Discussion
We are starting to see a few showers along the nature coast out
ahead of a cold front that will push through central florida
overnight. It looks like it has the upper level support to make it
through however is will make a hard stop in south florida as it
runs into the subtropical ridge. A few showers will be possible
through the rest of the afternoon and evening mainly north of i-4.

Showers will be hard to come by however and I have kept chances
mainly around 20 percent. By Wednesday the front should be south
of most of the area with the only exception being charlotte and
lee counties where the front should be right over the area. This
will give us a break from the humidity and will drop our
temperatures to around average in the low to mid 80's.

This relief of the humidity will be very temporary as the front
will start to drift north again and we will see a very similiar
setup to what we had on Monday. That means the front pushes to our
north and the humidity and scattered showers return quickly.

By the weekend another cold front will attempt to make its way
through florida but will ultimately fail and stall along the
nature coast. This means the same humid and warm pattern with
scattered showers will continue through the weekend and early next
week.

Aviation
Vfr conditions will continue through the TAF period. However,
winds will be shifting through the period. We have started out
with southwest winds this afternoon which will shift northwest to
north overnight before turning northeast tomorrow morning. Winds
should remain below 10 knots.

Marine
A weak cold front pushing through the area overnight will help to
shift winds to a more northerly direction and will result in
winds increasing. Our central and northern zones will be under an
exercise caution overnight as winds increase to around 15 to 20
knots. Winds will shift to an easterly direction starting
Wednesday night and we will remain breezy with exercise caution
possible Wednesday through Friday with winds right now expected to
be around 15 knots.

Fire weather
Fire weather concerns remain low as values remain above critical
levels through the week.
