CURRENT SATELLITE LOOP SHOWS CLEAR SKIES ACROSS THE THE STATE THIS
MORNING. A LARGE HIGH PRESSURE RIDGE HAS SETTLED IN OVER THE
SOUTHEASTERN STATES AND WILL CONTINUE TO KEEP GA PRECIPITATION FREE
THROUGH THE SHORT TERM. TEMPS ARE BEGINNING TO REBOUND WITH HIGHS

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
THERE IS SOME DISAGREEMENT WITHIN THE LONG RANGE MODELS ON
TEMPS/CLOUD COVER INTO THE WEEKEND.

OLD FRONTAL BOUNDARY SETS UP ACROSS TN AND THE CAROLINAS THROUGH THE
WEEKEND. SEVERAL SHORTWAVES/LOW PRESSURE SYSTEMS MOVE EAST AND
INTERACT WITH THE BOUNDARY. POPS SHOULD BE HIGHEST UP
NORTH...NEAREST THE ENERGY/BOUNDARY AND HAVE TRIED TO REFLECT THIS
IN THE GRIDS. OVERALL...CURRENT GRIDS HAD THE TREND HANDLED WELL AND
ONLY MADE VERY MINOR CHANGES.

THE MODEL DIFFERENCES ARE CENTERED MORE AROUND SKY COVER/MAX TEMPS.
THE MODELS ARE FORECASTING A GOOD DEAL OF CLOUDS ACROSS THE CWFA
WELL INTO THE WEEKEND...THUS RESULTING IN LOWER MAX TEMPS. NOT TOO
CONFIDENT THAT THE COOLER TEMPS/THICKER CLOUD COVER WILL EXTEND INTO
THE CENTRAL/SOUTH PARTS OF THE CWFA SO HAVE BUMPED UP TEMPS/REDUCED
CLOUD COVER FOR THOSE AREAS. ALSO BUMPED UP TEMPS ACROSS THE NORTH
INTO THE WEEKEND. THE BOUNDARY SHOULD BEGIN TO RETREAT NORTHWARD AS
A COLD FRONT MOVES INTO THE CENTRAL US.

THE NEXT FRONTAL BOUNDARY LOOKS TO IMPACT NORTH AND CENTRAL GEORGIA
WEDNESDAY INTO THURSDAY.
