SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
CURRENT RADAR LOOP SHOWS SHOWERS ACROSS MOST OF NORTH AND CENTRAL
GEORGIA. CURRENTLY THE MOST RAIN HAS FALLEN ACROSS CENTRAL GA WITH
50 TO 1 INCH TOTALS. THIS RAIN IS EXPECTED TO CONTINUE THROUGH
TONIGHT WITH THE MAIN LOW CENTER CURRENTLY OVER THE NORTHERN
GULF/NORTHERN AND CENTRAL FL. THIS LOW WILL SLOWLY TRACK
NORTHEASTWARD AND DEEPEN SLIGHTLY AS IT IS EXPECTED TO BE JUST OFF
THE CAROLINA COAST BY 18Z THU. ONCE THIS LOW PULLS AWAY FROM THE
CAROLINA COAST THU NIGHT...HIGH PRESSURE BEGINS TO BUILD IN FROM
THE SOUTHERN PLAINS WITH DRY NORTHERLY FLOW SETTING UP ACROSS THE
STATE. THIS RIDGE STAYS ACROSS THE AREA THROUGH THE SHORT TERM
WITH ANOTHER FRONT MOVING IN BY SUN.
LONG TERM /SATURDAY THROUGH WEDNESDAY/...
MODELS ARE IN GOOD AGREEMENT WITH THE NEXT FRONTAL SYSTEM THAT
SWINGS THROUGH ON SUN. THIS SYSTEM LOOKS LIKE IT WILL BEGIN
SPREADING SHOWERS INTO THE STATE EARLY SUNDAY MORNING WITH THE BACK
EDGE MOVING OUT OF THE AREA BY 18Z SUN. THERE IS MINIMAL INSTABILITY
WITH THIS SYSTEM SO WILL CONTINUE WITH ISOLATED THUNDER WORDING IN
THE FORECAST. THERE IS ALSO A 50KT LLJ AND STRONG UPPER SUPPORT
DURING DAYTIME HEATING. STRONG HIGH PRESSURE AND A COOL/STABLE NW
FLOW BEHIND THE FRONT WILL BRING MUCH DRIER CONDITIONS FOR THE STATE
THROUGH NEXT WED.
