000 FXUS62 KFFC 281128 AAA AFDFFC Area Forecast Discussion...Updated National Weather Service Peachtree City GA 730 AM EDT TUE JUN 28 2016 .SHORT TERM /Today through Wednesday/... Somewhat tricky forecast today. Models all seem to want to push the better moisture and POPs too far south a little too soon. Old trough remains draped across the forecast area this morning...but plenty of moisture remains north of the trough and diffluent upper flow still dominates the region. I have used a general model blend for POPs but adjusted the better chances northward to start and slowed the shift of the better POPs toward the southeast a bit through the day. Still looking at good chance to likely POPs most areas at some point during the day...early up north and later across Central Georgia. Instability is marginal for any strong to severe storms today. Trough settles into Central Georgia tonight and Wednesday with continuing chance POPs across the southern half of the forecast area and only slight chances at best across the north as drier airmass eventually works into that region. 20 .LONG TERM /Wednesday Night through Monday/... Models in good agreement through the long term. The eastern H5 trough will continue to have weak short waves moving rapidly through the flow. This will be enough to continue the risk of thunderstorms to parts of the CWA...mainly south of the fall line. As the eastern trough flattens this weekend...a ridge of high pressure will build into the Gulf of Mexico spreading moisture into the Southeast U.S. This will increase chances of thunderstorms across the CWA Saturday through Independence Day...with the highest chances across north Georgia. 17 && .AVIATION... 12Z Update... Wide mixture of VFR to IFR or lower conditions are expected to continue through around 14Z...becoming VFR outside of scattered convection through the majority of the remainder of the forecast period. Isolated to scattered convection across far north Georgia currently will become more widespread after 14Z. Winds have been light and variable...06kts or less...but will increase into the 6- 10kt range and become generally northwesterly between 12Z and 14Z. The northern half of the of the area will see winds moving over to northeasterly and increasing into the 8-12kt range between 18Z and 00Z before diminishing once again after 00Z. //ATL Confidence...12Z Update...
