.DISCUSSION...
TEMPERATURES WILL REMAIN ABOVE NORMAL THROUGH FRIDAY WITH MAINLY
SUNNY SKIES AND MINIMUM RELATIVE HUMIDITY VALUES FALLING BELOW
30 PERCENT.  THE DRY WEATHER THE PAST MONTH HAS CAUSED FUEL
MOISTURE TO FALL INTO THE 7-8 PERCENT RANGE.  THE LIMITING
FACTOR FOR WILDFIRE GROWTH TOMORROW WILL BE THE WINDS WHICH ARE
EXPECTED TO BE 7 MPH OR LESS.  RELATIVELY LIGHT WINDS AND LOW
MIXING HEIGHTS WILL CAUSE POOR VENTILATION RATES TOMORROW.
