.DISCUSSION...
/ISSUED 1101 AM CDT THU MAY 23 2013/
THE CURRENT SHORT TERM GRIDS ARE IN GOOD CONDITION THIS MORNING WITH
NO SIGNIFICANT CHANGES REQUIRED AT THIS TIME. LATEST VISIBLE
SATELLITE AND SURFACE OBSERVATION DATA INDICATE A WEAK COLD FRONT
CURRENTLY BISECTING THE FORECAST AREA. ALTHOUGH CLOUD COVER
PERCENTAGES WERE INCREASED TO THE EAST OF THE COLD FRONT FOR THE
REMAINDER OF THE MORNING PERIOD...WEAK CONVERGENCE AND LIMITED
MOISTURE WILL RESULT IN VERY LITTLE SHOWER AND THUNDERSTORM ACTIVITY.
A SLIGHT CHANCE OF SHOWERS AND STORMS WILL BE RETAINED FOR SOUTHERN
MIDDLE TENNESSEE AND EXTREME NORTHEAST ALABAMA THIS AFTERNOON...AS
UPSLOPE FLOW STRENGTHENS IN THE ELEVATED TERRAIN ACROSS THIS REGION.
HIGH TEMPERATURES/DEWPOINTS AND WINDS LOOK GOOD AT THIS TIME.
