AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
403 AM EDT WED APR 23 2014


.SHORT TERM /TODAY THROUGH THURSDAY/...
WEAK FRONTAL BOUNDARY CURRENTLY MOVING ACROSS CENTRAL GA THIS
MORNING. THE ACTUAL LOCATION OF THE BOUNDARY IS A LITTLE HARD TO
DISCERN IN THE WIND PATTERN AND THE PRESSURE PATTERN...AND CAN BE
SEEN THE BEST IN THE DEWPOINT FIELD. DEWPOINTS AHEAD OF THE BOUNDARY
ARE IN THE 60S...WHILE ON THE NORTH SIDE OF THE BOUNDARY DEWPOINTS
ARE IN THE 50S. PATCHY DENSE FOG HAS DEVELOPED ALONG AND SOUTH OF
THE FRONTAL ZONE. WILL HOLD OFF ISSUING A DENSE FOG ADVISORY THIS
MORNING...AS VSBYS ARE IMPROVING ONCE THE BOUNDARY PASSES. IN
ADDITION...THE DENSE FOG IS NOT WIDESPREAD WHERE IT HAS DEVELOPED.

HIGH PRESSURE WILL BEGIN TO BUILD SOUTHWARD INTO GEORGIA
TODAY...HELPING TO PUSH THE LINGERING BOUNDARY OUT OF THE CWFA. THE
OLD FRONT SHOULD SETTLE SOMEWHERE NEAR THE GA/FL LINE LATER TODAY.
THE HIGH PRESSURE RIDGE WILL START TO SHIFT OFFSHORE OVERNIGHT AND
EARLY THURSDAY. THE MODELS ARE PROGGING THE OLD FRONTAL ZONE TO
BEGIN PUSHING BACK NORTHWARD AS A WARM FRONT BY LATE THURSDAY.

THE SHORT TERM PORTION OF THE FORECAST WILL REMAIN DRY...WITH MOSTLY
SUNNY/MOSTLY CLEAR SKIES. TEMPS WILL BE RIGHT AROUND NORMAL
TODAY...THEN SLIGHTLY ABOVE NORMAL FOR THURSDAY.

NLISTEMAA


.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
HIGH PRESSURE THAT DOMINATES THE SHORT TERM MOVES EAST OFF THE
MID ATLANTIC COAST AND BECOMES CENTERED JUST OFF THE CAROLINA/GEORGIA
COAST BY 00Z FRI. THE NEXT FRONTAL SYSTEM TO AFFECT THE AREA
BEGINS DEVELOPING OVER THE PLAINS STATES WED AFTERNOON. THE MAIN
LOW CENTER DEEPENS AND MOVES NE TO THE WESTERN GREAT LAKE STATES
THU AFTERNOON. THE TAIL END OF THE ASSOCIATED COLD FRONT PUSHES INTO
NW GA BY 06Z TO 12Z FRI. THE MODELS ARE STILL SHOWING A DECENT
AMOUNT OF INSTABILITY WITH THE FRI SYSTEM SO STILL KEEPING SHOWERS
AND THUNDERSTORMS IN THE FORECAST. THE MODELS ARE ALSO STILL NOT
SHOWING MUCH AVAILABLE MOISTURE SO WE SHOULD NOT SEE ANY ISSUES
WITH FLOODING. THERE IS ANOTHER WEAKER FRONTAL BOUNDARY THAT MOVES
IN SAT MORNING WHICH HELPS TO REINFORCE THE FIRST ONE AND KEEP A
CHANCE OF PRECIP THROUGH THE BEGINNING OF NEXT WEEK. THIS PATTERN
IS LOOKING MORE AND MORE LIKE A LIKE A SUMMERTIME PATTERN THAN A
SPRING PATTERN WITH DECENT CAPE AND LOW SHEAR. STARTING
FRIDAY...CAPES AND LIS PEAK EVERYDAY AROUND 18Z AND FALL OFF
RAPIDLY BY 00Z. TEMPS ALSO LOOK MORE LIKE SUMMER BEGINNING THU
WITH HIGHS MAINLY IN THE 80S. LOWS WILL BE IN THE 50S AND 60S.

.AVIATION...

ACROSS CENTRAL GA. NO VSBY RESTRICTIONS ANTICIPATED AT ATL AT THIS
TIME...BUT IF THE FRONT IS SLOWER THAN ANTICIPATED PATCHY FOG MAY FORM.
WINDS WILL SHIFT AROUND TO THE NW BEFORE 12Z.
