THIS IS DUE TO A FRONTAL BOUNDARY THAT IS IN THE AREA. THE WINDS  
AT TIMES MIGHT BE LIGHT AND VARIABLE IF THE FRONT STALLS OVER THE  
BURN SITES. WINDS ARE EXPECTED BY LATE MORNING TO SHIFT BACK OUT  
OF THE SOUTHEAST AS THE FRONT RETREATS NORTH. ISOLATED  
THUNDERSTORMS WILL BE POSSIBLE TONIGHT GIVEN THAT THE FRONTAL  
BOUNDARY WILL BE NEAR THE BURN SITE. ONE STORM CURRENTLY  
DEVELOPING ABOUT 25 MILES WEST NORTHWEST OF THE BURN SITE. MOVING
