.DISCUSSION...
/ISSUED 1041 AM CDT FRI SEP 27 2013/
HIGH PRESSURE BUILDING ACROSS THE EASTERN CONUS IS PROVIDING A MOSTLY
CLEAR MORNING ACROSS THE TENNESSEE VALLEY. MORNING LOWS THAT DIPPED
INTO THE MID 50S TO AROUND 60 DEGREES ARE GRADUALLY WARMING BACK INTO
THE LOWER 70S UNDER THE MORNING SUN...WITH ANY VALLEY FOG QUICKLY
DISSIPATING WITH THE HEATING OF THE DAY. WITH EAST/SOUTHEASTERLY
FLOW DEVELOPING ACROSS THE REGION...A GRADIENT IN MOISTURE CAN BE
SEEN ACROSS THE SOUTHEAST. MID 60 DEWPOINTS ARE POOLING NORTHWARD
THROUGH CENTRAL MISSISSIPPI WHILE MID 50S DEWPOINTS ARE SPREADING
WESTWARD AROUND THE BASE OF THE APPALACHIANS. THIS DRY AIR WILL
CONTINUE TO SPREAD ACROSS THE TENNESSEE VALLEY TODAY...BUT HAD TO
ADJUST DEWPOINT GRIDS UPWARDS SLIGHTLY TO ACCOUNT FOR A SLIGHTLY
SLOWER WESTWARD EXPANSION OF 50S DEWPOINTS. OTHERWISE...TEMPS THIS
MORNING ARE RUNNING JUST A DEGREE OR TWO COOLER THAN THE SAME TIME
YESTERDAY...SO EVEN WITH THE GREATER SOLAR INSOLATION EXPECTED
TODAY...ANTICIPATE HIGHS TO TOP OUT NEAR THE LOW 80S SEEN YESTERDAY.
MADE A FEW MINOR MODIFICATIONS TO THE TEMP TREND FOR THE AFTERNOON TO
KEEP MAX TEMPS BELOW 85.
