THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 554
CONTINUES.

STORMS WILL BEGIN TO SPREAD EAST AND SOUTH OF WW 554 SHORTLY... BUT
ANOTHER WW IS NOT ANTICIPATED.

A LOW/MID-LEVEL CYCLONIC CIRCULATION ASSOCIATED WITH THE ONGOING
MESOSCALE CONVECTIVE SYSTEM IS GRADUALLY TURNING EASTWARD...AND WILL
CROSS THE OHIO RIVER INTO NORTH CENTRAL KENTUCKY DURING THE NEXT
COUPLE OF HOURS.  WITH SOUTHWESTERLY ELEVATED MOIST INFLOW BECOMING
CUT-OFF BY CONVECTION ON THE TRAILING SURGING OUTFLOW...AND EASTERLY
NEAR SURFACE INFLOW EMANATING FROM A COOLER AND MORE STABLE BOUNDARY
LAYER AIR MASS ACROSS THE BLUEGRASS...CONVECTION NEAR THIS FEATURE
PROBABLY WILL CONTINUE TO WEAKEN.

MEANWHILE...CONVECTION ON THE LEADING EDGE OF THE TRAILING OUTFLOW
BOUNDARY...WHICH IS NOW RAPIDLY PROGRESSING INTO/THROUGH THE MIDDLE
TENNESSEE BORDER AREA...HAS ALREADY WEAKENED CONSIDERABLY DURING THE
PAST HOUR OR SO.  THIS GENERAL TREND IS EXPECTED TO CONTINUE AS THE
GUST FRONT ADVANCES SOUTH OF THE STRONGER DEEP LAYER MEAN FLOW...AND
LOW-LEVEL INFLOW BECOMES PROGRESSIVELY WEAKER.
