SHORT TERM /Today through Tuesday/.
Current satellite loop shows some Mid to Low level clouds streaming across the SE ahead of developing approaching frontal system now over the Central and Southern Plains states. The cold front will make its way through the Central and Southern MS river valley today with a line of severe showers and thunderstorms. This front will push into NW GA just after sunset tonight with showers and thunderstorms moving into the state. Before the system arrives temperatures will increase into the unseasonably warm mid-60s to mid- 70s. With such warm temps and moist southerly flow we will see some isolated prefrontal showers today, but precip chances dont really increase until the front arrives. As this front moves out of the MS river valley This evening the Hi-res/short-term models are continuing to show an overall weakening trend with this system. The over all organization/intensity weakens some as broken line of showers/storms approach northwest and west-central GA between 8 pm and midnight tonight. However, low-mid 60s dewpoints yielding just enough instability along with 40-50kt low lvl (0-3km) winds to support small pockets of organized convection that could result in strong to damaging winds and perhaps even a brief/spin-up tornado. Axis of heaviest rain with this system will be across north GA where a more prolonged period of heavier rain is likely. As much as 1 to locally 2 inches is expected with lesser amounts south/east of I-85.
Risk for severe includes areas mainly across West and NW GA through daybreak Tuesday morning. There will still be a potential for a few stronger storms across east/central GA Tuesday afternoon as the system exits the area. However, weakening low lvl wind shear and overall support should end overall severe threat across these areas.
As this system exits the area Tuesday afternoon, gusty northwest winds 15-30 MPH will usher in a much colder and drier airmass.
LONG TERM /Tuesday Night through Sunday/.
Models agree on a strong cold front pushing east of the forecast area as the long term begins. Have continued with low pops in the far east central counties for Tuesday night. Tuesday night into Wednesday should be dominated by gusty winds and strong cold advection. Temperatures should moderate some for Friday as an upper ridge builds briefly over the southeast. Southwest flow aloft ahead of the next upper trough will bring rain back into the forecast area for Friday night into Sunday. GFS and ECMWF diverge on evolution of features for the weekend. The ECMWF is deeper and slower with the southern stream trough while the GFS sweeps the system off the Atlantic Coast by Saturday afternoon. To compromise with these differences and to blend with surrounding offices . pops have been continued for much of north and central GA through Sunday.
06Z Update .
MVFR to VFR ceilings across the area this morning with light SE winds. Ceilings will fall a bit more through daybreak with some IFR reading across the area. The ceilings will lift back into t he MVFR range the VFR by this afternoon. Winds will stay out of the SE at 10kt or less today but as the frontal boundary moves a bit closer winds will increase out of the SW with 10-14kt gusting to 20kt. tonight into Tuesday morning. Precip chances slowly increase across the area from NW to SE but not expecting any precip at the ATL area sites until after 00z Tuesday.
//ATL Confidence . 06Z Update . Low confidence for ceilings heights Medium to high confidence all other elements.

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.
