.DISCUSSION...
/ISSUED 1049 AM CST SAT FEB 6 2016/
A WEAK UPPER LOW OVER THE AL/GA LINE CONTINUES TO PRODUCE PARTLY TO
MOSTLY CLOUDY CONDITIONS ACROSS MUCH OF NORTHERN AL AND SOME OF
NORTHERN GA. MODELS SLOWLY PUSH THIS FEATURE EASTWARD AS THE DAY
GOES ON. THIS MORNING...PRIMARILY NEUTRAL TO SLIGHTLY COLD AIR
ADVECTION WILL CONTINUE EAST OF I-65. FURTHER WEST SOME WEAK WARM AIR
ADVECTION MAY START AROUND NOON...AND BECOME SLIGHTLY STRONGER AS
FLOW FROM THE NORTH ADVECTS SLIGHTLY WARMER AIR SOUTHWARD INTO
NORTHERN AL. ALTHOUGH SOME MOSTLY SUNNY CONDITIONS CAN BE SEEN IN
LATEST SATELLITE IMAGERY OVER CULLMAN COUNTY...PORTIONS OF NW
AL...AND SOUTHERN MIDDLE TN...EXPECT A THICK ENOUGH LAYER OF HIGH
CLOUDS TO QUICKLY DEVELOP EVERYWHERE BY NOON FOR PREDOMINANTLY MOSTLY
CLOUDY CONDITIONS. DUE TO EXTREMELY DRY BOUNDARY LAYER CONDITIONS...NO
PRECIPITATION IS EXPECTED DESPITE WEAK LIFT NEAR THE UPPER LOW.

BASED ON CURRENT TEMPERATURES IN THE 40 TO 45 DEGREE RANGE WEST OF
I-65 AND IN LINCOLN COUNTY (TN)...THINK PREVIOUS HIGHS WERE JUST A
TAD LOW AND RAISED THEM SLIGHTLY. THIS IS MAINLY DUE TO A SLIGHT
DELAY IN THICKER AND MORE WIDESPREAD CLOUD COVER THIS MORNING.
FURTHER EAST...SINCE COLD AIR ADVECTION AND THICKER CLOUDS WILL HANG
ON TOUGHER MUCH OF THE DAY...TWEAKED HIGHS INTO THE MID TO UPPER 40S.
LOWERED DEWPOINTS A BIT THIS MORNING INTO THE EARLY AFTERNOON...AS
SOME DRY AIR ALOFT WILL LIKELY BE MIXED DOWN TO THE SURFACE GIVEN
STEEP LOW LEVEL LAPSE RATES. OTHERWISE NO OTHER CHANGES MADE TO THE
FORECAST.
