...COOLER AIRMASS ON THE WAY...

.UPDATE...

A FEW BROKEN BANDS OF PRE-FRONTAL SHOWERS AND ISOLATED TSTORMS
WERE EDGING EASTWARD ACROSS SOUTHERN GA AND IMPACTING OUR NW GA
ZONES FROM JEFF DAVIS TO ATKINSON COUNTY. PRECIP IS EXPECTED TO
CONTINUE TO DWINDLE THROUGH MIDNIGHT AS IT ENCOUNTERS DRY LOW/MID
LEVEL AIR ACROSS THE DEEP SOUTH AS REFLECTED IN THE 00Z JAX/TAE
RAOBS AND INSTABILITY LESSENS WITH THE LOSS OF DIURNAL HEATING.
WILL CONTINUE WITH THE FORECAST TRENDS OF LOW 20-30% RAIN CHANCES
WITH ISOLD THUNDERSTORMS DUE TO ELEVATED INSTABILITY THROUGH
MIDNIGHT FOR OUR SE GA ZONES MAINLY N OF WAYCROSS...THEN SHOWERS
FADING INLAND WITH DEVELOPMENT OVER THE ADJACENT COASTAL WATERS
THROUGH SUNRISE THU. A COOL NORTHERLY FLOW WILL TRAIL THE FRONTAL
PASSAGE TONIGHT WITH TEMPS IN THE MID/UPPER 50S OVER SE GA BY
DAYBREAK THU WITH LOW 60S OVER NE FL WITH PATCHY LATE NIGHT FOG
AND LOW CLOUDS MOST PROBABLE OVER THE SUWANNEE RIVER VALLEY AFTER

PASSAGE TONIGHT WITH LOSS OF DAYTIME HEATING AS THE FRONT NEARS
THE FL-GA STATE-LINE THROUGH SUNRISE. LEFT PRECIP OUT OF THE SSI

POSSIBLY VQQ. THE HRRR ADVERTISED LOW IFR CIGS DEVELOPING OVER THE
SUWANNEE RIVER VALLEY AFTER MIDNIGHT UNDER SW FLOW OUT OF THE
GOMEX JUST AHEAD OF THE SFC FRONT...THEN THE LOW CIGS DRIFTING
EASTWARD TOWARD GNV AND POSSIBLY VQQ THROUGH SUNRISE. BY EARLY
AFTN THU...THE FRONT WILL BE PUSHING SOUTHWARD OVER NE FL...AND
WITH DAYTIME HEATING AND WEAK FORCING COMBINED WITH LOW/MID LEVEL
MOISTURE CONTINUED TO ADVERTISE VCSH IN THE NE FL TAFS. NNE FLOW
DEVELOPS THU EVENING...WITH THE NAM12 BUFR SOUNDING SUGGESTING
LOWER MVFR CIGS MOVING INLAND FROM THE ATLANTIC.
