.DISCUSSION...
/ISSUED 930 PM CST SAT DEC 20 2014/
AFTER A LONG BOUT OF CLOUDY SKIES FOR ALMOST THE PAST WEEK...MOST OF
THE TENNESSEE VALLEY GOT A WELCOMED CHANGED AS THE SUN MADE AN
APPEARANCE FOR THE LAST DAY OF AUTUMN (WITH THE WINTER SOLSTICE AT
503 PM SUN AFTERNOON). HOWEVER...PESKY STRATUS HELD FIRM OVER OUR
EASTERN AREAS...WITH PORTIONS OF FAR NE ALABAMA (EASTERN JACKSON/
MARSHALL...AND MOST OF DEKALB COUNTIES STAYING IN THE CLOUDS - DURING
THE DAYLIGHT HOURS). AS OF THIS WRITING...THE STRATUS HAS MOVED EAST
OF NE AL...WITH THE STRATUS HANGING TOUGH ALONG THE NE AL/NW GA
BORDER.

THE CLOUD DECK NOW EAST OF OUR NE GROUP HAS RESULTED IN TEMPERATURES
RAPIDLY COOLING...NOW INTO THE LOWER 30S IN FT PAYNE AND SCOTTSBORO.
THIS OF COURSE REQUIRED UPDATES FOR THE OVERNIGHT PERIOD...MAINLY TO
LOWER LOW TEMPERATURES FOR OUR EASTERN AREAS. ALSO MADE OTHER MINOR
TEMP/DEWPOINT ADJUSTMENTS ELSEWHERE. CLEARED SKIES FOR THE EASTERN
AREAS TO FOR THE OVERNIGHT. GIVEN THE EARLIER CLOUD COVERAGE HAS
HELPED THOSE AREAS RETAIN LOWER LEVEL MOISTURE VALUES...INTRODUCED
PATCHY FOG LATE TONIGHT FOR THE WIND SHELTERED AND LARGE BODY OF
WATER AREAS OF NE AL. THOSE UPDATES IN THE AFM/PFM AND GRIDS HAVE
BEEN SENT.

MIST/FOG AROUND DAYBREAK IS POSSIBLE...ESPECIALLY ACROSS NE AL
IN THE MORE WIND SHELTERED LOCATIONS. VFR WEATHER OTHERWISE IS
EXPECTED THROUGH THE PERIOD...WITH LIGHT NE WINDS BECOMING SE IN
THE AFTERNOON. A SYSTEM DEVELOPING ALONG THE GULF COAST WILL MOVE
TOWARD THE PIEDMONT...BRINGING INCREASING CLOUDS IN THE LATER
AFTERNOON AND EVENING. HAVE ADDED LIGHT RAIN AT KHSV SUN EVENING
WITH VFR CIG/VIS VALUES EXPECTED.
