.DISCUSSION...The region will remain locked in a persistent
weather pattern through much of the week. Expect relatively
consistent winds at the fire through the weekend, with generally
West-Northwest winds during the early morning and afternoon,
shifting more Southwest overnight. Winds could become more gusty
Monday onward, however, as the winds aloft become more amplified,
but RH recoveries are expected to improve as cooler air starts to
filter into the region.
