.DISCUSSION...A notable uptick in south to southwest winds are expected
over the fire area today, with gusts increasing after about 1100.
Moisture will remain in place over the area today, allowing for
isolated shower and thunderstorm development after 1300. While the
chance of seeing a cell move over the fire is low (10-15%),
nearby cells may still push outflow winds over the fire. High
level cloud cover will reduce the overall solar radiation over the
fire from the mid-morning through the late afternoon, with skies
clearing around 1600. A significant drying is expected on
Wednesday, with minimum relative humidity values dropping by as
much as 20 percent as compared to today. In addition to the stout
drop in humidity, southwest winds are also expected to increase
over the area, with peak speeds approaching sustained speeds up to
25 mph and gusts to around 35 mph during the late morning and
early afternoon hours on Wednesday, shifting to a west to
northwest wind in the mid-afternoon (around 1500). That said,
winds are expected to begin increasing during the overnight hours
from today into tomorrow.
