AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
437 AM EDT SUN MAY 5 2013

.SHORT TERM /TODAY THROUGH TONIGHT/...
SHOWERS CONTINUE TO PERSIST ACROSS MUCH OF THE AREA THIS MORNING AS
UPPER LOW CIRCULATES OVER THE SOUTHERN MISSISSIPPI VALLEY. ALREADY
SEEING SOME CLEARING ACROSS WESTERN GEORGIA...AND EXPECT THIS TREND
TO CONTINUE THROUGH THE DAY FROM WEST TO EAST...ALLOWING FOR SOME
REPRIEVE BEFORE NEXT ROUND OF SIGNIFICANT RAINFALL. AS UPPER LOW
TRANSITIONS EASTWARD THROUGH THE DAY...ADDITIONAL PERIODS OF RAIN
ARE EXPECTED...ESPECIALLY LATE THIS AFTERNOON THROUGH TONIGHT AS
AREA OF ENHANCED PRECIP MOVES INTO NORTHWEST AND WEST CENTRAL
GEORGIA. AS THE UPPER LOW MOVES OVER THE AREA...500MB TEMPERATURES
NEAR -25C AND STEEP LAPSE RATES WILL LIKELY SUPPORT THE DEVELOPMENT
OF SMALL HAIL OR GRAUPEL...ESPECIALLY THIS AFTERNOON AND EVENING. HAVE
CONTINUED TO MENTION ISOLATED THUNDER IN THE GRIDS WITH MODELS
INDICATING 200-500 J/KG...AND EXPECT THESE THUNDERSTORMS TO BE
EMBEDDED IN THE MAIN SHOWER ACTIVITY.

RAINFALL STILL EXPECTED TO EXACERBATE FLOODING ISSUES TODAY...WITH
ADDITIONAL AMOUNTS THROUGH 12Z MONDAY OF 1-3 INCHES ACROSS A BROAD
AREA OF NORTH AND EASTERN GEORGIA /GENERALLY NORTH OF I-20/. THE
HIGHEST AMOUNTS OF 2.5 INCHES OR MORE ARE EXPECTED ACROSS FAR
NORTHEAST GEORGIA...AND ISOLATED HIGHER AMOUNTS CAN BE EXPECTED.
SOILS CONTINUE TO BE SATURATED FROM THE 2 TO 4 INCHES OF RAINFALL
THAT HAVE FALLEN ACROSS THE AREA SINCE EARLY SATURDAY MORNING...AND
FLOODING IS ALREADY OCCURRING ALONG CREEKS AND RIVERS. MINOR TO
MODERATE FLOODING IS EXPECTED TO CONTINUE...ESPECIALLY ACROSS NORTH
GEORGIA. WITH THE ADDITIONAL RAINFALL EXPECTED OVERNIGHT TONIGHT AND
INTO MONDAY...HAVE OPTED TO EXTEND THE FLOOD WATCH THROUGH 7 AM
MONDAY. A SLEW OF FLOOD WARNINGS HAVE BEEN ISSUED FOR THE AREA...AND
UPDATED PRODUCTS ARE AVAILABLE ON OUR WEBSITE.

TEMPERATURES WILL REMAIN BELOW NORMAL TODAY WITH AMPLE CLOUD COVER
AND PRECIP ACTIVITY HOLDING DAYTIME HIGHS GENERALLY IN THE 60S TO
LOW 70S. HAVE INCLUDED TEMPERATURE RECORDS BELOW FOR REFERENCE.
CURRENT FORECAST HAS HIGH TEMPERATURE FOR ATHENS TODAY WITHIN A
DEGREE OF THE LOWEST MAXIMUM TEMPERATURE RECORDED. HAVE GENERALLY
GONE WITH A GUIDANCE BLEND FOR THE TEMPERATURES TODAY AND MONDAY.

.LONG TERM /MONDAY THROUGH SATURDAY/...
AN UPPER LEVEL LOW WILL MEANDER ACROSS THE STATE MONDAY AND TUESDAY.
THE MAIN CONCERN CONTINUES TO BE FLOODING...AS ANY ADDITIONAL
RAINFALL WILL JUST ADD TO ALREADY SWOLLEN OR FLOODED RIVERS AND
STREAMS ACROSS NORTH AND CENTRAL GEORGIA FROM PERSISTENT RAINS
SINCE EARLY ON SATURDAY. ALSO... COLD TEMPERATURES ALOFT ASSOCIATED
WITH THIS DEEP UPPER LOW WILL BRING A THREAT OF SMALL HAIL AND
LIGHTNING FROM ISOLATED THUNDERSTORMS ON MONDAY AND POSSIBLY MONDAY
NIGHT. THESE THREATS SHOULD SHIFT EAST OF THE STATE BY TUESDAY AS
THE UPPER LOW DRIFTS INTO THE CAROLINAS. ALTHOUGH ISOLATED SHOWERS
WILL REMAIN POSSIBLE ACROSS MAINLY NORTH GEORGIA WEDNESDAY AND
THURSDAY... THE NEXT CHANCE FOR THUNDERSTORMS WILL HOLD OFF UNTIL
FRIDAY AND SATURDAY AS A SERIES OF UPPER DISTURBANCES BEGIN TO
INTERACT WITH A MOIST AND UNSTABLE AIR MASS...COURTEOUS OF A DEEP
SOUTHERLY WIND FLOW. THE GREATER RAIN AND THUNDER CHANCES WILL BE
ON SATURDAY AS MODELS AGREE ON PUSHING A COLD FRONT INTO THE LOWER
MISSISSIPPI VALLEY BY SATURDAY AFTERNOON...THEN INTO NW GA BY LATE
SATURDAY NIGHT/EARLY SUNDAY MORNING. OTHERWISE... EXPECT COLDER
THAN NORMAL TEMPERATURES FOR MONDAY AND TUESDAY... NEARER TO NORMAL
FOR WEDNESDAY AND THURSDAY... AND ABOVE NORMAL LATE IN THE PERIOD
DUE TO THE SOUTHERLY FLOW.
