.DISCUSSION...

Winds today will predominantly be out of the west/northwest, with little
to no variation in wind direction expected today. Winds do look to remain
rather light at around 5 mph, with gusts up to 10-15 mph, with most gusts
likely being on the lower end of that threshold. Rain showers early this
morning are expected to diminish throughout the mid morning hours as the
frontal boundary finally pushes far enough south that enough dry air will
have pushed into the region. Minimum RH values are expected to drop to
around 34% by this afternoon at the peak of boundary layer mixing. The
westerly winds today may aid in pushing the fire uphill along the face
of the mountain where the burn is located. Overall, outside of the
early morning rain chances, there are no other concerns at this time.
