.DISCUSSION...

EXPECT A WARM AND SUNNY DAY WITH A HIGH NEAR 72. 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.
