.DISCUSSION...
Winds are still expected to be very light, but a weak cold front will
be moving into south central or southeastern Oklahoma in the morning
hours so the wind direction at ignition time will depend on where this
front is located. Feel free to submit another spot or give the office
a call in the morning to coordinate on the latest data if the wind
direction is important to the burn. Regardless of where this front is
located in the morning, winds will trend to becoming southeasterly or
easterly in the afternoon, but still remain relatively light. Smoke
dispersal will be fair at best with the expected light winds.
