.DISCUSSION...
/ISSUED 1050 AM CDT WED MAY 6 2015/
SURFACE AND UPPER LEVEL AREA OF HIGH PRESSURE IS STILL CENTERED OVER
THE TENNESSEE VALLEY THIS MORNING. THIS AND CLEAR SKIES ARE ALLOWING
FOR A VERY QUICK RISE IN TEMPERATURES...WITH TEMPERATURES AT 10 AM IN
THE LOWER 70S TO MID 70S IN MOST LOCATIONS.

A WEAK TROUGH AXIS ALSO EXTENDS SOUTHEAST FROM THE MID-ATLANTIC AREA
INTO EXTREME SOUTHWESTERN VIRGINIA AND EASTERN KENTUCKY. THIS IS
CREATING SOME CLOUD COVER OVER KENTUCKY THIS MORNING. MODELS HAVE
THIS BOUNDARY AND THE MOISTURE ASSOCIATED WITH IT INITIALIZED TOO FAR
SOUTH AT THIS TIME. SOME MESOSCALE MODELS BRING SOME OF THE MOISTURE
SOUTH INTO SOUTHERN MIDDLE TN IN THE FORM OF PARTLY CLOUDY CONDITIONS
THIS AFTERNOON. BELIEVE BASED ON CURRENT POSITION OF THE BOUNDARY
THEY ARE OVERDOING IT. SO ONLY GOING MOSTLY SUNNY THERE AND FOR MUCH
OF THE FORECAST AREA. THE EXCEPTION TO THIS WILL BE NW ALABAMA...AS
MOISTURE SEEN IN VISIBLE SATELLITE IMAGERY OVER CENTRAL ALABAMA IS
EXPECTED TO BE TRANSPORTED IN NW ALABAMA THIS AFTERNOON. THEREFORE
INCREASED CLOUD COVER THERE THIS AFTERNOON TO PARTLY CLOUDY.

DUE TO WARM START AND ONLY PARTLY CLOUDY CONDITIONS EXPECTED THIS
AFTERNOON AT WORST...RAISED HIGH TEMPERATURES TO THE 80 TO 85 DEGREE
RANGE IN MOST LOCATIONS. A FEW WARMER SPOTS SUCH AS HUNTSVILLE...NW
AL...AND ATHENS COULD REACH 85 TO 87 DEGREES. TWEAKED DEWPOINTS TO
ALLOW FOR MINIMAL MIXING EAST OF I-65 THIS AFTERNOON.
