Aviation...
VFR will prevail during the next 24 hours. Clear skies
early this morning will give way to scattered to broken

then across the southern ones after 17z as low level
moisture increases across the area, with some additional
mid/high clouds aoa 100 streaming in from the Gulf. Light
and variable winds early this morning will become southwest
and increase to 7 to 10 knots after 15z then diminish to
around 5 knots or less after 02z tonight.

Update...
a near zonal flow is in place across the region this
evening, with some mid and high clouds streaming eastward
into the central Gulf of Mexico. High pressure remains in
place at the surface. For tonight, this high shifts eastward
a bit, allowing low-level winds to become more
southwesterly. This in turn will lead to an increase in
moisture and some additional cloud cover intruding into the
northern half of the forecast area by sunrise. There could
also be a few showers before dawn, mainly across the
northern Gulf waters and the northern Nature Coast region,
but this is a fairly isolated chance so will keep pops at 20
percent or less. Other than that, really not a whole lot
going on weather-wise across the local area. Temperatures
will bottom out in the 40s and 50s tomorrow morning,
generally a few degrees warmer than this morning. No major
changes needed for the evening update.

Marine...
high pressure over the area will shift eastward through
Thursday night ahead of an approaching weak frontal
boundary. Southwest winds will become more northerly and
then northeast Friday and Saturday behind this front. High
pressure will then settle back over the region for the end
of the weekend. No headlines are expected for the next
several days.
