.DISCUSSION...

The big issue relating to fire weather will center around the very
light and variable wind. Expect that wind speeds will for the most
part remain at or below 10 mph through Monday. At times the wind will
be flat out calm given the high pressure area centered right over the
forecast area. It is important to realize that when the wind is this
light it will be a bit shifty with light breezes randomly coming out
of different directions.

For the Cozad area the wind will be more predominantly out of the
north or east this morning, and then east or south this afternoon,
and then south or west tonight. But again given that the wind is
so light it will likely be rather variable and could come from
about any direction from time to time. Can not rule out a very
slight chance of a light rain shower today or tonight, but in the
small chance that it does rain it would likely be short in
duration and hardly measure if at all.
