.Discussion...
Dry weather will continue through the holiday weekend under high
pressure. Minimum relative humidity levels should drop into the 30
to 40 percent range for much of the area each afternoon, but wind
gusts are largely expected to remain at 15 MPH or less, limiting
fire spread potential. The next chance of rain does not occur
until Wednesday into Thursday.
