.DISCUSSION...

The burn site will start out with southwest winds around 10 mph
early this morning. Wind direction should gradually turn to the
west this afternoon, remaining around 10 mph. A sharper wind shift
to the northwest is expected with the passage of a cold front
this evening. Some gustier winds and light rain are likely with
the frontal passage this evening.

Relative humidity early this morning is forecast around 70 to 75
percent. This should steadily decrease from mid morning to early
afternoon, settling around 40 to 45 percent in the mid to late
afternoon. A high temperature in the mid 60s is forecast this
afternoon, but it could be slightly cooler (and with a slightly
higher minimum humidity) at the burn site due to it being
surrounded by water.
