AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
218 PM EST FRI FEB 10 2012

.SHORT TERM /TONIGHT THROUGH SUNDAY/...
STRONG SHORTWAVE ACROSS THE CENTER OF THE COUNTRY WILL CONTINUE TO
SLIDE EAST TONIGHT...BRINGING WITH IT A QUICK SHOT OF MOISTURE.
HOWEVER...BEST MOISTURE WILL SPLIT EITHER TO THE NORTH ASSOCIATED
WITH WEAK POLAR JET OR TO THE SOUTH ASSOCIATED WITH SUBTROPICAL
JET...WITH A GOOD PORTION OF THE AREA BEING LEFT MOSTLY CLOUDY
WITHOUT ANY REAL PRECIPITATION EXCEPT FOR MAYBE A FEW SPRINKLES...
NOT REALLY ENOUGH TO ADD TO THE WX GRIDS. FOR THE SOUTHERN
PORTION OF THE AREA...EXPECT MAINLY LIGHT SHOWERS NOT REALLY
ADDING UP TO MUCH RAINFALL. FOR THE NORTH...MOISTURE ASSOCIATED
WITH THE SHORTWAVE ITSELF PLUS INCREASING OROGRAPHIC LIFT AS
NORTHWEST FLOW PICKS UP WILL LEAD TO LIGHT SHOWERS THIS AFTERNOON
BRIEFLY MIXING WITH AND QUICKLY CHANGING OVER TO SNOW SHOWERS THIS
EVENING AND OVERNIGHT. SHORTWAVE EXITS THE AREA FAIRLY QUICKLY SO
WHILE SOME OF THE SNOW SHOWERS THEMSELVES MAY BRIEFLY BE
MODERATE...DO NOT EXPECT ANY ACCUMULATIONS OTHER THAN PERHAPS A
LIGHT DUSTING. LOW TEMPS TONIGHT IN THE MOUNTAINS SHOULD GENERALLY
BE JUST BELOW FREEZING...THE REALLY COLD AIR DOES NOT MOVE IN
UNTIL SATURDAY NIGHT.

ARCTIC AIRMASS BEGINS PUSHING IN BEHIND THE SHORTWAVE SATURDAY
MORNING. THE PRESSURE GRADIENT AT THE SURFACE INCREASES
SIGNIFICANTLY DURING THE DAY...THUS WILL ISSUE A WIND ADVISORY
STARTING AT 15Z SATURDAY GOING THROUGH 00Z SUNDAY. EXPECT WINDS
BETWEEN 15-20MPH GUSTING UP TO 35MPH DURING THE AFTERNOON HOURS.

COLD AND DRY AIRMASS REALLY PUSHES INTO PLACE SATURDAY EVENING AND
OVERNIGHT. LOWS WILL DROP INTO THE TEENS NORTH AND LOWER 20S
SOUTH...LOWER THAN THEY HAVE BEEN OVER THE PAST 21 DAYS
/GENERALLY MID TO UPPER 20S/. THIS MAY BE A CONCERN FOR PLANTS
THAT ARE FRESHLY-BUDDED DUE TO THE UNSEASONABLY WARM TEMPERATURES
THE PAST COUPLE OF WEEKS. THOUGH WINDS WILL BEGIN SUBSIDING
OVERNIGHT...THERE IS A CONCERN FOR POTENTIAL WIND CHILL ADVISORY
IN THE MOUNTAINS.

FOR MOST OF THE SHORT TERM...MAV AND MET ARE IN GENERAL AGREEMENT
SO TOOK A BLEND FOR TEMPS AND POPS. HOWEVER...FOR SUNDAY...MAV
BRINGS IN VERY DRY AIR WITH DEWPOINTS BELOW 0 DEGREES F...WHEREAS
MET KEEPS DEWPOINTS IN THE 5-10 DEGREE RANGE. GFS SEEMS TO BE A
LITTLE FASTER THAN THE NAM/ECMWF WITH THE SYSTEM EXITING SO HAVE
LEANED TOWARD THE WARMER/MORE MOIST MET VALUES.

