000 FXUS62 KFFC 241925 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 325 PM EDT Wed May 24 2017 .SHORT TERM /Tonight through Friday/... Complex system moving across the CWA with rotating cells continuing across central GA. Will continue the Tornado Watch for mainly the eastern half of the CWA along and ahead of the main area of convection. Drier air is already moving into western GA and this will continue to be the trend. Will end the pops from the west through this evening, however the cold core H5 low will move over the CWA and this will keep northern GA unstable enough for scattered showers through the night. The H5 low move rapidly into the Carolinas however with daytime heating and the proximity to the cold core, there will continue to be scattered showers/tstorms over northeast GA through much of Thursday. Skies become mostly clear Thursday night and Friday. Winds will be gusty Thursday but should diminish Thursday night and Friday. 17 .LONG TERM /Friday Night through Wednesday/... No major changes for the long term. Previous long term discussion follows... 17 LONG TERM /Friday Night through Tuesday/... Shortwave ridge of high pressure will maintain dry and stable conditions through Saturday, with temperatures quickly bouncing back during the day Sat. Moisture will gradually increase this weekend as W/SWerly flow becomes more pronounced across the region ahead of large upr vortex dropping south from central Canada over the northern Plains/upper Midwest. By Sunday and into the first part of next week, several shortwaves will interact with sufficient moisture and low lvl convg along a west-east oriented frontal boundary to support an increasing chance of shower and a few thunderstorms. This "system" is not looking nearly as impressive as what we`ve been dealing with over the past few days but it will bring the area more rain, on top of what we`ve had already. Drier air moves in from the northwest late Monday into Tuesday with a nearly stationary frontal boundary across north Florida/south Georgia - where lingering chances for showers/storms will exist Tuesday. Temperatures into early next week should remain around normal for late May -- lower to mid 80s for highs and mid 60s for lows. DJN.83 && .HYDROLOGY... Storms with brief heavy rain continue across parts of eastern GA but these are moving quickly and the threat of flash flooding has ended. Will therefore cancel the Flash Flood Watch. && .AVIATION... 18Z Update... Main area of convection over the MCN area and another line of showers and isolated tsra from North GA to near Anniston, AL. These areas of convection will continue moving east. Behind these areas are scattered showers. The scattered showers will move across the forecast area behind the main areas of convection as they exit the region. The precip will be out of the forecast area by late this evening. A few showers/tsra will dot extreme north Georgia tonight but should stay north of ATL and AHN. Cigs mostly VFR into tonight with MVFR cigs will fill into the region late tonight. Cigs will lift and scattered by 18Z Thursday. Winds will be southwest and gusty this afternoon, diminishing tonight and become west and gusty Thursday morning. //ATL Confidence...18Z Update... Low on timing of convection this afternoon. Medium to high on remaining elements. 17 && .PRELIMINARY POINT TEMPS/POPS...
