.DISCUSSION...
Relative Humidity will continue to rise tonight with winds
quickly easing as well. Much lighter winds along with somewhat
higher humidity values are forecast on Friday, greatly limiting
the fire weather threat. While minimum RH may still reach down
close to 30-40 percent during `peak daytime heating` Friday
afternoon, winds of mainly 5 to 10 mph will preclude the need
for even another Special Weather Statement on Friday.
