.DISCUSSION...Increasingly strong and dry southwesterly winds will spread
over the burn area today, increasing the overall threat of
critical fire weather conditions. Humidity is expected to bottom
out in the low- to mid-teens with winds peaking around 25-30 mph. Winds
will remain elevated through the overnight hours and help to
contribute to poor humidity recoveries. Winds continue to increase
through Monday afternoon ahead of an approaching dry cold front,
where gusts may peak around 35-40 mph before the cold front arrives.
The most likely time of arrival of the cold front looks to fall
between 1600 and 2000. Winds will shift out of a northwesterly
direction as the front progresses over the burn and will remain
out of the northwest through the overnight hours. Humidity
recoveries are likely to increase alongside the cooler
temperatures, however, the dry nature of the front will create
continued dry conditions heading into Tuesday.
