Severe Thunderstorm Warning 1, NWS Atlanta, GA

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
530 AM EST MON JAN 2 2006

.SHORT TERM...(TODAY THROUGH WEDNESDAY)
CURRENT RADAR LOOP SHOWS SHOWERS AND THUNDERSTORMS MOVING NE INTO
CENTRAL GEORGIA THIS MORNING. LOOKS LIKE THIS IS THE BEGINNING OF
WHAT CAN BE AN INTERESTING WEATHER DAY. AN INTENSE UPPER LEVEL STORM
SYSTEM IS MOVING EAST FROM THE CENTRAL U.S.  AHEAD OF THIS SYSTEM
THERE HAS BEEN SOME GOOD WARM AIR ADVECTION ACROSS THE AREA WITH
TEMPS THIS MORNING STILL IN THE 50S AND 60S AND HIGHS ARE EXPECTED
IN THE 60S TO LOWER 70S. CURRENTLY SPC HAS ALMOST THE ENTIRE STATE
OUTLOOKED UNDER A MODERATE RISK OF SEVERE WEATHER FOR TODAY. THE
ATMOSPHERE ACROSS NORTH AND CENTRAL GEORGIA WILL BECOME UNSTABLE BY
MIDDAY WITH CAPES IN THE 1500 TO 2500 RANGE AND LIS BELOW MINUS 6
MOVING INTO WEST AND NORTHWEST GEORGIA BY 18Z. 850-500MB LAPSE RATES
AS STEEP AS 6.5 TO 7 DEGREES CELSIUS EXPECTED ACROSS THE REGION AT
THIS SAME TIME INDICATES A PRETTY GOOD RISK FOR LARGE HAIL. PERIODS
OF HEAVY RAINFALL WILL ALSO BE POSSIBLE WITH PW AROUND 1.5 TO 1.7
INCHES ACROSS CENTRAL GA. THIS THUNDERSTORM ACTIVITY SHOULD BEGIN
ENDING FROM THE WEST THIS AFTERNOON/EVENING BY 00Z. FOR
TUESDAY...DRY NORTHWEST UPPER FLOW DOMINATES THE REGION AS THE UPPER
TROUGH MOVES OFF THE EAST COAST AND A DECENT RIDGE BUILDS INTO THE
MISSISSIPPI VALLEY.

.LONG TERM...(WEDNESDAY NIGHT THROUGH SUNDAY)
UPPER RIDGE AXIS MOVES EAST OF THE FORECAST AREA LATE TUESDAY AS
A SURFACE HIGH PRESSURE RIDGE BUILDS IN WED. THIS RIDGE IS VERY
WEAK AND GETS PUSHED SOUTH AS ANOTHER SYSTEM MOVES INTO THE REGION
WED AFTERNOON/EVENING. THIS NEXT FRONTAL SYSTEM IS VERY DRY AND
LOOKS LIKE WE SHOULD ONLY SEE INCREASED CLOUDS OVER GEORGIA
THROUGH THURSDAY AFTERNOON. AFTER THAT THE SURFACE TO UPPER LEVEL
FLOW BECOMES NORTHWESTERLY WITH A THIRD WEAK WAVE PUSHING SOUTH
INTO THE N GA FRI MORNING. THIS WAVE SHOULD ONLY BRING SCT
PRECIPITATION AS IT REALLY DRIES UP IN THE NW FLOW. THIS NW FLOW
WILL ALSO BRING SOME COOLER TEMPS WITH MORE SEASONAL NORMS
EXPECTED THROUGH THE WEEKEND.

&&

.AVIATION...
SHOWERS AND THUNDERSTORMS WITH LARGE HAIL EXPECTED ACROSS THE STATE
THROUGH 00Z. CURRENTLY SHRA/TSRA ARE MOVING EAST INTO THE AREA AHEAD
OF DEVELOPING FRONTAL SYSTEM OVER THE LOWER MISSISSIPPI RIVER
VALLEY. BIGGEST CONCERN TODAY WILL BE THE TSRA DEVELOPMENT AND ALL
THE PERKS THAT COME WITH THEM (STRONG GUSTY WINDS...LARGE HAIL
...LIGHTNING...AND PERIODS OF HEAVY RAIN).  WINDS GENERALLY OUT OF
THE EAST TO SE AROUND 10KT TURNING W BY 00Z ONCE THIS SYSTEM MOVES
THROUGH. AS FOR THE PRECIPITATION WILL SEE MAINLY SHOWERS WITH BRIEF
PERIODS OF HEAVY RAIN IN AND AROUND THUNDERSTORMS. LARGE HAIL IS
ALSO EXPECTED WITH AND CONVECTIVE DEVELOPMENT THIS
AFTERNOON/EVENING. THERE ARE STILL A FEW AREAS OF LOW CEILINGS AND
FOG BUT AS THE RAIN MOVES IN THAT IS BECOMING LESS OF AN AVIATION
ISSUE.
