Sounding discussion
The sounding this evening is a warm one for february with a well
mixed boundary layer up to an elevated inversion at almost 700 mb.

A drier airmass is present above, though overall pw is at 1.1
inches. Winds are westerly through the profile. Patchy fog is
possible later tonight and tomorrow morning over land areas. The
most fog will likely be over nearshore water and in river basins.

discussion...

a front is slowly drifting southward today across the southeast. A
few showers ahead of the front developed today and we can expect a
few more showers to be possible tonight. The front really does not
make it through the forecast area thanks to a fairly decent ridge
over the atlantic. After the cold front all but dissipates and
moves north, the foggy mornings should begin to improve for the
beginning of the work week. Temperatures still will remain warm
as the spring like conditions continue through next week. Expect
onshore flow to setup for next week. That will increase the
moisture available in the atmosphere and a few showers can be
expected each day especially over the eastern portions of the
forecast area. The next organized chance of rain looks to come by
the middle of next week through the end of the week. Guidance is
pointing to a prolonged period of unsettled weather for the back
half of next week. A cold front will slow quite a bit as it
approaches the area and stall at some point either very close to
the area or to the northwest before moving back north by Friday.

Heavy rain for some portion of the mid south will be an issue
depending on where this boundary sets up. We will have to watch
this in future forecasts. It does not look like a huge issue for
our forecast area but a good chance of showers and thunderstorms
will be in the forecast for the second half of next week. 13 mh

vfr conditions will be persistent through the remainder
of the afternoon and much of the evening however expect at least
MVFR CIGS and possibly vsbys as well. By 07 08 CIGS will begin to
lower towards ifr and possibly even into lifr status shortly after.

Vsbys will likely fall slower and mainly around coastal sites.

Msy new have the best chance of falling into ifr and lifr status due
to vsbys but can not rule out asd or gpt as well. Cab

front is very slowly sliding south and could eventually
reach the tidal lakes and ms coast. Along this front and just to the
south winds will be fairly light and moisture will pool. Combine
that with the relatively cooler shelf waters and there could be one
more night of fog concerns over the inner waters and tidal lakes. On
shore will take back over by midday tomorrow and could even become
moderate by late Sunday night and Monday. Onshore flow will continue
through the first half of the week. Persistent moderate onshore flow
and southeast winds across much of the gulf will eventually lead to
a decent swell leading to higher seas. Cab

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