DISCUSSION...SURFACE MAP AT 19Z SHOWS COLD FRONT EDGING ITS WAY
INTO KENTUCKY, WITH AN AREA OF ACTIVE WEATHER IN WEST TENNESSEE
INCHING ITS WAY TOWARD THE TENNESSEE RIVER. TEMPERATURES ACROSS
THE MID STATE HAVE RISEN WELL INTO THE 80'S, WITH DEW POINTS
MAINLY IN THE MID 50'S TO AROUND 60. LATEST WRF MODEL SHOWS THE
FRONT ENTERING MIDDLE TENNESSEE AROUND 02Z, WITH THE BULK OF THE
