.DISCUSSION...

High pressure centered over Central Florida will keep conditions
dry and winds generally light. Patchy early morning fog, if any,
is expected to dissipate by 10 AM at the latest, and likely
sooner. Winds less than 5 mph will be largely variable through the
day, becoming briefly easterly at around 5 mph after 6 PM as a
weak east coast sea breeze pushes through, then diminishing to
less than 5 mph while veering to southwesterly overnight. There is
potential for fog again tonight into Saturday morning, but
confidence how widespread and dense it will become is low at this
time. Winds Saturday southwesterly to westerly around 5 mph. Rain
is not forecast.

Today`s min RH 45-50% and Saturday`s around 50%. Smoke stagnation
will be possible in the morning due to low mixing heights from a
surface inversion. The inversion should mix out by 11 AM, but this
afternoon`s smoke dispersion values remain poor due to weak
transport winds. Saturday afternoon`s smoke dispersion will be
fair to generally good as transport winds increase a bit.
