.DISCUSSION...

Cumulus buildups will continue around the fire through 1600 hrs 
with a small threat for light rain.  Rain amounts will vary from 
a trace to 0.01".  Trends in radar and satellite between 
1200-1245 pdt have been for a decreasing rain trend over the 
fire.  Cells have been building east of the fire.  These cells are 
drifting to the east away from operations.  This leads to moderate 
confidence that any additional rainfall will be very light. 
No lightning is expected with activity over the fire.


If conditions become unrepresentative, contact the National Weather
Service.
