.DISCUSSION...

Good afternoon,

Winds will start out light tomorrow morning before gradually
picking up out of the southeast. Not much in the way of wind speed
to talk about though as surface winds are not expected to exceed 7
mph during the day. Transport winds will also be light at less
than 10 mph. This does look like it will have smoke running
parallel and eventually intersecting Cyler road depending on where
you initially fire.

Minimum RH values will fall to around 40% tomorrow afternoon
before we start a trend that will increase relative humidity
heading into the weekend. Complete overnight RH recovery
Wednesday into Thursday combined with light winds will likely
result in some light fog in low lying areas, but widespread fog is
not expected.

We`ll have the morning shift run the spot again and take another
look for you, but feel free to give us a call if you have any
other questions.
