NATIONAL WEATHER SERVICE MEMPHIS TN

.DISCUSSION...

COLD FRONT EXTENDS FROM SOUTHWEST KENTUCKY THROUGH NORTHWEST
TENNESSEE INTO NORTHEAST TEXAS. EARLIER SHOWERS HAD FORMED NORTH OF
THE FRONT AND HAVE MOVED INTO MIDDLE TENNESSEE. THUNDERSTORMS ARE
NOW STARTING TO DEVELOP SOUTH OF THE FRONT. WITH WARM ATMOSPHERE
SOUTH OF THE FRONT CANT RULE OUT SOME SEVERE STORMS. CURRENT
FORECAST HAS A GOOD HANDLE ON THE SITUATION SO NO CHANGES ARE
PLANNED AT THIS TIME.
