Short term /tonight through Friday night/
Progressive pattern will continue through the short-term as an omega
block remains anchored over western europe. Current water vapor loop
shows the center of a strong closed mid level low over southwest
missouri... With several shortwaves rotating about cyclonic flow to
the south of this main low. This system is being pushed east by
potent... Digging trough across the western us. Analysis of latest
sfc data reveals developing low pressure across eastern missouri and
associated cold front draped south through lower mississippi valley
into the western gulf. Warm front extends east and then southeast
across oh valley and into southern appalachians... Where it basically
marks the wedge front boundary from high pressure ridge extending
down eastern us from canada.
Radar mosaic beginning to finally light up to our west... While
activity continues to our east along and ahead of the wedge/warm
front. Large complex of thunderstorms across gulf coast has been
slow to move today... And is showing somewhat of a weakening trend.
Evolution of this activity into the evening hours introduces
forecast uncertainty... With many factors at play.
Spc mesoanalysis continues to portray dual jet dynamics across the
northern gulf where right entrance region of polar jet
/associated with main closed low/ and left exit region of
subtropical jet /associated with southern shortwave/ are helping to
aid the gulf coast complex. As this system continues to push east
into our area... Heights will continue to fall and broad scale ascent
will increase. Right now... Indications are for the dual jet to
weaken as closed low moves northeast and southern wave moves east.
This would act to weaken the storm complex over the gulf and not
completely shut off our moisture transport. However... There is the
potential for left exit region of subtropical jet to sustain the
complex into the fl panhandle and rob us some moisture.
However... As/if these processes occur... Main closed low will take on
a negative tilt... Which will enhance lift across a good majority of
ga... Regardless of gulf evolution. So... All in all... Evolution will
be a matter of which process is dominant.
With the above in mind... Storm development /supercellular in nature/
has already occurred across southern al out ahead of the gulf
complex. See no reason why these storms will not sustain themselves
through the daylight hours as adequate insolation has resulted in at
least 500-1000 j/kg mlcape. These storms will carry severe potential
should they move into western/sw georgia later this afternoon given
increasing shear amidst unstable airmass. Think eventually discrete
activity will evolve into a cluster of thunderstorms /given veer-
back-veer wind profiles/ and move across majority of the area
overnight tonight into very early Friday. Regardless of discrete or
line activity... .Potential will exist for severe activity through
much of the overnight hours... .Just hard to say where exactly
largest threat will reside. All threats will be possible:
wind... Hail... Tornadoes. Will also monitor line of storms along the
cold front currently in western tn valley... As this activity will
have strong lift to support it as it moves east tonight... Though
aforementioned activity make have a negative effect on it.
Should see rapid clearing of precip Friday with perhaps some cu
lingering in the wake of the cold front. Surface high pressure will
be building in from the north Friday so expecting a pleasant
day... Which will continue into the extended.
Long term /Saturday through Thursday/
Forecast looks on track with the next system arriving Monday.
Model difference in location of the low will ultimately impact
thunderstorm coverage and severity. However, it is safe to say we
will be receiving beneficial rains Monday into early Tuesday.
Models are weakening the system for mid-next week. Above normal
temperatures through the period.

warm and sunny weather returns just in time for the weekend with
upper ridging in control. Temperatures will be well above average
both Saturday and Sunday with highs by Sunday nearing 80 in north
georgia and well into the mid 80s in central georgia.
The tranquil weather comes to a quick end as the active pattern revs
back up. By late Sunday clouds will begin increasing ahead of the
next storm system with rain close behind. This next system will
follow a more southerly track than previous systems. The GFS brings
the surface low across southern tennessee into north carolina on
Monday while the ECMWF is a bit slower and farther north with the
center of the low. Regardless, expect widespread rain and
thunderstorms to overspread the area on Monday. The potential for
strong thunderstorms as well as heavy rainfall will also be a
concern during the Monday time. As the upper low passes overhead or
just north of the CWA Monday night into Tuesday morning, wraparound
rainfall can be expected into at least part of the day Tuesday.
Wednesday looks largely dry at this time, but the break in
storminess will again be brief as the progressive pattern continues.
The next storm system will already be knocking on the door of the
area, though there are model discrepancies with the timing.
Nonetheless, showers and thunderstorms will returning by the
Wednesday night into Thursday timeframe.
initial showers/storms and some possible MVFR cig and vsby
lowering pushing north across TAF sites this evening. Have tempo
for tsra initially from about 01-05z and may need to extend later
if another area develops to the west of the current zone. Expect
MVFR CIGS hanging around through the morning though cannot rule
out a break between precip areas. Winds initial ssw 7-12 kts and
some gusts becoming more west for Friday at 10-15 kts gusting
20-22 kts. CIGS should have some lifting/scattering by 18z Friday.

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.
