.DISCUSSION...

Good morning Nathan!

Looks like an excellent day to burn. We do have a Fire Danger
Statement in place for today for a combination of gusty winds and
low RH. We`re expecting your min RH values to drop to between
23-27% this afternoon with NW winds between 10 and 15 mph. A few
gusts could reach as high as 25 MPH as plenty of sunshine will
allow us to mix into some drier/windy conditions aloft.

Following the morning after the burn we aren`t seeing any signs of
fog, but smoke dispersion and ventilation will be poor due to
weakening of surface/transport winds. Winds will pick up slightly
after noon on Friday to help clear smoke from today`s burn out.

We`ll continue to monitor Brender RAWS and keep an eye on any
deviation from the forecast below. If you have any additional
questions or concerns, please feel free to give us a call.
