AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
620 AM EST FRI DEC 25 2009

.AVIATION...TYS WIND SENSOR STILL QUESTIONABLE, SO OBSERVATIONS 
BEING AUGMENTED. HOPEFULLY THIS WILL BE REMEDIED TODAY. LARGE CLOUD 
SHIELD WITH MODERATLY HUMID (ALBEIT COOL) AIR MOVING EASTWARD OVER 
AREA. THE BACK EDGE OF THE RAIN IS MOVING THROUGH SOUTHEAST TN NOW. 
SLOW BUT SURE PROGRESS WILL KEEP SOME RAIN IN ALL THREE TAF SITES 
FOR TWO TO THREE HOURS MORE, BUT IT IS WEAKENING AS IT MOVES EAST. 
CIGS AND VSBYS ARE GENERALLY MVFR WITH RAIN AND "LOW" VFR WHEN IT 
DOES NOT RAIN. THE ISSUE IS THE WIND. PUBLIC REPORTS OF GUSTS TO 
NEAR 50 MPH AND EVEN AWOS REPORTS IN SW NC OF 51 KTS HAVE COME IN TO 
THE OFFICE. MOUNTAIN TOWER DATA NOT AVAILABLE BUT SUSPECT EXTREMELY 
HIGH WINDS THERE. HAVE NOT FORECAST LLWS DUE TO SFC WINDS PICKING UP 
SPEED AND THERE BECOMING LESS OF A SHEAR FACTOR IN THE WIND SPEED 
AND DIRECTION OFF THE SURFACE. SOME PIREPS BY LARGE AIRCRAFT OF TURB 
BELOW 7000 FEET. 

DIMINISH CIGS SOMEWHAT THROUGH DAY AND SLACKEN THE WINDS LATER THIS 
AFTN AND EVENING.
