.DISCUSSION...
ALTHOUGH RELATIVE HUMIDITIES ARE EXPECTED IN THE 26 TO 30 PERCENT
RANGE...CONFIDENCE IS MEDIUM IN THIS. IF THE ATMOSPHERE MIXES MORE
THAN EXPECTED PRIOR TO THE HIGHER DEW POINTS ADVECTING INTO
FANNIN/MURRAY COUNTY...HUMIDITIES COULD DROP TO 25 PERCENT. IF
THEY DO...THIS WILL BE BRIEF. HOWEVER AT THIS TIME THERE IS ENOUGH
CONFIDENCE THAT THE FORECAST IS KEEPING HUMIDITIES ABOVE 25 PERCENT.

WIND SHIFTS ARE NOT EXPECTED. GENERAL FLOW IS EAST TO SOUTHEAST AROUND
5 MPH...HOWEVER TOPOGRAPHY SHOULD TAKE OVER AND SHOULD SEE UPSLOPE FLOW
BY NOON WITH DOWNSLOPE DEVELOPING THIS EVENING.
