AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
305 PM EDT TUE APR 29 2008

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...

UPPER TROUGH AXIS MOVING THROUGH THE REGION THIS AFTERNOON AS COLD
CANADIAN HIGH SETTLES INTO THE REGION. WINDS STILL GUSTY TODAY
BUT AS THE HIGH DOMINATES TONIGHT...WINDS SHOULD SUBSIDE. GUIDANCE
TEMPS HAVE COME IN COOLER AGAIN FOR TONIGHT SO DECIDING ON A
FORECAST WAS A BIT OF A STRUGGLE. LATELY...A MAV/MET BLEND HAS
BEEN THE BEST FORECAST AND TONIGHT THE MAV IS MUCH COOLER THAN THE
MET. HAVE CONTINUED THE TREND OF GOING WITH A BLEND...FOR EXAMPLE
COULD NOT QUITE BRING MYSELF TO GO BELOW FREEZING AT LA GRANGE.
HOWEVER...WOULD NOT BE SURPRISED TO SEE A FEW AREAS DROP BELOW THE
FREEZING LINE ESPECIALLY IN SHELTERED LOCATIONS. AFTER DISCUSSION
WITH UGA EXTENSION SERVICES...DISCOVERED THAT SOME SHELTERED
VALLEYS IN THE MOUNTAINS DROPPED TO THE MID 30S LAST NIGHT...AND
WITH A COOLER NIGHT IN STORE TONIGHT...CAN EXPECT VERY ISOLATED
FREEZING POCKETS. ALSO...PER SAME DISCUSSION...DECIDED TO ISSUE
FROST ADVISORY FOR A GOOD PORTION OF THE AREA DUE TO SENSITIVE
CROPS STILL IN BLOOM. FORECAST DEWPOINTS WERE A BIT OF A CHALLENGE
BUT EVEN WITH LOWERING DEWPOINTS AND RAISING TEMPERATURES...
SEVERAL LOCATIONS SHOULD REACH SATURATION AND ANYTHING 37 DEGREES
OR BELOW WOULD EXPERIENCE FROST. PLUS WITH WINDS SUBSIDING...MANY
LOCATIONS WILL DECOUPLE OVERNIGHT...AND PRUDENT COURSE OF ACTION
IS TO ENSURE THAT FARMERS AND GARDENERS ARE PROPERLY NOTIFIED.

HIGH WILL BEGIN TO SHIFT EAST ON WEDNESDAY AS WEAK RIDGING BUILDS
IN ALOFT. SEE BELOW FOR FIRE WEATHER CONCERNS. LATE ON
WEDNESDAY...WE WILL BEGIN TO SEE MOISTURE RETURNING TO THE REGION
AS WINDS SHIFT AROUND TO THE SOUTH. STRONG SYSTEM GEARING UP IN
THE PLAINS AT THIS TIME...BUT WILL NOT AFFECT US FOR THE SHORT
TERM. SOME CONCERNS ABOUT THE GFSS HANDLING OF THIS SYSTEM FOR
THE SHORT TERM...BUT SINCE THIS DOES NOT AFFECT US JUST YET DID
NOT HAVE TO TAKE THESE INTO ACCOUNT. A VERY PLEASANT SHORT-TERM
FORECAST IN STORE WITH SLOWLY RECOVERING TEMPERATURES.

.LONG TERM /FRIDAY THROUGH TUESDAY/...

FRONT BEGINS TO PUSH INTO THE AREA FRIDAY EVENING...AND THOUGH
THERE ARE STILL SIGNIFICANT DIFFERENCES IN THE MODELS...THEY ARE
STARTING TO COME INTO AT LEAST SOME AGREEMENT. GFS IS STRONGER AND
STILL MUCH FASTER FASTER THAN THE ECMWF...AND TODAYS RUN HAS SPED
THE SYSTEM UP FROM YESTERDAY...NOW BRINGING IT THROUGH MOST OF THE
AREA SATURDAY MORNING...EXITING THE CWA BY SATURDAY EVENING. THIS
WOULD MEAN LESS CHANCE OF SEVERE EXCEPT PERHAPS IN THE SOUTHEAST
CWA...AND WILL HAVE TO KEEP AN EYE ON SUBSEQUENT FORECASTS AS THE
MODELS CONTINUE TO RESOLVE THE SYSTEM. HOWEVER...WERE AT THE TAIL
END OF THE STRONGLY OCCLUDED FRONT WITH MOST OF THE DYNAMICS WELL
NORTH TOWARD THE GREAT LAKES (GETTING TO BE THAT TIME OF
YEAR)...SO WILL HAVE TO SEE. ECMWF IS ALSO FURTHER SOUTH WITH THE
UPPER LOW...SO OVERALL STILL HAVE MINIMAL CONFIDENCE IN THE
SOLUTIONS. BY THE END OF THE EXTENDED...ABSOLUTELY NO AGREEMENT
BETWEEN THE MODELS AS THE ECMWF FINALLY PUSHES THE FRONT THROUGH
AND HAS WEAK RIDGING IN PLACE WHILE THE GFS IS DEVELOPING ANOTHER
LOW IN THE PLAINS. WAY TOO MANY DIFFERENCES TO HAVE ANY
CONFIDENCE.

&&

.FIRE WEATHER...

DRY CONDITIONS HAVE SETTLED INTO THE REGION BEHIND THE COLD FRONT
THAT MOVED THROUGH ON MONDAY...AND FUEL MOISTURES HAVE DRIED THIS
AFTERNOON TO AROUND 10% BY AFD TIME. WILL CONTINUE RFW FOR TODAY
AND BASED ON DEWPOINTS FOR WEDNESDAY AFTERNOON...WILL ISSUE RFW
FOR SOUTHWESTERN CORNER OF THE AREA. MOISTURE SHOULD CONTINUE
RETURNING TO THE AREA WEDNESDAY NIGHT INTO THURSDAY SO CRITICAL
FIRE WEATHER CONDITIONS ARE NOT ANTICIPATED AFTER WEDNESDAY.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH AND CENTRAL GEORGIA.

.DAY ONE...THIS AFTERNOON AND TONIGHT
DANGEROUS FIRE WEATHER CONDITIONS ARE EXPECTED OVER MUCH OF
CENTRAL GEORGIA THIS AFTERNOON AND EVENING.

.SYNOPSIS...
HIGH PRESSURE CENTERED OVER THE CENTRAL U.S. WILL BUILD ACROSS
THE SOUTHEAST STATES THROUGH TONIGHT.

.PRIMARY HAZARDS...
THE PRIMARY HAZARD WILL BE DANGEROUS FIRE WEATHER CONDITIONS DUE
TO LOW RELATIVE HUMIDITIES AND LOW FUEL MOISTURE LEVELS.

.DISCUSSION...
THE HIGH PRESSURE SYSTEM WILL GIVE NORTH AND CENTRAL GEORGIA A VERY
DRY AIR MASS. THIS AFTERNOON HUMIDITY VALUES WILL FALL TO 25
PERCENT OR LESS. THE DRY AIR AND LOW FUEL MOISTURE VALUES WILL
COMBINE TO PRODUCE DANGEROUS FIRE WEATHER CONDITIONS.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY
THERE WILL BE A CHANCE OF THUNDERSTORMS FRIDAY THROUGH
SATURDAY...AND THEN AGAIN MONDAY NIGHT INTO TUESDAY. NO HAZARDOUS
WEATHER IS ANTICIPATED DURING THE REST OF THE PERIOD AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT EXPECTED THROUGH TONIGHT.
