/ISSUED 940 PM CDT SAT MAY 2 2015/
CLEAR SKIES ABOUNDED ACROSS THE CENTRAL TENNESSEE VALLEY THIS
EVENING...COURTESY OF HIGH PRESSURE IN PLACE OVER THIS REGION.
9 PM TEMPERATURES HAVE COOLED INTO THE MID 50S TO MID 60S WITH
LIGHT AND VARIABLE WINDS. THE RADAR AND VELOCITY DATA INDICATED
AN INVERSION HAS FORMED ALOFT...WITH SOMEWHAT HIGHER WINDS IN THE
10-20KT RANGE FROM THE SOUTH ABOVE THE BOUNDARY LAYER.

ONLY A FEW HIGH ALTITUDE CLOUDS WERE HEADED IN AN ESE DIRECTION
FROM THE GREAT PLAINS. THIS WILL KEEP A FEW CLOUDS IN THE FORECAST
FOR THE OVERNIGHT...THUS MOSTLY CLEAR WORDING WILL HOLD. WITH
GENERALLY CLEAR SKIES...OVERNIGHT LOW TEMPERATURES WILL COOL INTO
THE LOWER 50S MOST SPOTS. PLENTIFUL SUN EARLIER TODAY HELPED TO
DRY THE LOWER ATMOSPHERE MORE THAN WAS THE CAST YESTERDAY. DESPITE
THAT...SOME PATCHY FOG COULD FORM BEFORE DAYBREAK SATURDAY. GIVEN
SPARSITY OF EXPECTED FOG AND ONLY SHORT-TIME VISIBILITY REDUCTIONS
INTO THE MVFR RANGE...WILL HOLD OFF ON ADDING FOG THIS ISSUANCE.

DID MAKE A FEW TWEAKS TO OVERNIGHT LOW TEMPERATURES...WHICH WON`T
CHANGE THE GENERAL FORECAST THINKING. UPDATED DIGITAL TEXT