TDP

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
NO SIGNIFICANT CHANGES IN THE MEDIUM RANGE MODEL TRENDS THROUGH THE
FIRST HALF OF THE EXTENDED FORECAST PERIOD. STILL SOME CONFIDENCE
ISSUES IN THE LATTER HALF OF THE EXTENDED FORECAST WITH INCREASING
DIVERGENCE BETWEEN THE GFS AND ECMWF MODEL SOLUTIONS. NO SIGNIFICANT
CHANGES PLANNED TO THE EXTENDED FORECAST GRIDS AT THIS TIME. SEE
PREVIOUS EXTENDED FORECAST DISCUSSION BELOW FOR DETAILS.

20

PREV DISCUSSION... /ISSUED 635 AM EST FRI FEB 10 2012/
ARCTIC HIGH WILL QUICKLY MODIFY SUN AND SHIFT EAST OF THE AREA BY
EARLY MON. PROGRESSIVE ZONAL FLOW RETURNS TO ALL EXCEPT THE NE U.S.
AT THE BEGINNING OF THE EXTENDED PERIOD. A SERIES OF SOUTHERN STREAM
SHORT WAVES WILL AFFECT THE REGION DURING THE EXTENDED...WITH A
VARIETY OF ASSOCIATED WEATHER SCENARIOS. THE FIRST SUCH SYSTEM WILL
TRAVERSE THE REGION TUE. ALTHOUGH NOT AN IDEAL OR CLASSIC WEDGE SET
UP IS IN PLACE...THE RETREATING ARCTIC HIGH LEAVES ENOUGH RESIDUAL
COLD AIR IN PLACE AT THE ONSET OF THIS EVENT EARLY TUE TO AROUSE
SOME CONCERN FOR WINTER WX...MAINLY ACROSS THE NE GA MOUNTAINS.
LOW-LEVEL THICKNESS/TEMP PROFILES SUGGEST A GOOD CHANCE OF SNOW
THROUGH THE FIRST HALF OF THE DAY TUE. GFS MODEL SOUNDINGS HAVE THE
ENTIRE ATMOSPHERIC COLUMN BELOW 750MB BELOW 0C AND SATURATED AT 12Z
TUE. THE COLUMN GRADUALLY WARMS FROM THE TOP DOWN BY
00Z...SUGGESTING A CHANGE OVER TO SLEET AND RAIN. FURTHER
SOUTH...SOME WINTER PCPN POSSIBLE EARLY TUE...BUT THE THREAT APPEARS
VERY LIMITED OUTSIDE THE NE GA MOUNTAINS. THIS WILL BE A FAST
MOVING...MINIMAL QPF EVENT AT ANY RATE WITH ANTECEDENT LOW
DEWPOINTS/PWS IN PLACE. A STRONGER...DEEPER...SLOWER MOVING UPPER
TROUGH IS PROGGED TO AFFECT THE REGION DURING THE LATER HALF OF THE
WEEK. THE GFS/ECMWF DIFFER CONSIDERABLY ON EXACTLY WHEN THIS SYSTEM
WILL IMPACT THE SOUTHEAST U.S. THE GFS KICKS OUT A LEADING SHORT
WAVE LATE THU...LEAVING THE PARENT TROUGH BACK IN TX...FINALLY
MOVING THIS THROUGH THE AREA BY SAT. AS A RESULT...THIS WOULD
SUGGEST MULTIPLE ROUNDS OF PRECIPITATION. ON THE OTHER HAND...THE
ECMWF HOLDS A SHORT WAVE RIDGE ACROSS THE REGION THU-FRI...THEN
SHIFTS THE ENTIRE SYSTEM INTO THE REGION SAT-SUN. BOTH SUGGEST THAT
SAT WILL BE WET...BUT DIFFER CONSIDERABLY ON THE THU-FRI PERIOD.
OVERALL...THE SYNOPTIC PATTERN SUGGESTED BY THE ECMWF APPEARS LESS
PLAUSIBLE THAN THE GFS AT THIS POINT. THUS...WILL ADVERTISE CHC
POPS THU-SAT...WITH THE HIGHEST POPS FOR SAT. TEMPS/DEWPOINTS
SUGGEST THAT THUNDER WILL BE A THREAT WITH THIS SECOND SYSTEM. AT
THIS POINT...ANY SEVERE THREAT APPEARS LOW...BUT NOT ENTIRELY OUT OF
THE QUESTION...ESPECIALLY THU WHEN DECENT SHEAR AND MARGINAL
INSTABILITY/CAPE COMBINE. A BIGGER THREAT WILL BE HEAVY
RAIN...ESPECIALLY ACROSS CENTRAL GA...WHERE SEVERAL DAYS OF REPEATED
SHRA/TSRA MAY OCCUR...ESPECIALLY WITH THE GFS SCENARIO.
HOWEVER...THE EXCESSIVE RAINFALL AMOUNTS OF 5-7 INCHES DEPICTED
ACROSS CENTRAL AL INTO CENTRAL GA DURING THIS TIME FRAME APPEAR WAY
OVERDONE.

