.DISCUSSION...

EXPECT A WARM AND SUNNY DAY WITH A HIGH NEAR 70. THE WINDS WILL BE
LIGHT AT 5 TO 10 MPH FROM THE SOUTHEAST NEAR BURN TIME...BUT BECOME
VERY LIGHT AND VARIABLE BY THE LATE AFTERNOON. ANTICIPATE A VERY
DRY MINIMUM RH BELOW 20 PERCENT BY MID AFTERNOON. DO NOT THINK IT
WILL GET BELOW 10 PERCENT DUE TO THE LACK OF WIND FLOW TO DRAW DOWN
THE VERY DRY AIR FROM ALOFT....DESPITE THE HIGH MIXING HEIGHTS.
SMOKE DISPERSION WILL BE GOOD...WITH THE HIGH MIXING HEIGHTS MAKING
UP FOR THE LACK OF WIND FLOW.
