.DISCUSSION...

Cloud cover will be mostly sunny tomorrow afternoon allowing for
lower RHs than previous days with warmer temperatures. With this,
expect at least below 30% RH with a 50% chance to get below 25% by
mid afternoon tomorrow. This will largely depend on cloud coverage
through the day and the burn site is most likely to be in the
mostly sunny region for tomorrow. Winds will initially be light
with a variable wind direction tomorrow morning but will
eventually become predominately northwesterly by tomorrow
afternoon. Sustained winds will generally be 10-15 mph with
occasional gusts approaching 20 mph.
