No changes planned for the forecast.

Previous...
SHORT TERM /Tonight through Friday Night/...
High pressure will continue to build into the CWA through Friday. 
This will keep winds northwest but diminishing tonight...increasing 
again on Friday with gusts of 20 to 25 mph. Clouds over TN will 
begin moving south tonight...however downsloping should limit the 
coverage with mainly areas of north of ATL/AHN going mostly cloudy. 
Very dry air aloft will clear skies with mixing Friday morning. 
Local bias tables indicate mos guidance low temps at all stations 
have been running 1 to 3 degrees too cold and have therefore raised 
low temps a degree or two.

LONG TERM /Saturday through Thursday/...
Main player in the extended forecast will be a clipper system that 
moves through late Saturday into Sunday. 

The clipper system looks to be moisture starved. However, prolonged 
NW flow against the ridge tops could provide just enough lift for 
isolated showers. Sunday afternoon looks to be the period of 
strongest lift and the best moisture...but the isolated showers will 
linger into Sunday night. The temp/moisture profiles for Sunday 
night do support a change to wintry wintry precip. However, chances 
remain small and moisture is limited, so no accumulations are 
anticipated within the ice/snow grids. 

The next front that comes through the region looks to be on 
Wednesday, but remains a dry fropa at this time. Temps will remain 
fairly close to seasonal values through the period.

FIRE WEATHER...
High pressure will build into the region through Saturday bringing 
dry and stable conditions. Humidities are not expected to reach 
critical levels through Saturday. Winds may reach critical levels 
Friday with gusts of 20 to 25 mph. However fuel moistures have not 
reached 8 percent...therefore a Fire Danger Statement is not 
anticipated for Friday.

.AVIATION...
06Z Update...
Strato cu over TN and northern AL will move across north GA with
the ATL area being on the southern limit of the cloud field.
At this time expect SCT030 this morning but as mixing takes place
after sunrise...the drier air aloft will mix in and the clouds
should dissipate. Expect VFR conditions for the rest of the
forecast all areas. Winds will be northwest and gusty today and
then diminishing tonight.

//ATL Confidence...06Z Update...
Medium on clouds this morning.
High on remaining elements.
