNIGHT WITH THUNDERSTORMS POSSIBLE AHEAD OF IT
THIS EVENING. LOOKS LIKE 20 PERCENT POPS ACROSS THE NORTHERN ZONES
FOR RIGHT NOW. SPC HAS THE EXTREME NORTHERN MOST COUNTIES UNDER A
SLIGHT RISK AND WILL HAVE TO SEE HOW WELL THE LINE/OUTFLOW BOUNDARIES
HOLD TOGETHER AS THE DROP SOUTH BEFORE I DECIDE TO INCREASE POPS UP
THERE. OTHERWISE...OVERNIGHT WILL INDICATE 10 PERCENT POPS/SLIGHT
RISK TSTMS ACROSS THE CENTRAL PORTIONS AND NEGLIGIBLE POPS EXTREME
SOUTH.

MONDAY INTO TUESDAY THE FRONT DROPS SOUTH OF THE FORECAST AREA INTO
CENTRAL FLORIDA WITH SOME DRY AIR FILTERING INTO THE AREA AND A
(WELCOME) COOL DOWN AS THE SURFACE HIGH MOVES OVER THE FA ON
TUESDAY. WILL INDICATE SOME SLIGHT CHANCE POPS OVER THE SOUTHERN
PORTIONS EARLY IN THE PERIOD AND DROP THEM MONDAY NIGHT. WILL KEEP
TEMPS SLIGHTLY ABOVE MAV GUIDANCE ON MONDAY.

.EXTENDED...THE FRONT BEGINS TO RETURN NORTH AS A WARM FRONT BUT
GETS HUNG UP OVER THE AREA THROUGH LATE WEEK. A SERIES OF UPPER
IMPULSES WILL ROTATE THROUGH THE BASE OF THE UPPER TROUGH AND ACROSS
THE FA WITH THE FRONT AS A LOW LEVEL FOCUSING MECH. WILL SEE A FEW
SURGES OF MOISTURE/TSTMS MOVE ACROSS THE AREA WITH EACH.  WILL SEE
TEMPS NEAR OR SLIGHTLY ABOVE CLIMO FOR MOST OF THE WEEK.

.MARINE...WINDS ARE CERTAINLY NOT THAT IMPRESSIVE OFFSHORE...SW
ABOUT 10 KT GUSTING TO 14 KT DUE TO LACK OF GOOD LOW LEVEL MIXING
GOING ON THERE. SEAS 2-3 FT. WINDS SHIFT FROM SW TO NW THROUGH MON
WITH THE FRONTAL PASSAGE. GFS GUIDANCE STRONGER TONIGHT IN THE SW TO
W FLOW AND BASED ON RUC AND MESO-ETA 1000 MB FLOW MAY GO WITH SCEC
HEADLINE...STRONGER WINDS LIKELY TO BE JUST OFFSHORE. WINDS SLACKEN
ON MON WITH ANOTHER SURGE IN NW FLOW MON NIGHT WITH COLD ADVECTION.

.FIRE WX...AT THIS TIME THE DISPERSION CALCULATION YIELDS INDICES
IN THE LOWER 80S (ON A CONSERVATIVE ESTIMATE) SO THE RED FLAG WARNING
