PLEASANT WEATHER EXPECTED FOR THE SHORT TERM. CLOUDS THAT LINGERED
ACROSS NORTH GEORGIA MUCH OF THE MORNING HAVE DISSIPATED AND SKIES
ARE EXPECTED TO REMAIN CLEAR OVERNIGHT. NORTHWEST FLOW ACROSS THE
AREA ALOFT WHILE HIGH PRESSURE CENTERED OVER THE GREAT LAKES REGION
CONTINUES TO DOMINATE AT THE SFC. WITH THE SFC HIGH INFLUENCING THE
CWA THROUGH THE SHORT TERM...THE AREA WILL REMAIN DRY. A WEAK
SHORTWAVE MOVES THROUGH THE TENNESSEE VALLEY SATURDAY NIGHT AND
APPROACHES NORTH GEORGIA BY LATE SATURDAY NIGHT HOWEVER NO PRECIP IS
EXPECTED WITH THIS SHORTWAVE AND THE MAIN IMPACT WILL BE AN INCREASE
IN MID LEVEL CLOUDS.

OVERNIGHT LOWS WILL BE WELL BELOW NORMAL TONIGHT AND SATURDAY NIGHT.
ALTHOUGH AHN LOW TEMP FORECAST FOR TONIGHT IS CLOSE TO A RECORD
MINIMUM TEMPERATURE...MCN IS THE ONLY PLACE FORECAST TO TIE THE
RECORD MIN. FOR SATURDAY NIGHT THOUGH...TEMPERATURES WILL BE
SLIGHTLY WARMER AND AM NOT FORECASTING ANY RECORD BREAKING LOWS. MAX
