AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
722 AM EDT WED OCT 1 2014

.PREV DISCUSSION... /ISSUED 428 AM EDT WED OCT 1 2014/

SHORT TERM /TODAY THROUGH THURSDAY/...

MAINLY QUIET WEATHER IN STORE FOR NORTH AND CENTRAL GEORGIA THROUGH
THE SHORT TERM...THOUGH THAT CHANGES AS WE TRANSITION INTO THE
EXTENDED. WEAK RIDGING ALOFT WITH SURFACE HIGH PRESSURE DOMINATES
THE SOUTHEAST. A VERY STRONG TROUGH PUSHES OFF THE ROCKIES TOMORROW
INCREASING THE AMPLITUDE OF THE OVERALL WAVE...SO WEAK RIDGING TODAY
GIVES WAY TO MUCH STRONGER RIDGING OVER THE SOUTHERN APPALACHIANS
TOMORROW. THE BIG STORY THROUGH THE SHORT TERM WILL BE THE
INCREASING TEMPERATURES. WELL ABOVE NORMAL HIGHS EXPECTED TODAY...
GENERALLY MID TO UPPER 80S...AND VERY SIMILAR TOMORROW. FOR ATLANTA
THE CURRENTLY FORECAST HIGHS /85 BOTH DAYS/ ARE ONLY 4 DEGREES OFF
FROM RECORDS /RECORD IS 89 FOR BOTH DAYS/...THOUGH OTHER CLIMATE
SITES ARE QUITE A BIT FURTHER AWAY FROM RECORD VALUES. NOT MUCH IN
THE WAY OF WIND EITHER SO IT MIGHT BE KIND OF OPPRESSIVE OUT THERE
IN A RELATIVE SENSE...FOR OCTOBER 1. MIGHT GET A LITTLE MORE OF A
BREEZE ON THURSDAY IN ADVANCE OF THE APPROACHING TROUGH BUT WITH THE
SOUTHERLY FLOW KICKING UP IT WILL JUST SERVE TO INCREASE SURFACE
MOISTURE AND HUMIDITY. MAY BEGIN TO SEE A SLIGHT INCREASE IN CLOUDS
THURSDAY AS WELL. BIGGER CHANGES COMING FOR THE EXTENDED.

TDP

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...

UPPER RIDGE MOVING OFF THE ATLANTIC COAST THURSDAY NIGHT AS A COLD
FRONT ENTERS THE MS VALLEY. FRONT APPROACHING NORTHWEST GA AROUND
18Z FRIDAY AND MOVING THROUGH THE FORECAST AREA FRIDAY AFTERNOON AND
INTO FRIDAY NIGHT. INSTABILITY SUFFICIENT FOR THUNDERSTORMS DURING
THAT TIME WITH BEST CAPES AROUND 1500 AND LIFTED INDEX VALUES OF
MINUS 3 TO MINUS 5. SEVERE POTENTIAL LOOKS LIMITED FOR NOW. SHARP
TROUGH CROSSING THE SOUTHEAST SATURDAY AND SUNDAY WITH DRY AND
COLDER AIR. SOME MODIFICATION FOR THE FIRST OF THE WEEK. LOOKS LIKE
A SHORT WAVE MOVES ACROSS THE OH/TN VALLEYS ON TUESDAY AND HAVE
INCLUDED LOW POPS ACROSS THE FAR NORTH. TEMPERATURES SHOULD BE WARM
FOR FRIDAY AHEAD OF THE FRONT...BUT CLOUDS AND RAIN WILL MODIFY
THOSE VALUES. TEMPERATURES COOLING DOWN FOR THE WEEKEND.
