Update
Increased pops a bit over the next few hours as a line of storms
to our west continues to weaken as it move eastward. The most
robust convection associated with the line is consolidating
further south and west over southern ms/la where instability is
greatest. Elsewhere the weakening trend is noted with some
isolated re-development along the outflow.

Prev discussion [745 pm edt]
Near term [through tonight]
Mid/upper low will move southward through southern missouri into
western tennessee supporting a surface low pressure area across
northern alabama and cold front stretching southward into the gulf
of mexico. It appears that the front may edge into the western zones
around dawn (se al and far western fl panhandle counties) and bring
a slight chance for showers and isolated storms (better chances
further into the morning Sunday). Low level moisture will continue
to advect in on southwesterly winds which will lead to patchy fog
across SW ga and the eastern fl panhandle and fl big bend areas
where surface winds may become calm. Across SE al and western fl
panhandle, the wind fields will be a little stronger in closer
proximity to the front so less of a chance for fog in these areas.

Otherwise, increasing clouds with lows in the lower to middle 60s.

Short term [Sunday through Monday night]
In the upper levels a closed low moves into al/ga on Sunday and
remains over the region until late Monday night. At the surface a
weak low centered near eastern tn will bring a cold front through
on Sunday afternoon and into Sunday night. Showers and
thunderstorms are likely as the front approaches the region. A few
strong to severe storms are possible in the afternoon and early
evening hours when instability is elevated. CAPE will be good
around 1000 to 1600 j/kg and 0-6 km shear will be decent around
30 to 35 kt. SPC has a marginal risk for severe storms outlined
for the southwestern ga counties on Sunday afternoon/evening.

Highs Sunday will range from low 70s to low 80s. Highs Monday will
be in the mid to upper 70s. Lows will be in the 50s.

Long term [Tuesday through Saturday]
In the upper levels weak ridging will be in place for most of this
timeframe. At the surface a weak pressure gradient will be over
the region this week. There is only a slight chance for an
afternoon shower or thunderstorm late this week. Highs will be in
the 80s. Lows will be in the 60s.

Aviation [through 00z Monday]
Ifr restrictions in ceilings are expected at all terminals
tonight, with some MVFR visibilities possible at tlh and vld. A
line of showers and thunderstorms will move through the region
tomorrow beginning near dhn and exp in the late morning, arriving
at vld near the end of the taf. Some of the storms could be
capable of producing hail and damaging winds especially closer to
aby and possibly dhn.

Marine
Light to moderate southwesterly winds will increase and become
northwesterly as a cold front passes tomorrow evening. 15 to 20
knot winds are expected Sunday night through Monday. Showers and
thunderstorms are likely ahead of the cold front tomorrow
afternoon.

Fire weather
A cold front will move through the area Sunday bringing with it a
good chance of wetting rains. Amounts do not appear very heavy,
generally three quarters of an inch or below and the heaviest
amounts favor southwest georgia. A drier airmass will move into the
region Monday but no red flag criteria will be met.

Hydrology
River levels are currently steady. There will be a good chance for
rain tomorrow as a cold front approaches. Rain totals will likely
be under one inch. Otherwise there is only a slight chance for
rain late next week. No flooding concerns.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
