.DISCUSSION...
Variable winds begin the day today with speeds of about 5 mph.
Winds will turn out of the southeast after 10am with an increase
in wind speeds up to 5-10 mph. No strong or sharp wind shift are
expected today, but some terrain induced variability may be
possible given the light nature of the winds.
High temperatures will warm to the mid 60s, resulting in relative
humidity down to about 25% late this afternoon. Smoke dispersion
will be fair through the morning given light winds through the
mixing layer. Improvement is expected by the afternoon, but
transport winds are still expected to remain under 10 mph at
times.
