.DISCUSSION...
A decaying line of light rain with a few embedded lightning
strikes will continue to diminish as it moves to the east. At this
time, it does not appear as though this precipitation will make
it to the burn site, although a brief period of light rain thru
the early afternoon cannot be completely ruled out. Any shower
activity would carry a threat of brief erratic winds although
again, this appears a relatively low threat and would end by 2 pm.

Otherwise, it appears winds will remain south or southeasterly at
15-20 mph through the afternoon with some gusts in the 25-30 mph
range. Minimum afternoon relative humidity values should be the
45-50 percent range.