TEMPS WILL RETURN TO THE FAMILIAR UNSEASONABLY WARM LEVELS DURING
THE EXTENDED...WITH HIGHS IN THE 60S AND LOWS IN THE 40S AND 50S.
THE EXCEPTION WILL BE TUE...WHEN EVAPORATIVE COOLING...PCPN...CLOUD
COVER...AND LOW-LEVEL EASTERLY FLOW WILL HOLD TEMPS IN THE 40S NORTH
AND 50S SOUTH...WITH POSSIBLY ONLY 30S IN THE MOUNTAINS...ESPECIALLY
IF SNOW/SLEET MATERIALIZE IN THAT AREA AS NOTED ABOVE.

19

&&

.FIRE WEATHER...
DRY AIR WILL MOVE INTO THE REGION BEHIND THE SYSTEM...WITH
SATURDAY AND ESPECIALLY SUNDAY DRYING SIGNIFICANTLY. AT THIS TIME
HOWEVER...FUEL MOISTURES DO NOT MEET CRITERIA SO CANNOT ISSUE ANY
FIRE PRODUCTS FOR SATURDAY DESPITE STRONG WINDS AND LOWER RH
VALUES SATURDAY AFTERNOON. FUELS WILL HAVE TO BE MONITORED
THROUGH THE EVENING AND TOMORROW FOR POSSIBLE ISSUANCE. SUNDAY
DEWPOINTS FORECAST TO BE IN THE SINGLE DIGITS AND POSSIBLY BELOW 0
DEGREES F. THIS COMBINED WITH ADDITIONAL DRYING FROM STRONG WINDS
TOMORROW MAY LEAD TO FIRE DANGER CONDITIONS ON SUNDAY.

&&

AVIATION...
18Z UPDATE...
EXPECT VFR CONDITIONS THROUGH THE PERIOD EXCEPT SOME BRIEF MVFR
HAZE THROUGH THIS AFTERNOON AT AHN. BKN-OVC MIDLEVEL CLOUDS WILL
PREVAIL THROUGH MID MORNING SATURDAY. UPPER DISTURBANCE MOVING
THROUGH TONIGHT MAY BRING SOME SPRINKLES TO THE AREA...BUT NOT
ENOUGH TO INCLUDE WX IMPACTS AT ANY OF THE TAFS. SOUTHWEST WINDS
EARLY SHIFTING TO WEST AND NORTHWEST BY SATURDAY AFTERNOON. WINDS
WILL PICK UP TO BETWEEN 15-20KT GUSTING TO BETWEEN 25-30KT...
POSSIBLY BRIEFLY HIGHER.

//ATL CONFIDENCE...18Z UPDATE...
HIGH ON ALL ELEMENTS.
