Hazardous marine and beach conditions continue...

Discussion
A deep low over the southern appalachians... With a mid level trough
down above fl and a cold front stretching through east fl coastal
waters... .Early this morning slowly tracks to the mid-atlantic coast
by late sun... With the mid level trough and front swinging out over
the atlantic. As these features depart broad deep layer ridging
slides eastward across the gulf region.

For the remainder of the weekend - stable and drier air begins to
filter in. However there will be enough moisture along with a couple
of weak troughs rotating across the area for some showers to scoot
through at times. These will be isolated and light and end this
evening... With Sun rain free. Temperatures will be on the cool side.

The main concern will residual large wave action on the gulf waters
continuing to create some high surf and dangerous rip currents.

These start to diminish later tonight and early sun.

During mon-fri - the deep layer ridging eases eastward and flattens
somewhat over the southeast u.S. Coast for the end of the week. This
is in response to a short wave trough over the southern high plains
that develops in to a deep low when it arrives in the central gulf
coastal states. A stable and generally dry airmass prevails for most
of the week. By Fri the lower level flow has shifted to southeast
and south... Returning adequate moisture for some showers and
storms. Temperatures just below normal Mon warm to above by fri.

Aviation
20 06z tafs.VFR with a sct LCL bkn deck AOA 5k. W winds become nw
and remain gusty. A rouge shra ra may track near over the terminals
but with little impact.

Marine
Departing low pressure and approaching high pressure will maintain
a tight pressure gradient into this evening with small craft
advisory conditions on gulf waters. Winds have slacken some on
tampa bay and charlotte harbor with a exercise caution headline
in place. The high tracks toward then over fl by midweek with
winds diminishing and veering.

Fire weather
Very robust 20 foot and transport winds will create very high
dispersion indices across the area today... Winds then begin to
diminish. Drier air working will will locally drop minimum rh
values below 35 percent Sun and mon. However light winds will
preclude any red flag conditions. There will be a slow and subtle
moisture return through the end of the week.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
