Synopsis
An approaching cold front will move into the region overnight
into Saturday. The front will stall just south of the area
Sunday. A system off the florida coast through the weekend will
move northward and off the southeastern coast early next week.

This will help to keep a chance for showers and storms in the
forecast.

Near term through tonight
This afternoon: a moist southerly flow will continue across the
region with a cold front remaining off to the north of the cwa.

Weak shortwave is moving through the midlands, and this has
helped to kick off convection across much of the CWA already
early this afternoon. The air mass is forecast to become
moderately unstable. Shear remains weak, so only a marginal
threat for any severe weather. Pwat values currently just below
2 inches, and thus can not rule out heavy rain potential. High
temperatures are expected to range from the low to mid 90s.

Tonight: the main cold front will move in from the north tonight
as high pressure off the southeast coast continues to direct
moist air into the forecast area. Scattered showers and thunderstorms
can be expected through the early portions of the overnight
hours. Models do seem to indicate there may be a lull in the
rainfall later tonight. Pwat values at or above 2 inches, so
heavy rain will remain possible through the night in any
stronger activity. Lows tonight will again be in the low to mid
70s with good insulation.

Short term Saturday through Monday
A cold front stalls over the midlands and csra this weekend.

Precipitable water values at or above 2 inches and the potential for
thunderstorms training along the frontal boundary from west to east
raises the risk of flash flooding. Wpc has the region in a marginal
risk for excessive rainfall on Saturday. Rainfall amounts of 1 to 2
inches with locally higher amounts will be possible. High
temperatures will be 5 to 7 degrees below normal due to rainfall,
extensive cloud cover, and the intrusion of cooler air. The frontal
boundary becomes more diffuse on Monday with a much lower
chance of precipitation.

Nhc continues to monitor invest 98l for tropical cyclone
development. At this time model consensus keeps any potential system
off the ga sc coast through early next week.

Long term Monday night through Friday
A potential tropical system moves away from the sc ga coast by mid
week. A westerly flow aloft should lead to a more typical late
summer diurnal convective pattern. Temperatures are expected to
warm into the low to mid 90s for highs with lows in the low to
mid 70s. Precipitable water values remain near 2 inches with
some drying possible in the western midlands.

Aviation 18z Friday through Wednesday
Isolated to scattered showers and thunderstorms have developed
across the region as a shortwave moves into the central
midlands. Have included mention of vcts all TAF sites through
this evening, and have gone with a tempo for thunderstorms for
the near term. Brief periods of MVFR ifr may be encountered
with the stronger activity. Late tonight as the front moves into
the area, cloud cover will be on the increase, and ceilings are
expected to begin lowering. Models indicate low endVFR ceilings and
potential MVFR visibilities. Showers and storms will once again
develop across much of the CWA on Saturday, and have included at
least vcsh beginning late morning.

Extended aviation outlook... The chance for showers and
thunderstorm along with associated cig vsby restrictions will
remain through the weekend associated with a cold front. Late
night and early morning fog stratus is possible Monday and
Tuesday.

Cae watches warnings advisories
Ga... None.

Sc... None.

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.
