DISCUSSION
 
 
AS A COLD FRONT PUSHES THROUGH CENTRAL FL THIS MORNING, CONDITIONS  
REMAIN CONDUCIVE FOR FOG TO LINGER THROUGH MID-MORNING. AS THE SUN  
WARMS THE GROUND AND COOLER, DRIER AIR FILTERS IN, THIS WILL QUICKLY  
DIMINISH. THE DRIER AIR FILTERING IN WILL POTENTIALLY ALLOW RH VALUES  
TO DIP INTO THE LOW 30S FOR PORTIONS OF THE AFTERNOON. HOWEVER, LOW  
ERCS AND FAIRLY LIGHT WINDS DO NOT WARRANT RED FLAG CONDITIONS AT  
THIS TIME. A SIMILAR STORY IS EXPECTED FOR SUNDAY BEFORE MOISTURE  
LEVELS BEGIN TO REBOUND ON MONDAY.
