DISCUSSION
A FEW FORECAST FACTORS HAVE CHANGED SINCE THE LAST PROVIDED
UPDATE. FIRST, WARMER TEMPERATURES AND LOWER HUMIDITY ARE NOW
EXPECTED, WITH MEDIUM-HIGH (40-60%) CONFIDENCE IN RELATIVE
HUMIDITY FALLING BELOW THE 15% THRESHOLD THIS AFTERNOON.
ADDITIONALLY, IT NOW APPEARS AS THOUGH A WEAK SURFACE FRONT SHOULD
REMAIN TO THE NORTH OF THE BURN SITE TODAY SUCH THAT A
PREDOMINATE SOUTH-TO-SOUTHWEST WIND DIRECTION WILL REMAIN INTO
THIS EVENING.
THE COMBINATION OF VERY LOW HUMIDITY AND A BREEZY SOUTH/SOUTHWEST
WIND WILL CONTRIBUTE TO ELEVATED FIRE WEATHER CONDITIONS THIS
AFTERNOON, WITH SIMILAR CONDITIONS EXPECTED ON THURSDAY.
