FOR EVENING DISCUSSION.  
 

 
   
DISCUSSION
 
 
CLOUD COVER HAS BEEN PERSISTENT THIS EVENING ACROSS THE AREA. LESS  
COVERAGE IN THE SOUTHERN MOST COUNTIES HAS ALLOWED TEMPERATURES TO  
FALL A LITTLE FURTHER THAN PREVIOUSLY FORECAST, SO WE COULD SEE  
SOME LOW TEMPERATURES EARLY SUNDAY MORNING DIP CLOSE TO FREEZING  
IN THOSE AREAS. HAVE UPDATED THE LOW TEMPERATURE FORECAST TO  
REFLECT THIS. STILL EXPECTING LIGHT RAIN TO MOVE INTO THE AREA  
BETWEEN 10Z AND 12Z AND SPREAD EAST THROUGHOUT THE MORNING HOURS.  
TEMPERATURES WILL RISE INTO THE MID TO UPPER 40S FOR EVERYONE,  
MAKING IT A SOGGY COOL DAY ACROSS THE MID STATE.

18Z TAF DISCUSSION.  
 
AN UPPER LEVEL HIGH PRESSURE RIDGE WILL MOVE FROM WEST TO EAST  
ACROSS TN THIS AFTERNOON AND TONIGHT. SO, EXPECT VFR CONDITIONS  
TO CONTINUE AT EACH TAF SITE THE REST OF TODAY AS WELL AS TONIGHT  
WITH MAINLY CIRRUS CLOUDS OVER THE REGION. SOUTH AND SOUTHWEST  
BREEZES WILL BE JUST A TAD GUSTY THIS AFTERNOON BUT WILL  
DIMINISH BEFORE 00Z.  
 
RAIN CHANCES WILL INCREASE QUICKLY EARLY SUNDAY MORNING AS A  
WEAKENING TROUGH MOVES OUT OF TX AND TOWARD THE MS/OH VALLEY  
REGION. ALTHOUGH THE SHOWERS SHOULD LAST ONLY A FEW HOURS AND  
REMAIN FAIRLY LIGHT, CEILINGS AND VISIBILITIES SHOULD DROP TO MVFR  
AT EACH SITE. RAIN CHANCES SHOULD END BY 18Z SUNDAY.
