.DISCUSSION...
Look for mostly sunny skies today at the fire site. Winds will be
under 10 mph from northwest/west early today turning more
southwesterly by late morning. Winds then turn more east/northeast
in the afternoon at 6-11 mph which continues overnight into
Sunday. Sunday will be a little warmer, with RH readings in the
lower 20s again. Winds will turn to the southwest Sunday. There is a
slight chance of a shower or thunderstorm near the fire by Sunday
evening. Any storms will be mostly garden variety, but an isolated
storm could develop that is capable of strong winds Sunday
evening. BT
